Calculated RPM function

Post by Doig5710 » Sun Aug 06, 2017 7:55 am

Hey just wondering if there was a function in the picoscope tools to create a calculated RPM function off of a given input to help detect low output from a specific cylinder or help find the cause of surges? Something like this would be good, i might just be a bit blind and be going past the function, but i have had plenty of uses for it and dont want to have to buy a different brand of scope to get it as i love my picoscope.

Yes it can be calculated from the crank sensor signal.
I see from your capture that you use a Pie in the Sky / TiePie Scope.

What if it has a non equal crank sensor spacing or multiple missing tooth type setup though?
No i dont own one they are sold over here in NZ and the sales company puts in lots of problem solving articles which are quite handy but it was this feature i hadnt worked out on the pico yet.
