Found a little time to tinker this weekend. I built an injector tester. Photos are a bit dark but pretty much the Adruino just switches the injector on and off.

I'm having an trouble with my adjustable fuel pressure regulator, it's a different pressure nearly every time I use it. Anyone suggest a good one? I might just switch to the second-hand non-adjustable OEM Bosch one for now.
