OK,
So i have a 07 Colorado that I'm trying to tune. Load all my HP tuner stuff onto new laptop.
Pull the stock file off the truck
Purchase Lisc update key on cable
Make tune changes
Go to reload tune and it times out (bootleg timed out)
Tech support tells me it is a car issue
Do some checking pull fuses and relays and such
Get the cable to do a "write only" on the truck
try to do a "write entire" on high speed or slow speed and I get a "unknow error code 8A"
The vechicle will not start or crank now
Any help would be great

THANKS in advance for any help
