CAN mapping for ND Miata (or any recent Mazda)

[arvind]

I recently bought the Racecapture/Track and was trying to set it up on my ND Miata. The OBD worked as expected - but when I tried some CAN message filtering - couldn't get it working (data from : http://www.madox.net/blog/projects/mazda-can-bus/).

I was wondering if that's because I need to be on a physically different CAN bus and/or if my mapping info is incorrect. Would really appreciate is anyone has been able to get CAN working on their Mazda vehicle and is willing to share the experience.
