MTC24

The Mectric Transmission Controller (MTC) is a highly flexible device aimed at controlling the most complex transmission and driveline components. Designed with an over abundant amount of processing power to allow for the implementation of extremely complex, no compromise control strategies. The MTC24 has 24 outputs including 16 dedicated proportional current solenoid drivers and 8 high current half bridge drivers.

MTC24 Datasheet

 

Features

Transmission Control

DCT / Multi Clutch / Hydraulic / Air Shift Control. Maximum flexibility.

A primary focus of the MTC is managing Dual Clutch Transmissions in retro-fitted motorsport applications. The highly flexible control functions feature a plethora of dynamically adjustable tables and advanced PID closed loop control systems. This allows predictable, repeatable, and reliable control of line pressures, clutch pressures, clutch touchpoints, take-up and shift pressures.

Torque can be modelled mathematically by the MTC or received over CAN from the engine ECU.

The built in 6 axis accelerometer & gyroscope gives the tuner control over shift automation based on acceleration and inclination for hill start control and decent control.

General Purpose Functions

User logic functions.

User maths expressions.

User configurable 4D table functions for PWM control of solenoids or pumps.

User configurable general purpose PID control functions for target based control of any system.

User configurable timers and counter functions.

 

CAN Bus

The MTC24 hosts two CAN 2.0B transceivers.

Preset protocols make setup of common systems easy and fast. CAN frames can also be fully defined with ID filtering, bit masks, multipliers, divisors and offsets. All runtime variables can be written or transmitted over CAN allowing extreme flexibility.

The extreme flexibility of the CAN system in the MTC allows it to be utilised as a CAN translator system when coupled with less configurable or locked nodes.

 

Reliability

A full host of I/O monitoring, diagnostic functions, and error code generation gives the installer valuable feedback about the integrity and status of the system being controlled, eliminating guesswork during setup and tuning.

The MTC is constructed from AEC-Q100 Automotive Grade components and housed in a billet aluminium chassis, ensuring it's reliability in harsh environments.
