....well sort of. Without saying exactly what the problem is (if any), SW sent me a new tach (same model, just updated they say). During testing, they didn't find anything conclusive with my old tach. However, they are aware there are a significant number of us having similar problems with SW tachs. They maintain SW tachs should be compatible with all electronic ignitions including MSD. At least it's nice to know they will stand behind their product. Has anyone else heard anything from SW?
