OK, as we know, some cars' AC doesn't cooperate well with the PowerFC. One workaround is to bypass the ECU's control of the AC - this does work, but it will leave the AC engaged at high RPM or load unless you manually turn it off. This is a Bad Thing for the AC compressor, not to mention it robs power.

Found this from Zeitronix -

Awful name, though .

Basically, it wires into the TPS signal down by the ECU and splices into the AC signal. At more than 60% throttle, the AC is switched off, and will stay off for 6 more seconds once the throttle returns below 60%. This basically emulates the control of the AC that the ECU has.

The price is really reasonable ($55) and it's VERY possible that it will work. Worth trying if you've had AC problems from the get-go, or haven't had luck with cleaning the fan switch.

Any thoughts?

I am not sure if this will work because if there is no turning on of the A/C to start with how will it act ?
