Re: OBDII Mt conversion???

Do you know for a fact that this is a bi-directional line that operates as you say it does? Like I said earlier, the ECU pinout calls this line an "input" which implies it is one way. And the signal looks like it has a base frequency of 100Hz. That seems too low for a typical bi-directional data line. I was thinking it is more of a sequence like "data is coming", "start bit", "data", "stop bit". It could be even simpler. I have seen data links where a low speed signal is used to establish a connection and then it switches to higher baud rates. But that is not what this appears to be.
