Using fuel pump cam lobe for a trigger

Too fast was l.

But yeah, this is nice solution for a cam trigger on B230. Air gap is little pain to get right, so adjustable (w threads) sensor is more forgiving with design.

I made first prototype of cam with angle grinder. Second one was made first by milling and then turning the cam to get off-centric off. With that one air gap was too big and small adjustment of braket was needed.

This is for VW air-cooled engines, but suits also B20 and B30
Similar to Compu-Fire DIS trigger for VW or most any 4 cyl Bosch distributor. I had that system adapted to B21

Well, they were on sale, so I got one of the CB Performance cam sensors for VW. I can confirm they fit with the B20 distributor drive.
A single hall sensor for cam. Plan to use a DIY 36:1 crank trigger wheel with a hall sensor for sequential ignition with LS coils and Microsquirt.
 
what 36-1 trigger wheel/spacer/pulley are you using? And what sensor? My engine is on a stand, so if you wanted to, I could engineer a sooper bichin billet bracket for your sensor setup.
 
Like this, maybe? Sold out and pricey
 
Per the manual, 9 teeth before the gap at tdc, so 9/36=90/360 and the cam sensor aligned
I’ve got a 36-1 toothed wheel. Let me see what I can get going for a pulley. I’ve got one of dales edis single groove pulleys and I think it’s something I can work something out for you
