distributor as cam sensor options...

[Chickensoup]

hi there,

so when running sequential, you need a cam sensor of some sort, or a way to tell the ecu where #1 piston is at... duh

so, what kind of distributor can i use? i see that the late 2.0 type 4 distributors already have a hall sensor, but will the body and shaft fit into a type 1 case? if so, then can i just remove 3 of the windows?

or, can i take any distributor, strip it, lock it, and put a magnet on the rotor and make a custom cap for it, that is drilled and tapped in the right spot for a vr sensor, that way, when the rotor is pointing at the number 1 position, the sensor will send a signal to the ecu?

ive also seen someone add an internal magnet on the cam gear and drill and tap the case for a hall sensor. does anyone have any experiance doing so.

i saw this here,

im also open to other ideas, but i would like to use a distributor that has the same shaft as a type 1 so it will drop right into the current hole.

thank you
aiden

Do you have a 1979-83.5 aircooled bus/van distributor with all the fixin’s on the shelf??

If you just grind three of the four lobes off the points cam it would be a mechanical hall sensor. Can be wired to produce a 0-12 volt or 0-5 volt signal.
THe rest of the distributor could be used as....a distributor.
Using points to run modern electronics.....weird eh? but I do it all the time. Works good.

or
Compufire with one magnet?

[modok]

40 or 60 ohm resistor between 12v ignition power and points.
When points are open, 12 volts
when closed, 0 volts
similar to this

Our 5.9 / 360 Magnum died in the driveway last week. I did a lot of YT and found scannerdanner who has some great trade school vids on troubleshooting modern cars. The Dodge uses a "square wave, 5 volt, pull down, hall effect sensor for the cam position sensor in the dist and also for the crank position sensor. You CAN test them with a volt meter but a scanner is best.

I looked for pics of the inside of the dodge dist. The rotor is basically solid for 1/2 of the diameter then open for the other half. I was expecting windows. I guess the leading edge of the rotor is the signal. So it really is determined by what your computer can be programmed to read.

BTW, after testing the cam position sensor and crank sensor both were good and the 5 v bus was not shorting out so I ordered a rebuilt computer and it fired up instantly. WOOTT !!

Here is a vid with pics of the inside of the dodge dist.

Yes you could use a compufire, I would still add a resistor as a "dummy load".
It would just go across the two wires.
the nice thing about that.... is it could be 100% reversible.

Tho, I like the simplicity of the points idea.
They last an incredibly long time if just used as a 'sensor" instead of handling all the power.
I've been using the same set of points since 2012, and they weren't new then.
5-6 days a week.
You could also use maybe the sensor from a crane xr700 ignition kit, which is an optical trigger, I'll have to look that up.... but I think it would be even easier and maybe cheap cause nobody likes those.

[modok]

Yeah just grind em down.
Good question.... i don't know for sure...... maybe nobody does know, but I THINK
IF the computer is equally capable of reading a hall or a VR sensor, I think it will be able to work fine with points.

Could use Compu-Fire module with 3 of the 4 magnets removed, leaving only the one magnet for #1 TDC ...
