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.

Basic Unit:

The basic unit is a plug and play replacement for the Original Bosch CDI. It will work with the existing distributor without modification and still uses the weights and springs for the advance curve. It is pre-set at the factory (to your specification) and has the following features:

-Hard RPM limiter.

-Soft RPM limiter.

-Double spark at all RPMs

-Shift Light output

-Tacho calibration

-Upgradeable through firmware updates (at one of our specialists)

-The following parameters can be adjusted using the hidden ‘jog wheel’.

-Hard RPM limiter.

-Soft RPM limiter.

-Shift light RPM.

-Tacho calibration.

The basic unit can be upgraded to an advanced unit at a later date by one of our specialists.

 

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
