ooooooooo looks a lot more technical and complicated than the average flow bench
trying to figure out what all the boxes are for?? top one is the original flow bench controller? middle one I would say scope by the coax leads going in, but there is no display so I give up. bottom one is variable voltage power supply?
top one is a fluke 5 1/2 digit multimeter, middle one is a HP Frequency Generator, bottom one is a manson variable power supply.
I have another HP Freq Gen just not setup atm so i can feed both MAF and VSS in. Jimstim in front of the PSU and i have another cheap freq gen next to jimstim to feed in knock signal and another board to convert crank for cam pulse.
test run, holds pressure ok with a set of 42lb injectors, biggest i have atm. B10 is the fuel pressure. Will need to try higher pressure and see how it goes.
