Hi All,

I'm trying to have a C125 transmit a internally generated state (integer) and Lap Running distance to a haltech ecu. I have struggled to understand the correct settings for the c125 software. Would anyone have done this before?


Since we don't know what your struggles are, you might want to select a CAN Template that transmits messages, and edit that to see how it's done. An example would be "VCS Transmit Compound Full" which sends compound messages, but the details of the individual channels are the same for single messages.

You will probably find the DTN0019 posted in this thread useful:


You aren't able to freely define the CAN signals being used in a Haltech ECU.

All you would be able to do is emulate the signals the ECU is expecting to see from a Haltech peripheral like an IO box.

Something like a driver switch voltage/state or sensor voltage would be easy enough to emulate, but I don't think there would be any way of receving a singal like lap distance.
