Got my recal'd MAF back from Pro-M, a few questions about the flow sheet???
So I got my 75mm Pro-M chrome bullet back from calibration today and i'm completely lost when I'm trying to understand anything on the flow sheet. Maybe someone can help me interpret it:
Flo Pt.
Set Point Kg/Hr
Stand Kg/Hr
Act. Volts
MAF counts
Lbs/min
% Err Er/Abs
% Noise
Sonice nozzles selected
I wish I could scan it, but it's hard when you don't have a scanner...

Well since i'm all jacked up on coffee right now and have nothing better to do I'll put in some inputs.

looks like at 'y' cfm you have a coresponding 'x' value.
I can guess what the x values are, just a guess.
Set pt kg/hr =kilograms per hour (metric version of cfm)
Hr-Stand kg = Avg flow for per hour
Hr-Act. Volts - Maf counts-lbs= Actual hourly voltage pulse
Min-%Err Er = Error count per min (% of total reading, of the actual voltage pulse)
Abs-%Noise = background noise (% of total reading, noise being vibration in the car
causing movement on the maf sensor)
