Settings for FC3S tachometer
 

Ive searched and searched, but i guess the information on here is a little hard to find so i decided to ask.

I want to drive my tachometer with the haltech(i cant use the trailing coil packs because they are modified). I know what wire i have to splice into, but what i need to know is the settings to use.

Thanks

4 pulses, 50% duty cycle, 12V pull up.
