Ignition Starter box CDI 3 PIN. Porsche 911 1965-77 Classic Retrofit ❭ 91160270700

- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

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.
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 Classic Retrofit 3-pin CDI+ ignition unit is a direct replacement for Bosch CDI units used in the classic Porsche 911 from 1969 to 1977. Extensive development and rigorous dyno testing has proven our CDI+ unit to be a major improvement over the original Bosch CDI, with improved torque right across the rev range.
CDI ignition was originally fitted to a great many European sports cars of the 1970s and 1980s, including Maserati Ghibli, Alfa Romeo Montreal and are popular with BMW 3.0 CSL racers. Our CDI+ is a great upgrade for all of these applications.
