    forgot this thread was here. anyone know what the vss source '44' is in fg tunes?
    also, if the speedo cal is the same, to change vss source, do you still need to disable VID block or can you just change vss source?

    also i posted this in another thread, the ba abs sends speed data to the pcm in a 5v square wave signal just like the speed sensor would. the VSOUT signal (used for sat nav etc) is a 12v square wave signal.
