Hi guys,
I'm tuning a cammed LSA engine at the moment and am having issues with PE mode and when/how its enabled. I have the throttle area enabler set very low <15% and MAP threshold at say 80kpa. I can hold the engine at say 95kpa under load and its stays in closed loop. Its not until I get to about 120kpa that the commanded fuel jumps into PE mode.
I have also noticed this in non supercharged E38 Holden V8's so its not just a LSA thing. Its almost like there's other enablers in the firmware that we just don't have access to.
Its clearly NOT just map threshold and throttle area dependant.
Have other people struck this before and do you have any ideas as to what the other conditions may be to enable PE mode?
Thanks,
Mike
