Seem to be noticing more instances where Inj Duty Cycle is different on banks 1 and 2(see attached screenshots). Normally it is only a small variation but on throttle transitions it can be large. I can't see any reason why they shouldn't be identical at all times while in OL/SD if the PCM/INJ Drivers are functioning properly. Any ideas? Pretty scary when the pcm treats both banks differently when the O2s aren't even plugged in.
During these WOT blasts it also started to break up badly as if spark was being cut off and switched back on(possible misfire). Didn't log misfire this time. Haven't seen any abnormal misfire levels on previous logs. No SES. Seems pretty repeatable if I am rolling about 60km/hr(40mph) and stomp on it. Kicks down into 1st, starts to scream for a second, then cuts out(nowhere near rev limiter), and then kicks in again and will rev to the shift point OK. But it has also happened in the middle of a run. The sudden TP drop may just me backing off when it starts acting up.
BTW. My wideband is now on bank 1 so who knows what the AFR was at on bank 2 when InjDC was at 70% on bank1 and 54% on bank2!
