Interesting conversation here as I'm thinking of going down the PCM swapping path too with my '14 GT. I'm not very knowledgeable about this sort of thing and wondering if there are other things that may be affected by swapping back and forth, mileage recording for example?
Also having difficulty finding the right number: DR3A-12A650-ACE
In your situation I don't know. On these older cars mileage stays in the cluster. On my 99 bmw dash mileage had to match the pcm or the dash threw an error

ok so i basically need 3 new keys, 1 to match the original "tampered" with PCM and 2 for the new PCM coming in, then id be set to be able to swap the damn PCM every 2 years other than all the other mods i want or wanted to do....boy they really making it tough for us.

Technically you only need 1 key for each.

I just can't fathom going through the effort every two years of going back to stock and putting a pcm in and doing drive cycle.

I'd just get a non emissions rog and go from there.

Use the original let with the original pcm. Then the locksmith is only programming one set of keys.

No emissions as in old.

Classic car. Modern drivetrain

Have you considered hiding a piggyback ecu somewhere? Let it control fuel & timing and just leave it all installed all the time. As long as they don't do a super thorough underhood inspection, it should be doable.

Or, try one of the plug & play aftermarket ecus rather than futz around with 2 oem units.

That doesn't really help.
1) all the mods have to come off every 2 years to pass inspection.
2) the stock ecu will still need a tune or it will throw a fault for lack of emissions
3) There isn't a single standalone that is carb legal. So even if he goes that route, he's not going to pass and will have to resort to factory tuning every 2 years, and any time they receive a letter telling them to go see the state ref.

Here are your options in cali
1) leave it stock
2) mod with only carb approved mods
3) mod a car older tan 1975
4) take your mods off every 2 years. Pray you don't get called into the state ref, or have a cop inspect your mods.

In this scenario, the non CARB mods have to be reversed regardless.

Of course the ecu has to be reflashed by ford to clear the "this thing has been tampered with" code.

The piggyback to hijack fuel and spark is a way to easily go between the stock and modded tune, as long as the inspection doesn't catch it. The stock ecu won't know the difference.

Swapping ecus is a PITA. A one time install to solve all the problems and make tuning easier os a win win imo...provided they don't find it during inspection.

No PATS b.s., no swapping ecus, only need 1 key and 1 stock ecu.

That's assuming the inspector doesn't catch the piggy back and fail you.
Swapping ecu's is a pain how? It mounts in the kick panel.

Does this make you proud?
It doesn't make me anything. I don't live in that ****ing state.

But the point stands, someone tried to whoa is me about cali and say that they don't own their own car because they're told how they can mod them. They're just being dramatic.

The land of commies and socialists!
How about we get this thread back on track a little.

Has anyone considered buying their own PATS programmer? Maybe I am missing something here but it looks like the run roughly $120. I only ask because last I checked you're looking at paying roughly the same amount to have a locksmith program any new keys when swapping ECUs.

I originally planned on playing the swapping ECU game when I went stand alone. Takes me about 45 minutes from grabbing tools to putting them away. However, after about the 4th time pulling the ECU for other reasons I ditched that idea. I currently have other means to pass smog. But if the car gets sent to the ref station it'll suddenly get registered out state. It's not my daily and only comes out a few days a month.

OP, what's the eventual goal for the car? Are you thinking of making a beast or something that's just a little snappier than stock?

Thats correct sir, making her snappier but nothing crazy. I will drive it at least a couple times a week and enjoy her. Honestly if i can use the mods the car came with ill be happy at this point.
