Sniper learned a new trick.
8 hours into a drive from Indy to Fairfax my fuel flow went from 25-30 at 80mph to no these that 50 with idle being 9-11 which is double the 4-5 it normally is. Needless to say the car ran like crap! No visual issues with anything and my o2 was reading normal. So, I flashed my last tune in, from before the auto learn on the trip, and it's fine. What happened? I would like for this to not happen again but I have no idea where to start.
