Better MPG for just about no money. Options

Take a ristor that has about a .2k ohm resistance and plug it in to the plug that goes to the IAT sensor. the car will use less fuel. and still read a temperature that is in spec and wont throw a code. it worked for me. but since it leans out the fuel dont drive very hard it could be hard on the engine.

it does work. Think about what the IAT is and what it is there for. The IAT is basicaly a resistor that changes resistance as the temperature changes (which it shouldnt change too much once the car is warmed up, for me normally the air is about 87 ferenheit) the car takes this reading from the IAT and changes the fuel mixture based on the temp. Cold air is more dense and needs more fuel to burn more completely, hot air is less dence and uses less fuel. if you trick the reading of that IAT sensor and say make it run as if the IAT is 120F (still an acceptable reading) the car will use less fuel and will get beter mpg. when i messed with mine i used a potenciometer , or a variable resistor, and a scan tool to find the exact temp i wanted my car to read. This does work. ive driven around all week on a quarter tank of gas.
