Hi peeps,

I'm in the process of developing a digital dash for the XB models and would need a couple of signals I can't get from the service manual and wiring diagrams.

I need to know if the engine check light connection from ECM gives 12V when active and also
what the TachIn signal (TachOut from ECM) looks like.

Unfortunately I can't check mine anymore as the bike is already in bits after my crash earlier this year.

Hope someone can help

Cheers
Dietmar

Tacho and speedo signals are 5V square waves. Speedo output frequencies are configurable for DDFI-3, or direct connected to the VSS before. The number of VSS pulses is 42 for models < 2006 and 48 for models > 2006, per one turn of the belt sprocket.

CEL is switched to ground for XB, the 1125 instrument cluster uses the CAN bus for his signals (except fuel), IIRC.
