RE: Fuel mileage - Chamberpains - 10-17-2019
You need to know how many revolutions per mile your tire makes. Look up your tire manufacturer, model and size or call a tire shop (they should be able to tell you) That is the number you need to enter in the ECM. There are settings in the ECM to adjust for tire wear. But I don't think they work all that great so I disabled mine.
