    Is the 7G Tronic transmission supported? I read from a W204 C63 and the OS for the TCM populated but the hardware doesn?t.

    Really would kill for me9.7 support for my daily m273 w212 e550

    Spent a decent amount of time on our m278 e550 with hpt..

    Its a damn rocket but I am still struggling with throttle limiting, and getting rid of the cut that stops you from brake boosting from a roll.

    If I can address those last two things figured out.. this thing will get down like a clown for a street car.

    Any one know what is max throttle angle on the M156? On full throttle pulls, only getting 86% reported with limits set to 100%. Just wanna know if that is max limited by hardware and not a software issue.

    On my car a 100% throttle command nets 86.7 at the throttle. 85.5 to 87 is the max I see on other benz, which I assume is what the sensor sees when the throttle is against the stop. The most I've seen mine closed is a command of 1.6 and the position reads 12.5. I assume that is against the other stop.
    You can also do a throttle check with Xentry, and no doubt other tools, where it fully opens it and reads the same 86.7 on mine.
