Megasquirt Using both Zeal conditioners
You dont use both of them when using a v3.0 board.
the board has one built in, and the zeal daughterboard will provide you two extras, so all you need is one.

I know that is the general configuration. I need to apply the board as I am describing. My primary vr conditioning circuit has failed and rather then fixing it, I would like to just use the extra on the zeal board.
Tsel and tachselect.
Remove the jumper to tachselect and remove the jumper to tsel.
I think thats the way to go about it. I asked around and the guys here said thats the right way to go about it.

Ok, im gonna make this really easy for ya.
Do not bridge tach select and vr in.
Do not bridge tsel to anything.
Vr1 Input on the zeal goes to TachSelect. VR1 Output on zeal goes to Tsel.
Vr2 Input can be used on any unused pin on the 37 pin connector. VR2 output goes into JS10.

Yeah, its in there. i actually pulled a board and looked at the schematics and deduced what should be done.
Sometimes, engineer speak is hard to understand. not saying it is engineer speak or you needed it dumbed down, but maybe someone else would need the information quickly on the forum. here is the excerpt from the zeal documentation.

If you wish to use the VR1 circuit, it's a good idea to bring the negative VR wire in on an unused pin. For example, if you are wiring the VR sensor to pin 29, you would connect the negative (lower) VR1 terminal on the Zeal Engineering Daughterboard to IAC2A on a V3.0 or V3.57 board, or X13 on a V2.2 board. On a V2.2 board, remove D5, R10, D8, C12, U4, C11, and R11.
The upper (positive) VR1 terminal connects to different points depending on the board.
V2.2 board: Unbanded end of D5
V3.0 board: TachSelect
V3.57 board: Pin 2 of JP1
Connect VROUT1 to the following pin:
V2.2 board: Bottom end of R11
V3.0 board; TSEL
V3.57 board: Pin 2 of J1

Yeah, I have been using MS for almost 4 years now. Marketing the controller and installing it on a wide range of vehicles. I wanted to confirm where the v3 board VR circuit ended.
I was going to post that from the guide. But I just finished and everything works so I am happy. I do not have a scope so diagnosing circuits is harder then just replacing them.
