The familiar delay below 4,000rpm is substantially reduced, allowing the engine to respond from as low as approximately 1,500rpm and pull more strongly towards the rev limit.

For owners who have already invested in SSI heat exchangers or performance headers, this chip helps ensure the hardware upgrade is supported by appropriate ignition and fuel mapping.

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 which chip is fitted.
The only reliable way to identify the correct version is to open the DME control unit and inspect the existing EPROM.

The original chip is typically:

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

Count the chip legs:

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

Always confirm the pin count before ordering. Refer to the chip installation instructions for guidance on opening the DME, identifying the EPROM and safely installing the replacement chip.

Specifically Developed for 1987-1989 Euro 28-Pin DME Cars

This Performance Upgrade Chip is intended for:

• Porsche 911 Carrera 3.2 models from 1987 to 1989 Euro and Rest of World specification engines
• Bosch Motronic DME systems with a 28-pin EPROM
• SSI heat exchangers
• Race headers
• Performance exhaust manifolds
• Tubular exhaust headers
• Standard or performance rear silencers
• Standard or mildly modified engines

The default Euro/ROW calibration is programmed for 95 RON premium unleaded fuel.

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

What Does the Performance Upgrade Chip Do?

The chip replaces the original EPROM programme inside the Bosch Motronic DME and changes the engine-management calibration to better suit the improved airflow created by SSI or performance manifolds.

The revised software optimises:

• Ignition timing
• Full-throttle fuelling
• Part-throttle fuelling
• Low-rpm torque delivery
• Mid-range acceleration
• High-rpm power
• Throttle response
• Idle control
• Deceleration behaviour
• Exhaust-system compatibility

The original Porsche programme was developed around the factory exhaust system and conservative worldwide operating requirements. Once SSI heat exchangers or freer-flowing headers are fitted, the engine can move more air, but the standard software cannot fully optimise that increased flow.

This dedicated calibration helps provide the fuel and ignition strategy required to make better use of the exhaust upgrade.

Developed from the Ground Up

This is not simply a factory programme with a small number of values altered.

The software was developed through hundreds of hours of coding revisions, road testing and dynamometer evaluation on more than one hundred Porsche Carrera 3.2 models. This extensive development process identified areas of performance, responsiveness and efficiency that can remain restricted by the original calibration.

A wide range of programmes allows the chip to be matched to:

• Euro/ROW engine specification
• SSI or performance header configuration
• Rear silencer type
• Fuel octane
• Intake modifications
• Additional engine upgrades
• Owner preferences

This tailored approach helps deliver more appropriate fuelling and ignition control than a universal aftermarket chip.

Stronger Low and Mid-Range Torque

One of the most noticeable improvements is the increase in usable torque at low and medium engine speeds.

Power delivery begins from approximately 1,500rpm, reducing the delay commonly experienced below 4,000rpm. This makes the Carrera more responsive during normal road use while also improving corner-exit acceleration during fast-road, track and autocross driving.

Typical improvements include:

• Stronger acceleration from low rpm
• Greater mid-range pulling power
• Faster response to throttle inputs
• Reduced hesitation below 4,000rpm
• Improved overtaking performance
• Greater flexibility in higher gears
• Stronger acceleration out of corners
• More precise low-rpm throttle control

The broader torque delivery can make the car feel significantly lighter and more immediate without changing the essential character of the air-cooled flat-six.

Smoother Idle and Improved Drivability

The proprietary calibration also targets several common Carrera 3.2 drivability characteristics.

It can help reduce:

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

The result is a smoother transition between idle, part throttle and full load, making the engine more refined during everyday use and more predictable during performance driving.

Expected Performance Gains

Typical claimed improvements include:

• Approximately 6-8% increase in horsepower and torque throughout 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 engine efficiency
• Stronger power delivery from approximately 1,500rpm to the rev limit
• Potentially greater gains on engines with SSI systems, performance headers, polished intake runners and other airflow upgrades
• Up to approximately 20hp on suitably modified engines

In some areas near the upper end of the rev range, particularly around 6,500rpm, gains may be considerably higher than the peak-to-peak figure because the revised calibration can reduce the power drop-off associated with the factory programme.

Actual results will vary according to engine condition, exhaust design, rear silencer, intake specification, 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 Motronic DME remains calibrated for the factory exhaust system.

At full throttle, the DME operates primarily from pre-programmed ignition and fuel maps. It cannot automatically make full use of significant exhaust and induction modifications.

A matched performance chip helps by:

• Supporting increased exhaust flow
• Providing appropriate full-load fuelling
• Optimising ignition timing
• Improving throttle response
• Strengthening high-rpm power
• Increasing low and mid-range torque
• Reducing the restrictions of the factory calibration
• Maximising the benefit of SSI or performance header installation

Without corresponding software changes, the full performance value of upgraded manifolds may not be realised.

Potential Fuel Economy Improvement

Although this chip is primarily intended to improve performance, the revised part-throttle and ignition calibration may also increase cruising efficiency.

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

These figures are customer-reported and are not guaranteed, as fuel consumption will vary between vehicles and drivers.

Installation and Ordering Recommendations

Professional installation is recommended.

Before ordering, confirm:

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

A healthy engine and correctly functioning ignition and fuel systems are essential for achieving the intended results safely.y.

OE Match Performance Upgrade Chip ROW/Euro Spec with SSI or Race/Performance Headers

Unlock the full benefit of your upgraded exhaust system with this OE Match Performance Upgrade Chip, developed specifically for ROW and European specification Porsche 911 Carrera 3.2 models fitted with SSI heat exchangers or race/performance headers.

 Fits:

• Porsche 911 1984-1986 3.2L  

The factory Bosch Motronic DME calibration was designed around the airflow characteristics of the original exhaust system. When SSI heat exchangers, tubular manifolds or high-flow performance headers are installed, the engine can move more air, but the original software cannot fully optimise the revised exhaust flow. This purpose-developed chip recalibrates ignition timing, fuel delivery and throttle response to help the 3.2-litre flat-six make proper use of those modifications.

The result is a smoother idle, stronger low and mid-range torque, sharper throttle response and noticeably improved acceleration from as low as 1,500rpm. The familiar hesitation below 4,000rpm is significantly reduced, giving the engine a broader, more responsive and more usable powerband.

This is not a generic one-size-fits-all chip. The programme has been developed through extensive code revisions, road testing and dynamometer evaluation on a wide range of Carrera 3.2 engines. The calibration is tailored for ROW/Euro engines equipped with SSI or performance manifolds, helping to deliver dependable gains while preserving everyday drivability.

Specifically Developed for SSI and Performance Header Applications

This version is intended for Porsche 911 Carrera 3.2 models fitted with:

• SSI heat exchangers
• Race headers
• Performance exhaust manifolds
• Free-flow tubular headers
• Modified rear exhaust systems
• Standard or mildly uprated induction systems

The revised calibration takes account of the increased exhaust flow created by these components, helping the engine operate more efficiently across the rev range.

For ROW and Euro specification vehicles, the standard programme is calibrated for 95 RON premium unleaded fuel. A dedicated 98 RON version is also available for owners who consistently use higher-octane fuel and want the calibration optimised accordingly.

What Does the Performance Upgrade Chip Do?

The chip replaces the original EPROM programme inside the Bosch Motronic DME and revises key engine management parameters.

The calibration optimises:

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

At full throttle, the Motronic system operates from its programmed fuel and ignition maps. Without revised software, performance exhaust modifications can be restricted by the original factory calibration. This chip provides the additional fuel and ignition optimisation required to make better use of SSI systems and high-flow headers.

Improved Low and Mid-Range Torque

One of the most noticeable benefits is the improvement in everyday performance.

The revised mapping delivers stronger torque from approximately 1,500rpm, making the car more responsive without requiring high engine speeds. Acceleration becomes more immediate, overtaking requires fewer downshifts and the engine pulls more strongly through the middle of the rev range.

Typical improvements include:

• Sharper throttle response
• Stronger low-rpm acceleration
• Improved mid-range torque
• Reduced hesitation below 4,000rpm
• More progressive power delivery
• Greater flexibility in higher gears
• Improved response during fast road and autocross driving

The car feels more eager and significantly lighter on its feet because the engine responds more quickly to small throttle inputs.

Smoother Idle and Improved Drivability

The proprietary calibration has also been developed to improve common Carrera 3.2 drivability characteristics.

It can help reduce:

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

The result is a more refined engine at idle and a smoother transition between closed throttle, part throttle and full acceleration.

Expected Performance Gains

Typical reported 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 portions of the rev range
• Around 10–20% improvement in part-throttle torque, horsepower and efficiency
• Stronger power delivery from 1,500rpm through to the rev limit
• Potentially greater gains on engines with SSI systems, polished intake runners and other airflow improvements

In selected areas of the rev range, particularly near 6,500rpm, gains may be substantially higher than the peak-to-peak figure because the revised calibration reduces the power drop-off found in the standard mapping.

Actual results vary depending on engine condition, fuel quality, exhaust specification, induction setup and dynamometer method.

Why Exhaust Modifications Need Matching Software

SSI heat exchangers and performance headers can substantially improve exhaust gas flow, but hardware changes alone do not automatically deliver their full potential.

The standard DME programme remains calibrated for the original exhaust system. Under full load, it follows pre-programmed fuelling and ignition values and cannot fully compensate for increased airflow.

A correctly matched chip helps by:

• Supplying appropriate fuel under load
• Optimising ignition timing
• Improving exhaust and induction compatibility
• Supporting stronger high-rpm performance
• Preventing the factory map from restricting upgraded hardware
• Maximising the performance value of SSI or header installation

This makes the chip one of the most cost-effective supporting modifications available for a Carrera 3.2 fitted with a freer-flowing exhaust system.

Potential Fuel Economy Improvement

Although developed primarily for performance, the revised part-throttle calibration can also improve cruising efficiency.

Many customers report a 10–15% improvement in highway fuel economy, depending on driving style, vehicle condition, fuel quality and operating conditions. These figures should be treated as user-reported results rather than guaranteed savings.

Benefits

Installing this OE Match Performance Upgrade Chip can provide:

• More usable horsepower
• Stronger acceleration
• Improved low-speed flexibility
• Greater mid-range performance
• Better response from SSI and performance headers
• Smoother idle quality
• Improved part-throttle operation
