The Marelli MM10JA is an engine control unit used in cars from makes such as Alfa Romeo. Prime Chiptuning always builds MM10JA files from the original read of the vehicle; generic files are not used.
Solutions offered for this ECU family include Stage 1 Remap, Pop & Bang and Stage 2 Remap. Which ones apply to your vehicle depends on the exact ECU variant, software version and engine; we check this from the read file before the work starts.
How a MM10JA remap is done
- The MM10JA is read by OBD, bench or boot depending on the variant, and the original software is backed up.
- The original file is modified for the vehicle, engine and requested solution; the checksum is corrected.
- The file is written, fault codes are checked and the vehicle is road tested.
- The original backup is kept, so the vehicle can be returned to factory software at any time.
