The best way to do the resistor trick is to add a POT rather than a fixed resistance resistor and we should never see the IAT signal cut. Not sure I answered anything, lol, just put some stuff out there. I have tried using the power adder vs IAT fuel multiplier table to add fuel by targeting some pretty low temps with the dry, and never saw an increase in timing. Try it n/a logging and see if you get any added timing? I can't think of a "Bias Table" off hand, but don't have my HP Tuner handy. good luck and if you get any insight yourself be sure to let us know.

Robert - yes I'm using a Potentiometer on my car, 1-1k i believe, but I'm targetting the middle of 1 column. I'm targetting 154*, that way its 4/5* away from breaking into the next column of cells should it move even a little bit.
Its really the BIAS table I'm curious about, the IAT base/multiplier + low octane/high octane maps I'm pretty familiar with.
I'll talk to my friend again about this BIAS table he is talking about, but as simply as i can put it, it is its own stand alone table that directs timing based on IAT & coolent temps i believe. Apparently it is tuneable, but for now thats why i did NOT go to the very end of the IAT spectrem (low -38*, or high ~240*) as i assume the higher/lower you go the more aggressive it will correct timing. Besides The 158* column is realisticlly out of the range of IAT's that I'd ever see even during a hot summer day here in TX anyway...
Whatever i find out I will report back!
