Hello,
I have a 3SGTE in an MR2 running a G4+ ST205 PNP ECU
Ive had the car running and daily driving with quite good results. I took the car to get dyno tuned and they cleaned up my fuel map and ignition map and it looks like I was pretty close with my street tuning. I took the car to the track and it functioned well.
The issue I am experiencing is occasionally knock occurring just after heavy throttle applications.
It seems to be related to my AFR. when everything is working properly, the AFR will closely follow the target or go slightly rich, but for reasons I'm unaware of the AFR will sometimes track late, causing knock, or it will drop, then bounce before tracking, and other times it track but on the lean side. i belive the temps and running conditions are similar during all of these variances so I hope someone could point me in the right direction of what to look for.
maybe one of my correction tables needs to be adjusted?
I have attached log files and my map.
Thanks,
Cameron
