[QUOTE="SecondhandSnake, post: 16467664, member: 116684"] Got a chance to bench test the output side. I checked them with LEDs first, then hooked to the car. Note: you'll need to have everything hooked up to the car power supply, can't have it hooked to the USB for testing. It seems to work pretty well. I was able to sweep through the duty cycle commands and the pump responded. It would just click at 20%, so I might need to bump the lower speed clip to 21% or higher. The time based speed seems to be quicker than it should be. This only really affects the diagnostic output. I'll either need to correct the processor speed, or I can just adjust the values until it's correct. Next up- I'll need to solder up some of the connections to be more permanent and get ready for a "live" test with the car running.
