So I recently bought this 96 mustang 4.6l. the pats system went out of it, I figured Instead of buying a new module and getting it programmed I would swap out the ECU with either one with the pats deleted or a different ECU. I've been doing some research and some people have said a 96 Grand Marquis ecu would work, also some people said the p71 ECU out of a crown Vic police interceptor would work, and gain extra power. As long as the speedometer works, I'd be happy. Anyone have any thoughts that could help me out? It is a manual and the ECU is eec-v hookup.
Resolved 96 crown Vic ECU in a mustang gt
- Thread starter QuickDibbles
- Start date
No one had anything to put forth so I bought an ECU out of a 96 crown Vic police interceptor. It plugs in and runs just fine. Everything works, speedometer, headlights, etc.. they're cheaper than a mustang ecu and as far as I can tell there isn't a decrease in power, if anything there should be an increase with the police tune. So I guess I'll document it since I was never able to find any information. An older PI ECU works in the older mustangs, try to match the year.

now i can hopefully expect to receive the shaft
Glad it worked out for you. You should run codes and see if you get the ‘working correctly’ codes that should appear if all is well.
Also throw up part numbers of the ECU, could be beneficial for others who need to do something similar.

Will those codes appear with just a regular scanner or would I need a more advanced one?
I believe only 96-2000 interceptors had no pats. There's a few catch codes I've been told but I know for sure that XXL4 is a police interceptor code. VPX3 is one of the common civilian catch codes. Also at the end of your code, the long one, there will be a two letter code. CE or CF is the police interceptors as far as I am aware. Ones that that with A like AE or AF are civilian. If you look at a crown Vic forum you can get a lot more information than what I know.

You need one of the dumbest, cheapest scanners on planet Earth:
One thing does not equal the other. A "police tune" could be nothing more than retarding timing at idle to make it run cooler.
Most 'cop mods' are for reliability and/or meet requirements for GOV/Fleet specific vehicles.
