For all you guy controlling your nitrous with a FJO mini controller I need your advice.

I wired input #2 of the controller to my TPS switch, and not only is my nitrous not working I am throwing a tps code when the system is armed at wide open throttle.

I followed the instructions and programed the tps signal into the controller by holding the tps learn button until the lights quit blinking and put the pettle to the floor twice. I verified that it worked by seing that the light only comes on at wide open throttle, so it should work. Could it be that I set this while the car was in acc mode not running, but it should still have the same tps voltage? Could the controller be pulling the tps voltage down far enough to through a code and not trigger the nitrous? Any Ideas?

I am about to just hook up a wide open switch on the trottle body.

 

the TPS activation is input #1...the red/white wire
Input #2 (solid red)...is a secondary arm/disarm signal wire...IE Trans brake or clutch switch deactivation
