MoTeC Overview 7
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 Lambda Inputs may be used for wideband air fuel ratio measurement or
wideband or narrow band closed loop lambda control.
The Digital Inputs may be used for wheel speed measurement or to activate
functions such as Dual RPM Limit, or Nitrous.
The other inputs may be used for data logging (eg. Exhaust Gas Temp, Gear
Box Temp, Driver Boost adjustment etc) or for special calibration features.
Fuel Injector Outputs
M400
Up to four injectors may be driven fully sequentially including very low ohm
types (0.5 ohms).
M600
Up to six injectors may be driven fully sequentially including very low ohm
types (0.5 ohms).
M800 & M880
Up to twelve injectors may be driven fully sequentially by the ECU if the
injectors are high resistance types (12 ohms or greater), otherwise up to eight
injectors may be driven fully sequentially including very low ohm types (0.5
ohms).
Four of the Ignition Outputs are used for full sequential 12 cylinder
operation.
Twelve cylinder engines may also be driven as six groups of 2 injectors
which leaves all six Ignition outputs available for wasted spark ignition.
Outputs not used for Fuel Injection may be used as Auxiliary Outputs.
Ignition Outputs
The Ignition Outputs may be used to drive many different types of ignition
systems, which are detailed in the various ignition system drawings.
