Performance Upgrade Chip – Non-Varioram with Lightweight Flywheel & Clutch
Unlock the full potential of your 1994-1995 Porsche 993 Non-Varioram with the OE Match Performance Upgrade Chip, developed specifically for cars fitted with an RS lightweight flywheel and clutch. Designed for manual and Tiptronic (non-Driveblock) models, this advanced Bosch Motronic calibration delivers stronger low and mid-range torque, sharper throttle response and improved drivability while incorporating the latest Lightweight Flywheel (LWF) software solution.
Fits:
- Porsche 993 (911) C2 1994-95
- Porsche 993 (911) C4 1994-95
Compatible with Bosch Motronic DME 0.261.203.675 and the
following Porsche DME part numbers:
- 99361812403
- 99361812404
- 99361812405
- 99361812406
Designed for Lightweight Flywheel Conversions
Fitting an RS lightweight flywheel allows the engine to rev more freely and respond faster, but many conversions suffer from unstable idle, RPM dip and stalling during deceleration or when pulling away.
OE Match has developed one of the most advanced software solutions available to eliminate these issues while enhancing the performance benefits of the lightweight flywheel.
The latest calibration:
- Eliminates lightweight flywheel stalling
- Prevents RPM dropping below idle during deceleration and gear changes
- Improves clutch engagement from standstill
- Reduces unnecessary clutch slip and wear
- Maximises the faster throttle response of the lightweight flywheel
Former OE Match customers can also have earlier chips updated to the latest LWF coding.
Unlock the Hidden Performance of the 3.6-Litre Flat-Six
The factory Bosch Motronic calibration leaves considerable performance untapped. OE Match software has been extensively developed to remove the familiar flat spot below 4,000 rpm, giving the engine stronger pulling power from low RPM and significantly improving throttle response.
Benefits include:
- Increased low and mid-range torque
- Sharper throttle response
- Eliminates the factory sub-4,000 rpm hesitation
- Improved acceleration throughout the rev range
- Dyno-proven horsepower gains
- Smoother, more responsive power delivery
The result is a 993 that feels noticeably more eager, making full use of the lightweight flywheel's quicker engine response.
Premium Fuel Calibration
Every OE Match chip is calibrated for 91 AKI (95 RON) premium unleaded fuel as standard. If you regularly use 93 AKI (98 RON) fuel, a dedicated 98 RON calibration can be supplied. Simply select your preferred fuel grade when ordering.
Optional Immobiliser / Driveblock Delete
For vehicles originally equipped with Porsche's Driveblock immobiliser, this chip can also be supplied with the immobiliser function disabled.
This removes the need to deactivate the immobiliser with the key fob before every journey, returning the vehicle to the operation of a factory non-Driveblock model.
To complete the conversion, install jumper relay 96461018400 into relay position R61, exactly as Porsche specified on non-Driveblock vehicles.
Ordering Information
Porsche fitted six different Bosch Motronic DMEs to 1994-1995 Non-Varioram models.
Before ordering, remove the DME unit from beneath the left-hand front seat and verify the Bosch or Porsche part number shown on the Motronic label to ensure the correct chip is supplied.
Why Choose OE Match?
Unlike generic replacement chips, every OE Match calibration is developed through extensive dyno testing and real-world road evaluation to suit the exact vehicle specification.
