    Ok Guys -

    I connected the MTS to the EFILive Serial Cable by cutting the ends off and soldering the 3 wires together on each.

    I've tried adding the PIDS in V8 to see if the BBx would see the LM2 but it states no sensor found. I loaded the BBx to the Wideband Settings in Scan and tune and still nothing.

    What am I missing here.. I'm at a loss....


    Thanks,

    John

    Did you cross the Rx and Tx signals...?


    On your V2 you can navigate down to the wideband display to see if it is working.

    joecar,

    Can you expand on the signals? Im not following - Apologies.

    I went to the "Show Wide band" and when I select that I says not found. I hit Ok to toggle through 1 & 2 and still nothing. This is on the V2 BBx


    Sorry~

    To talk to your PC, the Rx and Tx wires go straight (not crossed).

    To talk to V2, the Rx and Tx wires need to cross (i.e. null modem cable).

    Thats probably my issue.


    Here is what I did.

    I took the MTS to 3.5MM cable from Innovate and cut the 3.5mm off - This left me with a Red, White and Black wire.

    I took the Serial cable to RS232 (EFILive Cable) and cut the Serial end off leaving me a Red, White and Black wire.

    I thought by connecting these two cables together I would have in essence a direct serial cable from the LM-2 to the Flash Scan V2.

    I don't know that the red/white/black on each cable correspond to each other...

    does the LM-2 user manual indicate what each of those 3 wires is...?

    I just looked at TAQuickness's instructions for the LM-2 cable, they say to connect SERIAL OUT to FlashScan V2...

    i.e. SERIAL IN will not work.

    I think that you should explain to Innovate that previously the SERIAL OUT was used to communicate with the EFILive FlashScan V2, and that you need an LM-2 that has the SERIAL OUT port.

    The LM-2 has a MTS 4 pin "In" and a 4 pin "out" on the side of the case...

    As per the manual :

    Serial Out
    Pin Use
    1 RX
    2 TX
    3 GND
    4 GND


    Can this still work?? I'm not sure of the corresponding color wires as I don't have the MTS wire with me, but can you tell me what the colors of the EFILive Cable correspond to with regard to TX, RX and Ground?





    Any help is appreciated,

    Best -

    So it has a port labelled MTS SERIAL OUT...?

    If so, then that is the port you want to use;


    you want a "null modem" cable (meaning Rx and Tx are crossed, see post #14 above, those links show the EFILive cable wire colors).

    Joecar - Thanks for all your help. Here is what is needed and how to do this without a null modem adapter..

    You will need a Innovate #3812 Serial Patch cable that has a 2.5mm jack on the other end and the Flash Scan V2 Serial Cable.

    The #3812 can be had on Amazon for $12.00 if you don't have one in your LM-2 kit



    Take the #3812 and cut the 2.5mm Jack off the end.
    Take the V2 Serial Cable and cut the 9 pin female off of that cable.

    You will have a black, red and white wires in both cables after you prep them.

    Solder Black to Black
    Solder White to Red on the respective cables.

    This as you stated provides you with a Null Modem Cable Tx and RX crossed in a streamlined cable.


    Thanks for everyone's help.


    Best,

    John~
