Thread: WOT cutout for A/C compressor

  1. #1

    Default WOT cutout for A/C compressor

    does the Atomic EFI control the...WOT A/C compressor shutoff?

    I don't think it would. It has an A/C trigger for fan control and load compensation (e.g. IAC, AFRs, timing), but no output for the compressor clutch.

    I'm sure you could rig some circuit up that made this happen. Once a voltage close to 5V is output from the TPS sensor, shut off 12V to the A/C clutch.

    Or you could use MAP volts, which I would.
    Many benefits, one is no compressor at engine start, no compressor at any medium throttle etc.

    I'd say with a comparator.

    There are many other ways, including a 555 timer to operate a relay depending on voltage input.
