ac auto off

[dsmturboawd]

just an idea, is there a way we could rig the ac so it automatically turns off when you floor it or something? i cant tell you how many times ive raced with the ac on, completely forgeting about it. or maybe it would be easier to rig it so when 4000rpms hit, the ac turns off or something..

The 2G already does shut off the AC compressor at WOT. You could get a chip for the ECU if you wanted it to shut off above a certain RPM. TMOs does it, and I think DSMLink does as well.

Stock it's WOT and 5500rpms. At least on my 99.

Or. if your familiar with electronics and your ecm schematics, & if you can get a voltage input/output from a wot signal, you could wire up a relay to open and stop your a/c from coming on.

There used to be a vacuum switch called a Passmaster which would open when you lost vacuum, meant for AC cutoff. I have no idea if they're still around or not.

or you can just use a hobbs switch for some very low psi (say, 2 or 4 psi). when the desired pressure is reached, the hobbs switch can send the signal to turn off the a/c.

TCAC (Throttle Controlled Air Conditioner), designed specifically for 1G DSM and GVR4. 1G ECU doesn't switch A/C off like 2G one at higher RPM.

yeah most new ac systems do this.
