Hypertech Code 69 + Dead Vehicle
Just purchased a Hypertech MaxEnergy for my 04 Expy. Was going through the programming no problem .... started to write the new program, and I get a "Code 69 - Unable to write to computer" - Contacted Hypertech. My vehicle is now completely dead, and of course Hypertech Tech Support is only open on M-F! AAAHHH. Guess I take it to the dealer and probably have a fried computer?

Hopefully not. If you just started writing the tune, then it hasn't gone on to erase the stock tune. It was probably not able to communicate the read codes and copy your stock tune.
I have gotten lucky with just disconnecting the battery. I'd give that a try before going to the dealer.
