    Default 2 bricked pcm's please help

    I made transmission setting changes to my tune and loaded it and it bricked the PCM. It ran all the way through and said flash completed successfully. When I hit OK my fuel pump went crazy and it wouldn't reconnect. I tried reflashing and full recovery and it just says PCM not detected. I pulled the PCM out of another vehicle and loaded the old calibration in it and everything was good. I then tried to load the calibration with the updated trans setting and it bricked that one too. I can't afford to buy new pcm's and licenses right now so I'm kind of screwed. What the hell is going on?

    What PCM/ECM and post the tune files please. Once we have that info I'd be happy to spot check the tune and then EFILive can take a look.

    My guess is you are messing with speedometer settings that are to wrong.

    That is possible. I was changing to a 28" tire for the track so I was adjusting tire size and shift points. If that's the case, is it recoverable? I can post up the file later.
