Hi,
Hopfully an easy question for you techs.
What input/feedback does the Barra FG use to determine for acceleration enrichment on APP change?
e.g. You accelerate 3/4 of pedal, the APP sensor sends this to the PCM, does the PCM add AE here and open the TPS to desired position?
or does the TPS open first, feed its position back into the PCM,then the PCM add AE?
Additionally, how does it achieve the inital AE?
I would suspect under linear app/throttle movement, the injector PW would increase. Is this the same for initial AE, or is there function of additional sequential/batch injector firings initially in result of the AE process?
appreciate your time.
