Ignition Starter box CDI+ 8 PIN -  Made to Order

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.

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
