Cool but what i mean is that your ODO with 175 tires is inaccurate in first place as yours and mine for that matter bigger 175 tires roll slower then 165 tires as they roll faster. What that does is on 175 your ODO is short by x2.5% of total mileage on miles. So if your ODO shows 426 miles it's NOT 426 but really 436.65 so then you divide by total gallons burned. If not adjusted/accounted your manual calculation will be off. So i guess what i'm trying to say that your figure might be correct if you are NOT adjusting manual mileage to tweak guino. If you had stock tires you would not need to do this. Hope we can collectively figure this out here
))) You're getting pretty good MPGs bro. What psi on tires you running. Andrzej if you can help us figure this out it would be great. I just started this so right now your calculations are overwhelming me a bit. Maybe in time i will re-read and reapply. I'm hoping we can get correct settings for the this device.
