Family and applications
Bosch ME7.6 petrol engine-management ECUs appear in General Motors applications including Opel and Vauxhall. Dimsport also lists ME7.6.1 and ME7.6.2 for the Fiat group, and I/O Terminal lists Fiat ME7.6.3. The family is therefore not exclusive to GM.
Choose ME7.6.1, ME7.6.2, ME7.6.3, ME7.6.4 or ME7.6.H4 below. H4 also appears as ME7.6H4 or ME76H4. These entries are a starting point, not an exhaustive vehicle fitment list.
Identification comes first
Different units and tool operations use different hardware or communication paths. A vehicle model, engine or family name alone does not identify the exact ECU, memory layout, calibration or recovery method. Start with ME7.6 identification and working record.
The ME7.1 and ME7.5 references on this wiki draw on Audi / VW examples; their addresses, map definitions and tool compatibility are not established for ME7.6.
