Well, a little late, but I had a chance to install and tune the newest injector style DWUR today. got the AFR's perfect and realized the car wouldn't start. The problem ended up being the engine cranking wasn't moving the throttle plate enough to turn on the fuel pumps. Solution was to richen up the throttle plate adjuster and then lean out the DWUR by increasing control pressure. We are at 14.5:1 at idle and 11.5:1 at 15psi. With all the hot tuning today, we didn't have an opportunity to tune cold start. Once you get the hang of how the software works, it is very easy to use. Not sure what longevity is yet, but we see. Here are a few pictures:
