Ok, so say I wanted to do a 36-1 with a vr trigger. I would build the VR Circuit as per step 51 of the megamanual, and configure my jumpers as per Joes thread here: https://www.miataturbo.net/showthrea...t=20241&page=2
I would not have to remove any of the previous mods on my board because they would be disabled by the jumpers, correct?
One last question is which pins would I wire the VR sensor into on the megasquirt?

Basically, you will build the complete VR circuit, and then set the following jumpers:
TachSelect - VrIn
VrOutInv - Tsel *or* VrOut - Tsel
The decision as to whether to use VrOut or VrOutInv depends upon the polarity of your VR sensor wiring, which is impossible to determine without an oscilloscope. So you'll have to just experiment and see which one works. Alternately, you can set the jumper to one or the other and then try flipping the wiring of the VR sensor itself. Same deal either way.

This is just the info I'm looking for, I'm glad I gained some understanding of VR vs. hall sensors in the process. I plan on trying this out after I finish my LNC 1.6 build as that wheel will be pretty much bolt on to that engine, not so much for my SN thats in there now.
Will I need to do anything else to get a tachometer to work on my 1990?
