Does anybody know what Load is calculated by?

As far as I can tell the 3 primary inputs the SGII is Load, RPM, MAP.

Note: only the data of the request and only the result of the response are show.
yy 00 -> xx xx xx xx   bitmask of capabilities for mode yy, bit7 represents pid 1, bit6 pid 2, etc, if 
data4:bit0 is set then pid 20 contains capabilities for pid 21-40

01 00 -> xx xx xx xx capabilites 
01 01 -> [b7: MIL light, b0-6: dtc count] [b4-7: readiness] [b5: o2monitoring] [b0-7: readiness]
01 03 -> xx xx  Fuel System Status		bitmap 	b0:Open, b1:Closed, b2:Open-Driving, b3:Open-Fault, b4:Closed-Fault
01 04 -> xx     Calculated Load Value		%	x*100.0/255
