Okay, I've not fooled with my programming for a while. I took the truck in for the fuel filter recall yesterday (last day) and got the tailgate cables done too so they'll quit sending me the postcards. I broke out the laptop and cal flashed my "baseline" 2002 OS. After getting home, I reflashed with an 80 hp tow tune that I had on file and was meaning to try. I did oil & filter at the same time, so I thought I would stop the "Change Engine Oil" warning. Appears to reset using the "throttle dance" but comes on with every startup. I hooked up scantool and used the "oil drop" (first time I set it to 0% - DOH!) but I've set it to 100% twice now and still get the "Change Oil" What gives? I just checked and I'm using the latest version and builds.
