Hello All,
Anyone out there ever actually tried hacking the Can-Bus between the ECU and the instrument cluster?
I've searched and read lots of threads saying that the clocks and ECU have to be connected and talking to each other before the motor will run. Also, that the speedo gauges don't have to be matched or coded to the ECU, just from the correct model year.
It makes me think that the messaging between ECU and cluster can't be too complex with serial numbers and so on, maybe just a standard response or checksum.
I've done something similar and hacked the clocks on my Suzuki TLR before, but that was just a basic serial interface. Can Bus is a bit more tricky but luckily I have a CanBus development kit to play with (and an electronics degree which is always handy!)
It must be possible because T3 racing have done it with their race dash. We just don't know if they got help from Triumph or had to work it out themselves.
So I plan to have a crack at this and make a little box of tricks that will make the ECU think that the clocks are connected. If anyone else has tried this - let me know.
My other problem - I have a half started race-bike project so I have an engine and ECU, but no clocks to test with. If anyone out there has some old damaged/crashed/bashed clocks lying around that I could strip down for the electronics, that would be handy. No cheap ones on eBay at the mo.
Thanks
