So I loaded up the COS and populated all the required tables. Pinned a wire into the pcm and tested it to verify it detects ethanol in the system when 12v applied.

My question is can i use my nitrous controller to send 12v on that wire when it activates, or will the pcm not correct quickly enough? If that is a issue then ill just wire it to the nitrous arm switch.

I ask because i already have had everything wired for the window switch to activate something to pull timing. But if the ecm cant correct instantly, Ill have to run new wiring through the dash to my arm switch on the opposite side of the truck. Huge PITA and would rather not (but will if thats the best way to do it)

TIA
