ECU Ford Mustang 3,7 2012 programing / clone

[rootspk]

Hi guys

I'm having a problem with the ECU in my Mustang. There's a short circuit in the coils. I'm wondering whether to repair it or buy a new ECU and program it.
But here's the question: how?
I have Forscan, but I don't know if I can program the ECU with it to make a copy of it.
I was thinking about making a copy of the ECU with Forscan (if possible), swapping the ECU, and then programming the new one with the data from the old ECU. But as I mentioned, I don't know if that can be done with Forscan. Perhaps I need a different tool? If it were possible, another question arises: each ECU has its own serial number. Shouldn't it be added with a new one after the replacement?

I assume you mean that you have determined one or more ignition coils are failing repeatedly and you suspect the PCM coil driver? I assume you have checked and performed all the Ford Pin point tests for this problem and the PCM is the actual culprit?

PCM Programming with FORScan will require version 2.4.21 and the firmware cannot be copied with FORScan but can probably program that PCM if all Firmware and AsBuilt files are downloaded from Motorcraft/forsdserviceinfo.com!

Fords IDS can do this copy and reload but requires a Ford VCM2 adapter! Ford FJDS can also do this but requires a J2534 PASSthru adapter and both would require at least a 72 hr Ford license!

If this is one of the older PCM's it will require an adapter with FEPS capability such as the vLinker FS or a J2534 PassThru adapter!

If you can find a new PCM (Which is unlikely being over ten years old) it would be blank and would need the full firmware update performed!
A Rebuilt PCM or sending in your PCM (Flagship One as one example) for rebuild would be an option!

A Used PCM is possible and would require Vehicle ID block and FIrmware programming to change Vehicle IDBlock settings such as Vin Number, Tire size and drive line and cruse control settings or in later PCMs(From about late 2012 approx) and up these are in AsBuilt settings! Later Asbuilt can be saved and reloaded with FORScan!

The only "Serial" Number that matters is the vehicle VIN number and that the PCM part number XXXX-12A650-XX matches the the vehicle line! In your case CR3A-12A650-BA to CR3A-12A650-HC see this link for the PCM Part numbers that have been used in your particular vehicle: https://www.fordserviceinfo.com/Reprogr ... alibration!

What you are asking is not a simple process and has been known to render vehicles into expensive driveway ornaments eventually being towed to a dealer!

Just so you are aware of the dangers!

One of the coils blew, and another new one installed in the same cylinder blew as well. After checking, it turned out that there was a constant voltage of 12V on cylinder 1. It didn't disappear when the ignition was turned on—it was constant.
After disconnecting the coil on cylinder 1, the engine started. The wiring was checked, and there were no short circuits. After connecting the connector to the ECU, a short circuit appeared.

Yes, the ECU is faulty. The car has been in the service center for two weeks, but we don't have service manuals, even at authorized Ford service centers for the fifth generation up to 2014—they simply don't have them, they don't even have part numbers.
I don't know what ECU model it is because the car is in the shop, but this has been going on for a long time, and I'm not sure if I'll have to do it myself—that's why I asked about cloning it from a donor.

Another solution is to replace the damaged components. The ECU can be read, so I assume the system itself is fine. The MOSFETs are most likely damaged, but that's just a guess. I don't have the ECU at home, but it was sent from the repair shop to another shop that specializes in electronics. However, the second shop doesn't have my license.

Does anyone have a schematic or board view of these ECUs, or a list of parts that can fail in the ECU?
