I put 20k miles in my fuel log, assuming my OEM tires and odometer were accurate. Then I bought taller tires. In the course of testing them, I calibrated them during a long drive to Southern CA. The odometer readings with the new tires were 9.9% pessimistic. 100 miles on the odometer was actually 109.9 miles traveled. I checked this over 20, 60, and 80 mile distances.

When I got back from that trip, I checked my OEM tires, and found the odometer was also pessimistic with them: 100 miles on the odometer was 103 miles traveled. Yes, I went back and redid my mileage log(s).

Both UG & SG lose miles during the key off/ECU reboot entering EOC. If I drive my 10 mile test loop with cruise control, and then do the same drive with EOC P&G, I'll see a .3 to .4 mile shorter trip distance with UG or SG doing EOC with the key. If I do it with a kill button, the trip distance is the same as with cruise control.
