Hi.
I have a TrailTech Vapor computer and i want to know how much PPR (pulses per revolution) must i put with a 120W BGM and SIL flywheel?
I understand that is 1 PPR but if i put 1, i have the double than the real, and if i put 2 RRP is correct.
Thanks for your help!

Mine now looks good with 2 PPR setting.
How much RPM is normal in tickover? 600rpm-700rpm is good?
