@baronrojo 

I have always wanted to read the TPS & RPM data of DUCATI and YAMAHA through CAN. Can you please tell me?

Cheers

It may seem incredible but I'm always overloaded with work and this has been delayed once and again! I'm starting the conversion right now. For the time being I have removed the old EX+ dynojet electronics as well as the Theta controller (I'll be using the YourDyno controller instead).

I have designed a two piece phonic wheel that will be laser cut in two parts and bolted to the existing one tooth dynojet phonic wheel.

I have also fitted the YourDyno DAQ and power supply as well as the zeitronix lambda controllers in the EX+ electronics cabinet to have a neat arrangement. I have also taken the wiring from the Dynojet AFR pump to the cabinet to reach the controllers.

I'm planning to add some external connections for 'analogic' datalogging from my Zeitronix ZT-2 lambda controller and data logger as it has been extremely useful in earlier tunes.

I've been experimenting with a CAN sniffer on some bikes and it seems that I'm now capable of getting data fro, RPM and TPS straight from the bikes so, I'm really pleased with the optional CAN capabilities of the YourDyno DAQ.

I'll be posting separate questions in the forum on particular subjects so they can be useful for anyone.

 

Cheers!

 

Any updates on your project?

I did end up with a dynojet 250i and everything is still working on the EX stack and the WinPep 7 software but I went ahead and purchased the YourDyno V5 Package a few minutes ago so I will be upgrading.

Initially I plan to use a Rotary Changeover switch to the retarder so that I can run the YourDyno package and the Winpep 7 simultaneously and be able to select which system will have control over the retarded. Both systems will have independent RPM inputs from the  roller. It should be interesting!!
