I need to adjust my K-factor. It is currently set at 680. This IO360 engine used 15.0 gallons in 1.76 hobbs hours. The fuel flow computer says it used 18.6 gallons. I would adjust the k-factor as a fraction of 680:
548 new k factor = 15.0/18.6 x 680
The manual says: New Counts per .01 gals = (Old Counts per .01 gals) x (Disp GAL USED/PUMP GALS)
Not sure of the meaning Disp Gal used vs pump gals. Did I calculate it correctly for a new K factor to be 548?
