My 05 legacy gt has similar issues. Had intermittent misfires and bad Air fuel ratios. New maf helped. Eliminated the misfire but im still getting 16-17 air fuel ratios at idle. The lightest tap of throttle brings it back to 14 though. Haven't been able to pinpoint any vacuum leaks. Maybe I'll try pulling the map sensor from another car and see if it helps. Suggestions appreciated. Havent messed with it much since I got my STI though

I have a 2010 Sti, ej20E motor. Was having a few issues so I took it to a tuner to have it tuned. Got it tuned and it spun bearings that same day. Bought another motor out of a 2008 legacy and installed it. Same Tune because I didn't have it retuned as yet. With normal cruise driving In less than Two weeks it spun bearings and so I scanned it and I got the error code P0014 B camshaft position timing over advanced.

Josh, for ACN91 pump gas tune, where should be the AFRs at? im assuming more rich right? like 10s???on WOT?
@delta-tuning
@delta-tuning 3 жыл бұрын
Hey, I'm not Josh but I tune Subarus as well. The answer is really dependent on other variable in your tune like how aggressive your timing map is and how much boost you are running. I did some reading on ACN91 as I've never used it, but it looks like its just regular 91 oct with some added detergents. 10.8-11 is usually a pretty safe AFR, though if you're not seeing any knock on your current tune then I wouldn't worry about it. If it's in the low 10's on your AFR gauge then you could likely lean it out a bit more, but again it depends on the timing and boost.

yellowsubie thanks for the reply man!! also, is it usual that the wideband on top of my downpipe post turbo, reads richer than the actual narrowband of the car on the front? i do know the fuel trims are still dictated on the front sensor, but how is the afr adjusted using the wideband? do u still follow front?

@@BaderBuiltRacing cant wait to see cause of that quite high oil pressure... Im guessing it was some thick oil viscosity used like 50 or 60 weight oil? Along with too many oilpump relief valve shim... Is the engine built? Bevause i can hear cold start piston slapping... If the engine was bone stock ej207...better do leakdown test just to be sure that there is no ringland issue... And last thing...if he really have ej207, using 205 ecu or some other jdm wrx (non sti) ecu map, that mostlikely causing some minor issue super rich at cold start and choppyness on low speed low rpm rolling drive...
