Need help with G&S LCD Tachometer ZX- 01

[Deleted]

I bought this Tach,volt display and I hooked it up ok ,I just dont know how to set it up . I dont know what the piston type should be set to " 0.5 , 1 , 1.5 , 2 , 2.5 , 3,4,5,6"
Or what the ignition angle setting is changed to " 1 to 2 "
Or what the rpm pulse setting is suppose to be set to

Any advice would be much appreciated for my QMB 139

Don't know your equipment, but a guess is '1' means 1 spark per revolution of the crank. Start there.
