Was curious if anyone knew a way to get the transmission to work as a trans brake like the demons have from factory?? Would this even be possible?? I dont know why someone with more knowledge than me could figure how to make this work assuming its just in the programming. I may be way off but im sure someone with more knowledge than me might be able to shed some light on this for me? WE already have lauch control and just need two gears locked a same time to hold the car in place.. Maybe its in the BCM??? i dont know just guessing, but if you could find how it works on the demon then why couldnt you adapt that to the HP80?? Or hellcat for that matter Maybe the guys over at Zautomotive have found a way...
