    Default Logging 2 LC2s in series.

    I have made a serial cable that works well for the LC2. No problem, except I have one in each bank. I noticed that the LC2 out and the LC2 in connectors are the same.
    Should I connect the OUT of one LC2 to the IN of the other by making my own molex adaptor or is there another ? I would prefer stay serial cable vs using the AD inputs for this.

    Ok, I have 2 - LC2s. I connected OUT1 to IN2. OUT2 -> Serial connector on top of V2. I only see one wideband on the log. I have both Serial1 and 2 selected in the PIDSs. On the V2 handheld, only 1 is recognized also(display setup for 2). Ideas?.

    edit: they both work via analog

    You have to log in to logworks to set which is master and which is slave. In the end it will be out 2-> in 1-> v2

    I checked LM Programmer and Logworks and there is no mention option I can see that has MASTER or SLAVE settings. Please specify how I get to this option. I just download the Logworks from their site.

    Here is how to make it daisy chain and show up in EFI's Log and on the V2. (I never found a SLAVE/MASTER setting as indicated above so I guess it isn't needed; user above can explain this procedure)
    Yep, all you really do is connect the two.

    If using two LC2s:

    1. Make a Molex connector that will join the IN and OUTs.

    2. Connect OUT2 -> IN1 and OUT1 -> V2 SERIAL PORT; Note that IN2 is not used and it DOES NOT have to be terminated like the LC1.

    3. Go to the Ver 7 EFI Scan tool, PID Tab, System Drop Down Box, WO2-Serial. Select EXT.WO2AF1 and EXT.WO2AFR2

    Test time in am...
