I'll get some pictures in here soon. Currently waiting on the w/m solenoid to stop her from siphoning and get her running a bit better. Have a short list of things that need fixing, leaking intercooler piping, leaking valve cover gasket, she's underboosting and not even hitting wastegate pressure and the water meth.

Looking good! I'm sure it feels great to have everything coming together!

[canadianA4B7]

Another EFR happy to see!!

Not sure what boost your going for but I’ve had to replace all the IC clamps to keep the boost in. Some of those flat style clamps have not held in place against the boost.

[theguysinger]

Oh man, I love seeing these builds with EFR’s on them. Subbed for lots of boost :D

[viperdsa]

Took forever to get to this point and I'm just happy to have it back from the shops.

Not sure what's up with the boost it's only hitting 9psi, with a 14psi wastegate spring. The leak from the intercooler doesn't look nearly big enough for that kind of leakage. Through another mm of preload on the wastegate and was waiting for the solenoid before taking it back out and seeing if there was much of a change.

What kind of clamps did you go to Canadian?

Got the solenoid installed today. Idles so much better. I'm gonna have her smoke tested then start pulling logs for Motoza and start getting her dialed in.

Nice build!
Do you have more pics of the exhaust manifold? Can I ask what you paid for it?

Replaced some gaskets and re routed the dv lines so it is just directly connected to the intake manifold and not the N249. Builds more boost but still only gets to 11psi. Ordered the same pressure tester i3oricua used and gonna see if I have any crazy boost leaks.

That boost leak tester will make things easier at home for sure. All you really need is a compressor of some sort. Glad to see someone else doing the EFR. My tuner kept trying to get me to go K04. I refuse and now will use a different tuner since he won't respect what I'm trying to do.

[viperdsa]

Disconnected the n75 from the wastegate just to see what it would do. It made all kinds of boost. So it would seem the n75 or something related is my problem.

Did you get an overboost code? Could be you were just running off of wastegate pressure so it’s based on whatever spring you have in the wastegate. I guess I’m assuming you have an external wastegate. I’ll up have to scroll up. If that’s the case then it could be N75 or your tune or lack of. For once I’ll echo what Evolution would say and do some logging of your N75 and see what requested vs actual is.

Don’t these EFR turbos have what they call wastegate canisters? High, medium and low? Isn’t default medium?

Maybe a different one is necessary.

I'm using a single port Turbosmart IWG with a 14psi spring and i think 5mm of preload.

I logged it a few weeks back and if I recall correctly it was requesting 1.5bar. I have some codes to clear that were there prior to the wastegate experiment so we'll see what is there, and probably log it again with the n75 attached.

Call your tuner and ask them what type of crack pressure the tune is expecting and set your wastegate up so it responds to what the software is expecting. Log your N75 duty cycle and adjust it if necessary. If you’re getting high N75 duty cycle you might want to add some more pretension. Do a log of 003, 115 and 119

[viperdsa]

Pulled codes and they are the same two that I have been getting P2188 and P0507.

Its Motoza's BT tune, so its a pretty custom job Dave probably specs out based on the equipment. I doubt viper pulling logs is going to help a ton, he should focus on eliminating leaks and making sure the N75 is functioning properly.

OP - That manifold is beautiful. Was just perusing their Instagram, thats some phenomenal welding!

Sounds like you have a vacuum leak somewhere but the confusing thing is that your getting a rich condition code and not a p0171 which is a lean condition code. I’m pretty positive you have a vacuum leak but I’m not sure if that will make both your codes go away. That leak tester should be helpful when it arrives.

Are you using the boost prv on the turbo compressor manifold?

And did you purchase the high boost PRV spring for it (20 psi +) if not I likely am the only one that can ship this out ASAP it too Borg Warner 6 months to get this out the door so I ordered 2 in case this happens to someone else.

Custom tune = pulling logs helping a ton. Especially when trying to see if the N75 is working properly. I’m assuming this is a base file that is expecting certain parameters and are tweaked from there. Getting in touch with Motoza and finding more info about what the base tune is expecting seems like the best way to go.

Wastegate crack pressure/pre tension was a huge obstacle for me when it was set to HALF of what it should have been from the manufacturer and it took me forever to figure out that it was set wrong, and that was with only a K04. Pretty standard set up. It would seem a simple phone call could set that straight. Especially since these EFR turbos have pretty customizable wastegate set ups. It’s not like a K04 where 8-10 psi of crack pressure is pretty standard. There is no real standard with EFR’s since they have a low, medium or high wastegate canister available.

Could the fuel trim codes be caused by a faulty throttle body? It might not be a bad idea to check block 60 at idle and make sure throttle position and valve position equal 100% when added together. I’d try a TB alignment too.

[viperdsa]

Canadian: I did not get the high boost prv spring. I swapped the stock prv with a turbosmart kompact plumb back valve. When I disconnected the wastegate from the n75 it held 20+psi fine.

Pulled a log using Motoza's program so it has pre-determined things it pulls. N75 duty cycle was around 40%. Boost actual vs boost requested we're interesting. It was requesting 2.2bar and said actual was 1.8bar. While my boost gauge was reading 11psi. Wondering if my MAP sensor might be on it's way out.

I'll try the throttle body alignment because there was a lot of hassle getting the water meth plate to seal. Going to send in the little log I did to Motoza's on Thursday and see what they think.

Pressure tester gets here Thursday. I know I have a pin hole in one of the fabbed intercooler pipes, but I don't think that is big enough to cause these issues.

My guess is a bad sensor or possibly a bad ground somewhere in the bay. I'd give the grounds a double check for tightness just to eliminate that common and stupid goof people make reattaching stuff in the engine bay when they're moving too quickly.

That spot that you’re talking about with the meth plate and the throttle body is exactly how I kept getting my p0507 code. I had a pretty large leak on one corner but it also caused a really rough idle. Those threads for the intake manifold where the throttle body connects strip very easy.


Sent from my iPhone using Tapatalk

[EvolutionArmory]

You usually need to subtract atmospheric pressure from your log to really see what boost pressure really is. So your actual boost of 1.8 bar (26 PSI) is actually 11.3 psi if you subtract atmosphere (14.7 psi).

So your tune is really asking for 17.2 PSI but actual is really 11.3. I’d adjust your wastegate a little more and see what happens if you aren’t bleeding boost at your throttle plate.

And all of that needs to be done after you do a boost leak test and seal any leaks you do find.

Just spit balling.

Sent from my iPhone using TapatalkYeah, I have a feeling I probably have a leak there. The shop that did the water meth install couldn't get the IE water meth plate to seal with 3 different gaskets. So I got the CTS plate which uses an o-ring and they said that they were able to get that one to pass a smoke test. Guess I'll find out Thursday.

What I do for that specific section is I helicoil the threads and it seals amazingly well. I recommend doing this or you may never get that area to seal which i suspect you have a leak from.

I don’t know if your boost is holding well but what I would guess is probably happening is that you hit peak boost right away and it falls off really fast because of that leak. Just a theory. You might have other problems as others have listed here.

Hey, when you said your duty cycle was 40%, for how long was it 40%? If your duty cycle starts out really high, drops really low and climbs right back up again 2 things are most likely happening. You have a good sized boost leak and your car is throwing more boost at it to try to compensate making the duty cycle high at high rpms or your wastegate is set up wrong and it’s not staying shut long enough during ramp up.

Here’s my worst N75 log when I was figuring out my issue.

Hit 35% at the low, was in the 50’s and 60’s for a bit but climbed up to 90 at the end.

Here’s a better one that stays in the 60’s for most but spikes at the very end. This is pretty acceptable

I'd have to go log a full pull and pay attention to it. The pull I'm thinking of was only 3-4k in 4th, and it didn't move anywhere.

Little south of Denver. My car as it is now wouldn't be the best representation of how an EFR will be up here. Between my boost leak and the fact that it is still on the base file I was sent, and have not had any revisions done yet.

[viperdsa]

Well evidently my pinhole in my intercooler pipe is bigger than I though. Could barely get the system to pressurize to check for leaks. That hole gets fixed tomorrow then the search for more leaks continues.

[viperdsa]

Got the intercooler pipe fixed today. Pressure tested the system and the only two things I heard was what sounded like a leak if I put my ear to the valve cover; and the sound of oil bubbling. The PCV was good, tried the new one that I got from Audi last week and it leaked, so went back to the one that was on the car.

Went and pulled a log. Thought I blew a coupler during a 3rd gear pull, but didn't see anything disconnected or torn hose so I think it was limp mode. Didn't throw a CEL, gonna go for a drive later to see if it is the same and if I need to go search more thoroughly.

Even with the pipe fixed still only making 10psi of boost so gonna send the logs to Motoza and see what they say.

[EvolutionArmory]

Here’s a tip on boost leak testing. Remove the PCV hose from the intake manifold and make a cap for it. I used an old PCV hose, took the hose section off and put a rubber plug on the end of the connector. The perfect cap for the job. Then you won’t have your cylinder head pressurized. Just your intake.

[EvolutionArmory]

Once you make absolutely sure your intake is leak free, do a Log of 003, 115 and 119. If your boost looks like this and your duty cycle is through the roof, you probably need to do some wastegate tweaking.

This was with my wastegate set 4 psi lower than it should be. It wasn’t staying shut long enough to build boost so it was bleeding it off and not reaching full spool til 4K and dropping off real fast. This is only a K04.

With the right wastegate settings I’m now hitting 25 PSI before 3K and holding 20 til 6K before it tapers.

Here is my second gear boost log since my third gear pull was abruptly halted. N75 duty cycle peaked at 44 at 2240rpm and settled at 32-33.

Edit: Still getting P0507 and P2188, also just got P0191. So that may be why I hit limp mode. Everything points to there still being a leak somewhere, I just couldn't hear it.

[EvolutionArmory]

For your P0191 code, check to see if your fuel rail pressure sensor is plugged in, has broken wires or maybe replace it. When that sensor fails it tells the HPFP to run at a pre determined pressure as a fail safe.

Did you replace it recently? Did you use the right one for your engine code? There’s 2.

I don't care man lol. It probably is still faster than my K04(granted its on jacks at the moment). I am curious to see how it spools and feels around town even on a base file. If you ever need log help let me know

I think a lot of people in this forum would lose to you in a race. You’re making big turbo power on E85 (400ish crank), have instaspool with the K04 and stupid torque. If I had E85 anywhere near me I’d just clone your set up and never think about going BT. Have you taken it down the strip with how it is now? Probably runs 12’s.

7163 shoupd outspool both. The 6258 is really close but top end the 7163 will carry boost longer. Twin scroll will change a lot of characteristics of many turbos. I’ve done quite a bunch of stuff to make the 6758 spool lower and I think I’ve got it sorted out now. Someone should twin scroll the 2863 (or it’s newest replacement) I cud hit 26 psi around 3500 rpm with that thing and it pulled like a banshee anywhere in the rev range any gear it was always pushing lots of air never ever did I question if I’d get moving really quickly.

I'm sorry but you're mistaken, the G25-550 is already as fast as a Gen2 GTX2860r and that is with a .72a/r and I have my eyes on the .49a/r which will be even faster spool. I can't find anything about the EFR 6258-G twin scroll which could possibly be even faster.

Below is the G25-550 .72 a/r (I want the .49 a/r version) overlaid with the Gen2 GTX2860R, another 60mm turbo. As you can see, the surge lines (left side of map) are almost identical below P2/P1=2.3 or about 19 psi. That means you can expect similar spoolup with both turbos on stock displacement. However, the G25-550 can produce an additional 75 HP up top (425 versus 500 HP). This make the G25-550 the better choice in the 60mm category.

I asked ATP if they could test fit the G25-550 .49 a/r on their existing manifold for our platform, they came back the next day with these photos.

"Our dev team took a look at this as promised.

In the pics, you'll see the G25-550 with the .49 A/R turbine housing
bolted up.

The turbo is shifted around a bit but it's possible that it will work.
The actuator does run into the motor mount bracket but we can find a way
around that. Next week, we will continue to look at this and determine
if the downpipe position is just too far off to accommodate. Just
wanted to give you an update.

Thank you,"

Got the first revision of the tune today. Dave said he cleaned up the fueling and added some n75 duty cycle, and didn't see any signs of a leak on the logs.

Car idled much better when the motor was cold and saw 14psi of boost. Car is still adapting so we'll see if it makes any more. It still has issues finding a happy idle after driving for a while, it wavers between 1k and 1200rpm.

Have a fair bit of driving to do tomorrow so we'll see if the P2188 and P0507 come back.

[EvolutionArmory]

60% duty cycle is a good place to be in the middle of a log and if it starts to climb a little at redline is OK too. With a bigger turbo like that I don’t think it should have any problem flowing air at redline so I’d expect your duty cycle to be around 60-70% up top. Have you done a boost and N75 log since the revision?

If your tuner can add more duty cycle and get it to be within 60-70% at redline, I think your boost logs will fall in line with each other.

If you look at my log on the first page my car’s duty cycle is about perfect until about 6K before it climbs. This is happening for 3 possible reasons. I either have a turbocharger that is going out of its efficiency range, my wastegate could use another tweak or I have a post turbine exhaust restriction and could maybe lower duty cycle a little up top simply by going from a 2.5 inch downpipe to a 3 inch.

If your duty cycle is still in the 50’s you still have a ton of headroom and your wastegate isn’t staying closed long enough to get your turbo spinning fast enough to generate the boost your ECU is requesting.

Would you mind posting more photos of the turbo/manifold fitment ? Any clearance issues to speak of ? I am in contact with Peter and considering him building me the same one.

Sure, I'll grab some later tonight. The only thing that he mentioned was that he had to do a custom oil drain. The only thing would be where the coilpack harness is routed is pretty close to the downpipe.

[viperdsa]

Just looked through the new log. It's closer to requested, MAP hit 2bar, was requesting 2.3. N75 duty cycle was 47% for the whole pull. Still stumbled a little on the 3rd gear pull so I got out of it. Car is going in to get smoked tested next Friday. I still think there is a leak somewhere on the driver side of the motor.

If there was a easy way to get your tune(not sure UM ever finalized your Golf R software tune) I would consider going k04 to simplify everything, your numbers are really damned good. Would save me/others a ton of money, too.Unfortunately I haven't talked with the guys about my UM tune in awhile. But the car is going back under the knife for general maintenance and parts add on in the next few weeks. I think UM might do a cable now

Are you running a Mafless tune or is the MAF relocated somewhere?

[viperdsa]

The MAF is relocated. You can just see the block where it is on that last picture below the breather tube

[EvolutionArmory]

Have you done any MAF logging? Check to see if it’s around 2.5gs at warm idle. If it’s way above or below that, you could have a bad MAF. What is your peak MAF reading?

Rule out your MAF and look at other things that control fuel trim like your front O2 and MAP, assuming you absolutely ruled out vacuum and exhaust leaks.

Did you replace your O2 sensors when you threw that turbo in there or did you reuse your old ones? When I got my GIAC tune they recommended I replace anything fuel trim related that was old 😀

[viperdsa]

Didn't replace the O2 sensors. MAF readings were bouncing from 5-8 at idle. Gotta look at the logs to see what peak was.

Edit: Peak MAF was 141. Also the shop wanted to see how the car ran with the MAF unhooked since I was getting both rich at idle and rpm higher than expected at idle. Unhooked the MAF and the car ran lean at idle and felt smoother everywhere else.

[EvolutionArmory]

That’s a big problem. Your MAF readings are screwy. To put it in perspective, your readings at idle are more than twice what they should be and half of what they should be at WOT with that big snail on there. Your car is making stock peak MAF 🤣

[Charles.waite]

Yea should be 2-3 at idle.

[viperdsa]

Hmm, wonder if the MAF scaling is off. Ordered a new MAF and we'll see if that helps.

[EvolutionArmory]

Is your MAF housing bigger than stock? It could be tune related if it is.

[Charles.waite]

I would think Dave at Motoza would have MAF scaling sorted out, they’re hardly new to the Audi tuning game. But you never know.

[EvolutionArmory]

Nope, you never do know. We’re all just trying to make educated guesses. I guess that’s all diagnosis is. 😀

That would be easy enough to find out with a phone call. If he uses different MAF scaling he would be able to tell him what the readings should be like. His current readings could explain the lean code at idle though.

Since his has been relocated, the first 2 things I would do is make sure it’s not dirty or installed backwards. I don’t know if being installed backwards is even possible on his relocation housing though. Then I’d call the tuner and ask if the sensor should be replaced.

[EvolutionArmory]

But the rule of thumb for MAF readings is 1gs per liter of displacement at 500 RPM. So our cars are 2 liters and idle at around 750-800 RPMS so 2.5 +/- is what it should be reading under factory MAF scaling. Not 5-8. This is most likely MAF related. Especially since it’s registering WOT values lower or the same as a stock car.

[viperdsa]

The housing is bigger. The inside diameter of the intake is 2.837"

Sent from my moto g(6) using Audizine mobile app (http://r.tapatalk.com/byo?rid=87676)

[EvolutionArmory]

Since you ordered a new MAF we will know the answer soon enough. I’d recommend that when you install the new one, make sure the sensor isn’t installed backwards. Make sure the D section on the connector is pointing towards the turbo inlet.

And make sure the wiring for the MAF sensor is good while you’re at it.

[viperdsa]

Replaced the MAF and it is still acting the same. Motoza is reviewing the logs today and I will hopefully have a new revision this afternoon to try.

[viperdsa]

Car went to Audi to have them leak check it. They didn't find leaks, but the tech that was doing the work said that since I no longer had the check valve from the valve cover to the intake I should be using a different pcv. The pcv that Audi used is for a 2 valve setup, the one he suggested was a VW part and was for a 1 valve setup. It completely fixed my lean, rough idle with the MAF disconnected. Gonna hook the MAF back up later and go pull some logs and see if it helped those.

121337

Top is the PCV he suggested I go to, bottom is the one that was on the car.

Edit: Just got back from pulling the logs. Idle MAF readings look much better. Uploaded the logs so we'll see what Dave thinks.

Sent from my moto g(6) using Audizine mobile app (http://r.tapatalk.com/byo?rid=87676)

[EvolutionArmory]

So he’s telling you to run the PCV valve for a 2005.5 and early 2006 A4. It’s the R revision valve. It makes sense since your PCV system isn’t stock anymore.

[viperdsa]

Yeah. Using Shiro1745's image, with the stock setup there is a check valve in the hose that connects to 1-r. Since I wasn't using that hose anymore I didn't have that check valve, which I needed. So the R revision has that extra valve in the PCV itself so you don't need that check valve at 1-r.

[viperdsa]

Got a new revision today. The MAF got rescaled a little and and little more duty cycle got added. Went for a little drive and it feels pretty good. The car will still die on occasion coming to a stop, or have brief trouble finding idle. Gonna let it adapt for a few days then pull some logs. Sounded like the next revision should start turning up the wick.

[aluthman]

Have you considered MAF placement as a possible issue?

[viperdsa]

I did think about that initially, especially since the MAF is fairly close to the bend in the intake. With the MAF reading more inline with what it should be after the pcv change though, I think that was the main issue.

Not much for updates. Got a new revision Thursday, car still dies coming to stops every now and then. Got a soft code for P1093 didn't throw a cel. Ordered some new underbody panels that have been torn up and a turbo shaft speed gauge.

Threw P0016 and P1093 today. So back to the shop it goes.

p0016 could be your N205

[viperdsa]

Might replace that then, unhooked it and it looks like it is leaking oil into the connector. I cleared the codes and they haven't come back. The car has been running fine, tune still needs to get sorted some. Goes real rich when you let off the throttle and if you have to come to a stop in that time when it's rich the car will die.

[viperdsa]

Nothing crazy to report. Replaced the N205. Got a new tune revision and sent some logs back today so hopefully will have another revision next week sometime. The car has been going really rich occasionally when coming off the throttle and it starts engine braking. Every now and then the car will die coming to a stop, which might be the source of my P0191, or the sensor is causing it to dump fuel when it shouldn't and kills it. Also need to finish the install of the turbo shaft speed sensor.

Other than that have been thinking about LPFPs and a PM4. PPT's basket is nice but probably a little over kill, so I'll probably just go with a TTRS pump when it's time to upgrade it.

[viperdsa]

Maxed out the stock lpfp. Ordered a walbro 450 from PagParts with their basket. Will be getting a torqbyte PM4 next month and go from there. Still trying to figure out why it will occasionally go really rich returning to idle and engine braking.

If it goes super rich, what do your logs say for throttle position and duty? I wonder if fuel pressure is just maxed out and it cannot pull enough fuel since rail pressure is so high. Do run a FPR? I think Audi rail pressure is like 40ish psi.

[viperdsa]

Haven't had time to go through logs and look at throttle position and duty cycle. I don't run a FPR. Turbo shaft speed sensor and gauge went in.

Developed a weird rattle that I noticed tonight. Only happens when the clutch is engaged and any amount of throttle is given. There isn't any vibration with it.

Last I heard was the shop didn’t want info released. First story I heard was head needed work, that was later put to rest but no info on part numbers or anything provided. I believe he’s tuned by UM maybe they’re the ones to speak to. Apparently there’s also a gm/Bosch/Delphi that are similar or the same units. Easiest guarantee is still revlimit in Greece. That or find an injector and figure out how to adapt a harness. I’ve done this already but could not get the maps open to run them.

Here in the UK I see a lot of RS3 injectors with harnesses for EA113 engines but they are only for transverse engines (the harness specifically). My understanding is they burn much cleaner than the RS4s. I don’t know any specific data for the injectors but it seems that they could work well to push for more power.

Rs3 injector discussion.

Hit or miss as far as injector angle, atomization and smoke goes according to this thread.

http://nefariousmotorsports.com/forum/index.php?topic=13752.0title=

[canadianA4B7]

Yes firing angle was some of the data. It was more of an “injector off time” that is what I needed. From what I’ve got they aren’t 100% closing in some cases. The scope images I was shown showed the high point tapering to the off position where, I’d assume this effects the spray pattern. And on others is more of a straight drop off in signal.

Map required KFKSTTHDR

They are said to be about 16% more flow then the RS4 injectors we currently use. This is also dependent on if they’ve been modified. I believe revlimit offers 3 different options and are the same injectors. Something like 550 hp, 650 hp and 748 hp.

[EvolutionArmory]

That's what I have read as well. Changing the maps will usually be required to make them run optimally.

the injectors that flow 12.5% more than the Cobalt SS LNF injectors is 0261500112

that is directly from the company who SELLS this as an upgrade for the LNF platform.

look closely at the watermark on the connector. you can clearly see "112" on the stamp. Outside of the photo from their site ZZP confirmed and another user on here who purchased these from ZZP confirmed the injectors are 112 injectors.

if you ordered and purchased 055 injectors you have the lower flowing of the 2.




and to clarify your LNF vs LDK argument....

The LNF and LDK were produced overlapping 2 production years. LNF block was ditched to save on tooling and it was pushed into the LDK engine. There are multiple part numbers for injectors on the LDK. 1 is the part number for the low output LDK which uses the exact same injector as the cobalt and hhr SS as well as the solstice gxp and sky redline. The 2nd part number is the higher output LDK which has 12.5% more flow and is e85 compatible.




Either way both injectors flow a ton more than stock. The 112 would only be needed in 400+hp applications or for people wanting to run high % of ethanol.

I have 112 injectors on the way from the UK and I will be ordering a 265lph e85 lpfp today.

Hopefully these 2 parts are the missing link to be able to run straight e85 on stock turbo and k04. As long as the HPFP can keep up.




yes but the top of the injectors changed too.

so the only thing I have to know is, if the 055 are big enough for a gt2871r. I have now the stock injectors on my 1.8tsi and they are 16% smaller than these of the 2.0tsi. if the 055 are 30% bigger than these from the 2.0tsi, I think they will be more than enough for about 450 hp.
right?

Did a little digging and found this https://www.golfmk6.com/forums/showthread.php?t=43120&page=29

Going by this, it would seem that the 112 injectors they are talking about would flow 30% more than the S3, if the stock 2.0tsi injectors are the same as the fsi. Per ZZP website the LDK (112) injectors flow 13% more than the LNF (055), and S3 are rated at 13% more than the factory 2.0fsi injectors. They base those 055 and 112 flow rates at 100Bar though, so that may change some things.

Does this seem reasonable, or am I way out in left field?

[canadianA4B7]

I think that your correct. If 30% larger then 1217cc (S3) they’re 1582 cc. The LNF (same flow as newer rs4/rs3) @ 1376 cc. Now the RS4 somewhere I know I’ve read 1091 cc but that’s been corrected to somewhere slightly more then the S3 based on using correct pressure.

I know not a injector thread but any body know if a shop would be willing to take a bit and reshape the tip of the RS4 injectors? I feel like there’s a name for this process I cannot find.

[i3oricua]

Just reread your whole thread. With that code and your car shutting off you should see if you can check your throttle body somehow. It may be sticking open when you come off throttle causing your rich condition since your still getting air rushing in. Maybe if you can get a hold of someone else's to test it. I think you can actually check it through VAGCOM too but I don't know how to do that.

[EvolutionArmory]

Checking throttle body condition is easy. Start the car and go to block 060. The 2 values should always equal 100% when added up. If it equals anything other than 100% something is off.

Just a quick update since it has been a while. PM4 is installed. Got tired of continually waiting for the pagparts lpfp so got the JHM pick your pump kit. Walbro 450 showed up this week and the JHM kit should be here Saturday. Gonna try and get it in Saturday but we'll see.

Did you autoslope your PM4 at 100 Edgar? So that you would be able to have the pump run above 65%

Sent from my moto g(6) play using Audizine mobile app (http://r.tapatalk.com/byo?rid=87676)No. At the end of the day my tuner controller everything through the ECU. At idle my pump is only running in the 30-40% range and then the ECU tells it what it needs to be at during full load. I went back and forth with torqbyte and sent them logs from their software and everything was fine. It definitely frees up the bottle neck at the pump controller. If you measure the LPFP through VCDS it will show in the 60's% but if you measure it through the torqbyte software for a more accurate reading you'll see the pump is operating much lower.

So you're still running the factory config that came preinstalled on the PM4, which is basically just the factory A4 controller settings?

Installed the pump today. I would say about 75% of the install time was fiddling with the fuel line connectors. I didn't quintuple check all my lines with everything attached in the tank and the clearance with the fuel level sensor. So my fuel gauge is currently fubar because there is a line in the way, and didn't find out till I had a full tank and it only read 3/4.

The car feels good. Still had it cut power on me twice at about 5k rpm in second gear. The pump is working, now I'm getting fuel rail pressure too high codes as opposed to pressure too low like I was getting.

Got new gaskets for either side of my water meth plate. Going to pull the throttle body, check it and replace those seals and see if that fixes my rich return to idle or not. If not then I'll start looking harder at it possibly being the throttle body itself. I'll probably try and pull some logs and send them off to Dave and see what he thinks; since it has been 5 months since I last sent him logs.

[EvolutionArmory]

Log 060 and look at the 2 values. They should always equal 100% when added together. If they don’t, there’s something off with your TB.

New phone so I don't get all the notifications like I used to.

To answer your question, I don't remember. There is a file you can download from their site but it would take my car a while to start on that file and then it would not stay running because that file was too lean at startup. I did figure out and understand the software much better after messing with it a lot but Dave is going to have to make the adjustments at the ECU to get you a good running car. Below is an email screenshot when I was talking with torqbyte because I thought I could control more with the software. You could always adjust the slope some to be more aggressive at 5000 rpms to see if that helps solve your issue. Remember to make a backup of your current config so you don't lose that and can go back to that in case you mess the slope up real bad. Plus you can have it up on the left side of the software window (current) and make adjustments on the right and compare the two. If you click on custom setup then you fine tune some of the angle of the slope and at what point you want the pump operating at 100%. I don't know if my pump is at 100% right now, the last time I took a measurement with the software at WOT my pump was only at 92-93% and was meeting the request of the ECU with no problem which I brought up to Dave and torqbyte and they said that it was fine as long as all the fuel requests were being met, which they are.

In the end, your adjustment needs to be made at the ECU and the controller will make sure you have enough amps and allow your LPFP to run efficiently.

At least that's my vague understanding of it all.

No worries, thanks for all the info. Went and watched your PM4 video and for kicks put in all the info for the slope that you had from the RS4 controller to see what it would do. That didn't go well, the car wouldn't idle well so I just changed back to the factory config, which is the same as the one from their site.

A screen shot from the last log that I sent up to Motoza

158484158483

[viperdsa]

Vag-com showed up today so I logged block 060. Didn't see anything more than .4% off from 100%. So it looks like my throttle body is fine, or I just didn't have a long enough log to catch the problem.
Played around with the coupling for the throttle body pipe and put the factory BW EFR dv back on to see if it would change anything. The car ran better with the BW dv vs the Turbosmart one, so it will be staying on.
Got an updated tune from Motoza today. It smoothed some things out and added more injector up top. The car is returning to idle much better, on rare occasion if the rpms are returning to idle quickly it will have richness issues. We'll see over the next couple days as the ecu adapts if it gets better. The car is still only at about 20psi so it still has some growing to do.

[seal66]

Glad to hear the car is running man. If you have question about vagcom hit me up. If your in the Denver/aurora area stop by

[viperdsa]

It's been boost leak ridiculousness lately. Had the hose that goes from the compressor housing to the n75 develop a huge split so replaced that. Car was running poorly after that, so boost leak tested it and the new section of hose that I had put on was leaking; along with 2 other small leaks. Buttoned it up, put about 175 miles on it today, did some 3rd gear pulls and got some logs. Checked for codes when I got home, and have another gross vacuum leak code. So more boost leak testing once it cools off.

[viperdsa]

Pulled some logs today. Here's a 3rd gear boost graph. Pull from 2k-5700rpm, peak boost of 2490mbar at 4400rpm.

Looks good but you should pull to red line, about 6800 or so to get a full measurement.

Do you have a version of the graph with rpm on the x axis? You spool looks slower than I would expect.

[Charles.waite]

Yea flip those axes, hard to look at that and get anything useful.

Edit: actually wait is that pressure in mbar on the left y-axis? Substitute rpms for the time stamp on the x-axis, subtract ambient from the pressure readings (and convert to PSI if you want) then the graph will be awesome.

[i3oricua]

Both of you are so right. I looked at the pretty colors and payed no attention to the axis'

Here’s one of my car from the other day. Turns out my N75 was plumbed wrong (I’m an idiot), but it’s something to compare. That 2500 mbar is actually about 28 psi (MAP is scaled for a 3 bar sensor).

[viperdsa]

Alright did some work on the graph and learning on how to use libreoffice calc. The first one the y-axis was boost in mbar x was just the data point numbers. Did a rough estimation for accounting for atmospheric pressure, was around 7000ft elevation where the logs were pulled so took 779mbar off everything and converted to psi.

I've been thinking about that. Which is why I asked A4 Quattro Joe where is hitting full boost since he is in Denver. The drivability issues have been sorted out in the tune, so hopefully the upcoming revisions from Motoza will be more performance oriented.

[aluthman]

I wonder why yours seems to spool so much slower than mine.

[viperdsa]

It seems to spool slower then every other 7163 I have seen A4 or otherwise lol.

[Charles.waite]

Wastegate sticking open? Or just too loose/not enough preload?

[aluthman]

I’m running 4mm of preload on mine. Might be worth a convo with Motoza about your tune.

[viperdsa]

Should have a new revision by wednesday. I'll see what that holds and go from there. I remember setting crack pressure at about 14psi and I think I have added 1mm preload since, so that should be fine.

i know I'm late, but i'm really just curious what your boost requested vs boost actual looks like.

[aluthman]

Out of curiosity, what spring(s) are you running in your WG actuator? I couldn’t hold boost with the two 7# springs it came with so I’m adding a 5# inner spring for 19# total pressure. Should help with spool and holding boost.

[viperdsa]

Same the 2 7lb springs for 14lb total. I'll be watching your thread to see if it makes much of a difference. I remember Full Race used to have Turbosmart wastegates with like 21lb worth of spring in it, and Geoff from full race would always recommend that one over on the evo forums.

Should hear back from Motoza by the end of the week with a revision and any insight Dave has about the slow spool up.

Requested and actual should be in block 115.

Talked with Dave a little and sounds like the boost curve from my last log looked off. So put a little more preload on the wastegate to see if that was the issue. Here is the 3rd gear actual vs requested.

167036

Might take a little preload back out of it and see if the spike smooths out some. Also just looked at the graph compared to the other one that I posted and it's still coming in later.

[viperdsa]

Not much for updates. Fixed a vacuum leak. Constantly getting high fuel rail pressure and fuel pressure sensor range codes along with power cuts. I think I'll replace the sensor and see if that fixes it. Asked Motoza about the cuts with the last logs I sent in since one happened during one of the pulls. He said that he didn't see anything abnormal in the data that they pull for the tune revisions.

I get the same codes and the same power cuts around 7000 rpm ever since I installed the Golf R intake cam.

Edgar

[viperdsa]

My power cuts have been coming in around 4500-5k when boost starts to pick up. I've had them for a while at varying rpm, even before the lpfp upgrade I would get the high rail pressure code and cuts on occasion. Since things have gotten turned up since then, specially with the last revision, they have been happening more. I wonder if with the 155bar prv the sensor is maxing out and the car is cutting power. I could have swore I saw aluthman mention Ina thread the factory sensor maxes out at 150bar, but the s3 version maxes out at 200bar. Couldn't find that thread today though.

I get misfires if I try to go full throttle at lower rpms but if I ease into then j can get to about 6800-7000 and the power cuts really hard. I haven't changed that sensor and I have the 200 bar one. Just don't know if it will work.

I'm pretty sure the thread you're looking for is free easy fuel upgrade or something.

[EvolutionArmory]

I don’t think you can’t just throw on a 200 bar rail sensor instead of the 150. Call your tuner and ask.

I think things like 200 bar rail sensors and 3 bar MAP sensors need to be scaled to work properly. Call your tuner to verify but I don’t believe you can just put them on without being tuned for them.

[EvolutionArmory]

Are you guys that are getting fuel issues running R cams and HPFP upgrades? It might just be too much when used together.

That’s a good assumption for any sensor in the engine bay. You almost never can just plug it in and expect the ECU to be happy with it. Usually scaling is necessary in some form or another.

[canadianA4B7]

I can confirm Charles comment above. The ECU has a correction factor around +\-20%. Of the device scaling and ECU data are beyond that the ECU can not correct and often puts you in limp mode.

Been working with companies regarding 155 prv and 3 bar rail sensor. Rescaling ECU by a competent tuner cost me $227.52, this is not a full tune only rescaling of sensors that have been changed. And ALL ECU will work with the 3 bar rail sensor if tuned properly.

And lastly the rail sensor and PRV are only required with injectors that can produce enough output. It’s been an expensive week but I’ve paid for very important info.

[i3oricua]

Yea i'm aware I can't just throw that sensor in. I'll let my tuner make that decision for me and tell me if he wants me to do that. He's aware that I have it.

Actually I believe if you have the later VIN split you can throw the S3 sensor in with no problem. I have the VIN split that you can't.

I don't know which VIN the OP has.

[viperdsa]

Well everything has come to a very sudden and abrupt halt. Have been getting a weird noise above 18psi that started a few weeks ago so haven't been driving the car. Was hoping it was something little. Confirmed my fears today, the turbo is cooked. Idk why it only lasted about a year. If there was an install issue which is why it spooled so much slower than every other 7163 I've seen. It's never been over spun, never even saw more than 24psi. Going to get in touch with BorgWarner tomorrow. Everything that I've heard is they don't rebuild these turbos, but I want to see if I can send it in and have them go through it and try to determine why it went out. Don't want to get a new supercore just to have the same thing happen in a year.

Well, Turbo Re-Source looked at the turbo and says that it is all fine and that amount of shaft play is normal for BB turbos.

Well everything is back together. Ended up just going with factory studs again due to delays with the Fastenal test stud I ordered. The broken stud was the weird noise I was getting, it's gone now. Still need to get a socket big enough to do the fuel pressure sensor. Also need look at my control arms and see if that is the source of my clunking when turning the steering wheel.

Pulled some logs yesterday and sent them to Motoza. Hit power cut a couple times at the top of second. It had a little trouble starting today, it didn't hit quite as much boost and it came in a little slower. Parked it for a little bit, afterwords it started fine. Went to get on the highway and it only made 5psi of boost. Pulled codes when I got home and it had a soft P0089 code. Cleared it and we'll see if it comes back tomorrow.

That's just a generic code but one of your fuel sensors might be bad, the one on the rail or the HPFP. VCDS should be able to point you in a better direction.

Shut it down at the store, got back in and everything was back to normal. Made boost and performed like it did prior to this episode. So not really sure how to proceed, if I should go hunting for stuff or just leave it as is for now.

Talked with Motoza yesterday. They could see in the log where the car was pulling power but aren't able to tell why. Everything they saw in the log up to that point looks fine, so they are problem solving. At this point I'm in the same boat as Edgar, H.M.S Occasional Power Cut.

When you get back to CO we should pick a day and take both our cars up there lol

[i3oricua]

Tentative schedule is to ship it at the end of July and it will arrive in Baltimore around 13 August. I'll probably have to fly back out there to pick it up and drive it over to Colorado so I just don't want to hard break it before then.

I'm completely out of ideas with my car. It's up on jack stands anyways while I do some maintenance but I'm curious as to what you find with yours.

Are you using the factory map sensor?

Sent from my ONEPLUS A6013 using Tapatalk

The factory map sensor can’t register anything over 22.5 PSI and supply the right fueling for it anyway unless your tuner has adjusted the scale of it.

You might see more than 22.5 of boost on your gauge but your ECU isn’t seeing it or fueling for it unless the tuner adjusted for it.

what came with your EFR 22 psi boost spring? Or the HIGH boost spring? If your order did not specify the low spring is in the turbo. Not many sellers advertise this as it’s apparently $100 more ordered from EFR, but to change spring yourself it’s 3 screws and a new $29 spring. If you’ve got the low boost I have a spare high boost spring as they were on back order for 6 month in early 2019.

[viperdsa]

I've have a single port Turbosmart wastegate with a 14psi spring setup in it.

Installed some new passenger side upper control arms today and logged block 231. Max lpfp duty cycle was 89.8% and the lowest pressure recorded was 3.7bar at 6400rpm. Hit power cut on every pull I did.

To remove the fuel hardline and drill it out does the intake manifold need to come off?

[aluthman]

Yeah you have to remove intake manifold to remove the line. You could probably drill it in place though and then reverse flush the lines from the hpfp supply hose.

[viperdsa]

No update on tune stuff. Had a really expensive brain lapse this morning trying to pull into the garage and forgetting I had a bike on the roof. Bike is fine, broke the rack, broke the rear windshield, dented the roof rails where the rear of the rack mounted and dented the door. Great way to start a Friday.

Not a 29er. Test rode some when I got this and they just felt weird lol.

Emailed Motoza today and they said that they might have an idea of whats going on, but they need to go through old logs to confirm/deny it.

I am completely stumped on my car. I'll have to wait until after I ship it and arrives in the US before I keep going. It's drivable and still fun I just can't give it everything like I should be able to.

Sent from my ONEPLUS A6013 using TapatalkWell, they sent an updated file. The only thing they said in the notes was 'changes to help with limp mode'. So need to get the rear glass replaced and then upload the file and see how things go. Still haven't gone through the undertaking of pulling the intake manifold and drilling the fuel line.

Pulled the hardline and drilled out the restriction today. Was able to do it without pulling the manifold which was nice. Have driver side upper control arms to do and a slow leak in the driver front tire to sort. Rear glass goes in, in a few weeks.

New glass went in today and was finally able to take the car out. Wasn't able to get a full 3rd gear pull but a wasn't getting the fuel cuts at the top of second anymore. Need to pull some logs and see what everything looks like but if feels better, whether it was the tune, fuel line or both, idk.

[viperdsa]

Broke 3 more exhaust studs, so it's getting a turbo brace. Looking at having the exhaust redone because the old AWE one that is on there is starting to crack in multiple places.

You’re really having bad luck with those. Im on stock studs and haven’t broken any of them in nearly 30k miles without a brace.

I went and looked at your manifold after these broke to see if it was similar. You're using the factory style head flange using the long studs on bottom and the brackets that the manifold just drops into, right? Where as mine is a standard flange that uses the individual studs on bottom to secure it to the head, which is why I think they keep breaking. Hopefully A4 Quattro Joe won't have these same problems since his head flange is similar.

[aluthman]

Ahh, yup. My flange is factory style.

[viperdsa]

Got the turbo pulled. Looks like 2 of the studs that I though broke the nuts just came off. One of the studs is broken flush with the head though. Probably gonna get some Stage 8 locking nuts for the bottom since they keep loosening up and falling off.

No, the head flange on my manifold wasn't designed to work with them.

On a random unrelated note, has anyone heard anything about the iABED FSI oil cooler adapter plate? I haven't found anything and it seems a lot easier than going the 1.8t oil filter housing.

Oil cooler. When I get stuck in bumper to bumper traffic I can watch my oil pressure drop gradually the longer I'm in it. Once I'm clear of it and in fresh air it goes back up. So I think the factory cooler isn't able to keep up, we'll see if this helps.
