Hello everyone.
I've been having a problem for months that I couldn't solve. Long story short, car drives very poorly with MAF, ps_w and rl_w are too high, hence ignition is retarded. With MAF disconnected, it works almost ok, except in both cases i have part throttle torque interventions up to 2000rpm(audible timing retard and then throttle closing; less noticeable with maf disconnected).
Engine is pretty much stock 1.8t AUQ, only mods are: - FMIC - 3 inch turbo back without cats - oil catch can vented to atmosphere - cone air filter - 4 bar fpr - deleted SAI, EVAP and secondary o2.
No boost/vacuum leaks, DV is not leaking, MAF is ok (I've tried 3 different ones from working cars and no difference, all 049s which is afaik the correct one for wideband ecu). I've reverted bin file to almost stock, except deletes and few more tweaks.
I hope someone has an idea what could be wrong, because I'm banging my head for quite some time now.
I did two 3rd gear wot pull logs, one with maf, one without. Logs and bin attached.
Thanks.
