I also was told I could swap the original and Mopar PCM whenever desired. However, I wonder how long it takes to recalibrate when you do so?
I think once the initial calibration is done to the performance ECU it's done? I've swapped a couple of times (thinking I had a computer issue), and the throttle response and the lack of exhaust popping were instant
Also, how long does it take to adapt to new fuel? If I load up with a 95 octane mix at the track, does the computer make the adjustments instantly, or is it 30-40 miles in various conditions? If it's the latter, it may be a waste of time.
As soon as it starts to combust, the computer is adjusting the timing based many readings including the octane
I have only driven with the Mopar PCM, as Mark installed it at delivery. My idle hangs in a weird way: it "bounces" down to idle when you are at rest, and surges up when you first let off the gas. It's been 1k miles, so it should be broken in. Anyone else have this issue?
