    Demon trans tune in a Trackhawk

    Is it a straight copy and paste over or will the difference in gear ratios screw things up?

    I think the trackhawk is an 8HP95, is it not?
    If in doubt, multiply everything by 1.1.

    Yes. I figure that was how beefed up trans was, but don't know. Why I'm on here asking, don't want to screw things up.

    the setting is based on the output shaft sensor and not on the wheels. therefore, the main pairs of gearboxes do not participate here as in NAG1

    Please expand. I have a 2018 Trackhawk. Don't like the way Track mode shifts, falls flat, pops, then shifts. Thinking that has something to do with SC belt snapping. SC wound up, eng flat lines, SC free wheeling, eng engages, jerks belt, snap. Had it happen with a little light to light with a X5.

    a whistling sound would be heard if the belt slipped. If the compressor roller slips, then this can be seen from the inlet pressure. Is there a log where you can see the problem?

    I'm over exaggerating the fall on it's face. More like the computer torque management cutting spark/timing for the shift, it's just way over the top.

    I'm looking for a seamless steady pull between shift.

    It's not belt slip. The belt is literally ripped apart.

    My guess is the stalling of the eng during spark/timing cut.

    Clutched SC pulley free wheeling as eng power is cut, then power hits and grabs the SC pulley.

    That pulley operates on a sprag like the transmissions use. Grabs in one direction. free wheels in the other.

    Are all the pulleys native? I ran into a problem, the profile of the stream was too sharp. On 6.2, the belt goes green after all, reinforced.
    Does the pulley clutch work exactly? Bearings in the compress not wedge?

    Nope. Had Curt Dusterhoff tune trans, worth the price of admission. Now working thru the flex fuel tune.
