4.6l 2v PI tuning, how to just make it run?

[VhantaBlack98]

Finally decided I want to V8 swap. Decided on the 2v 4.6l. I know that in 99 it changed to Power Improved top end parts and tuning. However I have a 1998 base with the 5 speed manual and already know some things will need to be changed, I also know that the PI set up will require a tune to work in my car. So, what should I do and what would I need to allow PI to work in my chassis? Any recs on tuner software or any guidance on what values would need to be changed in a 1998 ecu for example? Not looking for any performance tuning, just want it to run like stock.

Are you using a V8 computer and harness?

Are you using a V8 computer and harness?

Yes. It will essentially be an entire 4.6 PI set up in a 1998 car. More or less I'm trying to figure out what harness mods i need to do, what all can stay the same, etc.

If you are using the entire 4.6 engine, harness and computer, there shouldn't be a reason to tune anything because it is all made for each other. The fuel pump/hander/tank should be different, but I don't know the connector difference.

The PATS system is whole-nother shenanigan fest.

Get the cluster, key/ignition and ecu from a donor car together and pats won’t be an issue. Your biggest issue is going to be finding a 98 ecu or changing your fuel system. 98 was a weird year, I don’t remember the specifics but ford used a combination of return and returnless fuel system in those cars, among other things. You might have to modify some wiring if using a 96-97 ecu to convert to a true return style fuel system.

I'd love to attempt helping you if you like shoot me a PM, can help with the PATS and any tune related issues if you are using the incorrect PCM...

Share as many details as possible, photos are helpful as well...
