[QUOTE="BigJ, post: 101189, member: 62"] While the manual doesn't specifically say you should do this after any mod you make, its probably a good idea. Your ECU (Electronic Control Unit, sometimes called a PCM or Program Control Module... basically the thing that controls how your engine runs) is smart; it learns over time how to adjust itself to get best performance and economy, taking into account lots of things, including your driving style, habits, specific environment, fuel type and quality etc etc. It does all this by watching and tweaking itself, then watching again for new to see how the motor is running. All this is based on input and feedback from several sensors all over the truck and drivetrain. Sometimes when you change something (be it a new CAI, exhaust, fuel types, even environments), your ECU sees dramatically different input and feedback... aka 'stuff', for lack of a better term. It therefore needs to unlearn what its already learned about the old 'stuff', to then be able to relearn all about the new 'stuff'. You can speed this process along by resetting your ECU back to how it came from the factory. It can then start with a fresh slate, and learn your new 'stuff' right away. NOTE: If your mod did not involve disconnecting the battery, disconnect it for 45 minutes before performing the relearn process listed below. (If you don't clear the ECU by disconnecting the battery, I doubt the relearn would accomplish anything) From page 372 of the 2010 F150 Owners manual: [/QUOTE]
