Therefore my correction factor should be 1 - [(9.7-11.7)/11.7] = 1.17

Done in US friendly units:
1 liters = 0.264172052 US gallons
Therefore: 11.70L = 3 US Gallons / 62.5 miles
Comes to 20.8mpg average (aggressive driving + ac always on)
Having a correction factor of 1.17 would increase your gas mileage wouldn't it? That wouldn't make sense unless your car is more efficient now with the TS.

Well that confuses things a little bit. hoverguy says calculation is done in the instrument cluster and not the OBC. However, the OBC is inside the instrument cluster. So how does the data get to the driver? OBC->Instrument Cluster->Driver?
