Inline 6 on a 0411 pcm

I see the error in my thinking.

I had faith you'd figure it out, you're a pretty smart guy.

Another Idea similar to how DUI Distributors makes the HEI Distributors for the IH V8 engines. Basically, DUI adds a spud shaft / spud housing and an IH gear assembly to an "Off - The - Shelf" Chevy HEI distributor. Perhaps a similar idea will allow an "Off - The - Shelf" Vortec V6 distributor with 1x CMP to be retro fitted to the Jeep Inline 6? Perhaps a custom "one-off" Jeep Inline 6 spud shaft / spud housing and Jeep gear assembly added to the Chevy V6 distributor?

That's what I have in mind. I'm running a big cap HEI that I did that to. But you can buy the big cap distributor for the jeep in line 6.

So I know I can modify a V6 distributor to work. But jeep makes this for the later model 4.0 engine. To bad the 0411 won't do coil near plug.FD39_TOP_P04__ra_p.jpg

Seems like the next step is a 3x CKP.

Well I spent a few min. looking at the reluctor angle compared to the balancer angle at TDC. It looks like it should be a simple thing to do. We'll see.

I don't know if either a V6 or V8 using the '0411 with a distributor mounted CMP will run without a CMP signal, that theory of operation will need to be tested.

What I've learned from the dual trigger distributors I've built is the alignment between CMP / CKP is CRITICAL. If the distributor mounted CMP is not accurately aligned with the CKP, the engine will not start.

I don't know if you can just "unplug" only the CMP on a V6 like you can on a V8. I just don't work on those like I do the V8s. Is there a separate plug on the distributor for only the CMP signal?

The distributor mounted CMP has it's own 3 pin plug.

Been there, done that.

Dave will the factory crank sensor pickup aluminum or just steel?

[dave w]

Aluminum won't work, it needs to a ferrous metal.

I use Mild Steel.

Stainless steel won't work.

Thanks I found a piece of an old skid plate from a cj5 I used to have.
I think it'll work nicely.
So it needs to be magnetic.

[dave w]

The sensor has a magnet inside, so the trigger wheel needs to be made a ferrous metal.

[Thorwon]

Well I got the reluctor made and mounted today. Now if I can get the sensor mounted and lined up I'll start running wires.

A little more progress.
Can anyone tell me what the gap should be between the sensor and reluctor?
