cheers for the replies guys, sp0oke to the Aussy importer of Mychron & he adv any cyclinder & told me where to change the settings so i'll see what cylinder lead works

I got a koso db02r and the rpm only works for the nc30 attached to the live wire to the rear coil blue/yellow one... I then set the unit to 2cylinders one piston and rpm is pretty much exact..

Could i ask what steering damper do you have fitted to your build mate... and does it work properly or bang your knee when turning as I have been led to believe that only a sprint damper with total travel of 140mm will fit the nc30 and it has to be mounted backwards.. Only they dont make them anymore so would appreciate the help with finding one that does as my bike trys to slap like a bitch on corner exit at speed...

sorry for the thread jack.... cheers Anthony
