MoTeC M84 - Manual (Page 7)

MoTeC Overview 5
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 Narrowband closed loop Lambda control.
The Digital Inputs may be used for wheel speed measurement or to activate
functions such as Dual RPM Limit.
The other inputs may be used for data logging (e.g. Exhaust Gas Temp, Fuel
Pressure etc.) or for special calibration features.
Fuel Injector Outputs
Up to eight injectors may be driven fully sequentially including very low ohm
types (0.5 ohms).
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.
Up to six ignition outputs are available for multicoil applications.
• Up to 8 coils may be driven from one Ignition Output using a MoTeC CDI8 or
MoTeC Ignition Expander.
Auxiliary Outputs
The M84 has eight Auxiliary Outputs that may be used for:
Turbo Waste Gate Control, Idle Speed Control, Gear Change Light, Driver
Warning Alarm (plus many others).
CAN Communications
The CAN Communications system is a high speed network communications
system that allows multiple devices to be connected and communicate with
each other.
The CAN connection is used for all communications with the PC via the ECU
Manager software which includes calibration, diagnostics checking, retrieving
the logged data, firmware upgrading and enabling options.
