Better MPG for just about no money. Options

[TannerEsser]

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.

with no change in the engine or electronics my mpgs has ranged from 21mpg to 34mpg.

mainly how hard i drive, ac usage, ambient temp, traffic, average speed, etc.

how to get better mpg...
drive slower.
replace your o2 sensor
get a free flowing intake/exhaust
do a full tune up
lower your car, sideskirts, etc
skinnier or less grippy tire (negligible)


do those and i cam almost promise you will gain 5-10 mpg, depending on where you started

but all that cost a lot of money....... but a potentiometer is like 3 bucks haha i have noticed a difference in mpg on low resistance and a difference in power at a higher resistance. it reads 55degrees F for higher resistance and 120 for lower resistance(122 to be exact haha). but i don't care to much i just thought it was a fun little trick to try out. my tech instructor has one on his stock eliminator car. he uses it so he gets better mpg when pitting and not racing and docking around idk but he uses one lol.
