Scope
This index covers selected M3 designations relevant to Intel MCS-96 / 8xC196 research. The processor evidence belongs to specific inspected or researched units; the 3-series label alone does not establish the microcontroller, memory or software of every ECU.
A researcher documents an M3.8.2 development unit using an 87C196KR and an external-flash adapter. The adapter is a modification, not evidence that all M3.8.2 units have that memory layout. EcuProg7: MCS96 research project. Community examination of an M3.8.3 unit also identifies an 87C196-family processor. Nefarious Motorsports: M3.8.3 discussion.
Research tooling targets M3.2 and M3.8 binaries using MCS-96 tools, but does not identify each supported ECU's physical processor. An M3.3.1 researcher reports an 80196-family processor. These references are leads, not verification of every hardware revision. EcuProg7: M3.2/M3.8 research project; TunerPro: M3.3.1 research.
Identify the exact unit
Record Bosch and vehicle-manufacturer part numbers, hardware and software IDs, engine and vehicle, and the processor marking on the actual board. Do not infer that M3.2, M3.8.2 and M3.8.3 have identical connectors, memory or programming methods. The pages below distinguish direct observations from unverified candidates.
