Hello, mates

Here I am again with a problem with the bep 3.0 and the acewell MA085.
Now the problem is that when I'm over 5000 rpms the needle start jumping. Under 5000 it works fine.

Any ideas? I just plugged the wire to the RPM hole in the bep.

Thanks in advance.

I can't speak for the MA085 but with the Acewell 2853 model, the RPM worked perfectly when the Black/Blue wire (from OEM Coil INTO the BEP3) was connected DIRECTLY to the RPM input of the Acewell (i.e. NOT going through the RPM conditioning circuit, but connected directly)
Try it and see how that works
