When the ECU grounds pin 86, the relay closes and sends power from pin 30 to your fuel pump (pin 87). Step 4: Shield the RPM Signals
Verify that engine block-to-chassis ground straps are clean and secure. MAP sensor or Coolant sensor wired incorrectly.
If you are removing non-essential circuits (e.g., automated AC requests), use a pin extraction tool to gently lift the plastic retaining tang inside the ECU connector face and pull the wire out from the back. Do not cut them flush at the plug; pulling the pin completely leaves an empty slot for a cleaner finish. Step 2: Optimizing Ground Paths
The K6A uses a 6+1 tooth trigger pattern on the camshaft, which is critical for aftermarket ECUs like Speeduino to understand timing. suzuki k6a engine ecu pinout repack

The Suzuki K6A engine evolved over a production run spanning more than two decades. Because of this, it features several different ECU configurations. The most common variants found in the enthusiast and swap community include:
