I know that there are many different engine codes out there, but does each code result in different perfromance trends? Just curious because I don't see why they would run different codes if they didn't . . .

Is any one code better than another?

 

Hi Cougar Guy,

There are numerous reasons for different codes. Codes will vary based on which engine, which transmission, which gear ratio, which tire size, and so on, and these F-150's have numerous configuration choices mechanically, 3 engines, 3 transmiussions, 3 gear ratios & 3-4 tire sizes alone.

Now you will also see different codes for the exact same identical vehicle of the same model year, and in *those* cases, there generally isn't any difference in performance or power output, that isn't what that is about. It's generally just a very minor running update, usually some driveability or emissions issue that the driver will never be able to feel or notice. It doesn't make any difference in how the vehicle accelerates, but a different code places functions in different places, thus requiring us to do a matching code. Plus, we want to anyway, to take advantage of any aspect of any code that may ever come along. It's rare, but once in a blue moon happens.

Generally, there aren't "good" or "bad" codes for the F-150, which has 150-200+ different codes each model year alone.

 

Thanx Mike,

Informative as ever

 

You're very welcome, anytime! I had to go back and correct about a bazillion typos in that last post, including not spelling your screen name right, sorry 'bout that!

 

Hey, no prob Mike!
