Sorry for a dumb question, but during WOT the ECM goes open loop which means the O2 sensor is ignored. But yet I'm still seeing STFT adjustments during the WOT pull. How can the ECM know about rich/lean conditions and make adjustments if the O2 is ignored?
Additionally, during WOT, PE is basically my source of fuel parameters but if I'm seeing STFT adjustments, what table would define the amounts (the limits of) what the ECM can apply for STFT?
