Setting RPM on Acewell Dash

[botty]

Need a bit of help. My brain is getting frazzled. I can't decide which default to set, it's so obvious I can't see it.

Acewell dash, zeel pcdi-10v.

Quote from instructions.
It displays "SPC-X.X RPM, the default value is 1.0. There are four options 1.0,2.0,3.0,and 0.5
It means the number of engine rotations per signal. For example 2.0 means the engine rotates 2 turns to output a signal.

Each plug on my bike sparks every 180 degrees, so in affect a wasted spark. So does that mean 2 signals for 1 rotation?

So is the default 0.5? Or something else?
