You guys already knew this, but i found this out the other night. If you take the (ATS) Air temp. Sensor out of the intake and rewire, move it where it gets more cold air, it adjust your timing and adds more fuel. I guess SLP also makes an actual part for that so you dont have to cut wires. After you do that undo your battery for 15-20sec then start it and run it. When you put into drive your car will kick big time (mine did). Then drive it them it should adjust. I dont know how big of again it will do, but why not. Sorry if its a repost Im new

This is old news. Also RKSport use to sell a IAT sensor that reads 34.6, or 36.4 degrees at all times. More fuel is not always better. GM cars usually run rich from the factory so you are adding more fuel (which might not be needed), and could lose power.
Without a wideband sensor, and other info you will never know.
I recently did some testing on a 99 Z24 auto. The owner has the RKSport IAT. I have dataloags showing the temp readings. If people are interested I will see about getting them load on the net. We went and made some runs with the car recording timing, fuel etc.... We then put a stock IAT in that now reads like it should (hotter than the RK one). With a stock IAT we actually saw 1-2 degrees more timing advance over the RK IAT. This was also done within a few minutes of each other, so the computer had not fully adjusted to the new sensor, nor did we disconnect the battery either. I would go back to the IAT in the stock location.

Also, that "kick" is because the auto tranny act up when the IAC is not working properly. If you want to get better reading, bring it closer to the tb and thaT's all.
