Pro Tip: If you post under Diagnostics attach file and logs. 

1. learn basics, read wiki, its the limit in the code, search for 5120hack
2. maf
3. depends on the graph, logs?
4. injector open time in ms or duty in %, logs?
5. file, logs, what marty wrote

If you ask for help, attach everything we need to help
Your attached files will stop newbies from asking the same again and again.
Do it the right way.

Hey there,
Thanks for your input. It always helps. I always take logs so I've attached a sample run from 1800-6500rpm WOT. The boost spikes are usually a lot higher FYI.

To answer your questions:
1. Awesome, thanks, I read about it and setup the hack on my tune. It works even though MAF can't read that much flow.
2. I am using the factory MAF with factory size housing. I keep hitting the 5v limit and would like to go 3" housing and implement MAF scaling. I hope I can do it since I'm just learning basics. Maybe one of you can help.
3. See my attached logs and graph
4. Got these logged as well
5. See attached ;-)

Thanks guys. Looking forward to your responses!

It is the "old school logger", just not using the ecuxplot UI.  VisualME7Logger just wraps ME7Logger.  Seems he just modified the logs so they are un-parsable.

Sorry about that. I was just trying to post the log data from the run in the screenshot rather than the whole logging session. I've posted the whole session instead and you can find the run at 492 sec. Thanks and my apologies.

PS: I can post my ECU BIN if anyone thinks they would be able to make some quick improvements.

Sorry once again for my mistakes. It's very hard to get a good WOT run because the auto trans will downshift even in tiptronic mode if I push the pedal too far

I've been busy trying to do the bare minimum ECU tune so I can drive the car without blowing up the motor. I had to start from scratch since I made too many changes that had adverse effects and caused all sorts of problems including rod-popping boost spikes. My current file has been modified to run the 386cc TT225 fuel injectors at low boost and not much else.

If anyone could help me make some very simple changes to the file, I would really appreciate it. I just don't trust myself to do more than I already have with the injectors.
The next few changes I'd like to try to make is
1. Increase fueling a little for the E85 mix (enrich to ~0.82 under boost or high RPM)
2. Raise boost to ~16psi until 85% injector duty cycle
3. Any timing changes that should be done for #1 & #2
4. Code out the O2 cat codes P0420 and heater circuit code P0141

If I could get a little help on the changes above then I could take my time to do further development on this tune myself at a nice slow pace.

Attached is the mod/orig ECU plus a few logs with WOT runs. If you need the XDF to help with making some of these changes, just let me know and I can post it. Many people have already posted the 518AK XDF so it should make things easier.

Thanks for the help with everything!


PS: In case you need my hardware details, here they are again:
2004 AMB 1.8t B6 A4 Quattro Auto
ECU 8E0909518AK
HW# 0261208230
SW# 1037368072 v0003
Frankenturbo F21 Hybrid (28psi WG)
386cc TT225 injectors
2.5" factory MAF/housing
3" catless down pipe w/ OEM O2's
RaceTec front mount IC w/ 2.5" piping
Frankenturbo 3" Turbo Inlet Pipe
CNC piston style DV w/ 10-25psi spring

Thanks for your input. I've done a few more WOT runs to redline in 1st and 2nd; see attached. These logs should be a lot better and on point. They all look nearly the same with some funky stuff going on in 1st gear (it could also be normal, perhaps the turbo spooling/lagging or lambda adaptation).

Also what is this fixer tool you are talking about? I'd like to take a look. I will go ahead and try to apply the changes you recommended and report back.

I plot in ECUxPlot after I finish logging, but since everyone has a different opinion in how to represent the data on which axis and so on I just let each person load the logs themselves.

I need some feedback in regards to the strange boost/correction behavior in 1st gear. It seems the throttle plate closes after current boost exceeds desired by too much, and this doesn't happen in the other gears. Also, is a lambda of 0.89 acceptable for 7psi boost between 4000-6500rpm? Also how exactly should I tune the timing? I am able to add about 7 degrees across the whole board at any RPM without any sort of adaptation, retardation or BTS kicking in. Would it be safe to add 5 degrees or so under all conditions? I want to make sure everything is working smoothly before I raise boost, timing and more fuel.

Thank you!

I tried to do this, but unless I start at 3500rpm or higher, the transmission will downshift and ruin the pull. I'm not sure if there's anything I can do like disable traction control but even when I am in tiptronic mode it will downshift at 100% PER.
Does anyone have suggestions?
