Even though a circuit like i mentioned would be interesting to try if the VSS behaves like previously posted, it would be much easier just to upgrade to stanalone or chipped ecu. I've just bought a hondata system and it removes the speed limitor and can raise the max rpm if desired. This is because the car is being built for a full race setup. Like Mr.Fat said, in most cases it's not worth the trouble to remove the speed limitations that govern your car- especially if you haven't done many mods or aren't very hardcore.
