I've recently made a calculator to calculate volumetric efficiency based on vehicles with MAF sensors. I'm posting here today to make it available to anyone who would like to use it for free. I originally wrote the program in python and converted it into a web based script. It still needs some work and will be updated.

Here's a current link to the calculator: http://vecalculator.atwebpages.com/
