Triggers

Trigger inputs

Trigger inputs are the single most important input to the ECU. This input gives the ECU information about the current crankshaft and camshaft position as well as the engine phase.

Please route the wires for the trigger inputs away from high EMI sources (spark plug wires) and use a shielded cable.
