Hello,
I'm currently still checking what could be wrong with my car. (1.8t auq)
Fuel pressure is 2.8bars, fpr works (shoots up to 3 bars when vac line disconnected)
Also tested while revving, spikes to 3 bar when demanding extra fuel (as it should)
NO vacuum leaks
Vcds tells me in mvb 032 and 033 that idle fuel trims is 0.4% and partial 12.x%
If i reset trims stft spikes up instantly to ~+15%.
Weird thing is: when going WOT fuel trims go -20 almost.
Basic things like pcv/dv/hockey puck etc all have been addressed and fixed.
MAF readings spike up to 180 g/s but only at around 4k rpm and at redline its more like 140 g/s
Car is also stage 1 chipped, i don't know where. I am planning to go stage 2 but wanted to fix this issue first
Here's one of the logs i have done
