The computer in the newer Jeeps can be tuned to do a number of things from increase in MPG to correcting the speedometer after installing new tires. Depending on the make, model and year of Jeep, you can accomplish different goals using coders or "piggy back" systems. You can also send your computer out to be flashed or coded for any modifications and upgrades you've done to make sure you are getting the most power and best fuel economy out of your Jeep engine.

Warning: be wary of "to good to be true" chips that announce super MPG increases. There are many scams out there so if it's too good to be true it probably is... be an informed consumer.
