I've been fighting this for years and have made related posts about "lean after flash."
I still can't figure it out, so I'm hoping someone can look at the log/tune and say "hey, you're overlooking ....!"
The car will idle slightly rich. I put it in gear and it's "closer" to stoich. I tap the throttle maybe 3-5% and the wideband shoots towards 1.5 (21 AFR GAS) and the car shuts off. (When the WB is 0.51, it isn't yet online)
Given how narrow I have to keep the inj PW 1ms, IDK if this is an injector problem (since it comes and goes) or I'm totally overlooking something in my tune. ATM, I have Cylinder Gain enabled, but that has no effect. I've tried adding 0.5-3.0 ms to the Makeup Pulse, but that doesn't seem to work either.
Ideas?
