Does anyone know how to install a computer or system that would allow a leaner burn on a 2.2 ecotec. I am buying a saturn vue and thought that greater economy would be a timely and profitable project. I would actually like to be able to curve/Program for power and/or economy.

tire preasures can have a dramatic effect on economy. So can driving style if you shift into neutral on long downhills you will save gas, if you shift into neutral when stopped it saves gas, not gunning it away from every light will save gas. the money you spend on a computer to lean out your Vue will negate any savings it provides in mpg. I recommend staying up on your tire pressures and drive gently and you will see gains in economy.

these cars already hug 14.0-14.6:1 AFR almost all the time. How much leaner you want it?



I used to race cars, now I race myself.
