Fabspeed XperTune Performance Software ECU Upgrade. Porsche 997.2 GT2 RS  ›  FSPOR9972GT2RSET

The Fabspeed Porsche 997.2 GT2 RS XperTune Performance Software is a specialist ECU tuning upgrade developed for the 2011 Porsche 911 GT2 RS (997.2), equipped with the 3.6-litre twin-turbocharged flat-six engine.

Fits:

• Porsche 997 MKII GT2 RS 2011-13

Developed by Fabspeed Motorsport, XperTune is designed to enhance horsepower, torque, throttle response and overall engine performance by optimising selected parameters within the vehicle's factory Engine Control Unit (ECU).

The Porsche 997.2 GT2 RS is one of the most performance-focused versions of the 997-generation 911, combining lightweight construction, rear-wheel drive and a powerful twin-turbocharged engine.

Fabspeed's XperTune Performance Software builds upon these characteristics by providing a revised engine management calibration designed to improve power delivery without requiring replacement of the original ECU.

The system includes a handheld OBD-II tuning device, allowing the original ECU information to be read and a vehicle-specific performance calibration to be installed through the diagnostic port.

Unlike traditional ECU tuning procedures that may require the control unit to be removed and sent to a specialist, the Fabspeed handheld system enables the programming process to be completed without removing the ECU.

The software modifies applicable engine management parameters, including fuelling, sensor-related calibration and turbocharger boost-control settings, where supported by the vehicle's ECU.

The aim is to improve acceleration and engine responsiveness while retaining practical drivability.

Fabspeed advertises performance gains of +64 horsepower and +89 lb-ft of torque on its product page.

However, the detailed power table appears to repeat figures associated with the earlier 997 GT2 rather than the 997.2 GT2 RS. The advertised gains should therefore be treated as unverified for this specific application until Fabspeed confirms the relevant GT2 RS test results.

Each calibration is prepared using data read from the vehicle's original ECU, along with information supplied about its specification and any existing performance modifications.

The handheld device also stores the factory calibration, allowing the vehicle to be returned to its original software configuration when required.

Ideal for Porsche GT2 RS owners seeking greater performance from an otherwise healthy engine, the Fabspeed XperTune system provides a specialist, reversible software upgrade without requiring extensive mechanical modifications.

What This Product Does:
The Fabspeed XperTune Performance Software modifies selected operating parameters stored within the Porsche 997.2 GT2 RS engine control unit.

The ECU uses information from engine sensors to manage combustion, fuel delivery and turbocharger operation.

By revising the relevant calibration settings, Fabspeed aims to improve the engine's performance characteristics.

• Engine Performance Optimisation: Revises selected ECU calibration parameters to increase performance potential.
• Increased Horsepower Potential: Designed to deliver greater engine power compared with the original calibration.
• Improved Torque Delivery: Intended to enhance torque output and acceleration.
• Sharper Throttle Response: Helps provide a more responsive reaction to accelerator input.
• Turbocharger Boost Optimisation: Adjusts applicable boost-control parameters to support the intended power delivery.
• Fuel Calibration: Refines relevant fuel-management settings for the specified tuning configuration.
• Enhanced Acceleration: Increased engine output can support stronger acceleration under suitable conditions.
• Vehicle-Specific Calibration: Uses the vehicle's original ECU information and details of its existing modifications.
• OBD-II Programming: Allows ECU data to be read and the performance tune installed through the diagnostic port.
• No ECU Removal Required: Eliminates the need to remove the ECU for the standard handheld programming process.
• Factory Software Backup: Saves the original ECU calibration.
• Return-to-Stock Function: Allows the original factory software to be restored using the handheld device.
• Support for Compatible Modifications: Enables Fabspeed to consider relevant intake, exhaust and other modifications when preparing the tune.
• Convenient Programming Process: Uses a handheld device and compatible Windows computer.
• Improved Driving Experience: Designed to enhance the GT2 RS's already substantial turbocharged performance.

• The Porsche 997.2 GT2 RS was designed as a lightweight, highly focused performance version of the 911.
• Its 3.6-litre twin-turbocharged engine delivers substantial power through the rear wheels, creating a distinctive and demanding driving experience.
• ECU tuning offers a way to modify the characteristics of the engine without replacing the original control unit or carrying out extensive mechanical upgrades.
