Fits:

• Porsche 911 1984-1986 3.2L  

Unlike generic ECU chips that simply alter a few fuel or ignition values, this calibration has been completely developed from the ground up. Hundreds of hours of software development, extensive road evaluation and chassis dyno testing across more than one hundred Porsche 3.2 Carrera models have resulted in a highly refined engine management programme that transforms the way the iconic air-cooled flat-six performs.

The result is a smoother, stronger and significantly more responsive engine, delivering increased torque from as little as 1,500rpm, improved throttle response throughout the rev range and measurable horsepower gains—all while maintaining factory reliability when used with the recommended fuel grade.

Whether your Carrera is completely standard or fitted with a sports rear silencer, this bespoke calibration is designed to maximise the engine's true potential.

Specifically Developed for ROW / European Specification Cars

This version has been calibrated exclusively for European and Rest of World (ROW) Porsche 911 Carrera 3.2 models.

Unlike universal chips, the calibration has been optimised for:

• ROW / European engine specifications.
• Standard rear silencer.
• Sport rear silencer.
• Bosch Motronic DME management.
• Factory engine components.
• Mildly modified engines.

The standard programming is designed for 95 RON premium unleaded fuel.

For customers regularly using 98 RON fuel, an optional dedicated calibration is available to extract even greater performance while maintaining safe engine operation.

Developed Specifically for the Porsche 3.2 Carrera

The factory Motronic calibration was engineered to satisfy worldwide emissions legislation, varying fuel quality and production tolerances. While extremely reliable, it leaves considerable performance untapped.

This OE Match Performance Upgrade Chip completely re-engineers the original software by optimising:

• Ignition timing maps.
• Fuel delivery.
• Part-throttle fuelling.
• Full-load enrichment.
• Torque delivery.
• Throttle response.
• Idle control strategy.
• Deceleration characteristics.

Every calibration has been extensively refined through road and dyno testing to produce performance improvements that are immediately noticeable from the moment you drive away.

Noticeable Improvements in Everyday Driving

This upgrade transforms far more than peak horsepower.

Owners typically notice:

• Smoother idle quality.
• Virtually eliminated idle hunting.
• Reduced sub-idle RPM dip during deceleration.
• Reduced exhaust popping and backfiring on overrun.
• Sharper throttle response.
• Stronger acceleration from low engine speeds.
• Improved flexibility in everyday driving.
• More immediate engine response from just 1,500rpm.
• Elimination of the familiar flat spot below 4,000rpm.

The improved torque delivery gives the impression that the car has shed significant weight, making the Carrera feel substantially more eager throughout the rev range.

Proven Performance Gains

Typical gains include:

• 6–8% increase in horsepower and torque across the powerband.
• Approximately 12–16 bhp increase on a standard engine.
• Around 20 lb-ft improvement in torque through much of the rev range.
• 10–20% improvement in part-throttle torque and engine efficiency.
• Significant gains approaching the top of the rev range, with improvements of up to 25–35 bhp around 6,500rpm under certain operating conditions. Stronger acceleration from 1,500rpm through to the rev limiter.

Cars fitted with additional modifications such as polished intake runners or a performance exhaust system may achieve even greater gains, as the revised ignition and fuel mapping allows the engine to make full use of the increased airflow.
