set technically? Is the "blazt" cable and the interface on it that pertains to that diagram considered to be part of the ECU? I think its what gives it a clockrate (and defines the baud rate) and allows a terminal to be connected. Not sure it really matters but this must mean that the R-VIT has a similar design but for whatever reason it doesn't like some ECUs. My hope is that i can spoof it somehow to connect to my PC serial port and pass the data from the USB consult cable along.
