OE Match 28-Pin Performance Upgrade Chip – USA/Canada Specification 

Unlock the full performance potential of your 1987-1989 USA/Canada specification Porsche 911 Carrera 3.2 with the OE Match 28-Pin Performance Upgrade Chip. Developed specifically for 930/21 and 930/25 catalyst-equipped engines in standard configuration with the factory catalytic converter and either the original or a sports rear silencer, this precision-engineered ECU upgrade delivers noticeably sharper performance while maintaining factory reliability.
                     
Fits:

• Porsche 911 1987-1989 3.2L G50           

Unlike generic replacement chips, the OE Match Performance Chip has been developed from a completely new calibration. Hundreds of hours of coding, road evaluation and dyno testing on over one hundred Carrera 3.2 models have produced a refined ignition and fuel map that unlocks performance hidden within the Bosch Motronic system.

Transform the Way Your Carrera Drives
The improvements extend far beyond peak horsepower. Proprietary software algorithms—exclusive to OE Match—have been developed to improve every aspect of the driving experience by delivering:

• Smoother, more stable idle
• Virtually eliminating idle hunting
• Reduced RPM dipping on deceleration
• Reduced overrun backfiring
• Stronger low and mid-range torque
• Sharper throttle response
• Elimination of the factory flat spot below 4,000 rpm
• Increased pulling power from as little as 1,500 rpm

The result is a Carrera that feels significantly more responsive and eager throughout the rev range, with many owners describing the transformation as feeling like the car has shed 500-600 pounds in weight.

Many customers also report 10-15% improvements in highway fuel economy, thanks to improved part-throttle efficiency.

Engineered for Standard USA & Canada Specification Cars

This chip has been specifically calibrated for:

• 1987-1989 Porsche 911 Carrera 3.2 USA & Canada specification
• Engine codes 930/21 and 930/25
  
• Standard engine configuration
• Factory catalytic converter
• Standard or sports rear silencer
• Bosch Motronic DME with 28-pin EPROM

Every calibration has been developed to maximise performance while maintaining smooth drivability, reliability and safe engine operation.

Is Your 1987 Carrera a 24-Pin or 28-Pin Car?

1987 was a transitional production year, with Porsche changing from a 24-pin DME EPROM to a newer 28-pin version during production.

If you own a 1987 Carrera, the only reliable way to identify which chip your car requires is to remove the DME control unit and count the number of pins on the original EPROM. The factory chip is a black rectangular unit fitted with a silver foil label displaying a part number similar to 1267355xxx.

If your DME contains a 28-pin EPROM, this is the correct upgrade chip. If it has a 24-pin chip, you'll require the dedicated OE Match 24-pin version instead.

Why Choose OE Match?

This is not a "one-size-fits-all" performance chip. Every OE Match calibration has been developed through extensive coding, dyno testing and real-world driving to optimise ignition timing and fuel delivery for individual Porsche engine configurations.

The result is stronger acceleration, improved drivability, enhanced throttle response and measurable performance gains—all while retaining the refinement and reliability expected from an air-cooled Porsche.
