If your doing MAF scaling use the VGI utlilty as it imports your OL fuel table from Romraider so you don't need to log Commanded AFR just measured AFR
and the utility does the rest

This is what's in my logcfg:

paramname = AFR_Commanded
paramid = 0xFFF8A974
isfloat = 1
So it doesn't appear that the scaling is set on mine, however it doesn't seem like the formula in the one you posted is correct either. Based on my logs the formula should be:
Commanded AFR = 14.7 - (14.7 * x)

in RPN I think that would be this:

Commanded AFR = 14.7,14.7,x,*,-

I'm not sure if this is the correct notation for this formula or not.

Also, I came up with this for throttle plate percentage. I think it's correct.
