Free Volumetric Efficiency calculator

Used this a while back and it's pretty slick (nice way to see how the MAF is working, even though Duramteric provides flow rate & voltage for some DMEs). It has four fields to input data (engine size, RPM, MAF, IAT) but the parameters are not metric so you'll have to change the engine size from liters to cu in, MAF from kg/s to gm/s (DME only provides kg/hr), and intake air temp from deg C to deg F. I typically get the parameters from my Durametric tool, convert them, and then plug them into the program. The program is provided as a Windows executable (sorry Mac people). Enjoy!
