MoTeC's unique M1 technology redefines the meaning of customisation, delivering total control without compromise, while highly advanced security strategies make these ECUs ideal for both category managed and unrestricted applications.

The M181 is a Diesel/Direct Injection ECU that offers full control for most modern, high pressure, piezo injectors, without the need for additional amplifier boxes.

LICENCING :

At the time of purchase, an M1 ECU needs to be Licensed for use with a particular Package or a Development Licence.

Packages

An M1 Package is the file that is loaded into an M1 ECU. An M1 Package contains the entire ECU state including the tuning data, worksheets, security and the M1 firmware. M1 Packages themselves are opened and modified in M1 Tune.

  • GP Packages

    MoTeC offers a suite of General Purpose Packages that allow an M1 ECU to be tuned to any number of applications. The flexibility of these GP Packages enables a tuner to configure the same ECU to very different engine setups, including those with road vehicle systems to maintain, such as air conditioning.

    GP Packages are available in variants such as Advanced, Race, Paddle shift and Direct Injection.

  • Targeted Packages

    • Public Packages

      These are Packages specifically developed in-house by MoTeC engineers for a particular engine or vehicle. In some cases this includes integration with vehicle control systems beyond the engine, for example, stability control and cruise control.

      For some targeted applications, the M1 ECU is available in a complete Plug-In Kit which includes any additional hardware that may be required.

    • Partner Packages

      These are Packages developed by a MoTeC Partner Developer. It may be based on a Public Package with unique features added by the developer to offer a specific solution.

      MoTeC support staff will not provide assistance for these Packages, it will be provided by the Partner.

    • Category Packages

      These are Packages developed in-house by MoTeC engineers written specifically for the category, limiting the functionality to the class requirements.

Development Licence

When an M1 ECU is teamed with a Development Licence, it allows users to develop unique control strategies, or make modifications to existing M1 Packages. Using M1 Build software, experienced code writers can tailor the functionality of a single ECU or create a Partner Package for ongoing sales.

UPGRADING :

Logging Upgrades

There are three Logging Licence levels. The level determines the number of channels and sample rates available. Logging Level 1 Licence is diagnostic logging, which comes standard with the product, and includes a fixed log set and sample rates.

  • Logging Level 2 Licence: includes 2 log sets, up to 200 channels (including Level 1 diagnostics logging) and a maximum 200 Hz sample rate.

  • Logging Level 3 Licence: includes 8 log sets, up to 2000 channels (including Level 1 diagnostics logging) and a maximum 1000 Hz sample rate.

Pro Analysis

The Pro Analysis upgrade is the professional version of MoTeC's i2 data analysis software and provides advanced mathematics, multiple overlay laps, and unlimited components, workbooks and worksheets.
