Can you hear a significant difference when you set the temp low? With my Super X pump (advanced timing via higher injection pressure) I can definitely hear the difference in timing rattle at low temperatures.

So who all has a potentiometer IAT? I would think that those people should be able to scroll the IAT through all of its settings (say 0 degrees F to 140 degrees F) and see what the timing sounds like. Has anybody tried that? Going down the highway with a load on (say a trailer on flat ground) and then scrolling the IAT should give you a pretty determinable sound.This has probably been covered already, but my thoughts are that we could use the potentiometer for an "on the fly" timing adjustment. When idling, set it at a high temp, retarding timing for no knock. Then, when up to cruising speed, set the temp low for timing advance and better mileage. I know that goes against the original premise of the IAT and fooling it to retard timing for better mileage, but the whole thing confuses me...

Time to revive this thread!! :)I was curious if anybody else had anymore deep thoughts on the subject. I've read about the IAT fooler, and other things to create different timing. My question is, when you change the IAT reading, does it create an entirely different timing curve for all boost and engine speeds, or does it basically take a pre-determined timing degree and add or subtract X degrees based on IAT? I was looking at a timing table that Moparman put up a while back and it would make sense that it reads RPM & MAP, determines a timing degree, then adds a static X degrees based on IAT. I could be way off though. Any ideas?
