Hello there,
I'm struggling with 1.8T BEX, car came to me with too low boost, I've checked everything, seemed ok, I also noticed too much timing retardations on all cylinders, we decided to remove cat, for my suprise almost nothing changed , about 50mbar gain of boost, I found that WG actuator is opening too early, I have adjust it, but adjustment range is over, I know WG actuator needs to be changed, anyway I have my boost, let's say, "back" to stock again, but there is about 10KW retardations
(
Spark plugs are brand new.
I have done some logs in ME7Logger, what I see there is IDC high, propably bad fuel pump? Or bad injectors? Tommorow I will do a measure of fuel pressure. Anyway retardations are high at mid range RPM, I don't exactly know what to next, excluding checking fuel pressure.
Here are 2 logs, first with MAF plugged, second with MAF unplugged. Car is totally stock, just catless.
Could you help me? Please
