Description
A Stage 1 tuned calibration for the Magneti Marelli MJD 8F3.L1 in the Fiat Linea. It fits hardware 55266289 with software 3050L125; both must match your unit. The base read came via IO TERMINAL.
This is a modified map, not a stock file. For off-road, export or motorsport use only; it is not road-legal in the EU/UK. Keep your own original read so the car can go back to standard, and check that the software number 3050L125 matches before writing.
Same numbers in other versions: the stock 55266289 3050L125 file and the immo off version. More in all MJD 8F3.L1 files.
FIAT LINEA MJD 8F3.L1 55266289 3050L125 STAGE1 TUNED is a chip tuning (stage 1 remap) file for the Fiat LINEA fitted with the MJD 8F3.L1 engine control unit. It matches hardware number 55266289 and software number 3050L125. The file was read with IO TERMINAL and is supplied exactly as read from the unit, byte for byte.
Typical use: improving power and torque while keeping the engine within safe factory limits. Before writing the file, confirm that the hardware and software numbers printed on your ECU label match the numbers above; writing a file to a unit with different numbers can damage the ECU.
After secure checkout the file is available for instant download from your AutoECUFile account, and it stays there for later downloads. Need another version of 3050L125, or a file that is not listed? Send us a file request and we will source it for you.
