Quick Question About CAN wires

Post by Borgli1 »

Hi guys, I just finished up wiring my MS3-Pro to my V12. I noticed that I didn't use any of the CAN wires. What are they for?
Can't really find a good explanation anywhere.


Thanks!

CAN stands for "controller area network" and is also sometimes referred to as CANbus. It's a networking system commonly used in newer cars.

If you have an otherwise-working setup you don't necessarily need to worry about it. But if you want to, it can be used to send data to things like digital dashboards, or get more I/O for the Megasquirt by connecting an external module. I think it can also be used for communication between the Megasquirt and a transmission controller?

There's some info, perhaps a little outdated, here: http://www.megamanual.com/com/CAN.htm. Also just google "megasquirt can" and you'll see more examples of what can be done with it.

Extra add on devices. Some things on the market right now that can use the CAN wires:

- MicroSquirt transmission control
- MicroSquirt IO Box
- CAN-EGT
