Im using the ms2 and was curious if for spark output mod i followed all in this picture i found for ms1, but the description for ms2 is the same without having a picture

So i guess my question is do i just do the resistors on the right or do i do the other 3 wires/resistors as well

There are several ways to make the spark output mod. The one on our page works with the settings on our page.

Ya i have found some other options. At the time of posting this i had been researching for 2 hours and felt like i was doing circles lol. Im actually probably going to go with the quad spark. I figure it will work nicely when i switch to toyota cop

So just to let everyone know this is my first ms build. I am building ms2 extra and having little difficulty trying to figure what to do with spark output and need just some questions answered. Also, the miata i have is a 94 1.8
Btw Im trying for sequential spark output.

So my first question i guess is should i try running toyota cop from the start or just deal with wastegate first?

Second, clarification that the toyota cop have an ignitor in them and thus not needing the bip373 and making quadspark useless (was thinking of using quadspark from diy but then i had read this somewhere)

And the big question is can i mod the board like the quadspark instructions but instead of connecting the quadspark wires just hook up to the toyota cop's trigger. Making 4 trigger wires instead of the two shared ones (4&1 and 2&3)

I just feel like i'm missing a piece of the puzzle or something very easy and fundamental.

Neither the stock Mazda ignition nor the Toyota COPs need a QuadSpark.

Toyota COPs have a built in ignition module, and as such do not use the QuadSpark.
