Hi everyone
I have to perform STAGE 1 for FIAT BRAVO 1.4 MULTIAIR 140HP 104KW ECU Marelli 8GMF, since I'm not familiar with this ECU, I decide to send files to a professional chiptuner. I have sent files to 2 very well known chiptuners also here on the forum, no one has been able to fine-tune this file.
ECU was read with OFFICIAL TRANSDATA MASTER.
I send the file to the first chiptuner, I try to write the file, and transdata always returns an error, as if there are more areas in the file, which transdata does not recognize and does not allow writing.
According to chiptuner, I write files, the instrument panel turns on the ABS warning light, I diagnose and find 2 DTCs in ABS, DTC C1881 and U1701, I rewrite the original file and immediately everything returns to work without warning lights and without DTCs.
Both chiptuners failed with this file.
Can you help me with this ECU?

I attach data and original ECU file
