Pins C-19 to C-34 do not exist on a standard 34-pin housing — the 34-pin is arranged 2x17, but I map common expansion: suzuki k6a engine ecu pinout high quality

Critical timing inputs from the Crankshaft Position (CKP) and Camshaft Position (CMP) sensors. | Pin | Wire Color | Function |

| Sensor | Signal Pin | Voltage | |--------|------------|---------| | TPS idle | A7 | 0.5–0.7V | | TPS WOT | A7 | 4.2–4.8V | | MAP (engine off) | A4 | 4.0–4.2V (sea level) | | ECT (cold) | A6 | 2.5–3.0V | | IAT (ambient) | A5 | 2.0–2.5V | We will focus on the 64-pin Denso ECU

For those interested in exploring the Suzuki K6A engine ECU pinout, here is a sample of the documentation Alex created:

Pinouts vary slightly between the , Alto Works (HA11S) , and Cappuccino (EA11R) . However, the core 64-pin or 72-pin connector architecture is largely consistent. We will focus on the 64-pin Denso ECU , which is the most widely swapped and tuned variant.
