I went to do a full re-flash on a friends LB7 to get him DSP5. Something went wrong with the burn and I'm pretty sure I crashed his ECU. I felt so bad that I even bought a bench harness from EFI Connection to try to restore his computer on a bench harness. 1644016441..
In the mean time my buddy bought a new ECU, same year truck 2004 LB7. He installed the ECU and the truck fired up right away, no VATS relarn needed. His security light stays on all the time. I tired to match the VIN with EFI Live and it gave me an error, said there was a communication problem.
What should be my next steps? I don't want to use another VIN License if I don't have to, is there any way to bring the original ECU back from the dead so I don't need to spend another $125?
If I can't use that ECU how would I match the VIN with the new computer so the security light goes off?
Thanks for the help.
