    Question regarding ford firing order

    While performing a cylinder contribution test on a Ford 5.4 using the Modis Ultra, is the miss firing cylinder on the screen the cylinder in the firing order, or as located on the block?
    Found the info, the cylinder that shows weak is the cylinder as viewed in the block layout, not in the firing order.
    Thanks anyway.
