GAD WT3 Switchable Remapping


Legacy product information

WT3 was an earlier GAD switchable-remapping system described on our original website. This information is intended to help existing owners identify the subject of their enquiry. Current supply, file access and support must be confirmed individually.

Switchable software and the original vehicle


The original WT3 description covered keeping factory software alongside alternative vehicle calibrations and transferring files using a computer. It also described basic fault-code functions. These are historical product descriptions, not a guarantee that a particular unit or vehicle is supported today.

When discussing an older system, the original vehicle and ECU software are important. A device, calibration or backup associated with one vehicle should not be assumed interchangeable with another vehicle simply because the model names match.

What to include in your enquiry


Please provide the unit details, the vehicle it was originally used with, and the reason for your enquiry. If the car has been updated or modified since the files were supplied, include that history too. Avoid writing an unidentified file back to the car while its suitability is uncertain.

If you are researching remapping rather than using an existing WT3, we can discuss the vehicle and your goals directly. Mobile suitability and the programming method will depend on the particular application.
