By the same argument, why not also allow the addition of say a crankshaft sensor? Most later cars that came from the factory so equipped are better poised to take advantage of the open ECU rule than say earlier cars with mechanical injection.

NOTE, that I'm not proposing to allow a free for all with ignition and injection systems, merely that all cars are afforded the same advantage that the open ECU rule allows by allowing common stock sensors to be added. So my position is that essentially sensors should be free, so long as the car still runs the stock ignition and fueling systems. And if the guys with carbs can figure out how to run an open ECU for better control, let them!
