So the A/F target map shouldn't be used at all? I would think with a brand new calibrated WB sensor and an engine that hasn't been broken in, it would be the safest bet to get a tune (using the A/F map) while datalogging and then tune the car without the A/F target map based on your datalogging results.
I'm pretty much using stage 3 wiring with everything needed to use the A/F target map from scratch with a brand new (not even broken in) 9:1 CR motor, new cam specs, new P&P'ed heads, TurboBob modified ECU, 880cc's, pretty much everything you could think of and then put a GT42 on top of it
Now if anyone has a better idea of how to begin to break-in and tune my car, I'm all ears.
