  • Support for Manual or Automatic shift modes, selectable via a driver switch.
  • The Automatic shift mode automatically shifts gears based on a user definable vehicle speed and throttle pedal position. A multi-position switch (up to 10 positions) can also be configured to vary the gear shift points.
  • The Manual shift mode allows the driver to shift up and down at any time via up and down gear shift switches.
  • Configurable gear shift engine speed settings that automatically shift gears when the engine speed is outside the user definable range (e.g. above maximum engine speed).
  • Support for a switching and/or proportional torque convertor lockup clutch solenoid.
  • Fully configurable torque convertor lockup clutch control that can be based on vehicle speed, gear, throttle pedal, transmission temperature, range selector position and torque convertor slip. The proportional solenoid can also be ramped in and out as the torque convertor lockup clutch is applied and released, delivering smoother transitions.
  • Support for a line pressure control solenoid to vary the pressure of the transmission's hydraulic fluid. This line pressure solenoid’s output can be set to be dependent on many variables, including: gear, gear shift state, throttle pedal position, torque convertor lockup clutch state and transmission temperature to give the ideal transmission pressure under all conditions.
  • Support for up to 3 other pressure control solenoids that can be used to vary the line pressure within the transmission (e.g. 3-2 Control Solenoid on a GM 4L60E transmission). These solenoid outputs can be set to be dependent on numerous variables, including: gear, gear shift state, throttle pedal position, torque convertor lockup clutch state, transmission temperature and vehicle speed. Also included are a wide variety of settings that can be used to ramp in and out these solenoids during gear shifts and range selector position changes.
  • Support for up to 4 gear shift solenoids. These shift solenoids can be set to any user defined combination, enabling many transmissions to be run from this single Package.
  • Support for a manual range selector whose position (Park, Neutral, Drive etc.) can be configured from any combination of up to 8 individual switch inputs. This range selector can then be used to limit the gears selectable in each position.
  • Supports input and output shaft speed sensors with calculations for torque convertor, as well as internal clutch and band slip (Gear Slip).
  • Warnings to alert the user of excessive torque convertor and gear slip.
  • Warnings to alert the user of excessive torque convertor and gear slip. Once active, these warnings can reduce engine torque via engine speed limiting or reduced throttle (DBW engines only).
  • Support for a transmission temperature sensor with overrides and trims for the torque convertor lockup clutch, pressure control solenoids and gear shift points.
  • Support for a transmission pressure sensor.
  • Warnings to alert the user of undesired transmission pressures and temperatures.
  • Support for a transmission cooler fan along with an additional temperature and pressure sensor.
  • Support for a transfer case with selector and position switches, allowing the output ratio to be set based on the transfer case selector position.
  • Support for a shift lock solenoid to restrict movement of the range selector under certain conditions.
  • CAN transmit of the most common transmission channels using standard MoTeC CAN templates that can easily import into MoTeC displays and other devices.
  • Configurable engine synchronisation modes to measure engine speed for many common engine types. Refer to the Engine Speed Modes section for current details.
  • Configurable engine synchronisation ignore mode allows for manifold pressure synchronisation.
  • Sensor calibrations available for many common automotive sensors.
  • Support for analogue and digital (frequency or duty cycle) sensors.
  • Support for single wire digital (SENT) sensors.
  • Test settings for most outputs, including injection and ignition outputs, for easier setup.
  • Configurable security for multiple users with differing access options.
  • Configuration of brake state using a switch or pressure sensor.
  • ECU-internal G-force (acceleration) – longitudinal, lateral and vertical.
  • ECU CAN receive from a defined CAN ID for data reception from MoTeC devices. Support for one (M130/M170) or three (M150/M190) CAN buses.
  • ECU CAN transmit of the most common channels using standard MoTeC CAN templates that easily import into MoTeC displays and other devices.
  • 8 configurable switches and 8 rotary switches (wired or CAN input), each with up to 10 positions.
  • Throttle Pedal.
  • Vehicle speed measurement using wheel speed sensors, estimation or GPS.
  • Configurable warning system with light and CAN output.
