load is how hard the engine is working and since we are dealing with fuel injected cars its going to come from a percentage of how much air is being taken in/ how much air can be taken in.So how do some dataloggers calculate load?
its a percentage of how much air can be taken in divided by the maximum amount of air your car(setup) CAN take in.
If you are dealing with the stock MAS and it reads in Hz however many hz divided by the maximum reading your sensor can take in.
FYI, its easy to peg the stock MAS hz reading which is also why the stock boost guage jumps to 14 psi (max load), with very little effort. I guess you can use it as a reference point in that aspect (percentage).
Max Hz reading with your given setup at ____ psi peak is 2500 Hz.
If you are measuring 2000 Hz in a 3rd gear pull up a slight incline. Your load is 2000/2500 x 100 = 80 % load .
Why is this number so important to you anyways?
Once upon a time when I was watching topgear and the Veyron's hp guage, I thought to myself it wouldn't be hard to dyno your car, find out the maximum hp your setup makes and change the stock boost guage to read hp (well sort of).
IDK I thought it would be cool.
