    does this mean that we cant log OBD2 while the serial cable for AFRs is plugged in. Only thing we can see is AFR's, is there a way of being able to plug in both the OBD cable and the serial cable to be able to read the AFR's allot more accurate and also log the cars activities?

    The wide band serial cable connects to the RJ12 (6 pin) connector next to the USB connector at the top of FlashScan.
    The OBDII cable connects to the RJ45 (8 pin) connector at the base of FlashScan.

    So yes you can (and must) log wide band O2 data simultaneously with OBDII data.

    So this is what I need? (The Link is old from OP)

    MAX232 RS232 to TTL Converter Board.

    I can't find my serial/RJ12 cable from EFILive. I was going to have one made locally if practical or order a new one. Can someone give me specs on how a cable should be configured to work between the DB9 and Flashscan V2?

    Thanks in advance.

    I found my serial cable from EFILive and must say it is of good quality.

    The only thing I noticed was that I required a gender bender because the DB9 plug on the RS232 converter was male and so was the plug end on the EFIlive serial cable.

    You can make a cable but the EFiLive cable is to sweet.

    Look back through the threads and find the picture of the RJ12 plug and the phone jack, that will explain the RJ12 end.

    This was a pic I dug up on the RS232 Converter that I purchased, so it should give you a better idea on the DB9 end.

    Cheers

    Thanks. Blacky ended up saving me the trouble of building my own. He must be aware of my limitations.

    A gender bender wont work with the way they we modified the PLX.

    That TTL converter board is a female but when you put the gender bender on to the V2 cable it wont work because the entire plug is the same wiring as the V2 cable. I havent tried a null modem cable yet coz i dont have laying around (but it should work). I just made a cable up exactly like Mick did.

    RJ12 plug
    flat cable
    DB9 Male plug and used the shell that came with the TTL Converter.

    I couldnt find any converter boards that had a male on them and if you soldered one you, you have to cut tracks and re-route them.

    For those that want to try replacing the female socket on the RS-232 converter with a male, this is what you should end up with....
