Just a couple of questions on ECUs

I hear there are coded version (16F) and a non coded version from earlier models (6F) would it be possible to swap a coded ECU for a non coded one?

Is it possible to swap two coded ECUs over then swap the code box under the ignition barrel. Then remove the code chips from the donor ECUs keys and place them in the old keys as to save changing the ignition barrels and locks etc?

Is it possible to swap coded two ECUs then swap the code chips over (as one would insert a mckritch chip) to save swapping anything else?

Cheers

Looks more like three to me

Yes. You can even run an 899 non coded one, although the rev counter won't work in all cars.

Everything works up to the point of getting the code chip out of the keys. I think they are moulded in.

Think that should be possible.

My blue keys have little grey panels on the back of them. If you open them they have little black, what look like magnets, but i presume are the code chips. So if that were the case. The my second question/idea should work?

I guess. On the red keys the chip looks more like a transistor.

Easy way to test (I imagine you want to just swap the ignition barrel) is to tape the keys together (old and new) or just place the old one by the transponder.

You might find that Timsons or suchlike can read the code on the old key and transfer it to the new (which would save risking damaging the other one).

All Fiat non-remote keys are moulded around the transponder, all aftermarket have removable transponders. Either way any key can be copied by local key cutters.
And yes the principle will work ok.

Found a red key with removable chip today, but the blue key for the same car has no access to the chip..

Forgot to say all master keys have removable chips.
