Without the TE2 pin you will not get an obd1 data stream from the 7mge. As far as I know the mx83 cressida was the only 7M ecu with the TE2 connector. Without TE2 the VF output is only basic fuel trim in 1.25 volt steps to 5v I have tried this on my car and managed to get the data stream to work but nobody seems to know what the values convert to. The docs on autoshop101 refer to appendix A for an explanation of the data but the fellow running the site has been unable to supply this information. Maybe if you ask him nicely too, he may go hunting a little harder and we can both get it The data stream is 100 baud and I think 22 bytes long. Ive already written some software to capture and interpret the data but without the conversion tables its pretty useless [Report message to a moderator]
