Anybody have a clue as to what he meant?

 

Code on computer in engine bay must match the tune loaded into the tuner! They have to match or you car no startie!
Wow. I gotta shrink my sig! Good Lord!

 

I thought the Xcalibrator would download the Ford tune, so it has to know the correct code, right? How can that go awry and how can I avoid that happening?

 

It will download the factory tune but your codes on the computer must match the tuner! Just make sure you give your computer code when ordering and all should be ok! The only way the code would not match is if ford has reflashed your computer for some reason, giving it a different computer code.

 

Thanks!

Your sig looks much better now, BTW.

 

You guys dont removea couple of fusesbefore loading a tune?

 

Nope. No longer necessary, even though the directions say to do it....
