Choosing the right ECU for your application

how-to-choose-a-motec-ecuCareful consideration of your applications needs will help determine the right ECU for you. Electron Speed has the ability to customize any ECU with the specifications of your choice.

Club Racer – MoTeC M84
If you are a club racer looking for a flexible programmable ECU to suit your engine management needs, look no further. The M84 offers the best mix of cost effectiveness, simplicity, reliability and the potential for data logging capabilities. This ECU coupled with Electron Speed customer support is a combination capable of suiting any of your needs.

Governing Bodies – MoTeC M1 series
Standardization, tamper resistance, and price are all important factors when looking for a potential spec ECU. The M1 series features configurable password based security to determine which parts of the calibration or logged data are viewable and editable (builder, tuner, customer).

The M1 is relatively early in its design cycle ensuring your series will have the most current ECU. Electron Speed has the ability to build customized code for any foreseeable or unforeseeable needs of the series.

Creative Projects, Engineering Project, Hybrid – M800 or M1 developmental series
If your projects require a high degree of customization, consider the M800 or the M1 development series. Electron Speed would love to help you tackle your complex and interesting projects; hybrids, torque bias, it doesn’t have to be a car!

Pro/Semi Pro Racing – M800 or M1 developmental series
For professional and semi-professional racers or those who require adjustability of all aspects of their engine management hardware. The M800 or M1 developmental series offer flexibility, reliability and Electron Speed customer support.

Are you a DIY’er with an application that isn’t too complex? The M800 has the most flexibility out of the box whereas the M1 requires a customized software package to fully utilize its capabilities.

If you’re a tuner who likes to play with fuel and spark or a tinkerer who would prefer a modern interface, the M1 is the better choice. The M1 has the ability to view current and recently seen values of any variables, pause, go back in time, or even add data. Think of it as an easy to use DVR for your data. The M1 also features searchable and well documented help.
