Run good enough fuel with the nitrous and do it. Ill run a stand alone cell for my fuel side when I do nitrous just for that reason.

It was literally the first time it had ever been sprayed. Kind of a trial and error type thing while at the track.

This is true, we hadn't verified my IAT trick either, so we needed some sort of timing retard to see if it was working

Whats your IAT trick? You spraying pre iat and having it pull timing from the cold rather then add it?

There is a relay in the sensor. When the nitrous hits the kit also sends a surge of power to the sensor and makes the PCM think IAT's dropped to -40. in the -40 column we took out 3*.

It's not something we could use boosted... or at least not something I would want to do boosted in case there is some sort of IAT spike we need to be mindful of.

Kind of. When the nitrous solenoid is activated, that same signal activates the IAT trick relay, which essentially unplugs the IAT sensor. Because there is no signal, the PCM defaults to the lowest column (no signal is the same as 0v) which is -40F.

I've heard of that being done before and it seems to work very well, as long as the relay doesn't fail
