i3 tuner

Post by jack haughton »

What could cause a failure to download program? My unit has done it 2x now and curious what may cause this can the program be loaded on the tow haul switch and leave the factory tune on the main setting? thanks.

No... that's not how the tow/haul button works... You'd just use the tow/haul button on the dash/lever like you normally would. That just tells the transmission to use different shifting settings, that's all it does. The engine tune does not and can not change at all when you press that button, only the tranny shift points change, that's all it does...

need to make sure your truck's battery has a good/full charge... nothing on/running in the truck - i.e. all lights off, radio off, fan/blower off, don't operate power windows or anything, parking brake on (this keeps the daytime running lights off), etc etc... and key has to be turned 2 clicks so that it's in the RUN position (and engine not running)...
