    Question 2018 Hellcat Question - Tuning choices once unlocked

    Hello,

    Looks like next year (2019) the OEM cars will come with after-run timers on pumps and fans; I'm hoping someone here who has unlocked and tuned a 2018 (or older) hellcat can tell me if there is a choice in the software to put those after run timer values in, and how long (and short) the choices are. Don't have plans to heavy mod my car, but would consider dropping one pulley size, mild cleanup on my tune and add the cooling timers. Probably buy a second PCM to crack and not even sure I should bother yet.

    Input welcome!

    PS: Using HP Pro and LM-2

    Thank you.

    Not sure if it can be done via the PCM tune as the after run/cool down might be controlled by the Uconnect head unit. The reason I think this to be true is the Tazer from Zautomotive has a cooldown feature (firmware 2.3.0 and above) but it requires user input to initiate the cool down and it does this by modifying the head unit and not the PCM.
