I've heard of people unplugging the IAT and replacing it with a resistor that gives the computer a value of 58 degrees in order to get more timing advance. But it's tricky because if the actual air temp is much higher this will cause knock and the computer will just pull the added timing right back out. There isn't a lot to be gained here. The only way I can see this chip being worth anything is if it can modify the IAT value to stay a set amount below actual temperature, as opposed to simply feeding a fixed value like the resistor trick. Still probably not worth it though.
