Week ago I decided to change tune, i've done it 22 times already and this time was a charm - it failed mid progress! Prompts to return to stock but no luck. I've tried charging battery, connecting negative and positive, i bought new cable, i turned key as fast as can when it prompt and nothing! Car is dead, doesn't start, shows all kinds of errors.

SCT guys are great, but no help unfortunately.

Should I just get new PCM? And then sell tuner to lucky guy or girl? :)

Took it to dealer, they wont be able to look at it for a week. I'm without truck for week and half already.

Btw, apart from psychological effect from tuner there wasn't any actual on truck. So unless you have turbo - tuner isn't worth it.

UPDATE:
PCM was fried and replaced by Ford
 






thats crappy luck

I always write the tune with the ignition off / key out so there are no battery drains that could cause potential issues.

Very odd your ecu was fried.
