Bosch M7 Ecu Pinout Portable < 2024 >

Since Bosch does not publicly release official schematics for their ECU internals, a "solid piece" on the Bosch M7 ECU pinout requires aggregating the industry-standard pin definitions used by tuners and wiring harness manufacturers.

• The ECU grounds A11 (fuel pump relay) only when it sees crankshaft signal. If pump runs with ignition ON but engine off, the relay driver transistor inside ECU may be shorted.

• TPS: ~0.4–1.0 V closed, ~4.0–4.8 V at wide open (depends on sensor)
• MAP: atmospheric at idle ~1.0 bar (or ~100 kPa) converted to ~4–5 V depending on sensor; vacuum lowers voltage
• CLT/ECT/IAT (NTC): 0–5 V inverse to temperature; compare to expected resistances
• CKP: VR sensor: AC sine wave ~0.2–6 V p-p depending on RPM; hall: 0/5 V square
• O2 narrowband: toggles between ~0.1–0.9 V around stoichiometric when warmed
• Injector drivers: switched to ground (low-side) by ECU; see pulse widths ms range
