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.

The Classic Retrofit 8-pin CDI+ ignition unit is our direct replacement for Bosch CDI spark boxes used in many classic Porsche race cars, including the 911 RSR, 934, 935, 917 and 962. It was also fitted to the early 3-litre 930/911 Turbo and other race cars of the period, including BMW CSL.
Fitted in a replica CDI case, this unit is a wonderful upgrade for vintage racers where originality and reliability are equally important. It has been tried and tested in many vehicles, including several Le Mans winners still in circulation.
The Classic Retrofit 8-pin CDI+ unit requires no modifications to the original wiring loom harness or metalwork and is 'plug and play'. The soft and hard rev limiters can be programmed via a laptop. All CDI+ units have a 48 MHz microprocessor onboard to control ignition timing.
It is a little-known fact that the 8-pin CDI boxes provide better regulation over the output voltage than the 3- and 6-pin units. Our redesigned electronic system brings the original voltage regulation concept bang up to date, not just by providing even better regulated output across all of our CDI units, but also by offering true dual-spark output at a 400us interval that truly makes a difference to combustion, right up to 10,000 RPM.
Please note:
This part is on special order terms. It will be made to order and it is not a subject to cancellation or return if not required.

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

Ignition Control Units – Precision Spark Management for Porsche Performance
Ignition control units (ICUs) are vital components in Porsche’s ignition systems, responsible for controlling the timing and strength of the spark that ignites the air-fuel mixture inside the engine. Working in conjunction with sensors, ignition coils, and the ECU, these modules ensure efficient combustion, smooth acceleration, and reliable performance across all driving conditions.
At Design911, we stock a complete range of genuine and high-quality ignition control units for various Porsche models. Each unit is precision-engineered to deliver accurate ignition timing, improved combustion efficiency, and long-term durability — keeping your Porsche performing at its peak.
What Do Ignition Control Units Do?
The ignition control unit regulates spark timing and coil
charging, ensuring each cylinder fires at precisely the right moment. Key
functions include:
- Managing
ignition timing for efficient fuel combustion.
- Coordinating
signals between the crankshaft sensor and ignition coils.
- Optimising
engine performance under varying load and speed conditions.
- Improving cold-start reliability and overall drivability.
- A well-functioning ignition control unit is essential for maintaining power delivery, throttle response, and fuel efficiency in both classic and modern Porsche engines.
Why Do Ignition Control Units Fail?
Ignition control units operate in harsh environments,
exposed to heat, vibration, and electrical load. Over time, these conditions
can lead to failure. Common causes include:
- Thermal
stress from prolonged heat exposure.
- Electrical
overloads or short circuits.
- Corrosion or damaged connectors.
- Component
fatigue from age and vibration.
- Voltage spikes from faulty coils or sensors.
When an ignition control unit fails, it can cause engine misfires, starting difficulties, poor acceleration, or complete ignition loss.
Why Replace a Faulty Ignition Control Unit?
A failing ignition control unit can lead to inconsistent performance, reduced fuel economy, and damage to other ignition components. Replacing it restores ignition precision, reliability, and overall engine performance.
Benefits of replacement include:
- Accurate spark timing and improved combustion.
- Smoother acceleration and throttle response.
- Reduced misfires and emissions.
- Reliable engine starting and performance.
All ignition control units in our range are designed with advanced electronic circuitry and heat-resistant housings, ensuring precise signal processing, stable operation, and long-term reliability for all Porsche models.
