Why would PATS care if the engine changed???


I'll even give you the benefit of the doubt (don't all die folks ) and say that "maybe" you were thinking the biggest problem would be the computer program required to run a 6 cylinder Duratec vs a 4 cylinder Zetec would have to be a different strategy. This in turn causing the PATS module to not recognize the new strategy and give a no start condition.

However... (you all knew it was coming )

When you get this new "custom tuned" strategy you can either have PATS reprogrammed or just turn it off altogether.



I based my guess on PATS being the most difficult problem to solve on the article in the first FocusFanatic Magazine on the Focus that had the 2003 Mustang SVT drivetrain installed. That article indicated that the Focus interfaced the Instrument Cluster with the ECM and the Key. They had a guy who knew the system well solve the problem but the "read between the lines" message seemed like this was the toughest part to solve.

Again, I'm just curious if Bnoon ever managed to do the duratec swap. No serious intentions here on embarking on such a project.
