I see the SS on the main page, but in your V8 section, you don't show the LQ9 engine.
Do you have special maps and tuning to handle the LQ9 engine or is it similar enough to the LQ4 to work correctly?
Do we need a special cable like the LS1 Edit? Or can we connect straight into the OBD11 interface below the steering column?
I have Onstar, do I need to disconnect it to get your program to work?
