Main Engine Sensors
The Main Engine Sensors are required for correct operation of the ECU.
The engine RPM is derived from the REF trigger sensor.
The SYNC trigger sensor is required for Sequential Injection or Multi Coil
Ignition Systems.
The Throttle Position, Manifold Pressure, Air Temp and Engine Temp are
used as inputs to the various calibration tables.
Optional Sensors
The Optional Sensors are not required for basic operation of the ECU.
The Digital Inputs may be used for wheel speed measurement or to activate
functions such as Dual RPM Limit, or Nitrous. (Advanced Tuning Only)
The Lambda Inputs may be used for wide band air fuel ratio measurement or
wide band or narrow band closed loop lambda control.
The other inputs may be used for data logging or for special calibration
features.
