Crank sensor voltage?

I checked the AC voltage coming from my crank sensor (it is a CPS reluctor pickup from a Honda S2000)

It reads from 12/13 volts at an idle (900 rpms) to 25 volts at 6000 rpms.

What values should I put in the trigger arming threshold table? 7 seems to be the highest it will allow.

Would it be benificial to use a different pickup?

The arming voltages should be about half the peak voltage. In thins case the signal is nice and strong so you can run high arming voltages I would suggest start at 1V and work up to about 5V

In theory if the trigger signals had no noise on them you could run a 0.2 arming voltage all the way.
