123 Distributor


Recommended Posts

I just purchased a 123 distributor and new “blue” coil from IE, and wanted to see if anyone had any tuning recommendations that might accommodate my set up. 
currently working with a 32/36 Weber. 184 degree cam and everything else is just about stock. 

I'm still waiting for the distributor to arrive but in the meantime I have been checking out the 123 app and am pretty impressed with the functions available.


Any suggestions would be greatly appreciate!

When you install it and rotate the body to light the LED as instructed, before you load an advance, write a "tune" to the dizzy, that is a flat line through the RPM range to 8000. 12º is a good number. #1- Use a digital timing light set to that number(12º) and confirm that the TDC mark on the pulley lines up with the mark on the front cover, lock it down. #2- Since the tune is a straight line through the RPM range, with the timing light still on the pulley, slowly raise the RPM and verify that the mark stays at TDC. This will verify that the dizzy is maintaining the timing you give it. Once you know the dizzy is working correctly, replace the flat line tune with one from the many suggestions given on the forum. Have fun with it.

You shouldn't be using an internally resisted Blue coil with a 123, they recommend a Bosch red coil (or equivalent) and no ballast resistor. 


This is from the 123 site.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
