18:15 AFR at WOT

Mitco39

It should be commanding ~13 or so IIRC under load. As soon as it starts to get loaded it switches to open loop and the car is just going to meet its target AFR without even looking at the O2s. If your car idles fine right at 14.7:1 with no trim codes or other funky O2 codes then your good. I dont know how much I would trust that program your using. At 18:1 under load you would have 0 power.
