I am running code 2.883 and I am trying to use the fidle pin as a fan controller. I have the idle control set at none and when I go to the spare output settings and enable the filde pin and set collant > 20 with hysteresis of 10, power on value of 0, trigger value of 1 the fan does not turn on, I can set these number to be anything (coolant >100, <20,<100, and all combination of power on value and trigger value) with not luck. I know the circuit works because when I power on uS the fan turn on for 3 sec then will not turn on again with the engine running or not.
any ideas? is there another setting I am missing?
I have also tried the same thing with the accel LED and the warmup LED with the same outcome.

I remember looking at this problem a few weeks ago and couldn't find anything wrong. I was able to move rpm and coolant up and down and the leds would light/ not light. If you post your msq I will try it.

Here is my MSQ

I tried your msq by enabling the fidle spare port. I then selected coolant > 150 with 10 deg hysteresis, burned the changes, cycled power and everything works perfectly on the stim. I tun the clt knob to > 150 and the fidle led comes on, turn it back to 140 and it goes out. Very repeatable. Is it possible you never burned the change and cycled power ? The reason is that the processor sets up the spare ports at startup and thereafter no longer does any setup. This is by design because you don't want to be changing port pins while driving, plus it's a waste of cpu time to be checking for a configuration in the main loop. I believe you can change the threshold and hysteresis on the fly because that is a tuning variable, but the designation as a spare port is a configuration variable.

ok I understand, I am not sure if I burnt it I think I did, but never the less I do not think I did uS power cycle between settings change. I will try again and update you, thank for the help.
