Can't detect ECM??

[calabria69]

Trying to tune an '05 lly and it says bootloader lost cannot detect ECM?? For some reason. It won't read the ECM, I've checked all fuses, tried alt keys and no response, the check status doesn't work either?? I'm at a loss, any advise would be greatly appreciated.....

What version of software are you using? Have you tried the Scan & Tune software (the new stuff)?

EFI wouldn't read mine until I put the factory radio back in. Still not entirely sure why it matters, but it solved the problem most ricky tick.:thumb:

pulled the radio and amp fuse and it worked... learn something new everyday, weird shit....
