Ignition Starter Unit CDI 6 PIN.
(Bosch Ref 0227300004)

Classic Retrofit replacement CDI+ ignition offers you bespoke modern electronics in a standard looking package. The CDI+ unit requires no modifications to the original wiring harness or vehicle metalwork and is 'plug and play'.

The CDI+ is a direct replacement for the 3 pin and 6 pin Bosch units fitted to Porsche 911's between 1969 and 1983 (and turbo models to ~1988). All CDI+ units have a 48 MHz microprocessor onboard to control ignition timing.

Advanced Unit:
The advanced unit allows the adjustment/tuning of the ignition advance curve and other features by plugging in a laptop. This can be achieved by 'overlaying' a curve on top of the distributor weights/springs curve or by locking the distributor and replacing the curve completely. Either way, you can unlock the true potential of your engine by adjusting fuelling and having the ignition curve to match.

The CDI+ has all the features of the basic unit but allow more flexibility in adjustment:
-Fully programmable ignition advance curve.
-Hard RPM limiter with adjustable ignition cut schemes
-Soft RPM limiter with adjustable ignition retard
-Launch RPM limiter
-Double spark at all RPMs
-Max RPM tell tale
-Shift Light output
-Clutch pedal input
-Tacho calibration
-Upgradeable through firmware updates

Fits:
Porsche 911 1978-83
Porsche 930 3.3L 1978-89

6 Pin CDI Harness

This harness is designed to be a stand alone replacement wiring harness for the 911SC models using the 6 pin CDI system. Until now the only way to replace a damaged ignition harness on the SC models was to replace the entire engine harness. This is very expensive and time consuming to do. We have designed this harness to allow the mechanic to just replace the wiring harness that controls the ignition function of the vehicle. The harness will plug directly into the CDI Box, The Ignition distributor and coil. The only two connections that will require some plug dis-assembly are the 12V ignition connection at the rear fuse panel and the tachometer signal wire at the 14 pin plug connector. Both of these wires come with the correct connectors installed on the wires.

OE Match Performance Upgrade Chip – ROW/Euro Spec with Standard or Sport Rear Silencer

Unlock the hidden performance within your ROW/European specification Porsche 911 Carrera 3.2 with this OE Match Performance Upgrade Chip, specifically developed for Bosch Motronic DME-equipped cars fitted with either the standard rear silencer or a sport rear silencer.
 
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.

Optimised for Performance Exhaust Systems

Many Carrera owners install sports silencers expecting significant performance improvements, but the factory DME continues to use conservative ignition and fuelling maps.

This Performance Upgrade Chip is specifically calibrated to complement:

• Standard rear silencers.
• Sports rear silencers.
• Improved exhaust flow.
• Freer-breathing intake systems.

By optimising both ignition timing and fuelling, the engine is able to fully exploit these modifications, resulting in greater performance than exhaust upgrades alone.

Improved Fuel Efficiency

Performance and efficiency do not have to be mutually exclusive.

Thanks to improved ignition timing and more efficient part-throttle calibration, many owners report highway fuel economy improvements of approximately 10–15%, depending on driving style, vehicle condition and operating conditions.

Benefits

Installing this OE Match Performance Upgrade Chip provides:

• Increased horsepower and torque.
• Improved low-speed flexibility.
• Faster throttle response. Smoother idle.
• Better drivability in everyday traffic.
• More responsive overtaking performance.
• Enhanced compatibility with sports exhaust systems.
• Improved engine efficiency. Potential improvement in motorway fuel economy.
• Greater enjoyment every time you drive.

Installation Recommendations

Professional installation is recommended.

Before installing the Performance Upgrade Chip, Design911 recommends ensuring:

• Ignition components are in good condition.
• Spark plugs are correctly specified.
• Fuel injectors are clean and operating correctly.
• Fuel pressure is within specification.
• The airflow meter is functioning correctly.
• There are no intake air leaks.
• Valve clearances are correctly adjusted.
• Oxygen sensor (where fitted) is functioning correctly.
• The engine is fully serviced.

Selecting the correct software calibration for your fuel grade and engine specification will ensure maximum performance and long-term reliability.
