 M48 
Please Note: The M48 has been discontinued. Information provided for reference purposes only. Upgrade and Accessory Parts still available. Call us for more information.
The
M48 is our Engine Management System (ECU) with the ability to provide sequential
injection and individual cylinder fuel/ignition trims for up to 8 cylinder
engines and is designed to provide you with the power and quality of our Pro
series but at lower cost by letting you option in only the features you require.
It is designed primarily for performance street cars & bikes but by choosing
the optional features it is perfect for competition use.
Our base system uses 3 Dimensional fuel &
ignition mapping and ignition control to give you the ability to drive your
ignition modules and set your spark timing to be at its absolute best at all
points. Sequential ignition lets you fire the injectors at the optimum time in
the engine cycle. Advanced tuning is an option which gives many extra features
including traction control, the ability to configure the ECU to your existing
sensors, etc. Another option is 512Kb of on board data logging to let you
analyse the engine as it has been running. Configure the system to suit your
needs and enable more options if they are required later.
All M48 models have the accurate control
necessary to meet legislated emissions requirements, including closed loop
narrow band lambda control. The engine must, of course, be emissions
capable.
The M48 can use nearly all the original
equipment and aftermarket ignition triggers, modules and coils, giving it
unmatched flexibility. This avoids the cost and time needed to re-manufacture
the distributor in order to trigger Engine Management Systems (ECU's) which are
not as advanced as the MoTeC system. The M48 can be triggered by either a hall
effect switch, a logic drive or a magnetic sensor, with various signal types and
with intelligent signal filtering insuring proper signal to noise ratio at any
crank speed. Electromagnetic interference can play havoc with electronic
devices, and MoTeC take extensive preventive measures to reject low impedance
conducted interference and to shield from radiated interference.
The heart of the M48 is a Motorola 32 bit
microcontroller with a time co-processor, a choice which puts it at the leading
edge of automotive control systems. Contained in a 132 pin surface mount package
and consisting of over 420,000 transistors the M48 is built to internationally
recognised quality control standards (ISO 9001). That the M48 reads its sensors
2400 times per second, and the entire control program is recalculated 200 times
per second demonstrates its power. In personal computer terms the last PC to use
a 16 bit processor was the '286' released in the early 1980's whereas 32 bit is
still current technology. We were the first and to our knowledge the only people
to have used this processor in this application.
MoTeC's unique software programmable switch
mode drivers can trigger any injector with up to 70% less power usage than other
products, drawing less power from the electrical system and generating less heat
inside the ECU. Comprehensive diagnostics report on injector current usage and
any wiring open/short circuit after each firing of the injector.
There is a comprehensive group of computer
software tools available for the M48, including
- Engine setup, tuning diagnostics and
utilities.
- Monitoring, data logging and analysis.
- Utilities for loading new program code and
enabling special features.
This software has been designed with the
emphasis on useability, enabling you to quickly optimise the setup for your
vehicle.
Other thoughtful M48 features include the use
of programmable flash memory chip to store the control program. This means that
there is no program chip or EPROM to change to upgrade the program. When a new
program feature is offered you simply send the M48 the new code over the
optional MoTeC connector cable and the latest features are available to you.
Flash memory has also been included for the internal data logging, meaning that
the recorded data will never be lost even if power to the ECU is removed. Flash
storage also enables the M48 to retain information without needing internal
batteries which have a finite service life.
