DIY: Adding new Parameters (sensors) to OBD2 for logging.
I got this working on my Rx8 and figured it could help someone here too. The short story is you can add new OBD2 parameters to the CAN Bus for logging with <$50 in hardware.
Here is the original thread with my kludgy code:

And here is a youtube video I did explaining how it works and showing it running on an ecu simulator:

Let me explain it a little better. With this you can add any 0-5volt sensor (for example measuring underhood temperature) to the CAN Bus so it can be read with standard OBD2 commands just like the stock sensors. You can even do 0-12v sensors or other kinds of sensors with the right coding/hardware.
