    Default Sniper & A/C

    I have not purchased SNIPER EFI yet, however, I'm well into reading the entire installation manual. I'm wondering how SNIPER works with A/C. Can it increase idle speed when A/C turns on? I believe I read of its ability to kill the A/C at WOT. I'm more interested in how it behaves with A/C in normal driving conditions. Would like to hear from those running SNIPER & A/C. Thanks!

    Download the Sniper EFI software and then you can see what it does.

    See the A/C IAC Kick function. If it's like the Terminator, HP & Dominator EFI, it's only a momentary increase in IAC.

    Are you looking for a momentary increase in IAC or a high idle function? The A/C "IAC Kick" function only produces a momentary increase in IAC, so the engine RPM doesn't dip down when the A/C is turned on (or in your case, electric fans). It works fine, but it does not increase & hold the idle RPM like a high idle function. Actually, the IAC Kick function is usually not necessary. It's typically a tuning issue with the Base Fuel Table. If you need a high idle function, it can be programmed in the EFI software Advanced ICF (1D Table, "Target Idle Speed Offset" Table Type, Switched Enable Activation) to use as a high idle switch.
    May God's grace bless you in the Lord Jesus Christ.
