Thanx for the input, and your link - looks like a good project you have going.
I see you mentioned in your log that OBD is slow?
My car's netowk is running the CANbus protocol, which is is fully OBD-II compliant, and the datarate is 500kbits, so no problem there.
Of course, some older busses like the ISO protocol is a fair bit slower.....
I will keep your advice re damping etc in hand, thanx
