i tired to program ECM and now my car does nothing. when i hook up data master it says no "pcm sync" how do i get a program back on it?? do i have to buy another computer??

 

If you were reading it, then pull the negative battery terminal for a minute or two and you're all set. If you were programming it, then the PCM is corrupted and will require repair. I offer this service if you are interested. (you can check it out here: http://www.madz28.com/repair.php)

 

thanks that worked. i got lucky i guess. tunercat says "PCM invaild response"
why is this? datamaster works fine??? you are the master so i guess/hope that you can help me out. really appericate it.
thanks
