    What model haltech are you running, i know the sprint 500's can't control the idle stepper motor properly.

    If you give haltech a call, they'll support you on the phone, every ecu sold comes with support.

    Itís an older e8. Last time I sent them an email they pretty much said that itís a prehistoric ecu and they donít make parts etc anymore. Donít think theyíll be much help.
    The guy who had the setup wasnít running it. So Iíve added it to the build.

    Is the 20V ISCV like the ZE? Three pin, with 12V in the middle and an "open" wire and a "close" wire?

    If so then I have a diagram for a circuit that will convert a single PWM wire into two signals for the "open" and "close" wire. I may even be able to dig out the parameters I used to control the ZE idle.
