Hello all,
I have a 2021 1500 Sierra Denali that I'd like to do some quick modifications to. On my older 2017 Ford Expedition Limited, we used a tool called ForScan and could edit parameters on body control modules, change the duration of run time when using remote start and program your turn signals to flash a certain number of times.
My question is, what options do GMC owners have? I'd like to make the default (3 times) turn signal flash to 7 times. I've dug around the internet and found very little.
Thanks in advance,
Phil
