CAN bus with hydra nemesis 2.7 ems

I have a hydra nemesis 2.7 ems with CAN bus. I have the hydra CAN bus protocol, http://www.mrcontrols.com/downloads/hydracan.txt .

Will I be able to run a arduino uno with a shield and get the information I want from this ems?

I would like to use this library but not dead set on it.

End game is a 5-7inch lcd screen with all the information from my ems that I personally want displayed

thing is, I cant find anything on the hydra with the arduino.

so can we edit an existing can bus library to retrieve information from the hydra?

This probably indicates its not been done before.

So really, you are on your own, and will probably need to take your best guess about what hardware you will need, and then buy it and try writing software to use it.
