The one I ran last night in 17.5 SCT was working great with no hickups. Was very smooth overall and I ended up running some very fast lap times with it. Its a very nice speedo and the Pro Gauge is very nice to program with. Once I was use to it I can go pretty fast on setting up the speedo.
Cool! Once mine comes maybe we ca "compare notes" on settings in the 17.5 SCT class.
