Over the weekend I licensed a friends car to start lightly tuning. Well the small changes I made to the car like the cooling fans to stay on after shutting off worked. However when i started making changes to his cruse timing something was really odd. Whatever I would set into the High Octane Spark Advanced table it would not show that during scanning. Like if I set it too 38 it would command like 46! I then proceeded to zero out the AFR Correction table thinking that was adding timing on top of the base table however it was still commanding way too much timing then what I had set in the tuner. Is there something I am missing that is adding like 8 degree's more timing on top of the base table? I checked the other tables like IAT, ECT and I don't see anywhere that it would be added that much more timing? This was even after the car was warmed up. This is a 1999 Buick Regal GS and I own a 2000 Buick Regal GS and have no problem like this.
