Title: 2.7t a6 tiptronic limp mode?
Post by: em.Euro.R18 on October 08, 2014, 12:40:24 PM
Car will hit 2350mbar at wot during warmup but full operating temp or close you can see wbkda is limited to 20% while wped is at 100%. RL is limited to 116% because of rlsol_w but so for some reason spec is not following my ldrxn. Am I missing something? This is the first attempt on a 2.7t tiptronic.

Please make sure ME7Logger outputs with the .csv extension, not the .log extension... i have .csv associated with ecuxplot ..

From the looks of it boost request is stock?

LDR and IRL are not stock but I do believe it has something to do with a IAT limiter. I've recently noticed this only happens when the intake temps are high, coolant temp is at operating temp. Althought I've raised those area's 50-90*c in KFTARX to 1.02

You have busted wastegate lines. Don't bother tuning until you know how to verify the wastegates are working properly. Even worse, it is immediately obvious from your logs :/

Before IAt's warmup request hits actual so I donno how the wastegate lines are busted. I'll check the wastegate lines but honestly doesn't make sense.... When Iat's warmed up I did notice actual overshot request a bit but nothing to cause concern even with 20% throttle position and 0% duty 1400mbar is near wastegate crack pressure.

Although looking more into it I'm overshooting to over 2000mbar so yeah you maybe right. I was focused on the IAt's because it would only happen fully warm which really kinda threw me off from the big picture. I'm fully capable of checking wastegate operation I appreciate the input.  ;)

Unplug your N75 (electronically). Log the car. Post the log.
