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

About Ignition Switch

Ignition Switches – Reliable Starting Power for Porsche Vehicles

The ignition switch is a vital component in your Porsche’s electrical and starting system. It’s the gateway between the driver and the vehicle’s ignition, responsible for powering essential circuits — from the starter motor and fuel pump to dashboard electronics and accessories.

At Design911, we supply a full range of genuine and high-quality ignition switches for Porsche models, including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each switch is precision-engineered to ensuring smooth operation, reliable starting, and long-term durability.

What Does an Ignition Switch Do?

The ignition switch controls the flow of electrical power throughout your vehicle. When the key is turned (or the start button is pressed), the switch engages different electrical stages:

  • Accessory position: powers interior systems such as the radio or windows.
  • On position: activates the engine’s control systems and dashboard electronics.
  • Start position: sends power to the starter motor to crank the engine.

In modern vehicles, the ignition switch may also interface with immobiliser systems or electronic control modules for added security.

Why Do Ignition Switches Fail?
Over time, ignition switches can deteriorate due to wear, heat, vibration, and moisture exposure. Common causes of failure include:

  • Worn electrical contacts leading to intermittent or no power.
  • Key cylinder wear causing stiffness or sticking when turning.
  • Internal short circuits from heat or corrosion.
  • Broken return springs preventing proper key position.
  • General mechanical wear after years of use.

Symptoms of a failing ignition switch include:

  • The engine not cranking or starting.
  • Electrical accessories failing to power on.
  • The key getting stuck in the ignition.
  • Flickering dashboard lights or intermittent electrical faults.

Why Replace a Faulty Ignition Switch?

A failing ignition switch can quickly escalate from an inconvenience to a breakdown or safety risk. Replacing it restores proper electrical control, ensuring your Porsche starts and runs reliably.

Benefits of replacement include:

  • Reliable engine starting and accessory power.
  • Elimination of intermittent electrical faults.
  • Improved safety and system reliability.
  • OEM-level compatibility and performance.
