Hi everyone,I'm building a two stroke test engine.
On the bench I have the speeduino nicely working..
My question is,can I use 2 cop's on 1 coil driver port?
Because my cilinderhead has 2 spark plugs..
Later I will upload some pictures for who's interested.

Regards all.

Yes. To do this, bypass or jump the channel's 160-ohm output resistor. You could remove it and replace with a wire if you prefer. Use two 15-ohm resistors from the channel output, one to each smart coil. Yes, fifteen ohm.

The single 160 is too much even for many single coils, so it is not used, but a small resistor per-coil is used to prevent ringing or harmonics between the two coil inputs. 1/4W is fine.
