Fabspeed XperTune Performance Software ECU Upgrade. Porsche 996 GT2  ›  FSPOR996GT2ET

The Fabspeed XperTune Performance Software is a custom ECU calibration developed for the Porsche 996 GT2 3.6L, 2001–2005. Designed to optimise the factory engine-management strategy, the software recalibrates key parameters such as fuelling, sensor inputs and boost control to improve horsepower, torque, throttle response and overall drivability.

Fits:

• Porsche 996 GT2 2001-05

Rather than requiring the vehicle's ECU to be removed and sent away for bench flashing, the XperTune system uses a supplied handheld programming device connected through the vehicle's OBD-II port. The original ECU data is read from the vehicle and used by Fabspeed to create a calibration matched to the vehicle's specification and modifications.

Fabspeed publishes output figures of 505 hp and 502 lb-ft compared with its quoted stock figures of 450 hp and 457 lb-ft, representing claimed gains of approximately 55 hp and 45 lb-ft. Actual results can vary according to vehicle condition, fuel quality, modifications and operating conditions.

What This Product Does:

• Reprograms the engine ECU with a performance-oriented calibration.
• Optimises engine-management parameters for increased performance.
• Adjusts fuelling strategies to suit the engine and vehicle specification.
• Optimises boost-pressure control where applicable.
• Improves throttle response and engine drivability.
• Supports increased horsepower and torque.
• Allows the calibration to be tailored to existing vehicle modifications.
• Removes the need to physically remove and ship the ECU for tuning.
• Allows the factory calibration to be restored using the supplied handheld device.
• Provides a reusable programming method for switching between the original and Fabspeed calibration on the same vehicle.

The tune is created using the original ECU file together with information about the vehicle and any installed performance modifications.

When XperTune Should Be Considered:
This software may be appropriate when:

• Additional horsepower and torque are desired.
• The vehicle remains mechanically healthy but improved performance is required.
• Performance exhaust components have been installed.
• Intake or intercooler upgrades have been fitted.
• The ECU needs to be calibrated around existing modifications.
• Improved throttle response is desired.
• The owner wants an OBD-II flashing solution without removing the ECU.
• The ability to return the vehicle to its original calibration is desirable.

The process involves:

• Reading the factory ECU data using the handheld programmer.
• Connecting the handheld device to a Windows PC.
• Supplying the original ECU data and vehicle specification to Fabspeed.
• Fabspeed creating a calibration based on the supplied vehicle information.
• Loading the custom tune onto the handheld programmer.
• Flashing the new calibration into the vehicle ECU through the OBD-II port.

The original calibration remains available so the ECU can later be returned to stock using the handheld device.
