One last comment in defense of the instructions that said to put the wide-band in the rear O2-sensor location. For WOT tuning, this is fine. In fact, many shops still shove a probe up the tail-pipe when a customer shows up without a wide-band installed. But when the flow through the exhaust is low and/or slow, it can give funky readings, due to the delay between what's happening in the engine and what the sensor reads. If you aren't actually tuning for something other than WOT, then leaving the sensor where it is will be fine. But I'd move it, myself, if it were my car. My sensor is in a second bung very near to the front O2 sensor.

 

I will move it, but I'm more concerned with WOT than anything !

I looked and I'm getting Mixed signals on whether the aem requires a pure air calibration at key turn or the start up with cig lighter is sufficient. I looked the only 12v constant I have is radio that causes a weird noise in speakers(normal prob), ignition stays on, I'm not sure if headlights would work or not as a source that does not reset.
