    Yep... "double pulses" is not the way to go. The original 60 deg V6 DIS wheel looks like the one Six_Shooter posted previously.


    It turns at crank speed where the distributor turns at 1/2 crank speed, so you'd have to make a wheel with 14 notches instead of 7 and they'd have to be mirror images of each other. Here's a good description under "Magnetic CKP." https://books.google.com/books?id=0S...0notch&f=false

    14 signals on the dizzy is what I was trying to accomplish. Seems easier than swapping cranks. But then again, 15 minutes to swap out a balancer sounds easy too. Dang! Thought i was on to something!
    Sooo......what you're trying to say is... there's a reason it hasn't been done. ;)

    I think it may have been tried once back in the day. There were some old posts from a guy "tedscj" on diy-efi. IIRC he was trying to use a GM ecm on a Jag engine. I believe he made a distributor with a double notched wheel. Back then we didn't know enough to make it work properly but he gave a a dang good try.

    I built a wheel and adapter for DIS on my Toyota engine. I put mine in front of the pulleys. I have to remove the sensor to change the belts but it's not a big deal.
