Ok so the factory rev limiter is at around 8,100. So why is it that you can rev past the limiter if u miss a shift or down shift to the wrong gear? It doesn't make sense....

the rev limiter just kills the ignition for a sec so the motor doesnt keep reving it doesnt apply a 'brake' to the engine, so if you put ur car in the wrong gear it deff will rev past it

Yes it actually does make sense.

The rev-limiter prevents you from over-rev when you are on the throttle. That's built into the ECU to cut power at 8300RPM (this is where the rev-limiter actually is)

However, if you miss a gear (shift from 5th to 2nd for example), that is a mechanical over-rev. The wheels are attached to the transmission that is attached to the engine. The wheels are on the pavement. It is sudden and devastating, and since you are not pressing the gas, the ECU cannot protect you.

Basically, in summary, the rev-limiter is a computer feature. The computer has nothing to do with your inability to shift properly and cannot protect you.

Its because the rev limiter controls the throttle (kind of), not the laws of physics. Your car can only do so much to try and save itself.
