i honestly think the market is quite small because you run out of inputs very very fast once you add dbw to the elite 2500 and without an io expander or two you are bordering the limits of inputs for most people. and honestly people will start complaining about costs and additional wiring needed. i think this whole setup is very neat but i just feel personally its a more indepth addition to just getting a dbw controller. those of us who want dbw have already moved on from the 2500 class of ecus and pricepoint and have figured out a way to use dual dbw. however it is not to knock this product at all, i love it and love the ingenuity of it and really hopes more people adopt to the dbw world
