Waiting for videos to upload from testing today - Good success today...
I did get a "pressure curve" from the muffler tap today and its quite exponential as Bert expressed - Here is the quick graph of it..
I stated yesterday that muffler pressure seemed low but the numbers today were better - I put a 4 oz tank in line to add a buffer and got better numbers on the manometer - I think it does a bit of a sampling average and the pulsating when hook directly must have effected it. It showed about .9 psi at WOT so one of the test I ran I closed in the bleed to mimic that pressure and it ran well at this setting.

I think you might think the pump is bigger than it is Bert - Its quite small... controller would be the same size and still runs of the receiver power with very little draw. The pump weighs 5 grams more than the solenoid and we don't need a crap trap. The needle will be a simple "restrictor" in the vent line tee when we know what size it must be. Overall I think the volume and weight will be less. It's a less precise system based on early test but seems less critical in setup also.
Will post video when processed...
