M141

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 PackagesThese 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 PackagesThese 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 PackagesThese 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.

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.

Communication (UI)

User communication with the ECU requires an Ethernet connection. A cable providing an Ethernet plug and suitable pin termination for the M1 mating connector can be purchased from MoTeC Dealers.

Inputs

Voltage range: -30 V to 35 V

Outputs

Maximum current on outputs:

• Low Side Injector outputs: max 3.5 A, RMS 2 A
• Half Bridge outputs: Low Side 12 A, High Side 9 A, RMS 4 A

Wire Gauges

• Battery
  • Bat_Pos: all pins should be connected with AWG20, AWG18, or AWG16 wire to a switched battery supply
  • Bat_Neg: all pins should be connected with AWG20, AWG18, or AWG16 wire to a chassis ground or battery negative terminal. ‘Star’ distribution should be employed to ensure that no ECU ground currents are mixed with actuator ground currents
  • Recommended minimum supply wiring: 3x Bat_Pos, 4x Bat_Neg
  • Max supply voltage 35 V
• OutputsDepending on the current draw for some outputs, a minimum wire gauge is recommended for safe operation:
  • Low Side Ignition, Peak Hold Injector, Low Side Injector outputs: AWG20 (ideally) and AWG22 (optional)
  • Half Bridge and Full Bridge outputs: these outputs may be used to drive low side actuators, throttle servos, and direct injection pumps. Wire size should be chosen to suit the current requirements of the actuator device. For example, throttle servos and direct injection pumps should use AWG18 or AWG20 wiring
  • Half Bridge or Peak Hold Injector outputs provide internal recirculation circuitry, whereas all Low Side outputs do not. In applications where camshaft solenoids and other inductive devices cannot be driven from outputs with internal recirculation circuitry, external recirculation by means of a diode can be installed to prevent slow turn-off of some devices
