found an interesting link. i think others have made an interface that works with the odbII system. i am going to be trying this out in the spring. these look like the directions to make the correct cable?

Looks simple enough.

It doesn't work, at least not reliably. The amount of overhead with timing, dropping packets, and conversion make it so it runs extremely low. The 1600 baud rate is simply disgusting, and not of any use for any type of data logging. The ELM interface, that runs at 9600 baud, can only poll about 10 items per second, this pure serial interface which is about 5 times slower, would only be able to poll about 2 items per second.

Buy stuff from CarCustoms Ebay! Won't be disappointed!

yeah, seriously, serial is old stuff.

I thought modbus and controlnet were behind the times. This protocol goes beyond archaic.
