Got my cortex today. updated it before trying to tune. When I tried to tune my truck, all I kept getting was general error "G-3F"
the tuner can identify my vehicle, read and clear engine codes just fine.
A few years back I once used my buddies bullydog just to try it out. Since then, I've returned the truck to "stock" after giving him the bullydog back. the only setting I didn't leave stock was keeping the fog lights on when the brights are on. Would this have anything to do with it? If so, is there anything I can do to fix it? ...Because he no longer has that Bullydog.
