Okay this may answer all Mitsubishi motors IAT location questions as my 2000 montero sport and 2003 eclipse GTS have the same intake mass air / iat sensors.
Using a 2.2K resistor I am supposed to be able to trick the ECU into thinking the car is getting more air than it is by showing a false low temp reading, thus adding more fuel and producing more power. Now I need to know which of the 6 or 7 wires going into the combination mass air sensor and IAT sensor plug are used for the IAT.
I ran a continuity test and found what I thought to be the IAT sensors in pins 2 and 3 but when connected to the resistor the check engine light comes on and the car burns 2-3 times as much gas (real MPG less than 10 from over 24 origionally) and idles unevenly (goes from 750 to 1400 about 2 times a second). I had read that it would affect mileage but only by a point or 2, not 8 gallons for 65 miles!!!
After some pondering I thought that perhaps these may be normal side effects of this afro-engineering method of increasing HP... anyone know?
Also, if anyone knows any good referneces for tuning a 2003 Eclipse GTS let me know, I need the inspiration.
Tks,
