It is kinda hard to pick on the throttle. All it does is add more air to the engine. The ECU tells the injectors to fire longer. The rev counter in the ECU tells the injectors to fire more often.
The 'Guino sees faster vss and faster, longer injector pulses.
The MPGuino calculates fuel used from those 2 parameters.
The only thing that may be the culprit is this below. I think I have it set to 500.
Injector DelayuS - Represents the mechanical delay of the injector in microseconds. Advanced topic.
I will try and reduce the number, maybe to 250 and see what happens.
My theory is the code trips up on the bigger number. Maybe I'm thinking backwards.
I'll try it soon.
