timbo Posted September 4, 2014 Share Posted September 4, 2014 Does anyone know the details of the pulse signal type for the GEN 2 1340 hayabusa. I am using the stock hayabusa ECU. The tacho out signal is Pin out 38 - had planned to use this. I am having the std Caterham Tacho modified to suit the busa install and just the electrics side of the guage to sort now. I have searched the pdf manual but no details on the tacho signal are apparent. Link to comment Share on other sites More sharing options...
elie boone Posted September 4, 2014 Share Posted September 4, 2014 Sorry but it's not 100% clear what you need to know, if my memory is correct then on a X-flow the signal to the tacho is white/black Link to comment Share on other sites More sharing options...
timbo Posted September 4, 2014 Author Share Posted September 4, 2014 Eile, its not a wire identification issue. I know the exact details of wiring schematics. It the pusle signal generated.. eg 0.5 pulse per rev, 4 cyl wasted spark, signal coil per cyl. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 4, 2014 Member Share Posted September 4, 2014 Have you got any description of the ECU? Model number or make and serial number? If you can't get an answer could you do this experimentally? Connect them up as is and calculate the error factor? Possibly measure the engine speed with a stroboscope?
