The 730 has 159(9F) for the speed density calc(cylinder volume). But the 730v.3 uses the same hex(9F) but has a value of .18 liters in decimal format. I know how the 159 is derived from the anht hac, but what is the formula or conversion to obtain .18 from a 9F hex. Any input would be greatly appreciated.

 

Finally figured out the value is inverted and rounded. Sometimes this ecm makes me feel like such an idiot!
