questions for the supernerds... (Digifiz & nitrous)

[Joe.Doty@lcnetwork.com (Joe Doty)]

I like it.  For added cool factor, extrapolate the resistance values vs.
intake air temps for your MAT sensor (is it a GM unit?).  That way you
could add a pot to adjust the amount of ignition retard.  Oooh, and then
you could wire a relay to interrupt the MAT signal when you get WOT (and
nitrous is presumably activated).

We aren't talking about the TEC II are we?  I figured it would be
capable of this sort of stuff already.

Bingo,
