Someone PLEASE explain how this controlls fuel under boost, in open loop! Our stock ecu's controll WOT fuel delivery by pre-programed injector duty cycles for the rpm band, and engine load. We adjust fuel pressures now to get more or less fuel under boost at different duty cycles. I still dont see how the SMC will know how much fuel to add(duty cycle) for boosted conditions properly, since the ecu isnt reading off of the o2 sensor at WOT to adjust A/F ratio (duty cycle). Maybe i'm just not gettin something...where are the guru's at :P
