Canbus tapping

[mpgscott]

Someone was mentioning that it might be possible to tap into the canbus and then use like a capiride to display engine data such as oil temp and revs and such.

I’m thinking this is only on newer bikes but wanted to ask the community knowledge as to whether we can do this on our K25’s

So anyone shed some light on this please?

Thanks

Depends how good you are at software. I’m sure with a Raspberry Pi or Arduino it could be done, and surely with other microprocessors, you could Bluetooth everything from CAN to your phone too, though you’d need to write a phone app to display it all.

Looks like a load of work, not sure if the benefits would make it worthwhile.

My only question is "Why?"


Back-probing for an Oscilloscope is one thing but interpretation is the key

Where are you going to get the software to interpret the data ??

It’s whether the likes of the various systems out there such as caps ride or chiggee can interpret the data already is the main question? Could these units display the various sensor information on the bike?

a navigator 6 already grabs tyre pressure info and your top speed so plod can help you incriminate yourself

Like I said, you’re going to have to write it.

That's me guilty then.

The can bus data can be picked up from the 4 wires that feed the round socket under the seat .
I have wired an OBD2 connector in parallel with the round 10 pin socket, I use this to feed an Innovate LM2 so that I can record up to 32 data channels as well as the air fuel ratio from 2 wide band lambda sensors.
Socket looks a bit ropey as it is off a scrap car.
Also handy plug the OBDLINK MX+ into.

Wiring for back of OBD2 connector.

don't do it .

do you NEED that information that badly ?

what do you do when you've fucked it up ? can you go backwards to STD ?

could you not get that info via the diagnostic plug ?

I asked if similar could be done via hexezcan and the kombi, the response was the kombi was the limiting factor, it can't display what isn't in the LCD screen


However if the data can be pulled via can, and a suitable display provided, then as said using an Arduino or similar it may be possible

Some of you may recall the early BT gs911, you could datalog about 32 different data channels and with the right software display the data, so theoretically all it needs is a bright spark to do some coding

I can do the coding (I think) but I really don’t want to, and I’m too bloody expensive for someone else to pay
