Fiat 500 1.2 8 Map Location

Postby polo35580 » Fri Oct 16, 2026 8:31 pm

Hi everyone.

I'm looking for the map location of my Fiat 500 1.2 with a Marelli IAW5SFHW405 software 8708S44.

Here the ECU informations:
Fiat Hardware Number: 51875964
Marelli Hardware Number: IAW5SFHW405
Marelli Software Number: 8708S44
Fiat Identifacation Number: 5SF9MS
Fiat Iso Code: 0D07F808E9

And the dump extracted with MPPS v18.

My goal is to mod it for E85.
I already found some maps with ECM but I'm not sure for the ColdStart and Lambda trims.
If any one has a damos / mappack for this ECU and can send it to me or help me to find those maps it will be greatly appreciated.

Best regards
