1) Is the time based controller any good? I'll be using it on a DP system for my H22 Prelude
2) Does anyone have a wiring diagram and instructions for it? I've been offered one for good money, but it doesn't come with any wiring or any instructions.
you're talking about a progressive controller. a time based controller goes 100% after a given time. a progressive lets the nitrous build over a given time span.
