Anyone have a dyno with AFR of a z31 with stock ecu?
I noticed on many of my runs the ecu seems to get a pit lean as it switches to what I think is simultaneous injector mode from batch fire mode. Its mostly 1st or 2nd gear pulls when the rpm changes very quickly. Does anyone have a AFr reading from a dyno tune? Or any ideas as to how to fix the lean spike. The fuel maps are fine.
