The hardest part of installing the G-Force Chip on
my 1997 Jeep Wrangler was locating the Intake Air Temperature sensor. The engine has several sensors that look alike, and tying into the wrong one would
probably cause unpredictable results. (click here for IAT location PDF on Wrangler 2.5L engine).
The next thing I had to do was extend the wires (there are 2 wires) from the unit, because the wires that came with the unit would not reach from the IAT sensor to the inside left fender where I wanted to mount it. Instead of splicing wires, I opened the unit (3 screws), pulled out the circuit board (which is on rails inside the case), and soldered new wires to it,
then put it back together.
The next thing I did before installing this unit was to obtain a wide piece of Industrial Velcro® to use for mounting the unit instead of the small strip of double-sided tape supplied with it.
The small piece of tape would get wet and hot, and eventually, I
figured, the thing would be dangling in the engine compartment by the
After removing the air intake system to get to the Intake Air Temperature Sensor (IAT) to hook up this Performance Chip, I replaced the engine air cleaner with a
Spectre Performance Filter while I was at it.
The improvement in engine performance was immediately apparent. As I drove a few miles, the G-Force chip /
Spectre Performance Filter combination revealed another advantage – approximately 15% average gas mileage improvement.
