[QUOTE="me2, post: 336921, member: 3825"] A couple quick comments. Reading the CAN Bus is pretty easy these days. The hardware to do it is commonplace. Doing something with the data you get off the CAN Bus is another story altogether. OEMs use proprietary PIDs and you have to figure them out in order to get meaningful data. That is where ALL the work lies. OBDII and CAN Bus are 2 entirely different beasts. OBDII is a diagnostic communications system. The hardware layer is defined in J1850 and has a baud rate of 10.4 or 41.6 Kbps. Can Bus is (real time) controller communications system. The hardware layer is designed to run at 250Kbps or 1Mbps. It is possible to run gauge systems with OBDII signals. I think it would be pretty difficult to do engine and transmission control with OBDII signals. But I'm a newbie at all this and learning as I go, so I might be wrong. [/QUOTE]
