Fits:

• Porsche 911 1987 3.2L G50  

Unlike generic replacement chips that apply universal ignition and fuel maps, this software has been developed from a completely blank programme. Hundreds of hours of coding, road testing and chassis dynamometer development across more than one hundred Carrera 3.2 models have resulted in one of the most thoroughly refined Motronic calibrations available.

The result is a noticeably smoother idle, significantly stronger low and mid-range torque, sharper throttle response, elimination of the characteristic sub-4,000rpm flat spot and measurable horsepower gains throughout the rev range.

1987 24-Pin or 28-Pin DME – Which Chip Do I Need?

1987 was a transitional production year, with Porsche changing from a 24-pin EPROM to a 28-pin EPROM during production.
The only reliable way to determine which version your vehicle requires is to remove the DME control unit and inspect the existing chip
The original EPROM is a black rectangular integrated circuit fitted with a factory foil label displaying a sequence of numbers similar to:1267355xxx

Count the number of legs (pins) on the chip:

• 24 pins – This product is correct.
• 28 pins – You require the 28-pin version.

Please refer to the DME chip installation guide before ordering if you are unsure.

Specifically Developed for 1987 24-Pin Euro Specification Cars

This version has been developed exclusively for:

1987 Porsche 911 Carrera 3.2 Euro/ROW specification 24-pin Bosch Motronic DME Standard rear silencer Sport rear silencer Manual transmission vehicles Standard or mildly modified engines

The default calibration is designed for 95 RON premium unleaded fuel.

For owners using 98 RON premium fuel, an optional dedicated calibration is available to maximise ignition advance and overall engine performance.

Why This Chip Is Different

Rather than modifying the factory programme, this calibration has been completely re-engineered to optimise every aspect of engine operation.

The revised software enhances:

• Ignition timing.
• Fuel delivery.
• Full-load enrichment.
• Part-throttle performance.
• Torque development.
• Throttle response.
• Idle stability.
• Deceleration characteristics.

Every map has been refined through extensive dyno development and real-world road testing to deliver measurable improvements across the entire rev range.

Performance Gains You Can Feel

The improvements extend far beyond peak horsepower.

Typical gains include:

• 6–8% increase in horsepower and torque across the powerband.
• Approximately 12–16 bhp increase on standard engines.
• Around 20 lb-ft increase in torque through much of the rev range.
• 10–20% increase in part-throttle torque and engine efficiency.
• Up to 25–35 bhp improvement around 6,500rpm in certain operating conditions.
• Stronger acceleration from just 1,500rpm.
• Elimination of the familiar hesitation below 4,000rpm.
• More responsive acceleration to the rev limiter.

Cars fitted with polished intake runners, sports silencers or improved induction systems may achieve even greater gains, as the revised calibration allows the engine to make full use of the additional airflow.

Dramatically Improved Drivability

Owners immediately notice improvements in everyday driving, including:

• Smoother idle.
• Virtually eliminated idle hunting.
• Reduced RPM dip during deceleration.
• Reduced overrun popping and backfiring.
• Sharper throttle response.
• Increased low-speed flexibility.
• Stronger mid-range acceleration.
• Improved overtaking performance.
• More progressive engine response.

The revised torque curve gives the impression that the car has become substantially lighter, making it more responsive in every driving situation.

Optimised for Standard or Sport Rear Silencers

Many Carrera owners fit sports rear silencers expecting substantial power gains, but the factory Motronic software continues to use conservative ignition and fuelling strategies.

This calibration has been specifically optimised for:

• Standard factory silencers.
• Performance rear silencers.
• Improved exhaust flow.

By optimising ignition timing and fuel delivery, the engine is able to fully exploit these upgrades while maintaining excellent drivability.

• Reduced RPM dip during deceleration.
• Reduced overrun popping and backfiring.
• Sharper throttle response.
• Stronger low-speed torque.
• Improved overtaking performance.
• More responsive acceleration in every gear.
• Greater flexibility during everyday driving.

The improved torque delivery gives the impression that the vehicle has become significantly lighter, making the Carrera feel far more responsive throughout the rev range.

Optimised for Standard or Sport Rear Silencers

Many Porsche 911 owners install sports rear silencers expecting additional power, but the original Motronic software continues to use conservative ignition and fuelling strategies.

This calibration has been specifically developed to complement:

• Standard Porsche rear silencers.
• Performance rear silencers.
• Improved exhaust flow. 

By optimising ignition timing and fuelling to suit these upgrades, the engine is able to realise significantly greater performance than exhaust modifications alone.

Improved Fuel Efficiency

Performance gains do not necessarily come at the expense of economy.

With optimised ignition timing and more efficient part-throttle calibration, many owners report motorway fuel economy improvements of approximately 10-15%, depending on vehicle condition, fuel quality and driving style.

Performance Upgrade Chip 24-Pin – Euro Spec with SSI or Race/Performance Headers

Unlock the full potential of your 1987 Euro specification Porsche 911 Carrera 3.2 with this OE Match 24-pin Performance Upgrade Chip, specifically developed for cars fitted with SSI heat exchangers or race/performance headers.

 Fits:

• Porsche 911 1987 3.2L G50  

This dedicated calibration is designed for the Bosch Motronic DME used in 1987 Carrera 3.2 models equipped with a 24-pin EPROM. It is not a generic, one-size-fits-all programme. The software has been developed to suit the increased exhaust flow created by SSI systems, tubular manifolds and performance headers, allowing the engine to make better use of these upgrades through revised ignition and fuel mapping.

The result is stronger low and mid-range torque, sharper throttle response, smoother idle quality and more usable power throughout the rev range. The familiar hesitation below 4,000rpm is substantially reduced, with improved response available from as low as 1,500rpm.

For owners who have already upgraded the exhaust system, this chip is one of the most cost-effective ways to ensure those hardware modifications deliver their full performance benefit.

1987 Model Owners – How Do I Know Whether I Have a 24-Pin or 28-Pin Chip?
The 1987 model year was a transitional period during which Porsche changed from a 24-pin EPROM to a 28-pin EPROM.
The vehicle model year alone is therefore not enough to confirm compatibility.
The only reliable way to identify the correct version is to open the DME control unit and inspect the original chip.

The factory EPROM is typically:

• Black and rectangular
• Fitted with a matte foil sticker
• Marked with a number similar to 1267355xxx

Count the chip legs:

• 24 pins: this product is correct
• 28 pins: order the 28-pin version instead

Always confirm the pin count before ordering. Refer to the DME chip installation instructions for guidance on safely accessing and identifying the existing EPROM

Specifically Developed for the 1987 Euro 24-Pin DME

This Performance Upgrade Chip is intended for:

• 1987 Porsche 911 Carrera 3.2 Euro/ROW specification engines
• Bosch Motronic DME with 24-pin EPROM
• SSI heat exchangers
• Race headers
• Performance exhaust manifolds
• Standard or performance rear silencers
• Standard or mildly modified engines

The standard programme is calibrated for 95 RON premium unleaded fuel.

A dedicated 98 RON calibration is also available for customers who consistently use higher-octane fuel and want the ignition and fuel maps optimised accordingly.

What Does the Performance Upgrade Chip Do?

The chip replaces the original EPROM programme within the Bosch Motronic DME and revises the engine management calibration to suit the car’s exhaust configuration.

The software optimises:

• Ignition timing
• Full-load fuelling
• Part-throttle fuelling
• Throttle response
• Low-speed torque delivery
• Mid-range power
• High-rpm performance
• Idle stability
• Deceleration behaviour
• Compatibility with increased exhaust flow

The factory Motronic software was calibrated for the original exhaust system. When SSI heat exchangers or performance headers are installed, the engine can flow more air, but the standard DME programme cannot fully optimise that change.

This dedicated chip helps ensure the engine receives the correct fuelling and ignition strategy to support the freer-flowing exhaust.

Developed from the Ground Up

This calibration was not created by making a few basic changes to the original factory software.

The programme was re-engineered through hundreds of hours of code development, road testing and dynamometer evaluation across a wide range of Carrera 3.2 engines. This extensive testing has identified areas of performance, drivability and efficiency that are not addressed by generic aftermarket chips.

The wide range of available programmes allows the calibration to be matched to:

• Engine market specification
• Exhaust configuration
• Fuel octane
• Intake modifications
• Owner preference
• Overall engine specification

This ensures a more appropriate setup than a universal chip intended to work with every vehicle.

Stronger Low and Mid-Range Torque

One of the most noticeable improvements is the stronger torque delivery at low and medium engine speeds.

The revised calibration helps the engine respond from approximately 1,500rpm, reducing the need to constantly downshift and making the car feel more immediate in everyday driving.

Typical improvements include:

• Stronger acceleration from low rpm
• Increased mid-range pulling power
• Sharper response to small throttle inputs
• Reduced hesitation below 4,000rpm
• Improved overtaking performance
• Greater flexibility in higher gears
• More responsive corner-exit acceleration
• Improved throttle modulation during autocross and fast-road driving

The broader torque curve can make the vehicle feel considerably lighter and more energetic without changing the engine’s fundamental character.

Smoother Idle and Improved Drivability

The revised software also targets common Carrera 3.2 drivability concerns.

It can help reduce:

• Idle hunting
• Sub-idle rpm dipping during deceleration
• Hesitation when returning to idle
• Deceleration backfiring
• Uneven low-speed response
• Flat spots during part-throttle acceleration

This creates a smoother transition between idle, part throttle and full load, improving both urban drivability and performance use.

Expected Performance Gains

Typical claimed gains include:

• Approximately 6–8% increase in horsepower and torque across the powerband
• Around 12–16hp on otherwise standard engines
• Approximately 20 lb-ft of additional torque through areas of the rev range
• Around 10–20% improvement in part-throttle torque, horsepower and efficiency
• Stronger power delivery from 1,500rpm to the rev limit
• Potentially greater gains on engines with SSI systems, polished intake runners and other airflow improvements
• Up to approximately 20hp on suitably modified engines

In certain areas near the top of the rev range, gains may be substantially greater than the peak-to-peak figure because the revised software can reduce the power drop-off found with the standard calibration.

Actual results will vary according to engine condition, exhaust specification, induction setup, fuel quality, ambient conditions and dynamometer method.

Why SSI and Performance Headers Need Matching Software

SSI heat exchangers and race/performance headers improve exhaust gas flow by reducing restriction and improving scavenging.

However, the original DME remains programmed around the factory exhaust system. At full load, the Bosch Motronic system relies heavily on pre-programmed fuel and ignition maps. It cannot automatically make full use of major airflow changes.

A matched performance chip helps by:

• Supporting the increased exhaust flow
• Adding appropriate fuel under load
• Optimising ignition timing
• Improving engine response
• Strengthening high-rpm performance
• Reducing the limitations of the standard map
• Maximising the benefit of SSI or header installation

Without corresponding software changes, the full value of a performance exhaust system may not be realised.

Potential Fuel Economy Improvement

Although this chip is primarily a performance upgrade, the revised part-throttle and ignition mapping may also improve cruising efficiency.

Many customers report highway fuel economy improvements of approximately 10–15%, depending on vehicle condition, driving style, fuel quality and operating conditions.

These figures are customer-reported and should not be considered guaranteed.

Installation Recommendations

Professional installation is recommended.

Before ordering, confirm:

• The vehicle is a 1987 Euro/ROW Porsche 911 Carrera 3.2
• The DME contains a 24-pin EPROM
• The car is fitted with SSI or performance headers
• The preferred fuel programme is 95 RON or 98 RON
