The power commander fuel control (pcfc) system allows customers a low cost alternative to the power commander v (pcv).All of the same fuel maps that are available from starting line products for the pcv can be used in the pcfc as well.The pcfc cannot be outfitted with optional accessories such as autotune, wideband 2 and the lcd display and the pcfc does not have ignition timing control capabilities like some of the pcv models.Lower cost and simplicity are benefits of the pcfc.The pcfc does have end user custom fuel mapping capabilities similar to the pcv by plugging into your laptop or pc with the included computer link cable
