Son ECU
Bosch M1.5.5 — the earlier Motronic controller of the Twin Spark range. Engine-bay mounted.
Comment il se lit
An older platform, so plan around your tool: some read it through the OBD port, many expect bench work. The tool’s vehicle list for your exact engine is the authority.
Ce que couvrent Stage 1 et Stage 1+
Stage 1 on this car is a documented recalibration of the factory maps for a mechanically standard example — built from your own original file and approved by a human tuner before you can download it.
Stage 1+ is the declared-setup version: your fuel and supporting hardware are written into a per-ECU contract together with the expected gains for that combination. The stage guide walks through choosing between them.
