The Great Maestro 7 Tuning Suite Thread

[Hansi]

Forget about tuning TVUB based on trims, KRKTE too if you are running large injectors like the ID1000's. Looking at that linearity chart above along with this info, holds the answer why. [;)]

I would not hesitate to teach you everything I know, but it takes alot of time to take in and takes alot of dedication. To really get in the loop you have to eat, breath, sleep Motronic. Even then, you still run into problems you cannot solve without having to disassemble the code, then you will have to start all over again learning something even more complex...

I dont mind sharing info, but just telling one other what numbers to put in which cell, will not teach him WHY that number goes there. You need to learn how everything correlates and which change equal which results, getting the answer without knowing why will just bring up more questions.


Do you have your car up and running now mr. Marius?

I'm guessing cause there's a lot of deviation at lower opening times than 2,5 msec at ~12,5 volts, more at lower voltages?

Yeah, I'm starting to see that it does take a lot of dedication. Sucks, would be fun to learn, but I don't think I have the patience [:)]

Car is running on a base tune, haven't figured this all out, so it isn't being used much nowadays. Saving cash for a custom tune, but I want to change turbo to an EFR 6758 I have laying here before I do that.

You want to focus on the 14v line, as the system voltage when the car is running is around 14v. But yeah, your total pulsewidth at idle will land around 1.6-1.8ms(depending on your idle rpm and torque reserve), thats in the non-linear range or as it is also called "slope". The trims will adapt those ~7% unknowing that the cause is due to operating in the slope.

If you were to increase TVUB by those 7% ala trim-tuning, you would just move up the slope a bit and still be off by like 3% [:)]

See, this is very useful info to me that's never been shared before. Thank you very much [:)]

I guess two better options than increasing TVUB is either to increase idle speed, or increase injection correction 7% at low loads then?

NP [:)]

Just as an example, what I shared now took me easly more than 30hours of trial and error/reading/flashing/logging/calculating to figure out. This is why everyone is so hush hush about just handing out information. You could fully tune a custom setup in 30hrs.

No, the better option is to compensate for the injector non-linearity and still have your desired idle rpm/torque reserve.

[jjvwg]

can anyone tell me what could cause my AFR at idle to get stuck at 10.73 and at off throttle to get stuck at 73.49. 2004 1.8t with bosch 550's. have an experienced maestro tuner helping me tune my car so its not like im going this alone as a noob but he is busy and contact is spotty at the moment. just wanna make sure its ok to drive on till i can get this figured out. I have a small vacuum leak in the brake booster circuit also if that would be of any concern.

[Audiguy1234]

Hi guys I am trying to get through emissions. My problems seem to be fuel system, O2 sensor and O2 heater showing up as not avalaible. I'm in Oregon so I just need the OBD2 to show that they are ready so I don't have issues like people in NJ. Anyways, I set everything to On in maestro. I'm not getting any CEL so that's good and I changed from European lambda to OBD2 mode which shows the O2 sensor. Now I'm still trying to figure out how to get my fuel system and O2 heater to show up. Vagcom doesn't really help much since it shows everything passed.... But my regular OBD2 scanner is showing that I am missing the fuel system and O2 heater.

[daihashi]

O2 heater sounds like a problem with the O2 sensor itself. I'm not sure what yo umean when you say that it shows that you're missing the fuel system.

[Audiguy1234]

The fuel systems shows up as not available. I suppose I could replace the rear O2 and see if it remedies the issue. I'm more concerned about the fuel systems though I have been changing the different modes on maestro and contacted Ctapp but he is still taking awhile to respond.

i just got my maestro 7 suite , but im doing my timing belt and a few other things like gaskets seals ect. upgrades , full exhaust,3'' test pipe 2.5 techtonics down pipe, k04 hybrid, Audi TT 380cc injectors, ECS N75 valve,APR DV valve, APR throttle body hose ,Samco turbo inlet hose ECS fuel pressure regulator gauge carboinio intake system PODI BOOST GAUGE... WHAT KIND OF POWER AM I LOOKING AT MAKING after tuning ?

[Audiguy1234]

I would guess more than what a K04 can make and less than GTRS. Probably 250whp, since it sounds kind of like you are running a frankenturbo.

Oh I thought those hybrids K04 make at least 200whp. 180whp seems like what a chipped k03 would be making. Anyways, does anyone know why the fuel system is unsupported with maestro?

There was someone a while back that had dyno'ed his custom tuned k03 at 200whp, ask him where he got it dyno'ed and go there, then you might hit 250whp on a k04 [:)]

[Audiguy1234]

Hey guys I flashed back to a stage 1 and it looks like all my emissions components and they are now incomplete instead of unavailable. I know this might sound ridiculous but I'm thinking of trying to drive my car to pass emissions since Ctapp hasnt responded for a week. I'm a little confused why stage 1 file allows the emissions to show up but the BT file doesn't.

So has anybody worked out the issue where when going off throttle and then on throttle the requested AFR goes to 11,xx or .80 lambda?

I have searched and read a lot,but can't seem to find a clue as where to look..

Im fueling with the power enrichment,full load is "dissabled", decel and accel fuel are untouched from the basefile,i did try them but got no results whatsoever.

here is a log with the rich request marked in yellow.

I had a similar issue when I had the wrong injector constant set up & it caused them to basically dump fuel. However, that being said, there are a bunch of things that can cause it to dump fuel like that.

One thing I noted while I attmpted to disable the full load map was that it didn't work (set my EGT threshold very high) and it still dropped me into that map. How did you disable that map btw?

My injector constant differs from the calculated value,that's true.. i adjusted it through my fuel trims(i saw this method in the beginning of this thread). my trims are now 2,1 and 1,3.

If i put in the calculated value, the car runs lean and i get massive corrections. So after driving like that for 40 min,i used the trims to adjust. And now im at 0,064xxx(calculated was i believe 0,051xxx)

(3071r, 550cc,stock displacement,though motor was rebuild and don't know if the displacement would be slightly off?,v8 maf,rmr intake,75mm TB)

My EGT threshold is set at 1228 and all the values in the full load map are set at 1,0001.


Yeah, a lot off things could be the cause..i def have to read more,learn more..

Ok gotcha. I initially did mine this way as well but then when I set the EGT threshold very high & put the full load map to .8 across the board just to see if it would drop in there, it did which is why I fell away from this way of doing it. I didn't want to run the risk of it dropping into that map and hitting a lean condition while going at full tilt. I ended up going back to using the full load map to do my modifications at least for now and I made pretty good power that way the last time I hit the dyno so it's probably the path I will continue down.

Im sorry, attention disorder kicked in [:D]

Have you calibrated for the larger TB?

[robbyrr]

np [:)]

Well,i have imported alpha-n and throttle angle vs airflow bins from the 80mmTB basefile, but i thought since i have a maf,the ecu doesn't use these maps(until you get out the range of the maf reading)?
should i tune those maps aswell,even with a maf(V8 maf)?

[robbyrr]

Now that i think about it,throttle angle vs airflow can be traced right?

Watch the kg/hr vs rpm and fill in the tps value from the log?

And then the alpha n should be the same(for a given rpm vs tps the same kg/hr value)?

Or am i waaay off?

[Bische]

Honestly I dont know about the tracing, I dusted off the fault cable yesterday and updated the editor, 32 updates since last time I used it lol.

80mm TB != 75mm TB.

I actually did the R32 75mm TB calibration yesterday. If I have time tonight I can post an export of KFMSNWDK for you.

No,i know,i tried the 70mm and 80 mm when i was mafless but both sucked and even tried calculating the values but wasnt good either..then i got my maf in and it run pretty ok with the 80mm file..but as you can see in my logs i have several issues still...and im learning as i go.

So i was wrong in assuming when using a maf , KFMSNWDK and KLAF are not being used..? Good to know.[:)]

i have the ecs n75 and i have a MBC brand new in the box just gotta hook it up but im boosting 19psi now its quicker but not where it should be. no check engine iduls amazing but i know it should be faster a friend of mine has the b5 wagen sport with a shot clutch and he pulled 2 cars in front of me. i feel i loss power around 5 thousand rpm in 3rd its weird

PS
Has anyone put in the ecs fuel gauge that goes on your fuel line with "special hose clamps"?

Why run the n75r if you have maestro? Seems it'd be much more of a hassle to tune.

[MmmBoost]

Because you get better boost control at part throttle. Manual boost controllers and EBC's pretty much give you on/off boost control. Not so bad if you're only running 15 PSI......but I run 30 PSI.

Hello again
i got into my car and i didnt have any boost.. well for the first few minutes i did then it went down and creeped up slow to 10 lbs not the 18 psi i have it set at with my eurodyne tune anyone ever had this happen what can, cause this?

[Audiguy1234]

Managed to pass emissions with CTapp's updated file. Only small issue was SAI was unready and i probably would have thrown a CEL had I drove more miles. I used vag com to set readiness for the others 5 mins before testing and I had an eBay L O2 spacer with a HFC. I pretty much have all my emissions stuff except the sai.

I 100% agree with you Chris, his post said ECS N75 so I assumed he is talking about an N75R.

[MmmBoost]

You would need to tune ANY of the boost control maps anyway. The only way you could leave it untouched (in theory) is if you were running a K03 and the stock N75.

I figured that would be the case, but he stated he is still running the base maps which I'm guessing would be calibrated to the OEM n75. You know immensely more on this subject than I do, and I am going on with the assumption that his n75 isn't stock. Either way, its pretty clear he needs to do a lot more reading on maestro tuning.

[Bische]

WTF, the N75 boost control uses a PID algorithm to determine the duty cycle.

If you dont have a good understanding how a PID controller works or want to learn it, you will never get the boost control right.

[robbyrr]

Does anyone know what other maps share the RPM axis of Target Filling(KFMIRL),if any? in maestro first row is 4 rpm..seems wierd to me,and i rather have the rpm values the same like optimum engine torgue(KFMIOP)

[ddillenger]

Do any of you guys have the TVUB (voltage offsets) you used for the genesis 415cc injectors@4bar? Or just the datasheet? Information on these things is rare.

Hey guys
Audi a4 q1.8tq b6
i havee the complete k04 upgrade tt225 injectors 3inch test pipe apr dv valve new plumbing from audi tuned on the AMB K04 TT225 file
i lowered the boosted down to 17psi the car was runninng amazing then i noticed a slit oil leak from my cam seal so i fixed it and now the boost is cut off i check for boost leaks but everythings seems fine but no boost any one have this problem be 4? could my n75 from ecs be messed up??

[cruzanstx]

Ok guys I drive a 2002 tt AMU with wideband conversion with the 870cc mafless tune on an AWP ecu with gt3076r with rods. I am running the base file from library with the only mods being to the BVC and IC using the STFT and LTFT. My block 32 is showing -6.0 and 1.6 in the STFT and LTFT.

Using truboost EBC, not n75. not sure if this is my issue saw some post about "how to boost past 20psi on n75" but im not using it so wtf.

My issue is that for some reason I am consistently dropping boost/throttle slamming/limp moding at 20.5 psi. I took 2 logs of the situation and only thing that my noob eyes can see is wrong is that my timing is high, but Im not having any timing pull.

Can someone take a look? Thanks in advance.

Also does anyone know if the a6 maf has a similar profile to the v8 s4 maf or will it need to be scaled?

[canadianA4B7]

was just forwarded this thread now that ive got maestro myself. finally got the BT A4 tuned with base file and the car is amazing and fast as ever now.

question though ive got 2 cars the 2007 A4 and I also own a 2001 allroad w 2.7T APB engine. now that I have maestro can I load files onto the allroad aswell? or do I need to pay them for a second file or something? anyone know if this is a possibility or have a base file for a 2.7T running a S4 engine, K03's larger inlet pipes from 034, 2.5" exhaust no cats (but cats will be going in for emissions next april), synapse DV's. nothing to crazy needs to be done just want to get a bit more boost since ive fed and exhausted much more air then OEM.

thanx for the help in advance.

So, to answer an old question of mine re: how much air the V8 S4 MAF will measure on the default Maestro values, the answer is about 500CHP (found a google docs spreadsheet made by Bananas (IIRC) on the Maestro website)

That is not correct, it can read 1800kg/hr which = 650chp on average.

The b5s4 sensor is maxing out at ~500chp.

[rogerius]

What are the consequences of disabling the Torque Control, on BT MAFless non n75 base file? Is it bad for the driveability or the engine? Will it knock beyond control? Why is it set as a toggle in Maestro?

[ZimbutheMonkey]

The b5s4 sensor is maxing out at ~500chp.

If you eliminate the offset values that Tapp put into the base 630CC file it will. However as I was saying, it appears as though Tapp put in a set of offset values that max out at around 500 CHP on the BASE 630CC file.

Here's the link I used for the spreadsheet: http://spreadsheets.google.com/ccc?key=0AnU1jYuC-fFrdERMSnJ5SkJkMndOOGh5eGZORGdnNXc&hl=en

You lost me with Tapp stuff, the numbers I posted are accurate and includes the backflow offsets.

[ZimbutheMonkey]

You lost me with Tapp stuff, the numbers I posted are accurate and includes the backflow offsets.

If I understand it correctly, it looks like Tapp scaled the MAF values to give better resolution within the flow ratings for the turbo that the 630 file was written for. IIRC, it was a 3071, so an upper limit of 500 CHP seems reasonable. It makes some sense as to why he would do that. There's no sense in stretching the MAF readings out to 650 CHP and loosing resolution if the turbo isn't going to flow that much.

Like I said, check the spreadsheet link that I posted and see for yourself. Maybe I misunderstood the posted values, if you could clarify I'm certainly open to being corrected on the matter. I would rather have good info out there then insist that I'm right if I'm mistaken.

[rogerius]

I accidentally logged for ignition retard in light city traffic and I noticed quite large CFs, 6-11* at light throttle tip in, always below 2400rpm. If I step harder on the gas pedal or if I go WOT, these CFs drop instantly to "0" and eventually at WOT I will record max 3* at redline.

So, has anybody noticed CFs in very low rpm, very light throttle driving?
Is this normal?
If not, what would you do if in my shoes?

Would really appreciate any insight!

Just flashed maestro for the first time and I cant even get my car to start. I was running the Uni 630cc tune before and had no problems. I upgraed to 1000cc EV14's in conjunction with Maestro. FLashed the AWP Stage 3 EV14 file and plugged in my own KRKTE that I found using the info in this thread. Car turns over and fires a few times before dying. Aweful back firing as well. I cant really get any data out of the logger since the car wont fire up. The injectors are good, I ohmed them out. What in the tune could cause this? What should I scale to get it to start? IC? BVC?

BVC?



Oh Car is AWM:

034 AFPR set at 3bar
034 Fuel rail

If I understand it correctly, it looks like Tapp scaled the MAF values to give better resolution within the flow ratings for the turbo that the 630 file was written for. IIRC, it was a 3071, so an upper limit of 500 CHP seems reasonable. It makes some sense as to why he would do that. There's no sense in stretching the MAF readings out to 650 CHP and loosing resolution if the turbo isn't going to flow that much.

Like I said, check the spreadsheet link that I posted and see for yourself. Maybe I misunderstood the posted values, if you could clarify I'm certainly open to being corrected on the matter. I would rather have good info out there then insist that I'm right if I'm mistaken.

This doesnt make any sense to me

Alright the car finally started with a file given to be my by a buddy. Only problem is that I have to hold the throttle down a bit to get it to fire up. Then it idles horribly at about 900 and then starts hunting and surging. If I hold the throttle at 1200-1500 it runs great. Once it's warm though the car fires up and idle great first time. So cold start is a huge issue. Any suggestions?

[Dolphin18T]

I keep failing emissions because of high NOx levels. I'm thinking about creating a 'valet' file by basically dumping a lot of timing. Anyone else have any ideas for lowering NOx? Run richer?

what should the car realistically put down? engine is healthy, and whats "safe boost" before doing rods.

[TheOperation]

Anyone know why my AFR Request will not follow the values that I have set in my power enrichment map ? I have tried setting my EGT threshold for Full load lambda quite high so that it doesn't engage during a single gear pull, even so my requested AFR isn't even near what I have it set to in my power enrichment map. I would prefer to use power enrichment, to full load lambda because it seems as though I get much higher timing advance with less CF's when I do utilize that map.

You set requested boost via the Max VE table, and you meet it using the boost duty table.

[jayiszraw]

You set requested boost via the Max VE table, and you meet it using the boost duty table.

Thanks a lot! but what exactly do you mean by meeting it with the duty table?

[Bische]

The Boost duty table is I component upper limit in the boost control PID controller.

It is the steady state N75 duty cycle needed, to produce X boost at Y RPM.

I was just wondering if it's possible to use ME7 to tune out the readiness checks so they all pass and allow the car to get through emissions?

[Audiguy1234]

Not possible. You can however remove CEL codes by changing the fault class to 0.

[jayiszraw]

Not possible. You can however remove CEL codes by changing the fault class to 0.

so this being said what exactly happens when switching diagnostics on and off.

[Audiguy1234]

When you turn off the emissions, it causes the ECU to ready not ready. This means you will fail your test.

[jayiszraw]

any formula to dial in consumption gauge constant?

[ZimbutheMonkey]

Just wanted to toss this retrospective comment in.

I used Maestro to tune my AEB BT setup and although it was the best gang for my buck, it has it's limitations, lack if customer support being one of the big ones.

If i was to do it over with slightly deeper pockets, , i would have looked into one of the new AEM infinity standalones.

Unreal processing power, extremely expandable, VE based tuning AND customer support to help you use their product.

Plus, it works extremely well with unique builds (ie a 2.1 liter conversion ). Only downside is that there aren't any plug and play harnesses. However AEM does sell universal ones to get you started.

Anyway, just my 2c having gone thru the process.

[jayiszraw]

no need formula!
"consumption gauge constant" is equal to the cc/min your injectors are rated for at 3 bar. (630 if you run Siemens Deka 60lbs or 630cc/min@3bar)

I'm super new to this and trying to learn as much as I possibly can but kinda getting overload brain cells. I attached a video of my car running but the main issue is that I cannot boost past 2psi. I checked the n75/wastegate lines and all seems well. I'm not showing any fault codes either.

Make some logs. Requested vs actual and n75 duty cycle will be helpful.

Check for boost leaks. Did you change the n75 and possibly install it incorrectly ? You can also disconnect the n75 and connect the wastegate directly to compressor housing and see if you're able to boost, with that configuration max boost should be whatever your wastegate spring is set to.

Logging is done through the flash program not maestro. Connect your dongle/cable to odb2 port (whatever its called) and turn your car on. Go to logs in there somewhere. You'll need to know what measuring blocks are and which to log for certain things.

Its been a while since I've used it. I'll try to boot up my laptop this weekend and see if I can give better instructions

I'm in the same boat and I agree with your feelings.
I bought a car with Maestro and most threads out there are discussing specific items etc. with people being way ahead of my knowledge of ECUs and turbocharged cars. I wish there was a manual too. The best start I found was this thread on VWVortex: http://forums.fourtitude.com/showthread.php?4613781-Maestro-7-Tuning-FAQ-DIY-hard-data-and-advice-thread.

Beyond that, most of the advice is "just to log". But like you, I had spend many hours figuring out "what" to log, why to log it, and how to log it and then interpret results. There's no easy handbook. I even emailed Eurodyne, they just referred me to a local tuner since they just sell the software/cable. Lovely.
I understand that this is advanced software with great potential benefits and risks. But everyone has to start somewhere and I'm still looking for that basic "somewhere". Linking to a 200-page thread (like I just did!) feels very overwhelming.

Hello, I am new to the forum and new to this 2002 Audi A4 1.8T manual transmission. I have EuroDyne tuning suite for the car and just looking for some information on tuning.

I am new to the EuroDyne tuning suite as well. Well I have reading a lot of forum by just searching EuroDyne tuning guide. Several good threads came up that helped me understand the software.

So my specific question I am looking for, is what table controls the desired lambda? I see only two tables that really offer a target lambda and those are the Power Enrichment and the Full Load Lambda. I am looking for what table is telling me specific car right now at idle to run 1.11 lambda.

[SleeperAvant]

There should be an idle AFR map there IIRC.

If you convert your 1.11 Lambda it ends up being roughly 16.32 AFR, so it's a tad lean.

I would target anywhere from 1.00 to 1.03 Lambda for your idle.

Refer to this table: http://www.tatech.fi/cms/uploads/file/Lambda_vs_AFR.pdf

Thank you very much for the response.

But there is not a idle AFR map in my file, I even pulled a couple of the files from the "select base file" tab. No idle AFR map in those files either. In less, I am just completely missing something.

But as for the target set point, that was my plan to target 1.00 lambda.

But that's my issue, not sure where the table is or if there even is one. I need to correct the idle and part throttle commanded lambda, cause fuel corrections are pretty close to the commanded.

If you find out any more information, definitely let me know here.

Thank you very much.

I confirmed it is full load lambda map. I shared a file with you.

You may want to check your other parameters or hardware that would be giving you a lean condition.

[Bische]

It should never target leaner than lambda = 1

Did it do that from day one?

[MarkTucker]

I got your full load lambda map that you pm'd to me. Your's is almost the exact same as mine is already. It is set to 1.0001 in all the low rpm/ low load % ranges.

But what I did also try, I lowered the EGT threshold for full load lambda table. I actually set it as low as it would let me. Currently at .097015 for the EGT threshold for full load lambda. So it should be commanding the desire 1.0001 that I have set in the full load lambda table. Its not tho, still at 1.11 desired lambda. I even let the car warm all the way up after flashing that in, to make sure that it just wasn't stuck on that while in the first startup of being in open loop. But went into closed loop fine, o2 corrections started working, and got my actual lambda pretty close to the desired lambda of 1.11 again.

Thank you very much for all the help.

So in short, is it fixed? Or is it still targeting 1.11 Lambda?

[MarkTucker]

So in short, is it fixed? Or is it still targeting 1.11 Lambda?

Sorry, no still targeting 1.11 lambda. Sorry, I didn't really make that clear.

But kinda least of my worries now at the moment, because I actually bricked my ECU now. I flashed one of the base files from the EuroDyne "select base file" tab. And now no communication to ECU.

Comes to find out, the ECU that is on my car is from a 2004. The VIN # does not match my car. So I called up EuroDyne and asked for some technical help, and from the help they provided over the phone and me doing the list of things to try. We discovered the ECU is now bricked. Never would have knew that it was a 2004 ECU, cause I bought it that way.

So now searching for a 2002 ECU, then to pick up where I left off.

Thank you all very much for all the information you have provided.

If you're up for a real tune, hit me up. Crazy wait time atm unfortunatly though..

[MarkTucker]

Alright guys, I finally got a 2002 ECU for manual transmission. It was hard for me to find a used one.

Installed it in the car and it actually started up, ran really bad. But only started it to see if it would actually start. So it did.

I sent the old ECU to Eurodyne, explained exactly everything I did, and just did not know that it was a 2004 ECU that was installed into my 2002 car. So very awesome of them, the sent me the license to license my new to me (used) ECU.

So I just flashed the license file into the ECU. To keep this from happening again, I want to make sure I start with the correct file. Should I start by doing the following -

open EurodyneFlash, click here to start, (for powertap flash tool users) Flash my engine ECU with software from Eurodyne server, and select the stage II tune file. Then read the file once flashed and beginning editing that file with Maestro?

Or the following -

Open Maestro, select base file, open AMB_2002Model_Stage2_371cc.mstro then go ahead and start editing inside of Maestro, then flash using EurodyneFlash, click here to start, (for Maestro users) Flash my ECU from a file?

Just figured using Stage II file would be better than starting from stock. Opinions on that as well please?

I am just wanting to go about this the correct way, so I do not have to go through this again. It definitely sucked.

Thank you all for any advice.

[MarkTucker]

My next question,

When I go into Maestro and open one of the select base files, I have 3 options for 2002 AMB.
- AMB_2002Model_630.mstro
- AMB_2002Model_Stage1.mstro
- AMB_2002Model_Stage2_371cc.mstro

When file should I use as my base file? Is the AMB_2002Model_630.mstro like a stage 3 file?
It has a high boost limit and a couple more available tables. Example: Stage1 & Stage2 have Timing map, cam position 1 & Timing map, cam position 2. 630 file has Pump gas timing map & Race gas timing map, does not have position 1 & 2 map.
Also, 630 file has more tables under fueling & idle. Which look to very helpful, I just want to make sure. I use the correct file.

Do not want to brick this ECU. So I am trying to be very cautious until I completely understand.

I have found out alot more about the car tho. It has been rebuilt, upgraded rods and pistons(I believe previous owner said Wiseco Pistons). Upgrade camshafts and valvesprings(still trying to find out brand and part numbers). AEB cylinder head that has been ported. Custom intake manifold. Custom intercooler system. Custom exhaust header. T4 60-1 Turbo with .81 AR. Manual boost controller(I currently have it completely open, so it only runs wastegate spring pressure, which I am not even sure what that is yet). Chrysler Throttle Body # 04861691AA. I installed a set of Injector Dynamic 1000's injectors.

Thank you all for any advice.

If so what is that donor car/injector size.

Audi TT 225 injectors will take you as high as the MAP limit on the K03. If you don't want to screw with used injectors, my buddy with a GT28 B5 on Maestro likes the 550cc Injector Dynamics.

As far as the DV goes, I'm partial to Forge. Lube it every other oil change and it will work great. I've got the 007 on both my Audi and VW.

This is B8 related but getting an answer about maestro on the B8 is impossible. I bought the 799.99 powertap, and tuning suite and I have been running the stage 2 tune from eurodyne. I went to go do some edits to the "base files" that you pull from the server, and I only get a very limited selection of editable maps on the side menu. Is this normal? I also wanted to make some changes to ignition timing and smooth these maps out a bit, but I only have access to two tables for cam position sensitive timing. Has anyone done any editing of these tables to help improve ignition timing progression.

[BARRY]

over time Eurodyne for the B6 A4 released more maps to the tuning suite. that maybe the case for the B8, but as with all things Eurodyne we're constantly left in the dark.

[Bische]

Those two maps are weighed by the current intake cam position. Intake fully retarded = map1, intake cam fully advanced = map2

I assume the current cam angle is logged with the suite, otherwise the Maestro suite just fell down yet another pinhole in my book lol

I was playing around with Eurodynes Stage 1 map and am absolutely clueless why the ECU is pulling timing from the minimum timing map. All other maps even with adjustments do not equal actual timing. Does anybody have any ideas? I stopped there...I think it is because with the settings I made, the engine is idling pretty high, as I do notice the throttle position fluctuating. Assume that the ECU is trying to drop the idle speed using timing?

I have a bit of trial and error to complete. I thought %Torque could be pin point accuracy, but no as the ECU is trying to stabilize the %Torque does move all around the map. Correct me if I'm wrong.

Why would you want to disable lambda control? [confused]

[BARRY]

because my STFT are all over the place. i'm seeing +10-12% at some points of idle, +8-10% at some points in the mid range, and -5-8% in other parts of the mid range. my LTFT's 95% of the time have no values.

The ECU is doing a lot of work to correct. I'm not used to having so much ECU correction as when I tune standalones I have no deviation, so much that I generally use no O2 feedback at all. Only use O2 for display and not correction.

Basically I want to bring my correction maps inline as so the ECU does as little correction as possible.


UPDATE:
I've been informed by Eurodyne that you cannot disable O2 Regulation. In that case I'll just have to proceed with corrections like everybody else.

[Gin+]

I've read that unplugging the n80 makes the ecu show STFT corrections but doesn't actually apply them.

[BARRY]

that's a lie...at least for the B6 it is. since block 99 cell 4 states O2 Reg-ON, then STFT's are in use. along with that my monitoring over the past few days has shown that all STFT corrections has directly impacted "actual lambda" to bring it in line with "target lambda" hence why I asked how to disable O2 Regulation.

the problem is, Eurodyne hasn't put any documentation together for anything. no platform specific information, no help guides, NOTHING. then when you email them with a question they give you short brief answers. when you reply with more questions, they seem to probably think to themselves this person is an idiot then they don't respond.

well if your dumbasses put together a fuking help guide like ANY OTHER programmable computer you wouldn't be badgered with basic questions that seem to annoy you.

Go to Nefmoto.com, whatever your question is, there are people there who can answer it. As helpful as the AZ members are, you won't find answers around here for Motronic tuning.

Just make sure that you do some searching before posting your question. As well, posting .csv logs from your car will also quicken the response time as well as the quality of the advice. It's kind of maddening when someone posts a question about a dynamic process like fueling without any meaningful information as to what the car is actually doing.

In terms of posting logs, forget Eurodyne, download their ME7Logger software and configure it. It will allow you to log 25-40 or more variables at over 15-30 samples a second. It kicks the living shit out of any other software available for ME7.

As well, you may just want to consider saying fuck Eurodyne altogether and just tune your ECU yourself. There are a number of DAMOS files posted for the 1.8T, you can just ID your Eurodyne map areas and port the values over into Tunerpro or WinOLS and then you're not limited to what I see as a half-assed tuning tool...

Trust me, once you learn how to tune Motronic yourself, you stand to save a ton of money in the end by not having to pay some tuner $800 every time you do a build.

Hell, so far I've written files for my B6 S4, B6 3.0 V6, stage 1 1.8T and stage 3 1.8T. That's well over $2000 I would have had to pay otherwise (that said, it took me over 2000 hours to figure it all out so maybe I'm not so smart lol [:p])

[BARRY]

[up] ya, thanks a lot for the info. i kind of was in a situation where i purchased Maestro many years ago before NefMoto had anything more than ECU reading software and was trying to build a ECU database.

I have done quite a bit of reading on NefMoto and have learned quite a bit about the Motronic ECU from that site. Definitely a great resource. You'd think that with free options out there, the boys at Eurodyne would try to step up their game and support, but nope, who knows what they're doing over there. Every week it seems I have to download a new version of the software with no change log and no added features. Such a waste of time.

I know, I was in the same situation, years ago when I got it for my AEB.

Also agree with your assessment of Eurodyne's completely nonexistent customer service and useless updates. I can recall numerous times (before my phone could be a wi-fi hotspot) when I was out in the boonies dialing in my tune, going to activate the software and getting shut down because I hadn't updated it.

To be honest, I'm trying to figure out if Chris Tapp is even trying to sell this system anymore. It seems as though he's pretty much stopped developing it and now he's just coasting on auto-pilot, trying to drag out as many remaining sales as he can.

My only question is; what IS Tapp doing nowadays? He had a really good lock on the market with this system and I'm sure that it took a lot of time to develop, but it seems almost as though he just lost interest and is now letting it languish.

And it's not just Eurodyne users who are getting the snub. A good buddy of mine, who actually helped Tapp develop the 1000CC AEB file says that he can hardly get an answer out of Tapp as of late.

So yeah, I dunno.....

[BARRY]

they only answer questions that can be answered in short responses. as far as development I feel that since our product has been released they no longer care. they're continuing to introduce Maestro for new platforms but past platforms get the snuff.

[ZimbutheMonkey]

Which new platforms have gotten Maestro?

Nothing for MED17, Nothing for Simios8+ All they have are stage 1 flashes for the MED 17 ECU's.

As well, they haven't expanded their offerings for Porsche either past ME 7.8

ya, well either case...it seems once a platform has been released to the public you're off to fend for yourselves.

you'd think they'd try to integrate new features that are available from newer platforms. i mean he's rewriting code. oh well whatever. hopefully anybody in the market looks through these last few posts and makes a judgement call for themselves.

You're correct, my bad. the 8K2907115 series are MED17.1

Lord what a shitty map set though....

Seriously, 20,000 maps and THAT's all he includes for editable content!!!???

Sub'd and yeah, tapp did a pretty piss poor job with the MED17 maps. My A5 2.0t was seeing AFRs in the 10s on the stage 2 base file. Its like he wasn't even trying.

Resurrecting this thread from the grave..

I'm looking at tuning options for my B6 1.8T with a T3/T4 50 trim turbo build coming up. I emailed Eurodyne support today asking them if they have any base files for the T3/T4 for the 1.8T for Maestro 7 and they said no. And that they don't offer custom base files.. I was very confused since I've been searching T3/T4 builds on VWVortex and AZ and have come across multiple people running this turbo with Maestro on the 1.8T, and it seem likes the tuning process is to start with a base file provided by Tapp and then tune it your self from there. Maybe I spoke to the wrong department @ Eurodyne? and maybe I need to talk to this Tapp gentlemen?

Any help/suggestions would be greatly appreciated!

[BARRY]

Eurodyne does not offer base files. They do, but not for everything. You basically have to start with a base file which could be a simple stock file then modify your injection constant to your injector. From there you'll need to complete datalogs while driving and then make adjustments to your maps a little at a time.

The Bosch Motronic ME7 ECU is very different in map configuration than many other ECU's.

http://nefariousmotorsports.com/ is a better place for tuning related answers as they have access to the "same" maps as Maestro plus many more.

[Corrado_Guy]

They don't make tunes specific to your setup, they make tunes for your ECM and you customize it yourself. When tuning you have a few choices, you pay someone to do it for you, you use Maestro which allows you to tweak with it, or you learn how the ECM works and tune it yourself. Those are listed in order of ease but you could go with any of them and have success. I went with Maestro because I really didn't want to go through the time to research and learn about ME7.5 when Maestro covered most of my needs.

You get a base map with Maestro and you setup your injectors and then start logging and tweaking it until you get it right. There are no off the shelf tunes that will work perfectly with your car any other although they may be close so to get it right you either pay someone, do it yourself, or get something that is close. I have a BT setup and used their base tune and with some tweaking got it right by my logs and has been working well for 4 - 5 years.

is the single most useful thing i've ever found. honestly not even sure why people aren't directing people to this as it explains almost ALL questions asked in many many threads.

[Moes]

Thanks for the info Barry & Corrado_Guy

So when both of you say you get a base file/map with Maestro 7, you mean a base file for the ECM that would work for any turbo? (You would need to input all the tables yourself?) or does it already have all the tables pre-populated?

I was hoping I could use a file for like a GT2871 or GT3071 as start and then edit it with 750 or 630 injectors for a 1.8T to start and update the injector tables and fueling/ignition tables to suit the different airflow/power band characteristics of a T3/T4 before attempting starting the engine.

I’m going to read through the links you provided tonight, looks like lots of good info.

[Jezza]

The tables are pre-populated, and will work for any turbo. They will just need to be tweaked for your particular turbo. If you already know what the values in the tables are and you know the capabilities of your turbo, then you should be able to get the tune pretty close before ever flashing the car. You might be able to get the table values from someone else who has a similar setup to yours. That would require even less tweaking (maybe none) than the base file.

[Corrado_Guy]

When you setup your Maestro tune you get access to a lot of different base maps which have the settings for many different setups. My engine is a ATW with an AWM swap (all stock ATW wiring and sensors and a Raceline harness for the pri O2) with a AWP tune. When you select your base tune you will want to get one with the closest injector size and MAF size and you are good.

[BARRY]

select the base file that is correct for your computer. if you load a map from one computer model to another you can brick your ECU. be careful when doing so and confirm what you are doing is ok.

[raudi_s4]

Anyone running a B8 s4 maestro tuned? I just purchased it, and have a 187 mm crank pulley I want to tune for..I thought there would at least be some base files to play with, but it tells me there are no base files for this platform yet. Just the stage 1.5 (91 and 93 octane) stage two single pulley and two dual pulley tunes(91 octane and 93 octane) again. So three tunes, just two different octanes.

Well just got my maestro and pushed into stage two with my mods. I’ll have to go through a lot of reading here for tuning, adjustments and ideas. Lol!! Def where I want to be !!! Thumbs up for all the info peeps !!!

[BARRY]

feel free to ask. i'm only a novice since i'm also just a stage 2 with maestro. i am doing all my learning on the setup before i go big turbo and 2.0L.

[B7_4_JG]

So there a thread here where I can ready about how to tune with maestro. I’m pretty sure there’s got to be a lot of people that have already tried many things with since it’s not a new thing, if anyone can point me into the right direction it would be great. I have a FMIC, intake system, and test pipe. I’ve already done all mayor tune ups to my car and got my suspension all set. For now. A few more tweaks to other parts but I want o start getting some power out of it. Taking it slowly to enjoy it. LOL

Hi All,

Bringing this back in the hope someone can check my Injector constant math?
It seems a bit low to me. [confused]

I have some Injector Dynamics ID1050x on the way, which are 1065cc @ 43.5 psi

my displacement is 1.825 due to 82mm pistons.


1065xsqrt(58/43.5) = 1229.75607337

KRKTE = 50.2424*(1.825/4)/1229.7560 = 0.01864778053

Is this right?

Edit: I'm missing the conversion from cc/min to g/min aren't I....so

1229.7560 x 0.684 = 841.1531

KRKTE = 50.2424*(1.825/4)/841.1531 = 0.02725198896

That seems better..
Is anyone running some ID1050x with Eurodyne?
Just wondering how close their BVC values supplied by Injector Dynamics were?

Grams to cc should be 1:1 IIRC especially when dealing with fluids.

A ME7 KRKTE life hack: Divide your stock injector CC with new injector CC, multiply your stock injector KRKTE with that number - gets you very close with alot less headache[up]

Edit: These numbers are just off my head,

272 / 1050 = *0,259047619047619‬

0.1035 x *0,259047619047619‬ = *0,0268114285714286‬

But then stock base pressure is 58psi, so you need to additionally divide stock KRKTE number for the difference in base pressure before you apply the above - if running your new 1050'[email protected] instead of 58psi base [up]

[00black1.8t]

How many people have scaled their maps to extend to 8000 rpm for built heads? Wondering if its needed or if it just runs the closest cell?

[BARRY]

i've rescaled my maps before, but not for high rpm. eventually went back to stock RPM scaling. as far as if you haven't, it'll utilize the closest cell.

[00black1.8t]

Good to know. I figured that was the case. Not gonna gain a whole lot tuning 7000-8000 rpm so not worth it I guess for a street car. My concern was timing/fuel maps if they fell off. But I guess if I examined a log it would show in the tracing where the data came from.

Hey guys, never really post but I need some guidance. I've been at this for a while I have had this software for a long time hut never have gotten it to work. I've just gotten upset and given up multiple time. I had another ECU tuned for my ko4 swapped 1.8t so it was never a huge deal just a serious chunk of change spent for software I never use. Recently my ECU got wet and it was a busted ECU cover to blame. Since fixed it but need to flash my original and licensed ecu so I can drive my car again. Long story short here, the ECU I dont believe is bricked because it will communicate with the maestro software. I just cannot for the life of me get the ko4 base tune to flash to my ECU. I've included a picture of the error response I get from the software. Can anyone tell me or point me in the right direction to get this ECU flashed? Any help will be greatly appreciated, at this point at my a loss and I really dont want to go buy another ECU with a flash file pre loaded. Internet gurus I'm calling for help. [headbang]
