Fabspeed DME Chip Upgrade.

The Fabspeed Porsche 964 Carrera DME Chip Upgrade is a performance engine management upgrade designed to enhance horsepower, torque, throttle response and overall driving characteristics of the Porsche 911 Carrera 964.

Fits:

  • Porsche 964 (911) C2 1989-94
  • Porsche 964 (911) C4 1989-94
Developed specifically for the naturally aspirated 3.6-litre air-cooled flat-six engine, this performance chip optimises the factory Digital Motor Electronics (DME) engine management calibration to improve engine performance and power delivery.

Unlike generic performance chips, the Fabspeed DME upgrade is available with different programming configurations to accommodate various engine modifications, fuel octane requirements and driving preferences.

Through extensive development, road testing and dynamometer evaluation, Fabspeed has created performance calibrations designed to extract additional power while improving engine responsiveness throughout the rev range.

In Fabspeed's published testing, a modified Porsche 964 RS America produced an increase of 14 wheel horsepower, alongside torque improvements of approximately 8–17 lb-ft across parts of the engine's operating range.

Suitable for Porsche 964 Carrera 2 and Carrera 4 models manufactured between 1989 and 1994, this upgrade is ideal for enthusiasts seeking improved engine performance without extensive mechanical modifications.

What This Product Does:
The Fabspeed DME Chip Upgrade modifies the engine management calibration within the factory DME control unit, adjusting selected operating parameters to improve power delivery and engine response.

Its key functions include:

  • Increased Horsepower: Optimises engine management settings to help extract additional power from the naturally aspirated 3.6-litre engine.
  • Improved Torque Delivery: Enhances torque characteristics across portions of the engine speed range, supporting stronger acceleration.
  • Enhanced Throttle Response: Helps the engine respond more promptly to accelerator input.
  • Optimised Fuel Delivery: Adjusts fuel management calibration to support the intended air/fuel mixture under appropriate operating conditions.
  • Ignition Timing Optimisation: Refines ignition mapping to improve combustion performance when used with the specified fuel grade.
  • Improved Power Delivery: Aims to provide smoother, more responsive engine performance throughout the usable rev range.
  • Performance Modification Compatibility: Available with calibrations suited to selected exhaust, intake and other engine modifications.
  • Fuel Octane Compatibility: Offers different programming options according to fuel grade and market specification.
  • Factory DME Integration: Upgrades the existing engine management system rather than requiring a complete standalone ECU conversion.
  • Custom Tuning Options: Special programming may be available for modified engines, alternative rev limits or specialised performance applications.

Why Upgrading Matters:
  • Upgrading the factory engine management calibration with the Fabspeed Porsche 964 Carrera DME Chip provides an opportunity to improve the performance and responsiveness of the classic air-cooled Porsche 911.
  • The original DME calibration was developed to accommodate factory performance requirements, fuel quality, emissions standards and everyday driving conditions.
  • A performance-oriented calibration can adjust selected fuel and ignition parameters to improve power delivery while taking advantage of the engine's existing capabilities.
  • For drivers seeking a more responsive and engaging driving experience, the Fabspeed upgrade can provide noticeable improvements in acceleration and throttle response without requiring major internal engine modifications.
  • The upgrade can be particularly beneficial when combined with compatible performance exhaust and intake modifications, where changes to airflow may benefit from an appropriately matched engine management calibration.
  • Selecting the correct programme is essential. Fuel octane requirements, vehicle market specification and existing engine modifications must be considered to ensure the calibration is suitable for the individual vehicle.
  • Unlike replacing the entire ECU, a compatible DME chip upgrade retains the original engine management architecture, making it an appealing option for owners wishing to preserve much of the original vehicle configuration.
  • For Porsche 964 owners undertaking performance upgrades, engine optimisation or sympathetic restoration projects, the Fabspeed DME Chip Upgrade offers a specialist tuning solution designed to enhance the driving characteristics of the iconic 3.6-litre flat-six engine.
