Hi Tony
I can (pun) make one out of an arduino. Problem you are going to have with any adaptor is being limited to the OBDii speed. If you want just a few parameters out of the OBDii it won't be to bad. But if your looking for a bunch of data you might get into the 1 second or more update times.

Bob, I understand the speed mismatch but this would be going from ODB-II to a CAN bus, so slower to faster should not matter, right ?

Are you looking to get data from a Subaru factory ECU transmitted over CAN? If so, you would want to use SSM, not the regular OBD-II protocol. It is still a relatively slow protocol at 4800 baud, and with 10-15 things monitored you are looking at 8-10 samples per second. I am working on a PCB right now that can collect data from SSM and a few other protocols and send them over CAN (so they can be logged in my RaceCapture Pro) if you are interested.

I am very interested if you can get the data using SSM.
I use a parker plc on my electric vehicles. It has 3 can ports. I can do gauges, bar graphs and much more on the screen. Plus I can add plenty of I/o for additional sensors. Here is a couple of screen shot samples.
