I am getting an e67 ecu setup for a LSA swap car, so I wanted to start with a clean slate. Using a GM MDI tool that I use regularly, I flashed a 2014 Camaro ZL1 file into the ecu.
I them read it with HPT, and when I try to open the file I get a "Tuner Lock Error". How is this possible? And now when I try to read it again, I get the x35 Invalid Key error.
FWIW, I am doing this all on a bench flashing harness.
Any thoughts?
