    Dodge ram zf8hp70 on demand

    Hey everyone, kinda new to tuning. I'm running a 2015 ram 1500 and I want to be able to use my +/- shift buttons as an on demand shift not a hold gear shift but I can't seem to figure it out or find any info. I've searched and searched. One member mentioned it on a Cummins with a 8hp70 behind it but I did not get any difininitive answers on it. If someone could explain how to do this of if it's even possible for me to do that would be awesome!
    Thanks.

    Hey Hemi_power, have you made any progress with this? I'm working on something similar with a Challenger based setup in a Jeep. I've got forced upshifts working "most" of the time. I'd be happy to share notes. email me at rbrooks@performanceunlim.com

    Post your tune.

    Also, a short log where you are logging shift ID and using those buttons.
    If in doubt, multiply everything by 1.1.
