#135295, "RE: Coil on Plug Help!?" In response to In response to 4
Originally posted by Gruff511 Ok well i just got a ms3x board and im trying to use the 5v logic level signals it provides, would i just use 2 ignition wires from the ms3x board to run wasted spark on them? And would it be better to get a coil with a built-in ignitor or it doesn't matter?
You could use spark outputs A and B with a 4G63 ignitor and your stock coil. If you're set on using COP coils, you can wire them to spark outputs A, B, C, and D. If the ECU has a camshaft position sensor signal it can do true COP. Otherwise you will have to use "wasted COP" mode, which controls the coils individually but in a wasted spark fashion.
If you're using the MS3X's 5V logic level spark outputs, you have to use coils with integrated ignitors, unless you're using some sort of buffer in between the MS3X and coils (e.g. 4G63 ignitor, CDI, etc.).
