Some exciting news to share.
Tapp emailed me this morning informing me that V2.0.9 now includes the switch to control whether or not you're using a returnless or a return fuel system. I asked for this a few weeks ago and he delivered this week as promised. I'm quite happy about this.
SO.....

"should" do the trick. I haven't tried it yet.....so I can't confirm
If it does what it is supposed to, that is pretty fantastic. Unless the "base map" is built ignoring the manifold correction table...in which case, oh well.

Could you clarify?
My thoughts were more for modifying the tunes provided:if swapping between returnless and return fueling was a simple as flipping the switch you outlined, that's awesome. The catch is if the switch was added after the fact- meaning that the original fueling tables were written taking into account the returnless fueling (easy enough to check- does duty cycle go up artificially with load?).
In other words- are the fueling maps modified by the switch all the time or does flipping the switch simply enable "injector correction for manifold pressure" map which then modifies the fueling maps. If that is the case, you'll have to rework the original fueling tables anyway.....
I hope that makes sense....probably not.

Can you ask Tapp to open up the transmission control unit maps for the tiptronic? Particularly, to change the shifts points so it doesn't upshift when it hits the stock redline, ~6500rpm (I want to be able to bump this number up).
I asked him before, but he said I was the only one to ever ask for it, and didn't see a demand.
Any other Maestro 7 tiptronic owners out there?
I will be soon. As scary as that sounds to me.

there are no traditional "fueling maps" in Motronic 7+
The switch has to do with how the ECU calculates injection pulse width based on fuel pressure.
When the switch is set to "0", it tells the ECU to that the fuel pressure is referenced to the intake manifold pressure in an initial calculation that is then compared to ambient pressure. When the switch is set to "1", it tells the ECU that the fuel pressure does not reference the manifold pressure and to use a value of 1 atmosphere (1013 kpa) instead in this initial calculation.
.....these calculations then go into the table posted above which compensates injection pulse based the delta of fuel pressure between system pressure and the result of the referenced/non-referenced calculation described above.
The "ON" position in Maestro sets the bit to 1, "OFF" sets the bit to 0.

So ALL fueling is a sum total of varied tables? There is no base map (effectively a VE table)? Crazy Germans...

Chris. I have the Injection Correction for Manifold Pressure table, but I do not have a "on/off" selection.... whenever you turn it "off" does it set the table to 1.000, like your table is showing?
If so, do you think I could just do that?
fuck I hate having a 02.

So I feel I'm entitled to ask a question after reading all 7 pages, and being able to understand about 35-40% of what I read. I see a lot of people here complain about having an 02. Why is that? Is there more built in to an 03 ECU, as opposed to an 02? I'm very interested in going with maestro 7, with eurodyne at the very least, but I have an 01 awm a4. Am I barking up the wrong tree, is there going to be things that I would be limeted to based on my ECU?

Now before I ask for suggestions, let me also tell you that I am running a used ecm that I believe to be from an automatic transmission TIP B6 A4, but the model number of the current ecm matches my stock ecm.
I think it is something I can resolve with vag-com, but I'm not well versed with it and wanted to be more educated before i started tinkering.

When you have the eurodyneflash open and you get that error, unplug the the usb end of the cable, wait a few seconds then plug the cable back into the computer and try to connect again.

Wouldn't "remote tuning" be great? If in need, Eurodyne can help you with some tweaking of your file. I'm kinda surprised Eurodyne hasn't offered it..
Suggestion for "remote tuning":
Log your car while doing the following: xx minutes partial throttle slow driving, x minutes idling... Send the logs and the file used to provide the logs to us, we will give you 2 revisions for $100. Fine tune on dyno available if requested.
Something like that.

I just updated my Maestro...wow...lots of new things.
I am still not understanding why i have a Log Viewer V5 and Log Viewer V3
V3 shows me 3 tabs
and the V5 only shows the chart.
I guess its useful to see the table and chart at the same time.
I am about to buy a maestro ecu from some one that has a base tune for his ko3, I will be using 830, 870 or even 1000 injectors.
I wanted to know if I am able to open the Maestro suite and just change the injector size with tabs at least to get the car running. or will I have to make a new base map my self?
I also wanted to ask
The first maestro cables that were sold were sent in for new ones correct? If I still have the old cable can I still update the software and then use the old cable on it or do I have to send in the old cable?
?
Hansi
06-07-2011, 02:56 AM
pape: You should be able to get the car running using the Injector Wizard, or perhaps better, calculating the injector constant value, you can find a formula in this thread, and finding the BVC values on the internet (if you will be using Injector Dynamics injectors at least). This should get your car running "OK".
Regarding the cable it should be OK, to be certain contact Eurodyne. I believe you have a function in EuroDyneFlash called check cable firmware, something like that, to make sure you have a usable cable. You can update the software even if you have an outdated cable, but you might not be able to use it to tune your car.

am going to be using the sellers ECU, Cluster, and key immo chips.
I think it should work am going to try and swap the stuff this week.
and I will be using delphi 830cc not the ID1000 because It looks like the ID1000 need the 3bar FPR for a good idle and I dont want to run a fuel return. besides the selers ECU has a 830cc base tune that ran and idles good so I could start from there.

Why not just get Tapp to disable the immobilizer?
The car I am geting the Maestro ecu from is actualy going to be sold in stock form so I am trading my stuff for his. The ECU has the IMMO turned off, but My factory ECU has to be installed on his car also so I have to trade everything or swithch the immo chips on the ECU but then am not sure if that would work.
Where did you hear you need a 3bar to get a good idle on ID1000s?
I read that here or on vortex but might just be that the tune been used wasent correctly set up. A friend did tell me that tony palo installed the id2000 injectors on a stock integra just to show him how the idle was and he said it idle like stock. So if the 2000's were able to do that I dont see we the 1000's shouldnt work on our cars with the 4bar FPR

Yeah.. I wonder which of the IDs are the best option for the 1.8T.. With best option I mean as big as possible but still maintaining a fairly decent idle (I don't mind having to up it to ~1000 or even a bit above) and most importantly, part throttle. I think the ID1000s will work OK, but it would be reassuring if someone had tried them with good results before I bought them.

I wouldn't recommend scaling a MAF. I never had much luck with scaling MAF sensors in different housings, and i tried MANY different methods, not just the one on bananas' spreadsheet. You're better off just using the MAF housing and sensor from whatever car you need........TT225......B5S4......B6/7S4. If you DO have to scale for whatever reason.....make sure you do not forget to put in the correct offset value.

Injector Constant? or Battery Compensation?
for injector constant, see post #73
For BVC, use the injector dynamics ID725 chart as a starter to get the curve shape right.
http://www.injectordynamics.com/ID725SumData.bmp
Then use your LTFT to figure out what you need to add or subtract from the whole table.
Just an FYI, you need to convert ID's microseconds to milliseconds in order to use these BVC's in Maestro.

You can use an online converter, or just move the decimal three places. IE if the ID value is 2270 microseconds, your Maestro value will be 2.270 milliseconds.

If the spray pattern is correct for the engine's combustion chamber you can get any sized injector tonidle fine.
With the abilities of maestro I don't see why you are so worried. ASP got my Seimens 875s (over 1000 at 4bar) to idle like stock the first try. They also got custom Bosch EV14 1000s to idle like stock too.

and the 875s are "pencil" injectors and are actually not designed to be used with multi-valve engines.

The injector constants are still out to lunch. I don't know where he's getting them from, but they are not right.
Injector constant = mathematically calculated based on engine displacement per cylinder and injector flow at your system fuel pressure.
it seems as though the numbers are just a blind guess....
Edit: Actually after looking at the numbers for the battery comp values.........they are for 3 bar. NOT 4 bar which our systems run off of.

my car runs & idles great & block 32 shows 2.6 idle correction & -0.7 partial throttle.
i started out with 0.044976 & kept adjusting untill my partial throttle values came down.
i was also hoping that someone could give me some tips on how to pull out fuel &
bump up timing, since i just added an aquamist meth kit.
i know timing is adjusted through the 'pump gas timing map',
but which map would i use to adjust fuel?
would it be 'full load lambda'?
any tips or suggestions would be greatly appreciated.

I tried flashing a file to my maestro ecu last night and It would always stop at initialization failed no mater how many times I tried. It would ask me to turn on and off the ignition and then say initialization failed. do you guys have any idea why this happens?
I tried contacting chriss today but I was told hi was out of the office all day.

For those who want to run a V8 Bosch MAF, I've come across an interesting change in scaling instead of just selecting the profile in Maestro. I've used bananas' maf scaling tool, and it seems like it still needs to be scaled despite simply choosing the V8 profile in Maestro (green celled values to be entered):

The green values tell me that the MAF profile is too large than it really is. It is measured as 86mm ID in Maestro when it is really 82mm. That is 10% variance. Maestro's MAF offset is 200, which in the MAF tool says it should be 181.828, which leads me to believe the following:
- MAF is reading too much air than it is really getting,
- causing the ECU to inject more fuel than it needs on start-up,
- bogging the engine and creating popping sounds in the exhaust and it stinks of rich fuel.
Things I will try:
- unplug MAF to see how it starts up; if it starts up fine, then:
- scale MAF in Maestro using the applied values

The MAF profile in Maestro has nothing to do with Chris' scaling worksheet.
You are using an OEM sensor in it's respective housing.........therefore the curve does NOT need scaling and the offset does not need changing despite what you may think. The linearization curve is DIRECTLY out of a V8 S4's ECU cell for cell. And the 200 kg/hr offset value isn't just some random number. All Bosch MAF's (sensor and housing combo) have an offset of 200 kg/hr......because that sets the voltage vs. flow curve to Zero at 1.0 Volts...........So the value at 102.4 on the curve is what the offset should be set at. If you're scaling a MAF, it's a different story.

I got it to run pretty well, but i was still seeing some major fluctuation in for 02 correction before it would get back into check, and the idle would over correct as small openings of the plate would cause the car to cough for a second.

I've got kind've a stupid question..........I've just recently added a B6 S4 MAF to my setup after being MAF-less for over a year, and now, my fueling is totally out of whack. Since adding the MAF, my warmup correction and idle are VERY lean.....and light load and light boost are very rich (I haven't dared taking it into higher loads).
So my question is, how do I differentiate between adjustments that need to be made to my IC and BVC values from those that I should make to my Flowmeter Correction table? I've returned to my original calculated IC and increased the BVC to no avail....
Some advice would be much appreciated.......been running MAF-less cars for 3 years now, so I'm somewhat clueless
MmmBoost

Tune one item at a time is the only "real" way to know what to tune.
When I first installed my B6S4 MAF I installed my factory injectors and copied all of the relevant tables from a Stock B6 file. The only problem with that was the stock injectors are so tiny that I could only tune the lower portion of the MAF Correction table. After that was done I put back in my larger injectors and looked at how my O2 corrections were in the portions of my tuned correction table and then made adjustments to my BVC and IC. Then went on to tune the remainder of the MAF correction table.
JumboBlack1.8
07-15-2011, 06:27 PM
So, would you suggest returning to the values I used when MAF-less (LTFT were close to 0 in both idle and part throttle), then tuning my Flowmeter Correction from there? I'd think that'd be the only logical step for me, since I don't have many stock parts laying around.
And lastly, for tuning that MAF correction table, do you use the same method typically used for the main fuel correction table (i.e. log, input average correction, rinse and repeat)?
I really need to crack open that Bosch ME7 Documentation file and start reading....

i stomped on it a couple times on my way home & in 5th gear, i hit about 28psi before i let off. i don't understand why it would peak @ 25 psi on the way there, then go sky high after even though i made no changes...

It spikes higher because you are starting at different rpms when at the track. Don't switch to mbc. Rather, install an mbc in parallel and set it your maximum desired boost to control spikes but retain n75 for drivability.

One last question on this......wouldn't tuning the MAF with the theoreticial injector values (i.e. calculated IC and manufacturers BVC) essentially achieve the same thing? For instance, could I input those values and tune the MAF Correction table without touching the IC or BVC???......Or would I be running the risk of not tuning the MAF to "real" values, but rather simply in relation to the injectors?....The reason I ask is because it seems I'll inevitably run into a similar problem because the stock injectors aren't capable of flowing on the upper regions of the map........I ordered some ID1000's over the weekend, so I'll have an accurate injector flow summary.

If you don't tune one changed item at a time, then you're really don't know if you're tuning the right thing. Not to say that it's the end of the world......but when you make multiple changes and then tune yo're really only just tuning to make everything work together which may prove to be more of a challenge since one value may be compensating for another value and in certain situations may cause oddities.
With Injector Dynamics injectors though....you have a much better shot at isolating the MAF as the source of where to tune......especially if you have a rising rate FPR setup.

The linearization map and offset map which converts voltage to mass flow will be the same because that is calibrated for that particular sensor/housing combination.......but there is a MAF correction map that is there to correct for any areas of the map which may cause turbulence and affect readings. This will be different from vehicle to vehicle based on intake design/setup. This must be tuned every time.......unless you are running an intake/airbox/accordion hose in exactly the same orientation as a B6S4.

I do have a rising rate Aeormotive A1000 fpr, so I MAY give it a shot with the ID1000's when they arrive......For now, I'm experimenting with my EV-14's to see what effect this method can have (theoretical IC and BVC, and Flowmeter Correction table set to 1.0001 throughout).......So far, the only oddities I've experienced are some rev hang when letting off the throttle, and some bizarre intermittent engine load issues on warmup (I MAY need to ask for access to the 2nd warmup correction map to remedy it, if my theory is right)......From what I've read, the downside to this method is that, if you underscale the MAF, you'll get abnormally low load values, which will certainly alter a variety of other tables. With that in mind, I'll try to be prudent with whatever changes I make to the correction table.

Put in your values for the injector "knowns" and then get out a log. Keep in mind my BVC values for my KNOWN ID725's still need a little tweaking. I took knocked my values down to 70% or 75% of what the values should be.
This was Tapp's response to me questioning having to do this:
The curve should be correct, so you should preserve it by scaling the whole
series of values up and down together, but you definitely need to adjust the
table anyway... I know because I have tried the same approach.
If tuning were just a matter of plugging in a bunch of theoretically correct
values they wouldn't need adjustable tables in the ecu...
........my issue with the last statement is THEY ARE NOT "THEORETICALLY CORRECT" they are ACTUAL numbers the ID injectors are calibrated to.

Underscaling a MAF means purposely lowering the linearization curve on a small MAF so you're not maxing it out and compensating for less "measured flow" by overscaling injectors. This is a pretty quick and dirty method some people use to "make it work"
Since you're running a proper MAF with it scaled properly you won't have these issues. You're not going to be adjusting the flowmeter correction map +/- 30%.....maybe like 6-8%
Im curious too, I dont know how you would "see" turbulenace or problem areas from maf readings and then to make the necessary changes to the maf correction map.
O2 corrections will be farther away from 0.
The compensation map is to correct for expected mass flow vs. actual. If you normally see +/- 4 O2 correction and then see an area of the %Load vs. RPM map that is adding in +10% ........you know that you have some adjusting to do in that area of the compensation map.

Whats the safe max rpm limit for a stock aeb head?
JumboBlack1.8
07-29-2011, 06:27 AM
^^I wouldn't rev above 7k on a stock head......even that might be pushing it, depending on its condition
Got another question......I've dialed in the lower portion of my MAF Correction map (using stock injectors), and I've installed my ID1000's and gotten my idle and cruising AFRs to a good state.....However, things still don't feel right. My injector pulsewidth is way too high (between 1.9-2.1 at idle), and my timing is retarding quite a lot (between 0 and 3.75 at idle). Also, my warm start fueling is reallly lean, and stays that way for a few minutes after restarting. I also log some low-load misfires in 1st and 2nd gear.
My theory is that my minimum injector pulsewidth value is too low, and my TVUB values are probably a bit too high, which are combining alter how my MAF calculates engine load........Would anyone out there with ID1000's mind sharing what their minimum injector pulsewidth values are? I'm currently running .75ms, which is what the base file came with (so its likely VERY wrong)....I'm guessing I need to raise this value a good bit...
TIA. It'd be a big help

Also, my cold star o2 corrections oscillate quite drastically as well. Once it reaches operating temps, they stabilize to +/- 1. My LTFT at idle are spot on as well.....but I know something is wrong

What are your idling lambda values?
Throw up some screens of your TVUB, KFKHFM. Have you tried experimenting with a lower minimum pulsewidth? I had some issues with my idle as well, I did many things thinking it was these maps:
-warmup correction
-cranking fuel correction
-minimum pw
-bvc
-dying fuel filter
All to no avail to fix the lean condition at very low loads / rpms. Finally set my KFKHFM to 1.0 across the board, then raised the lower portion of that area to a higher multiplier so that my engine was getting correct fueling there. My intake and MAF position was causing the ECU to be reading a lot more air than I was actually getting, causing the issues. At least this is what I think, I could be wrong.

Everyone will have to modify their KFKHFM (http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=555.0;attach=957) as the intake setup is not the same as a stock B6 S4 intake with the accordion boot and box. It's a case by case basis.

What are your idling lambda values?
Throw up some screens of your TVUB, KFKHFM. Have you tried experimenting with a lower minimum pulsewidth? I had some issues with my idle as well, I did many things thinking it was these maps:
-warmup correction
-cranking fuel correction
-minimum pw
-bvc
-dying fuel filter
All to no avail to fix the lean condition at very low loads / rpms. Finally set my KFKHFM to 1.0 across the board, then raised the lower portion of that area to a higher multiplier so that my engine was getting correct fueling there. My intake and MAF position was causing the ECU to be reading a lot more air than I was actually getting, causing the issues. At least this is what I think, I could be wrong.
Before installing the ID1000s, I zero'd all fuel correction maps (Injection correct, main fuel, and MAF correction) to 1.0001 and installed stock AWM fuel injectors. From there, I began dialing in the KFKHFM map using the appropriate TVUB, min. injector pulsewidth, and KRKTE values for those injectors. After about 4 days of tuning, I arrived at a KFKHFM table that produced +/- 3% correction factors at both idle at low rpms.
When I installed the ID1000s, I recalculated my KRKTE, input the supplied TVUB values, and put the Min. Injector Pulsewidth back to .75ms.......Since doing that, I've only slightly adjusted my injector constant (lowered by about 5%) and my TVUB values (might've raised it about .06ms)......I'll post a picture of my Flowmeter Correction Table once my laptop stops acting like a bastard, but there are a fair amount of lean spots in low-rpms between 40 and 90 load. In those spots, I'm adding as much as 8% correction, which is on the high end for what I'd liike.....and its' STILL occasionally lean. So....something definitely isn't right.
As for lowering the Min. Injector Pulsewidth.....I have yet to do so. I'm waiting to hear what values other are running before I play around with it (because it will result in me needing to change a number of other things.......I'd rather not chase my tail on this).
Also, my MAF has about 4" of straight airflow before the 90-degree bend (in a 3.5" to 4" reducer).....my MAF readings are between 14 and 19

07-29-2011, 09:23 AM
Alright. When I get back home I'll post a pic of my flowmeter correction as well. I had to add quite a bit at the low-rpms in the same areas as you between 40%-90%. Something like 15%. Remember, there has to be turbulence and crap going on when running a huge V8 MAF on a dinky 4 cylinder especially at idle / low loads, the readings will be way off of a stock V8 idle and air flow.

You cannot set your Injection Correction map to 1.0001 and then tune your MAF expecting that all fueling irregularities are due to the Flowmeter Correction Map. The whole point of putting STOCK injectors in was to use injectors with accurate corrections associated with them. You must use the injection correction map for the stock injectors when tuning your MAF.
......on a similar note, you must also use the standard 4-bar returnless style fueling for the injector correction for the stock injectors to be valid as well. Tapps "Injection Correction Map" is Bosch's map FKKVS - Korrekturfaktor Kraftstoffversorgungssystem...which translates to Correction factor of the fuel supply system

The whole point of putting STOCK injectors in was to use injectors with accurate corrections associated with them. You must use the injection correction map for the stock injectors when tuning your MAF.
This is precisely what I told Tapp when I emailed him asking for the stock injection correction map for my car......but he assured me that a map base on a "stock setup" essentially wouldn't work for a car with my configuration.........I didn't quite believe that, but decided to give it a shot anyway.....and now, I've winded up with fairly inconsistent results
Here's what he said:
"The injection correction map is supposed to correct for variations in fuel delivery due to intake manifold resonance along with the injector flow.
I doubt a stock map will be correct for a setup like yours."
Now, it appears I've got the results to prove that I have a need for that map.....

Some cars actually do have FKKVS set to 1.
Let me look through my files and see if i can find a B5 A4
This is the actual definition from Bosch
The characteristic field FKKVS corrects errors in the fuel system (pulses in returnless fuel systems)
The map size of FKKVS can be extended to about nmot tevfa_w = 10 10 auf 16 10.
This is especially important to simplify the application for proportional systems. The speed sample points should match the number and values of the map KFPRG in the function BGSRM

Please bear with me... [headbang]
I loaded it up and changed the IC value for my ID725's to .044 after calculating for 2008cc. I also attempted to scale the MAF for my 3" housing but I'm not sure if i'm doing it correctly. I used Bananas' spreadsheet but I'm not quite clear on if I'm implementing it correctly. Basically, I'm not sure if the values are saving to the maps or not. I choose the 2000 S4 MAF in Maestro and then input the correction values but I don't know where to get confirmation of the change.
Anyways. The idle is not too bad, but the minute I fully engage the clutch after rolling from a stop, I get no throttle response and the car either dies or just coasts at idle speed.
Any help?

08-09-2011, 08:09 PM
If you plan to use the scaling method you MUST choose the STOCK MAF profile for your car.......THEN scale.
If you have the sensor for the S4 MAF just run the whole MAF and sensor combo. Save yourself the trouble of trying to scale. Scaling yields "meh" results. If you're ok with "meh" for the primary value for your fueling ccalculations then roll with it.

Scaling up the teeny AMB sensor that much is going to yield a MUCH larger % error than scaling into a TT225 (60mm) housing for example.

Choose the AWP scale which is the same as the AMB. I don't know if the AMB is listed. Been a while since I've looking into MAF linearization curves in Maestro.

It depends on some other values in your tune, but it's pretty possible. .....but you really need to get a gauge on there and verify what your fuel pressure is.

Apparently there is a reoccurring problem with late model B6 that causes the initial flash to have the symptoms I described. I attempted to reflash but flashing the same file only verifies the checksums, it does not actually write over everything. I was sent a different file to flash and it worked. I don't think it was important what the other file was, it just had to be different from my original base. It happened to be a 630 file and I just changed it to match my 725's.
I'm actually very, very impressed by how well the base file is running. I thought I would have to put in quite a few hours just get the thing to make it around the block. All of the information I've gotten from others helped a lot though and I was able to input calculated values right off the bat that are pretty darn close so far.

Nice! I'm interested in some logs.
Here's an initial log. I'm a little lost on where to start tweaking but I'm continuing to read as much as possible. I'm more interested in getting my lambda values correct and dialing in O2 correction, rather than making power at the moment because I need to pass emissions before Sept. 23. My previous tune was pretty ragged and was running far too rich to pass emissions.
Any suggestions based on the log are very appreciated! Keep in mind I'm running the AMB maf sensor in a 75mm housing and I have the AMP map running with no scaling.

When tracing a histogram for average values, do you have to let it run through the entire logdata in real time or can it simulate it quicker somehow? I absolutely love this function so far but it's just a little painstaking on a 20-30 minute log.

Yes, I bricked my ECU. Do I have to send it to Tapp to have the stock file placed back on it or has anyone found a way around this yet ?

Make sure your log has the correct column headers.

Make sure your log has the correct column headers.
This happens with all of my logs. Even those I was previously able to load.
EDIT: This was actually the problem. You can not load log files that do not have the correct headers. Such as those created by the Maestro Logger during a session that overruns the data limit for a single file.
MmmBoost
08-23-2011, 03:21 PM
Sounds like you need to uninstall Maestro and re-install.
The only time I've seen that error is if my logs are missing headers or if I try and save or open and then hit cancel instead hitting OK.

08-23-2011, 05:00 PM
Actually, you were right, Chris. I was trying to load log files that were created as an extension because of the data/time (?) limit they must have for a single file. All the files created after the first one for a single session do not have the headers in place.

Hey im pretty new to the tuning stuff and all the stuff in this thread is Chinese to me. I just have stock turbo but i intend on reflashing my car very soon as i now have a few mods that i wanted such as intake exhaust hfc and injectors. I really dont think i would know what to do with all this and the program. Is it easy to figure out and use or since im local and tapps shop is a 2 min drive from we would you think it would be best for me to bring it to him in person so he can tune it himself? I think he charges somewhere in the 800's for a tune but i know he gets it bang on. Would it be worth it for me to just have him tune it or would it be more cost effective if i just purchased it for later on down the road and figure out how to use the software? i plan on leaving my car the way it is with mods besides and intercooler for a couple years. What would you guys suggest?

If you don't have aspirations to move up to a bigger turbo, just get the stage 1 chip tune from Chris Tapp since he's near to you.

yeah thats the other thing he has ridiculous amount of work and is always hard to get a hold of him and such. I may just go with one of the basic tunes from apr or giac or something along those lines but id much perfer to have tapp do it. One of my buddies a while back got his jetta chipped from there and i kid you not it was the fastest jetta around for just an intake and chip . It ran 14.5 the track which i though was pretty damn good for the mods he had. Im hoping to hit at least that with intake turbo back exhaust injectors and stage 2 tune. And i know if chris did it, it would defiantly be possible.

Don't tune your own car unless you are willing to put in a LOT of time figuring this stuff out.
Motronic 7.5 is not straight-forward like an aftermarket stand-alone unit would be.
Robert Bosch doesn't fuck around
Period.

Yeah thats what i figued. im really impatient and just generally not good with things like that. Just wondering what you guys would think. When i get my car back from the body shop im going to try and get a hold of chris to see if he has any time within the next couple months. Like i siad im impatient so hopefully he will have some time to do it cause id rather not have to get something like apr thats just a generic tune.

Well, I've been generating about 2 revisions a day for the past week or so, logging during my commute to and from work mostly.
I've got my LTFTs down to 3.375% and 0% with an IC of 0.03649839 on my ID725's (2008cc). This constant is quite a bit lower than my originally calculated value, but fueling seems pretty good now.
I still have yet to fix my restricted fuel pump issue that is causing erratic fuel pressure at idle.
I have yet to mess with the boost or timing at all and I'm getting some pretty bad boost creep from 0-5psi. I'm not sure what the cause is, but it was happening with my old tune as well. I have a new N75, but I haven't installed it yet.

This thread got me through a lot of setting up my base file. Thanks everyone!
I just need a new oxygen sensor that doesn't read a fixed 14.7:1 AFR and allows the ECU to read whats really going on and make O2 corrections....[facepalm]
Lots to learn, lots to read, but I love learning. Especially if its about something of interest of me.

https://docs.google.com/spreadsheet/ccc?key=0AsoYZ-Uz9mA2dGZNZXR1MFUyRDhUTTU4cml5MU5LN1E&hl=en_US#gid=0
At the moment, I'm running somewhat close to a base file, as I'm dialing in a new S4 MAF (so the Flowmeter correction table is the only fueling table I've made corrections to). Currently running ID1000 set to the values provided with the flow sheet.
Any advice would be MUCH appreciated....

Where you having issues with this on your previous MAF?
JumboBlack1.8
08-29-2011, 02:51 PM
Yes I was......it seems I'm running lean at the spots where knock is present. But, at other times, there is a rich condition that ALSO produces knock in those same spots.......so, whether I increase or decrease fuel, I seem to be getting the same results
*EDIT*
Also, I'm not sure if this is relevant, but I'm running a TEMIN (Min. Injector pulsewidth) of about .74 ms

what injector constant are you using? and when you used the ID dead time table at what psi did you use it at?
JumboBlack1.8
08-29-2011, 05:02 PM
Used the numbers at 43.5psi. Since I've got 2009cc, my injector constant is .036852. I haven't changed either yet because I tuning one thing at a time.

When I refreshed the block a few months ago, I retorqued them to spec. I haven't heard any audible knocking. But the knock detection is coinsiding with very high ,o2 corrections......so I believe its REAL knock as a result of wildly incorrect fuel mixtures

Are you confusing knock with timing correction. Just because the ECU is showing timing correction that does not mean you are getting knock. The ECU will pull timing for a wide variety of reasons.
If you want to monitor real knock, you have to look at knock sensor voltages.
JumboBlack1.8
08-30-2011, 12:20 PM
I suppose I am confusing the two.....I have yet to log knock sensor voltages, but I will do so soon. However, the ecu is atill pulling as much a 6 degrees in low loads. I think its definitely a result of some fueling value being way off. Any ideas why I'm running SO lean at low rpm? I can post my values and maps if necessary
