Important: Programming required

The control unit cannot simply be installed and used without programming.

It must be programmed or loaded with the required data according to the vehicle.

Optional cloning service

Upon request, we can handle the transfer of relevant data from your existing transmission control unit.

To do this, you send us your original control unit. We will transfer the required data to the new control unit.

You will then receive the prepared control unit back and can reinstall it in your vehicle.

Optional: Heuschmid Stage 1 Transmission Software

In addition, we offer optimized software for the transmission control unit.

Stage 1 includes, among other things:

• Increase of torque limit to up to 500 Nm
• Adjusted torque limitation in 1st and 2nd gear
• Faster response to shift commands
• Less delay when shifting via paddle shifters
• Optimized shift points in normal mode
• Lower engine speeds in appropriate driving situations

Actual software compatibility depends on the vehicle, engine, transmission, and vehicle configuration.

Control unit + programming from a single source

Correct programming is crucial, especially for electronic transmission control units.

As a Saab specialist, we can therefore not only supply you with the replacement control unit but also offer the necessary data transfer and optimized transmission software upon request.

If you have questions regarding vehicle compatibility or programming, please feel free to contact us before ordering.
