I just dug this old post up while doing a search.

I think I can confirm that the rev limiting rotor does need to be timed different than the US spec rotor. When I bought my car many years ago, it had a us spec rotor installed from the previous owner. I didn't know I needed a rev limiting one until I planted my foot to the floor and missed a shift. To my surprise, the tach spun well above the 6800 limit. After much research I purchased and installed the correct rev limiting rotor. Ever since, I have noticed that my timing was advanced a few degrees too much. I suspected the rotor, but never made the connection. I have yet to adjust the timing to the correct specs, but need to get around to it, as I have a bucking under load when the engine is very hot. Does this confirm that the rev limiting rotor is clocked slightly different than the US spec?

Just thought I'd put in my $0.02.
