My Acewell 7659 dash is reading half revs, connected to Kawasaki z1000 ecu output.
Has anyone got any suggestions on how to get this to read correctly ??

You need to change the setting for rpm pulses, if you currently have it on 1 I think you'll need 0.5

Hi, I can get to the r1p1 etc selection but where is the rpm value ??

Sorry, my bad, I was thinking of the earlier Acewells with which I'm more familiar, The 7XXX series does it differently 1r1p = 1 revolution 1 pulse, & so on, so if you are only reading half revs you are getting half the pulses you need, so if set on 1r1p I think you need to change to 2r 1p

HTH

OK, Thanks I'll give it a try
