Modified Vehicles

Vehicles equipped with aftermarket engine components or race-specific modifications may require a custom calibration.

If your Porsche already has Softronic software installed and you’ve added performance upgrades, GTCO can help you obtain the proper calibration to maximize performance while maintaining drivability and reliability.

Important 992 ECU Information

Unlike earlier Porsche models, the 992 GT3 and Speedster DME must be bench unlocked before OBD-II flashing is possible.

Your ECU will need to be removed and sent to Softronic for the initial unlock procedure. Once unlocked, your vehicle can be flashed using the supplied Softronic software and OBD-II interface.

If you have questions about the unlock process, GTCO is happy to guide you through the procedure before purchase.

What’s Included

Every Softronic Performance Software package includes:

• Vehicle-specific ECU calibration
• OBD-II programming cable
• Softronic flashing software
• One VIN software license
• Ability to return the vehicle to the original factory calibration at any time

Note: Initial installation requires the ECU (DME) to be bench unlocked by Softronic before OBD-II programming can be performed.
