What sensor does the Pyropete 36-1 use?

Stock Ford VR.

I switched to a common Ford Hall Effect that is used as a cam sensor on Powerstroke diesels.

The 36-1 is exactly the same as what we are using on the EMC engine. We used one from an Escort.

I have that Escort wheel on mine as well with an early LS-1. If I understood you correctly you have the same sensor on the cam sensor as on the 36-1 on the crank?

No,

I removed the VR sensor that senses the 36-1 wheel. In its place I substituted a hall effect sensor. The hall effect sensor that I used is commonly used on to sense the cam position on a powerstroke diesel. I've just reused it for a crank trigger sensor.

Clear as mud?

I got a question.. could you make a ring that go on your balancer instead of the 36-1 wheel..
thinking out loud.. like the fit that you have with a flywheel and the starter gear ring that goes on one?
seems like an untapped market..

Yes you could do that, however, you'd need to make sure that the ECU software would support what you created.

We've frequently talked about using the flywheel teeth.

So I would take it that switching to "high" impedance injectors would alleviate the need for the resistors, right??

It would, and you can get pretty decent sized high impedance injectors these days.

Packaging the trigger wheel is one of those seemingly simple things that gets involved pretty quickly. First of all the wheel is like a spinning saw blade so you have to be care about what is near it or could be near it. Secondly, you have to mount a sensor in such a way that its robust enough to stay set at a particular gap and still allow for easy adjustment and replacement as well as clean wiring. I ended up using shielded three conductor wire that goes straight from the sensor plug to the EMS harness in side the car, as I had RF noise issues.

I mounted my wheel behind the damper by welding it to the steel damper spacer sleeve after opening up the wheels ID on a lathe. That's particular to my engine, but it keeps out of the way and a bit protected from road trash. I did all this with the engine out of the car which really helped.

yes I understand that, but sfi flywheels have the same pressed on rings
so why wouldn't that fly on a balancer?

Hey I am not saying dont persue it.
The balancer has harmonics going on the strap your going to put on it will effect that from a bearing issue, then from a ign point of veiw it may not like the changing clearnce remember is not solid and they may not like it at the SFI it a rotating peice.

Good point, yet how many pictures of MSD 4 magnet trigger wheels have you seen bolted to an AFI Damper. I frankly had never even thought of that, thanks Jeff.

I prefer the wheel to be affixed solidly to the crank.

Re: EFI or Carb why not both ?

The flying magnets are only four and have their own engery, I dont think is as big a deal from a pulse noise thing

I want to be sure I understand you on this one Jeff. All 429-460 BBF's have a separate dampener spacer sleeve that sets the distance between the crank gear of the timing set (belt drive in my case) and the dampener itself. It is just a sleeve that fits over the crank snout. I have an SFI approved Fluidamper, but an ATI or Innovators West for the BBF would have the same physical dimension. The spacer is not part of the dampener, isn't bolted or welded to it in any way, so in my view it does not affect the SFI certification. The whole setup has been looked at several times during tech inspection and passed.

I mention that because I don't want anyone thinking I welded something to an SFI approved Dampener, or that I recommended doing that.

I think the flywheel as trigger ring may have caused a bit of confusion. Its an interesting idea as it would increase the resolution of the signal although you'd also need a cam sensor without the -1. IIRC BBF's have 172 tooth ring gears, other brands vary of course in tooth count..

BTW we also found that the thickness of a 36-1 wheel affects the quality of the signal with different sensors. Brian Rock and Jay Brown did a lot of work on that.
