Rear distributor questions

creats the signal which could be sent to a standard MSD 6 box. The MSD box then tells the coil when to fire and so on. You would probably have to switch over to a standard MSD or similar coil and mount it back on the firewall.
I am very interested in giving this a try, but I am looking for options on getting the stock intake machined to accept the distributor.

You need the signals from the opti to control fuel with the stock ecm. Or you could use the 96-? vortec distibuter with an after market ecm.
If your going carbed you could use any dizzy but why would you do that?

A standard rear mount distributor creates its own signal. Ohh you must have a MSD ignition box for this to work. The distributor

You can go with a rear mount dist for the ignition yes, but just like with the delteq, ltcc, etc you still at least have to retain the optical sensor portion of the opti for the low res pulse.
When I stated that it "doesn't work" with the stock PCM, I was referring to completely eliminating the opti, since that was the question. ggk asked 383LT1S10 if his setup (which completely gets rid of the opti) worked with the stock computer, and the answer is no (he uses the megasquirt).

Nope, I an many others have tried every possible solution with no luck. The only possible solution would be to create a low res pulse generator and have it sync up with engine speed somehow. Is it doable? Yes, but far too much hassle just to keep the stock pcm. For the hassle you can go with a aftermarket EMS and be one step ahead.

Information regarding rev limits on EDIS is hit and miss really. Some claim to have hit a ceiling at 6,000rpms but it's never been documented other than someone online saying they know someone who had that problem. The other EDIS conversions I've done and helped with have revved to 7,000+ just fine. Usually any problems are caused by using aftermarket coils with too high of resistance and overloading the EDIS module.

I'm not talking about the ignition signal. I'm referring to the low res pulse aka cam position signal. The stock computer needs that to control the injectors properly, and there is no way to do it other than with the opti.

Notice I said "my recollection". Did I say "You're dead wrong, and that's how it is!"? No, I didn't. So you being a complete *** was not even merited. Unless you're trying to impress CapriceMgr, then I'm sure he'd be proud.

acctually he might ne right about it working. cause on the 4.3 it uses it as a crank sensor. it prob wouldnt be hard to emulate the cam sensor or even install one int the timing cover.
i am merely running a gm 95-7 pickup truck distributor, lol! nothing fancy.

i have been looking around but there isnt any real info ive found. what ive found is that a est distributor gives a crank position, but i have found a trouble code that is for a cam position sensor. im just trying to find all this out.(if it isnt in the distributor it might be reall easy to attach a low res reluctor wheel to the opti and get rid of the rotor in the opti)

where is the crank sensor in an lt1? in the opti on the crank?
the cam sensor is the low res pulse(since they are from the same era i bet they are the same x number(4x / 2x))
last night i found a site that has a crank sensor kit but idk if its good.

Anyways, I don't know if the 92-95 use the Opti as a cam and crank, or just cam sensor, but the 96-97 have their own crank sensor.
