Is there any difference between a 2003 and 2004 computer in the calibration, the A/F or in the fuel tables? Will either computer be interchangeable in any Lightnings 1999-2004 as long as they have a 90mm MAF?

Thank you in advance for your input.

as far as I know, there is absolutely no changes between 03 and 04 cosmetically, mechanically, or electrically, except the addition of silver paint

Yep, that's it, just the addition of silver...

 

I think you just needs to get the "paps" or "pats" (something like that)code flashed for the key. Sal did it for me once.

 

Yep...you need either a 'paps'mear or a 'PATS' reflash.
