I just got the flashscan v2, I barely know how to hook it up let alone use it but from what I get I prob need to recalibrate the o2 sensors for the unrestricted flow of exhaust. More or less I have 2 stock exhausts with no cat and a straight through muffler. At certain rpms it quite but then when the fuel gets dumped its obnoxious. You can see the raw fuel coming out at WOT.
Can someone direct me to what to do or maybe just a map to try, or some further information.
I've been reading but its going to take little more playing around to even start to get the hang of this.
Like I said,
04 GMC Crew Cab 1500 z71 5.3l LM7 295hp The best mileage I've seen is 13.5 but average 12 on the highway. I fooled the secondary o2's so there no cel light on, but you can tell its dumping massive amounts of fuel.
