ENGINE MANAGEMENT

The main function of a programmable Engine Management System / Engine Control Unit (ECU) is to provide full control of the engine over all possible ranges of operating conditions. At any given point (load/rpm site) the user is able to precisely set the amount of fuel injected and the optimum ignition timing.

The number of sites over which the engine is tuned can also be chosen, allowing extra sites for fine-tuning in certain areas (if required).

It does this by taking measurements from a number of sensors, then uses the calibration data to make compensations to the basic engine map based on current operating conditions.

M800 ENGINE MANAGEMENT SYSTEM

The M800 offers the next generation in Engine Management Systems. This system has been developed through rigorous research and practical field-testing. The M800 retains all the best features of our previous ECU's, while offering a combination of unsurpassed power and flexibility.

better.

A digital triggering system that is customisable and programmable to suit any engine and includes sophisticated diagnostics that monitor the quality of trigger signals.
The M800 talks to most existing sensors within your vehicle, saving costly additions of new sensors.

DIGITAL TRIGGERING SYSTEM

Flexibility - Programmable Trigger Levels: The DTS gives greater flexibility allowing the exact trigger levels to be set to suit the trigger sensor system. This ensures maximum compatibility with the trigger sensors.

Improved Noise Rejection - Programmable Filter Characteristics: Programmable filter characteristics allow the noise filter characteristics to be adjusted to suit the sensor system which gives improved noise rejection. This ensures the integrity of the trigger signals even in the most noisy environments.

Advanced Diagnostics: The DTS continuously monitors the quality of the trigger sensor signals and will give a warning if the quality of the signal is poor allowing trigger system problems to be rectified before they cause an operational problem.

Accuracy: Precision timing accuracy due to true zero crossing detection for magnetic trigger sensors.

M800 Software

The M800 software has been designed with an emphasis on useability, which enables you to quickly optimise the setup of your vehicle. It is both user friendly for the beginner and a powerful tool for experts. All software is menu driven and has extensive help screens.

The key software is:

ECU Tuning Software

The ECU Manager software is designed for setup, tuning and diagnostics of the M800. Tuning may be done on-line (with the ECU connected) of offline. The ECU Manager software allows viewing of all sensor readings, output settings, status reading, compensations and diagnostic errors.

Other features include: Quick Lambda (automated fuel adjustment), 3D graphing of calibration tables, site target, output testing, files comparison, user definable table inter-polation, table export, table mathematics and on-line help.

Interpret - Analysis

The Interpret software provides advanced tools to assist in analysing the logged data quickly and efficiently. Data can be collected from M800's internal log memory, by telemetry, or by direct connection to a PC. The information contained within the log files can be viewed numerically or graphically.

M800 UPGRADES

The M800 has various options which are field upgradeable using a password and enabling system. Upgrade options include:

Logging
Gives you access to continuous recording of the operating parameters of the engine and vehicle including diagnostic features and Track Mapping.

Pro Logging
Enables advanced data analysis with Graph Overlays, XY Plots, Maths Functions, Virtual Instrument Display and Rainbow Track Maps.

Wideband Lambda (air fuel ratio)
Allows the use of NTK, UEGO or Bosch LSU high accuracy Wideband Lambda sensors.

Telemetry
Enables the transmission of data from the M800, whilst in operation, to another point (e.g. the pits) in real time.

DIAGNOSTICS MONITORING SYSTEM

The diagnostics monitoring system monitors all aspects of the ECU operation, including:

Advanced diagnostics on the Digital Trigger System.
Open Circuit and Short circuit detection on the Injector.
Sensor fault detection on the sensor inputs.

This system helps to identify many of the wiring and sensor faults that may occur during operation allowing problems to be fixed quickly, particularly when combined with the ECU's powerful data logging system.

INDIVIDUAL CURRENT SETTING OF INJECTORS:

The current drive characteristics of each injector output is individually programmable. This allows different types of injectors to be used in Hi/Lo injector applications.
