Hundred Series

Inputs & Outputs O12

MoTeC has a wide range of world class ECUs to cater for almost any application. Our 'hundred series' ECUs include the M400, M600, M800 and M880. A more recent addition to this family is the entry level M84. We also provide Plug-In ECUs for a number of popular vehicles.

M400, M600, M800, M880

These popular ECUs are collectively known as the MoTeC 'hundred series' and are characterised by their ability to control late model vehicles with drive by wire throttle systems and continuously variable camshaft timing, alongside many other advanced functions. They use Windows-based ECU Manager software.

Marine ECUs

These models are fully polyurethane-potted versions of the M400, M600 and M800 ECUs. With an IP67 rated design, they are reliably waterproof and weigh just over 900 grams.

MoTeC Marine ECUs are specifically suited to applications in harsh environments with water, dirt or vibration, for example in PWCs (Personal Water Craft), boats and off road vehicles.

All functions and upgrades are the same as the standard ‘hundred series’ ECUs.

M800 Plug-In ECUs

Available for a wide range of Subaru WRX and Mitsubishi Evo models. They are based on the regular M800, offering the same power and performance, but operating only with saturated drive fuel injectors. M800 Plug-In ECUs eliminate the need to rewire the vehicle because they are fitted with an OEM connector and simply slot into the factory ECU case or plug into the factory harness.

PWC Plug-In ECUs

This range of ECU solutions for PWC (Personal Water Craft) is currently available for Yamaha, Kawasaki, Hydrospace and Sea-Doo.

Complete with a wiring loom and mounting brackets, PWC Plug-Ins are convenient and cost effective to install. They simply plug into the factory wiring harness using the original sensors and fuel system.


The M84 is an entry level ECU based on the M800's advanced technology. It has been specifically designed with a set of features to suit applications with more moderate requirements, while maintaining the tuning accuracy and reliability of the hundred series ECUs. Among many other advanced features, it includes on-board Wideband Lambda and data logging (optional on all other models). The M84 also uses Windows-based ECU Manager software.
