    I had a similar issue with my logging(just single plx but same issue). Power up the plx for about 15seconds, then connect maptuner and finally start ski. Seems the power up sequence is critical, or atleast it was in my case.

    yes , if i use only one PLX then it will show AFR on display!!!

    but when i do the daisy chain method as per the instructions, then i wont see any AFR on display.

    i didn’t post the picture when the 4 plx’s device were connected to the battery, i only have this pic for a reference.

    i did connect all of 4 plx’s devices to the battery, still no AFR’s reading showing on display

    heck i tried each plx device separately, they work separately perfectly, but when doing the daisy chain method, AFR not showing on display

    i did remove the termination jumper from 3 boxes, and kept the first one installed , then the last box in the daisy chain will connect to the maptuner x display, as per instructions, still no AFR display
