1 of us has it backwards, lol... probably me. But in my little peanut brain if you are actually covering a mile in 508 rev's and the ECM is counting rev's and looking for 518 revs to make a mile, the ecm thinks you are 10 rev's short of a mile. I don't recall if your original post said how far off your odometer was but doing some hillbilly math I figure your odometer should be about 1/8th of mile short of a mile. Somebody smarter than me needs to jump in here my head is starting to hurt. LOL
