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.  Install it as a stand-alone ECU or as part of a complete motorsport-ready engine management and data acquisition solution. 

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.  The new Marine versions will be specifically suited to applications in harsh environments with water, dirt or vibration, for example in PWC (Personal Water Craft), boats and off road vehicles.


A powerful and cost-effective ECU for modern 4-cylinder and 2-rotor applications.


Ideal for late model 6-cylinder engines and twin or triple-rotary engines.


Suitable for virtually any application - modern engines with up to 12 cylinders as well as engines with twin, triple, or quad rotors.

M800 Plug-In

MoTeC M800 Plug-In ECUs are fully programmable, direct replacements for factory ECUs on a select number of popular vehicle models.


MoTec's top of the line! For professionals driving modern engines with up to 12 cylinders or twin, triple or quad rotor applications.


Lightweight and compact, the M2R is dedicated to run 2-rotor engines and is a derivative of the M4 system.


The M4 represents excellent value for sequentially injected 4-cylinder and 2-rotor applications.


Used in Australia's V8 Supercar series, the M48 represents excellent value for applications of up to 8 cylinders and 2-rotor use.
