i was minding my own business the other day (in closed loop maf)
when out of the blue under hard throttle(40%+)
i was hitting lean (16afr+) :eek: for no reason.
i went into open loop with PE enabled to see if maybe i just needed more fuel
in my VE table but it was doing it in OLSD as well.
i have been hitting 85% duty cycle on my injectors as of lately ,
usually they are 75% and i have been seeing a high fuel pressure anomaly.
but for the longest time no matter how much fuel i wanted
i could get it by adding at will.
it seems to only be at the higher kPa areas only and it fluctuates,
it will hit my commanded then hit lean very rapidly.
i saw zero KR in the lean spots.
i am wondering if it is possible to be at the edge of duty cycle for so long
and be ok , then all then sudden be over the
limit of the injectors ability, or could this be a sign of wide band malfunction?
