What exactly is PIN 7? It is the loop around the shielded wire. What connects to it? I am new to this obviously... could not find it in the search

Hi Colin

Thanks again for your lengthy megasquirt post. We probably do need a megasquirt section and FAQ.

found the picture in yahoo searching shielded cable. Found that actual cable on eBay. They sell it in 10 foot sections.

Now I need the coil connector shown above. Cannot seem to locate that one in the states.

You just want to have the shield from the sensor wire spliced together with the shield from the cable going to your MS relay box. You should be using the shielded cable that MS sells for the EDIS crank sensor to avoid any electrical interference from alternator or other electronic "hash" producing devices. You have one piece going from sensor to plug on the EDIS controller and the piece going from the other terminals on the plug to the relay box. These two shields can be connected over to the other negative big black wire coming out of that same plug and run that to ground via the tapped hole with a ring connector on the rear part of the 318i manifold. That's where the factory grounded the stock FI system. Keep all the grounds for this system tied to one central point so you don't have any differences in potential to ground. This will cause problems with your FI.

Had the same problem finding the plu for the coil. Ended up buying a whole other system for $50 just to get the plug. Don't know why this is so hard to find. Thought that DIY auto tune would have it as they have pigtails for everything else

    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
