Programmable Distributor, 0.237.306.001 for 911SC

Product Description:

New Programmable 123 Ignition Distributor
Arrives pre-programmed to replace Bosch 0.237.306.001.
WARNING: Programmed only for stock '78-79 USA 911 motors!
Professional installation is recommended.

Run a new distributor on your classic Porsche!  This distributor has the design character of the original, but with modern electronics. The 123 distributors have been around for over a decade, but they were challenging to set up properly for the 911SC. Until now!

Comes pre-loaded with our exclusive programming for your stock engine. Our programs for each year and sub-model were developed and tested by a Porsche-trained mechanic, engine builder, and ignition specialist with 34 years of experience. 

This distributor is pre-programmed to replace a Bosch 0.237.306.001, which was factory equipment on 1978-79 Porsche 911SC 3.0L engines in the US. Verify your engine code matches 930/04, 05, 06, 15. Please note that any changes to the stock programming are made at your own risk.

For modified 911 engines, a qualified, insured mechanic should be employed to adjust the programming to the engine. Incorrect setup or installation can result in severe damage to the engine and distributor.

When properly re-programmed, this distributor can also be set up for 1980-83 stock 911SC engines and 911SC Euro engines. Never attempt to use this distributor on a 930 / turbo engine!  An Apple or Android App allows for wireless adjustment of the ignition curve and provides an electronic dashboard. Range is 500-8K RPM. Vac can be programmed up to -20 / +20 degrees. Max crankshaft advance 40 degrees. Other key features include rev-counter, anti-theft PIN code, real time tuning, vacuum advance, and soft rev limiter.

This distributor does not use the Bosch “green wire.”  Instead, we include a male plug that will connect the distributor’s trigger wires (green signal wire and brown signal ground) to the harness after the installer trims the wires. We also include a piece of shielding for the distributor’s green trigger wire. You may use this distributor with our “6 Pin CDI Wiring Harness, for 123.”

Manufacturer Information:

Aftermarket
Our founders have worked on Porsche cars for decades. They've tried most of our aftermarket products first hand on real cars. Some parts are no longer made by an O.E.M company, or the price difference between genuine and aftermarket has become so large that it makes sense to take the savings. If you have any questions about an aftermarket product, please contact us.
