Another way to do it might be to "trigger" an IC "divide by 2" off the points and feed that to the ECU. Hummm

Ken


I thought of that earlier and it would be even better than my current "fix", but I don't know electronics that well and once I got to the flip-flop circuits I got a even more confused (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

the logic is not too hard to time it with the ignition event:

1 = trigger Rt
2 = no trigger
3 = trigger Lft
4 = no trigger
1 = trigger Rt
2 = no trigger
3 = trigger Lft
4 = no trigger
etc...etc....

I still might look at that path, I just need to do some more homework on the subject.......I just wanted to prove that it can be done, and I do agree with you, I think there is a better method by using the points (mech or elect.) than with the optic sensors

You say mickey mouse engineering.. are those optical sensors out of an old fashioned ball-type mouse? (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

no...I bought those brand new (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

I hadn't really thought about taking about an old mouse for the parts, but now I'll have to take one apart (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

You're a creative guy Mike, but is this a solution without a problem? Stock dizzys work fine, replacements are available...

So why the need for this other than its new?

some people would like a newer or more modern distributor???

at least for our region PCA, the ignition is free to upgrade, yet the FI must remain stock....with the Mallory and MSD distributors, they can be tailored with different features such as non-stock advance curves. The new distributors also have larger diameter caps and rotors which in theory should help reduce spark scatter with more powerful/aggressive ignitions..
I can also now run a CDI box that should just be plug-n-play.

The original engine wiring harness plugs right up...the new ignition can be removed and replaced with the original with no signs of tampering...so your wiring harness will work perfect (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)


granted, most people that want or need a better ignition will have carbs or an aftermarket FI, this was done mostly to prove an idea I had and due to me wanting to run the Mallory ignition setup while retaining my D-jet (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

I can tell you the car does start and idle better, but I'm sure it's mostly due to me getting rid of the points and going with an electronic ignition.....

I wouldn't call it mickey mouse engineering! Pfrototypes always look questionable! Good work! (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

Hey Mike, How about a cheap LSD or a way to modify the 915 or G50 ones to fit in our transaxle. That would be cool!

Mike, I'm lurking in the background awaiting final setup. This sounds great. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) I run two '73's with D-jet. Love to see this work. Our SCCA rules allow for any distributor, but don't mess with the fuel injection or your up a class or three!
Keep us posted.

GARY,

Call Paul - you can buy replacment gears with the "coarse spline" that will convert a 915 LSD. He cloned a ZF and has all the internals - disks & spacers.
