All, what wheel should the 280zx turbo wheel fall under? i was thinking nissan 360, but it doesn't really fall into the discription.

Here's a picture I found online.

"Unsupported"

Maybe best to add a 36-1 trigger wheel and blank off the distributor.

Maybe I can set it up to read the inner slots, as a distributor?

On the other hand, I do have the chopper wheel from the 300zx. It's probably unsupported. It does have a unique inner slot.

If there's a sensor for both outer and the inner single on the 280zxt wheel, maybe it can be a "dual wheel" setup. Sounds like that description to me.

Did you check the wiki before posting?

It's a Nissan 360 or variation of). It's in testing.

If you want proven setup change it.

Pretty simple.

YES, I did... that's why i wrote... " i was thinking nissan 360, but it doesn't really fall into the discription." How do you think I came up with that conclusion?
And just because it's not on some wikipage, that doesn't mean someone hasn't done it... I thought this forum was about knowledge sharing.

It's not supported. I said that from the start.

As per the wiki there are many variations.

From your picture I cannot tell if it is one of the variations but it is clearly not one that is listed as supported.

Those style wheels are NOT easy to work with.

If you want to use speedy then swapping it out or adding a crank sensor will be the easiest, fastest and best supported option.

If you want to actually get it working with that wheel then you will require a 2 Channel oscilloscope ideally so you can record your current sensor output and then mark up on that output where TDC of cylinder 1 is etc.

As you haven't provided any info about what you are doing I gave you the short answer.

I did think about that. My understanding is the 2nd signal can only have one slot per rev. With my setup, I should try to running it as a distributor. I haven't focused on this for several weeks. I'll dig into it some more.

If you block all but one secondary slot, you should be able to run it as Dual Wheel, 180 teeth primary at crank speed, and 1 cam. Stick some thin tape on there to test perhaps.
