Software number different? Send the original file read with your own KESS, Autotuner or Flex. We transfer this Stage 1 onto your dump. Digital product — no refund after payment.

This page is a modified Stage 1 ECU file for the Alfa Romeo 147 2.0 TS 16V running Bosch M7.3.1. It is a professional remap — not a stock original flash and not a full ECU backup.

Match hardware 0261207725 and software 351952 / 55180798 before you write. If your sticker shows a different software number, do not force this file: send us your original read and we will transfer the Stage 1 changes onto it.

Workshops typically write this Alfa Romeo Stage 1 with Kess V2 after confirming the ECU sticker and keeping a restore file.

We can transfer this Stage 1 onto your original file

If your ECU is not on this exact software number, send us the original file read with your own tool (KESS, KTAG, Autotuner, Flex, PCMFlash, and similar). We will transfer the Stage 1 modifications onto that dump and return the modified file. Do not send a file that is already tuned unless you say so.

What this Alfa Romeo 147 Stage 1 file is

It is a daily-driver calibration for professional tuners and ECU workshops. Keep a known original on the bench before writing. A complete ECU image for cloning or brick recovery is a full backup — sold separately on request for €20. ECU flash repair after a failed write is €50.

Full backups and ECU flash repairs
