The M84 is a versatile, race-bred ECU that is suitable for a broad range of high performance applications, including engines with up to 8 cylinders. It also suits rotary engines with twin, triple or quad rotors.
This new, entry level ECU is based on the advanced technology in MoTeC's benchmark M800, with a package of features to suit more moderate system requirements. It includes on-board Wideband Lambda plus 512 kB of data logging memory as standard.
Install it as a stand-alone ECU or as part of a complete motorsport-ready engine management and data acquisition solution.

Several options are available as upgrades to customise and grow your system. These additional features are activated through a simple password system, at any time when you need it.
For the M84 engine management system the following upgrades are available:
Dual Wideband Lambda
Single on-board Wideband Lambda is included as standard, with a dual option available as an upgrade for applications that require more than one Lambda input.
Advanced Functions
•Traction Control and Launch Control (2, 3 or 4 wheel)
•Hi/Lo Injection (secondary injection)
•Gear Change Ignition Cut (flat shifts)
•Overrun Boost Enhancement (anti-lag)
Traction Control ‡
The Traction Control option enables user-programmable Traction and Launch Control. Traction Control reduces engine power, by cutting cylinders, to limit wheel spin when traction is broken.
Hi/Lo Injection ‡
Hi/Lo injection enables control of primary and secondary sets of injectors. The injectors are controlled using a 3D table to define the balance of fuel flow between primary and secondary injectors.
Gear Change Ignition Cut ‡
Gear Change Ignition Cut (also known as 'flat shift') momentarily cuts engine power to allow a gear up-shift at wide open throttle. An input to the ECU is used to trigger the cut.
Overrun Boost Enhancement ‡
Enables boost control to reduce turbo lag and improve throttle response in tight and twisty stages for turbocharged cars, specifically in rally events.
‡ Traction Control, Hi/Lo Injection, Gear Change Ignition Cut and Overrun Boost Enhancement are available separately or as part of Advanced Functions.

To complete your installation, MoTeC has a large range of products available, all designed and/or tested to ensure they work well with your ECU.
Communication Cables
To configure the M84, a communication cable is required to connect to a PC. On most computers a UTC (USB to CAN) adaptor should be used to connect to the USB port.
Wiring Looms
Generic wiring looms to be terminated to suit your installation are available.
Fuel Delivery
Components to deliver the right amount of fuel to the engine including fuel injectors, pumps, regulators, filters, fittings and adapters.
Ignition Systems
Inductive and capacitive ignition devices, including the eight channel CDI8, ignition expanders, ignition coils and distributors.
Sensors
Lambda sensors, temperature sensors, pressure sensors, crank, cam and speed sensors, force and motion sensors, and position sensors.
Shift Lights
SLM Shift Light Module and single shift lights.
Displays
To display information to the driver, connect the ECU to any MoTeC dash.

MoTeC’s professional, race-grade electronics are sophisticated and therefore it is highly recommended that installation is performed by a professional installer. It is NOT advised for the average installer. An advanced understanding of electrical systems is necessary. Fischer Motorsports will support all sales and also offers professional grade wiring harnesses and installation services for all applications. We have 10+ years of professional race experience based upon MoTeC control and specialize in Power train, Chassis, Drivetrain, and Data programming both at our facilities, onsite customer dyno/track support, or even remote support. Please remember that if you cannot find the time or finances to do the job right the first time, you will ultimately end up looking for time or funds to do it over again. Select us or find a qualified installer, it will ultimately increase your results and minimize future expenses or downtime related to improper setup or installation.
