Im finishing up my MS2 V3 build I plan on using EDIS8 Is it better to jumper the JS10 to IGN or to use the High Current Ignition Driver Circuit.
Thank You

MS does not need to drive EDIS8. EDIS is, essentially, a standalone ignition system. You only need to provide PIP from the Ford module to trigger MS. Then MS needs to send SAW back to EDIS to control timing.

Jumpers and wiring are all explained here:

Bottom line....... No driver is required. (high current or otherwise)

Ken Thank you, My board is currently built per the link you included. I started doing some double checking while waiting for my pwm kit and came across this thread which if im reading correctly suggests that it may be better to install the driver circuit

It would work better for me if I dont need it because that will leave a spot on the heat sink (Q16) for my pwm tip. However if that is the better way to go I will.

If you really want to you could install a buffer transistor in the proto area - it only needs to be a medium signal type so no heatsink needed. Leaving the heatsink clear for other uses. But there's no real need if you take care with the wiring loom.
