All my mods. Could it be my primary injectors are too large causing this to happen. I also was not sure if the Injection system stage 1 and 2 firing angle BTDC had anything to do with it......
I am logging injection stage 1 and 2 duty cycle as well out the injector output duty cycle and do not see 90% in any of the logs. Should I disable the feature in the injector diagnostics?
