besides machining the ring, we would need to have the notches machined out as well? what kind of sensor would be needed? OEM?

"ring" = toothed ring. It'll likely be cheaper to water-jet it vs. lathe/mill.

The sensors will likely be the same ones discussed earlier in the thread. Cost and availability will determine the actual sensor, but there are a lot of reluctive magnetic sensors out there.

Another challenge will be to get connectors that the connectors that normally plug into the dissy will plug into, such that there isn't any wire-cutting involved. First things first, though.

this is where i picked up some OBDII stuff when i repinned a LS harness, they should have new weatherpack style connectors for the dissy units cheap, I'll check around the book i have and see if they come up, we would want the two connectors for the module correct?

Here's the measurement I'm after:

My lame attempt at a cardboard prototype of the ring:

This is how mine is setup, except the reluctor ring is welded to the backside of the crank pulley (about midway from the belt to the balancer) instead of the balancer. I suspect that this would give you considerably more room to work with. I've tried to get in there to get a picture, but it's nearly impossible to get in there to get a decent picture of it. I might try using my friends camera on his phone, as it would be easier to clear everything.

I'm running $59 with the DIS and it works great. The DIS was already on the truck when I got it, but I setup the $59. It was pretty simple to get it the DIS and $59 to work together, so that should be the easy part.

Your pics would be a great help... Maybe you could get a better angle/look from underneath?

I'm also curious about where/how the coils mount, and whether the dissy was replaced with something else.

Thanks,

Yeah, we need mating connectors for the dissy side and the plug in connectors for the module side.
The module side connectors are easy, they have lots of male connectors for repair purposes.

The 2-pin mate for the distributor I've seen before, so that's not a big problem. The other one isn't as common to find in a female. Mouser would be the place to look.

The only other connector we'll need will the the one on the sensor itself, which will likely be a ford style connector, unless we can find a better part from the GM bins. GM liked to do "in-block" sensors, which are a bit more difficult to mount. The Ford sensors have mounting tabs built in.

Been looking at sensors... this one looks really good:

And it isn't too crazy expensive. There are cheaper ones, but they don't have as good of a mounting option.

Sacrilegious! A FMC part on a SyTy?
Or is that the ultimate disrespect? Beating them with their own parts.

I have a SMP catalog from last year with a picture listing of all PC sensors. I'll see if I can get it scanned in next week (just in case there's a better alternative).

Aren't the steering boxes Jeep/Chrysler already?
Beating them with their own parts - sounds like a subplot to a zombie movie.

Pictures of options are good. The Summit site sorts what they have by price... gives a fairly decent idea of costs.

I can tell you the coils on sytyaddict's sy are mounted where the distributor was, its very stealth setup and I looked at the engine for over 45 min before even figuring out it was even a DIS.

This *may* be the 4-pin one... would have to get one and try it.

Bringing this back up because I was intrigued by the accel dual sync distributor, and wondered if we could just use the sensors instead of a true crank sensor...

It was brought up before and it can't be used. Cam runs half the speed of the crank and the toothed ring is different. We need a 7 tooth wheel and the dualsync uses a 36 tooth wheel, I think. I wish it were that easy. :(

Couldn't you make a new wheel for a dual sync dist? One with twice the marking required to compensate for the half speed?

It would be great if someone (Hint:sportmachines) would want to pick this up....

Just in case anyone else wanted to do some reading. Z ski got me thinking last night and I looked up EFI Connectrions

58x Crankshaft Reluctor
The EFI Connection 58x system satisfies the GM Gen IV ECU's crankshaft signal with a 58 tooth crankshaft reluctor wheel that installs within the SBC/BBC timing cover. Made of billet steel, our crankshaft reluctor wheels are the highest quality pieces available.

The crankshaft reluctor wheel adds thickness between the crankshaft timing sprocket and crankshaft balancer. Late SBC/BBC engines (Vortec) are equipped with balancers that are shorter than early SBC/BBC balancers to accomodate for the thickness of a crankshaft reluctor. Our crankshaft reluctors will require the use of the late SBC/BBC balancer or you may machine down an early SBC/BBC balancer to avoid crankshaft pulley misalignment.

COULD IT REALLY HAVE BEEN SO SIMPLE???

I hope it ends up being that simple!!! I got a good chunk of $$$$ into my DIS system and hope it works... I might throw a hand grenade in the cab if it doesn't work :kboom:
