I just want to remind everyone that testing is in two stages; functional and loaded. This is a large concern for many of the designs we see posted here, and Nick properly and thoroughly tests his, but it takes time. This test stage is only simulated function, with LEDs, oscilloscopes and dead loads like resistors. The real-world testing (that unfortunately some here leave to users) is load testing under realistic conditions that include dynamic loads of real inductors (injectors, coils, solenoids, etc) that have very different dynamics. These differences include stuff like EMI, reactance and flyback voltage, which can (and do) completely change how the design handles it, often quickly showing weaknesses in real-world application. We are all excited for Nick's development, but give him time to do the full testing, so you don't have to worry you're design-testing on your engine.

Thanks for doing it right, Nick.
