I'm working on a project thats measuring engine performance and fuel
economy. Since the 2005 Ford we're using has a
CAN network, we thought we could get some engine messages off the CAN
connector. We bought a CAN to USB adaptor and started recording
These messages appear common. The software from kvaser, canusb.com,
WGSoft and any other program I've found simply display lines of data
like these (either in decimal like this or hex)
The messages I found for ODB-II are mostly 4 bytes and don't match, and
we've looked at SAE standards and these messages do not match the J1939
documents we found (although they are 8 bytes).
Does anybody know how to convert these numbers into words and real
values with units?
