As for WOT, in this motor that is open loop, correct? So, with too much flow we are going to lean out the motor, possibly dangerously. ..
Yes, WOT for most EFI ECUs will bypass the O2 sensor input, which is only going to read lean or rich - I don't think the O2 sensor in our 22RE is a linear readout. In open loop, I believe AFR goes rich, not lean.
