When i try to log air temperature in evoscan i allways get wrong readings. My current rom version 96531706. I've searched, and no matter what combination of formula or request id I use, I always get a wrong number. I have the gm iat sensor wired into the maf plug, there's no motor in the car so I am testing the sensor against another, known accurate, sensor and my readings in evoscan are never accurate.

Can someone post there formula and request id for evoscan? And can someone post the scaling for the iat in the rom? Mine is the normal value that comes in v7 sd, I couldn't find anything that said to change it though.

 

Here are the scalings that I am using

whats your formula and channel for logging

 

The formula that I am using in evoscan 2.7 is 1.8*x-40 on request id 09. I am also logging this input through the fuel temp acd 0E.
