Programmable outputs? Just curious if there is any way to program the PCM (specifically the 0411 pcm from the f-body) to output a trigger under certain conditions.
Basically what I'm looking for is a switch to activate cutouts above a certain throttle % or RPM.
Anyone know if this is possible or a no go?
Thanks!

Don't know if the PCM can do all that my guess would be no.
A nitrous controller (window switch) does exactly that it activates a ground signal when user defined throttle % and RPM are met. The NOS Mini controller operates two separate stages so in theory it could activate two grounds, to two relays, to power the cutouts. Maybe one stage to open and the other to close. I'm not a electrical guru but maybe some of the smarter college nerds can chime in.
I use a Casper Electronics TPS breakout harness to avoid cutting my engine harness to send the TPS to the controller.
I have the controller hidden behind the trucks console. You can see the red & blue separate stage wires. The controller has a small remote LCD touch screen to change the parameters. The blue line under the tach shows where I have the RPM set to fire the NOS solenoids when it meets the TPS user defined input.

There are tables in my C5 that govern a shift light, and I assume they're in the F-body s well. My car didn't have a shift light, so the factory tune is set to turn it on at 12,800 RPM.
You might be able to use that output to govern your cutouts and turn them on at high RPM. But your cutouts would close when you press the clutch.
And it might not work at all if you have an automatic.
It might be possible to abuse the exhaust air pump output for this as well, but I don't see tables to control it.

You might be able to use the skip shift output to do it. I'm not sure if you can make it active on a automatic tune
