The Syvecs SyvTCM provides standalone transmission control for supported gearbox hardware. Select the gearbox version required for your installation.

Confirm compatibility before ordering: support depends on the complete gearbox and internal TCM identification, not just the donor vehicle or gearbox name. The limitations below apply to the individual versions.

G1 8HP

Part number: SYV-TCM-8HP-G1

Standalone Control for the ZF 8HP45 and 8HP70

The Syvecs SyvTCM provides complete standalone control of supported ZF 8HP45 and 8HP70 Gen1 rear-wheel-drive automatic transmissions.

Designed for engine conversions, restomods, motorsport vehicles and custom installations, the SyvTCM allows the highly capable ZF 8HP transmission to be installed into vehicles that were never originally equipped with it.

The system can operate alongside a Syvecs ECU, aftermarket ECU, OEM engine management system or an older engine installation with minimal electronics.

By combining flexible CAN communication, direct sensor inputs, internal torque modelling and advanced transmission strategies, the SyvTCM provides everything required to achieve fast, smooth and repeatable gear changes across a wide range of vehicle applications.

Supported ZF 8HP Transmissions

The current SyvTCM 8HP control package supports selected:

  • ZF 8HP45 Gen1 RWD transmissions
  • ZF 8HP70 Gen1 RWD transmissions

Only compatible Gen1 rear-wheel-drive mechatronic units with supported Bosch TCU hardware can be used.

The Bosch TCU identification number must be checked before purchasing a transmission, as compatibility cannot be confirmed from the gearbox casing or donor vehicle alone.

Supported TCU identification numbers and example applications can be found in the Syvecs 8HP Quick Start Manual.

Important: Not every Gen1 ZF 8HP mechatronic unit is compatible. Later units using the larger 2048 KB memory configuration are not currently supported.

DQ250

Part number: SYV-TCM-DQ250

Standalone Control for Selected VAG DQ250 MQB Transmissions

The Syvecs SyvTCM provides complete standalone integration of selected Volkswagen Audi Group DQ250 MQB six-speed dual-clutch transmissions.

Designed for engine conversions, motorsport vehicles, restomods and custom installations, the SyvTCM allows the fast-shifting, wet-clutch DQ250 transmission to operate outside its original vehicle platform.

The system communicates directly with the original gearbox controller while reproducing the engine and vehicle information normally provided by the factory ABS, engine ECU, steering-column module and other OEM systems.

The SyvTCM can operate alongside a Syvecs ECU, aftermarket ECU, OEM engine management system or an older engine installation with minimal electronics.

Supported DQ250 Transmissions

The current SyvTCM DQ250 control package supports selected MQB transmissions fitted with the earlier CAN 2.0B-based internal gearbox controller.

These controllers are generally found in VAG vehicles produced between 2015 and 2022. Compatibility must always be confirmed using the complete gearbox and TCM part numbers, as the production year, donor vehicle or gearbox casing alone cannot confirm support.

Example supported DQ250 MQB TCM part numbers include:

  • 02E 927 770 AN
  • 02E 927 770 AQ
  • 02E 927 770 AS

Later DQ250 transmissions fitted to Volkswagen Golf Mk8-platform vehicles use a newer internal controller with CAN FD communication. These CAN FD versions are not currently supported by the SyvTCM.

Important: Not every DQ250 transmission is supported. The SyvTCM control package is designed for selected MQB DQ250 transmissions fitted with the earlier CAN 2.0B-based controller. Golf Mk8 DQ250 controllers using CAN FD are not currently supported. Always confirm compatibility using the complete gearbox and TCM part numbers before purchasing a transmission.

DQ250 — manufacturer key features
  • Standalone integration of selected DQ250 MQB transmissions
  • Supports earlier CAN 2.0B-based DQ250 gearbox controllers
  • Compatible with Syvecs, aftermarket and OEM engine controllers
  • Dedicated emulation of missing OEM vehicle modules
  • Suitable for engine conversions and non-OEM chassis installations
  • Internal torque model for ECUs without torque calculations
  • OEM VAG electronic shifter support
  • Paddle-only control
  • Generic and Grayhill CAN keypad support
  • Automatic and Manual gearbox operation
  • Normal and Dynamic gearbox modes
  • Torque-based clutch and shift management
  • Engine torque-reduction requests
  • Automatic paddle-up control
  • Gear-based RPM shift targets
  • RPM rate-of-change compensation
  • Downshift over-rev protection
  • Launch-control integration
  • Reverse-light output
  • Direct gearbox DTC reading and clearing
  • Gearbox basic settings and clutch relearn support
  • Clutch-pressure monitoring
  • Transmission fault and limp monitoring
  • GPS and IMU integration
  • High-speed internal and USB data logging
  • Live monitoring through Syvecs SCal
  • Flexible Generic CAN Receive and Transmit
  • Physical inputs for non-CAN engine installations

DQ500

Part number: SYV-TCM-DQ500

Standalone Control for Selected VAG DQ500 Transmissions

The Syvecs SyvTCM provides complete standalone integration of selected Volkswagen Audi Group DQ500 seven-speed dual-clutch transmissions.

Designed for high-torque engine conversions, motorsport vehicles, restomods and custom installations, the SyvTCM allows the fast-shifting, wet-clutch DQ500 transmission to operate outside its original vehicle platform.

The system communicates directly with the original gearbox controller while reproducing the engine and vehicle information normally provided by the factory ABS, engine ECU, steering-column module and other OEM systems.

The SyvTCM can operate alongside a Syvecs ECU, aftermarket ECU, OEM engine management system or an older engine installation with minimal electronics.

Supported DQ500 Transmissions

The current SyvTCM DQ500 control package supports selected transmissions fitted with the earlier CAN 2.0B-based internal gearbox controller.

Compatibility must always be confirmed using the complete gearbox and TCM part numbers, as the production year, donor vehicle or gearbox casing alone cannot confirm support.

Example supported DQ500 gearbox applications and part numbers include:

  • Audi RS3 / TTRS MQB – 0DL 300 013 E
  • Volkswagen Tiguan / SEAT Tarraco MQB – 0DL 300 013 AX
  • Volkswagen Tiguan MQB Petrol – 0DL 300 013 H
  • Volkswagen Arteon MQB – 0DL 300 011 QX
  • Volkswagen Transporter T6 – 0BT 300 012 B
  • Volkswagen Transporter T6 Rebuilt Unit – 0BT 300 012 C

From 2023, Audi 8Y DQ500 applications changed to a newer internal gearbox controller using CAN FD communication. These CAN FD versions are not currently supported by the SyvTCM.

Important: Not every DQ500 transmission is supported. The SyvTCM control package is designed for selected DQ500 transmissions fitted with the earlier CAN 2.0B-based controller. Audi 8Y DQ500 controllers using CAN FD, generally fitted from 2023 onwards, are not currently supported. Always confirm compatibility using the complete gearbox and TCM part numbers before purchasing a transmission.
