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
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.
