M880 S3

Version 3 ECU Software

The latest software for MoTeC ECUs, Version 3, is developed to optimise tuning for the increasing sophistication of modern engines. It has a range of new and improved features and control functions and an increased table functionality.

V3 software can be sent to any new or existing 'hundred series' ECU—M400, M600, M800 and M880—enabling the latest features even on older systems.

New and Improved Features

  • Ref/Sync Capture
    Crank and cam signals are captured and displayed on a built-in digital oscilloscope. This is invaluable for checking the integrity of the Ref and Sync signals and diagnosing faulty sensors or wiring.
  • Engine Logs
    Three engine histogram logs can be configured to log any channel. For example, one engine histogram might log engine RPM and another oil pressure. Also included is a tell-tale log for storing minimum and maximum values, plus an accumulated values store.

  • Multiple Configurations
    Up to four different configurations can be stored in the ECU and 'switching on the fly' is supported. This can be used in for example rally cars where different maps are used for different weather or road conditions. Also, if switching is integrated in the loom, it can be used to switch the ECU from one car to another.

  • Input Setup
    A completely revised input setup system includes adjustable filtering and diagnostic levels on all input channels.

  • Inputs
    Input data can be accepted from other devices connected via the CAN bus, such as MoTeC Dash Loggers, PLM Lambda meters (up to 12 PLMs can be connected), E888/E816 expanders, or even another MoTeC ECU.

  • Customised sets of channels can be transmitted via RS232 or CAN to another device such as a MoTeC Dash Logger.

  • Improved semi-automatic gearbox function.

New and Improved Control Functions

  • Traction Control
    Major enhancements to the traction control system including power reduction via drive by wire, ignition cut and ignition retard. Includes three 3D tables for aim slip which could be used for driver adjustment, gear compensation, lateral acceleration compensation or for adjustment based on any other channel.

  • Timers
    Full throttle and closed throttle timer channels plus two general purpose timer channels can be used by any table. For example a fuel or ignition compensation table.

  • Idle Speed Control
    All new idle speed control which includes fuel and ignition compensation tables, plus tables for setting the idle RPM. This allows RPM adjustment based on a number of channels.

  • Nitrous Control
    All new Nitrous control system using 3 stages with atack and decay, and a start timer for each stage. The stages can be triggered by throttle, ground speed or digital inputs.

  • Boost Control
    Major enhancements to boost control including PID control with 3D tables.

  • Drive by Wire Throttle Control

    • Can now be used in the overrun boost (anti-lag) system.

    • Supports up to four drive by wire throttle motors using a MoTeC DBW4.

    • Can be used for downshift throttle blip.
  • Lambda Control
    Enhancements to the Lambda control system including new aim Lambda compensation tables which allow the aim Lambda to be varied based on any channel. For example, a driver adjustment channel or the full throttle timer channel.

  • RPM Limit

    • The 3D RPM limit table allows the RPM limit to be varied based on any channel, for example gear or engine temperature.

    • Downshift RPM limiting to match engine RPM to gearbox speed.

Increased Table Functionality

  • 4D Tables
    4D fuel and ignition tables allow engine mapping based on any three channels, for example RPM, throttle and MAP.

  • Input Channels
    Selectable input channels for all tables allows extraordinary flexibility in how tables are used and even allows internal channels such as fuel pulse width or ignition timing to be used as table inputs.

  • Table Axis Sites
    The table axis sites can be varied independently for almost all tables, allowing full optimisation for each table.
  • Accel and Decel Tables
    3D acceleration and deceleration tables for both fuel and ignition.

  • Start Tables
    3D start tables based on cranking time and any other channel such as engine temperature.

Plus numerous other enhancements to functionality and user interface.
