No you missed what I was explaining. There is a page in the MS documentation that shows all possible ways of outputing spark from both versions of boards. I was reading it when i was looking into the LS2 coils i have.

Mine is a direct input into an ignition box. The documentation states the way you do it with a version 2.2 and 3.0 must be different. The version 2.2 you use the NEG of diode 17/19 and run it directly to the ignition box.

On the v3.0 when you do that you get tach spikes. on the version 3.0 you must run the internal ignitors then output the ignitor to the ignition box.



I am asking, since you studied the design of the multilayered 3.0 board, why is that? The components used in the v3.0 vs the components used in the v2.2 are the same values and schematics if I recall. the only difference is the board design.
