Yesterday when I was taking pictures for my Clutch-Line install thread, I disconnected the vaccum line to the MS which was in the way. When I started the car this morning... it ran like ****. It was super rich as it was in the 1500rpm/~0 cel on startup. I was running 10ms on pulse length and it was spitting gas out the tailpipe. I couldnt' figure it out right away so I drove the truck.

I get home this evening and discover the disconnected line pretty quick... and since it's warm now, I start messing with my idle. First is to double check timing... HOLY ****, HOW DO I CHECK THE TIMING WITH NO SPARK PLUG WIRE?!?!? As it turns out, just putting the inductive pickup on the COP harness worked like a charm. So, I learned something new. My timing was perfect and I messed with some warmup values and some idle timing. It idles a little better now. That's all.

 

If you do have issues, like at the dyno, stick a plug wire in the end of the cop and use it as an extension cable for the coil. The inductor can go around the plug wire.

 

yeah on my sr20 i was able to just put the gun over the whole harness...... and the gun was from the 70's.. i was impressed

 

timing light wouldnt work with my cops, so i threw my stock coil pack on it, since it was sitting there. otherwise, use #4 wire and pull #1 out.

fwiw, inductive pickup works on dyno.
