Engine computer
How long does it take for the computer to learn when a change has taken place? I put on a CAI and my mileage has dropped significantly 2 MPG since installation. I hate to disconnect the battery to reset the computer.

are you sure the mileage change is not from your right foot? I've put two different CAI's on my truck and the result has been the same. Started with a S&B and immediately picked up some mpgs. Wasn't satisfied with the performance, so I now run the AF1 and picked up even more mpgs and a lot better throttle response. Thats without resetting the computer either time.

From what i have read (not sure on Ford... but true on Mercedes) the computer is in a "constant" learning state. there is no longer a need to disconnect the battery to trick the computer into "re-learning". This is only used in older models with some of the first "smart computers" or "learning comp's". Should be able to drive around and eventually your truck will figure itself out. but some people do report running too lean with certain CAI and from what i have seen, the only way to fix that... is custom tunes.

Those LTFT were specific to the old intake.

Zook: thanks for the heads up. Mercedes is apparently a little bit different (who knew 
). There is no need to disconnect the battery, the computer will figure it out and make its own adjustment. Or I use the scan tool and tell the computer we put CAI on.
So, I see your name all over the place and I gotta ask.. " i ride suzuki" you got a samurai? or are you refering to bikes?
