I'm looking for a way to manually increase the idle setting of my 350 tbi.

Installed a new engine harness, removed all electronics not necessary to the operation of the motor. One option I'm looking at is the AC switch. Throwing the AC to ecu wire on a toggle switch when toggled on it throes the signal to the ecu. Is it possible to program the chip to increase the "AC" idle to let's say 950 rpm's?

Thanks
