Installation and ordering

Have an experienced installer confirm the engine, transmission, connector layout and available inputs and outputs before ordering. Follow the model-specific Link installation manual and configure the ECU in PCLink. Check sensor calibration, trigger settings, fuel and ignition setup, and engine-protection limits before running the engine. A supplied startup map requires calibration for the actual engine.

Listed tuning features depend on the vehicle hardware, firmware, available I/O and configuration. Shared or repurposed channels cannot perform every listed function simultaneously.
