What is the difference between an IAW 59F M1 and a M7 ecu
I swapped them over on my car and it seems to still run ok

Was this a virgined ECU?

No, second hand - just swapped the transponder behind the brake peddle and strapped the replacement key to it to over ride the immobilizer
So you have fitted the ME7 decoder + ME7 ECU?

Yes. The one that came with the replacement ecu
The difference I think will be the hardware. i.e. Chipsets. The M1 is only fitted to the Schumacher and Abarth (sport pack). M7 is fitted to the other early MPI engined cars.
Puntos run the M7 also.

jims car mpi?
Only cars with ME1-7 Ecus are Euro 3 engines, ie MPI.
Early Seicento MPI cars, S, SX and Van have the ME7.
Some thing like 2002 on some started having the IAW 4AF.M1 which I think are the Euro 4 ones in the early stage?

my spi bits probably be no good to him then 
Yes, MF59 M1-7. Compatability depends on hardware and software. M3 and above may be able to use M3 and above code reader?
You would have to contact an ECU company for the specs..

Many thanks in clarifying the M/ME.
When you say "differences in the hardware and software", do you mean connectors and connector pin-out, and just general software upgrades?
I'm trying to establish if these can be transplanted from one fiat to another with a different "M" number variant?

Hardware as in chipsets/Microcontrollers. Both the ECU and Code Reader have to match from what I was told. I had an M3 model from a Punto unlocked to use as a test ECU. It runs my seicento ok, but with the injection light flashing.

Sorry for sounding thick, but what do you mean by the code reader? I thought the ECU IAW 59F was a standalone ECU?
The Punto ECU M2 seems to be more readily available than the the one for Seicento (M7) second hand and so rather interested in this.

The code reader is coded to the ECU and stores/reads the codes in the keys to allow the ECU to run.
If you get another ECU, you need the code reader and at least one key to make things work. Then you have to mess around with programing new keys to the same code as the donor key.
I would contact an ECU company for advice if your ECU is faulty.
