Title says it all

KFMIOP shares same load axis with:
KFZWOP
KFZWOP2
KFMDS

So how to properly scale KFMDS to new axis? Should I just increase the values by same percentage that load is different from original?

Original KFMDS at 480RPM and original load 100 was 3.3511. What would be KFMDS at the same RPM point but rescaled load (load 159; 480RPM)?

So what I'm thinking is this:

The're is 59% increase in load so the engine drag should also be increased by 59%. Am I right or wrong on this?

TIA

I already have answer for this old question Basically you would have to create some sort of interpolator
