PATS is not a bad thing, in fact it is a deterrent. There are concerns about PATS for loads of reasons when modifying these cars or doing a modular engine swap.
PATS does not affect the operation of the engine, it just prevents it from being utilized without the correct key.
For those guys using the stock fox steering columns you can always remove the transceiver key coil from the SN 95 steering column and locate it in a remote position under the dash if you like, however there is a proximity issue with the key to the coil/transceiver, which is easily overcome.
Of course there are programmers out there that can eliminate PATS altogether, but if your PCM dumps and you are miles away from home, this could cause an issue.
I think PATS is a pretty good system, i have spoken to many people in the past and tried to bypass the PATS system with no luck, but that’s ok, it proves that it works.
I know some people don’t want three keys to operate their cars, one for the FOX doors, one for the SN95 ignition switch, and one for the trunk.
when i did my first engine & dash swap in my 1980 Fairmont, i had loads of issues to overcome. I had to fit fuel injection to the car, fit a 5.o add a 93 dashboard, add a parking brake in the center console , had to modify/make the loom, add a 2000 Mustang frt suspension etc, it all came out ok.
Now i am getting ready doing the 4.6 swap, pats is the last thing on my mind, i actually want PATS. Then again i have other issues to overcome, trying to get the dash cut without destroying it, repairing the wiring loom, trying to get the wiring to fit, drilling more holes in the car, repairing the a/c etc.
I suppose what it boils down to is that everyone has issues about something, but truthfully PATS is passive, and doesn’t cause troubles so long as you have the key/s.
There are no moving parts to wear-out, usually the only issue arrives when the keys are not present or the transceiver ring breaks, however you will need an IDS tester from Ford to diagnose it if it ever goes wrong.
Unfortunately, i have no knowledge as how to delete it altogether, but i can diagnose & repair them if i have a code to work with.
As stated previous, i have tried various ways to bypass it, i know there are transceivers out there that will eliminate the key for the system, but i personally have not “deleted PATS from the PCM, but i feel it would be something nice to know how to do, i suppose it can be done with a high-end aftermarket programmer???
