First off, forgive my ignorance. I have not worked with HPTuners in 3 years or so and have a urgent need
for help. After I post this, I will also hit the search but any help you can provide quickly would be appreciated.
I am trying to help a friend who need to get a car running basically yesterday.
He has swapped in a LS2 with Painless harness into a 1970 El Camino.
The ECU provided by the car's owner is the part number 12200411 called for by Painless.
I was able to read the ECU(junkyard ECU that the car's owner supplied) and the ECU has a VIN number for a
5.3 2001 GMC Sierra. We obviously need a vette or GTO tune to run the car.
The OS listed for the Sierra is 12202088. The 2005 GTO tune I found was a OS 12598977.
I seem to recall that if I tried to push a tune from a different OS, I will brick the ECU.
Please help me quickly.
Thanks,
Bradley Buchanan
