This decoder is based on the K6a decoder on a 3 cylinder engine with a trigger pattern on the camshaft consisting on 6+1 teeth.
provides specific decoder settings for the K6A's 6+1 tooth camshaft trigger pattern. Model Specifics
I traced the Malaysian car’s problem to pin (Main Relay control). The previous shop had swapped an ECU from a naturally aspirated K6A (33920-54G10) into a turbo car. The NA ECU didn’t have the main relay driver enabled on the same pin — different firmware mapping. suzuki k6a engine ecu pinout better
: For those swapping the K6A into other chassis (like the Suzuki Mehran), a clear pinout allows for the integration of factory clusters, ensuring speedometers and warning lights function as intended Tuning Potential
To ensure you have the "better" or most accurate diagram for your specific project, consult these repositories: This decoder is based on the K6a decoder
: Pinouts differ between the K6A-YH6 (industrial/gasoline), K6A Turbo , and VVT models. Always verify the part number on your ECU (e.g., Denso 33920 series) before final wiring.
Instead of relying on generic OBD-II codes (which are primitive on K6A), back-probe the ECU pins: The previous shop had swapped an ECU from
from 1994 to 2018. Its Engine Control Unit (ECU) manages critical functions like fuel injection and ignition. Because the engine exists in both naturally aspirated and turbocharged versions, pinout configurations can vary significantly depending on the specific model and production year.
