When you floor the gas in Automatic, is it made to reach the RPM red zone or not?

FxJojo,

Thanks for the video. That looks like a pretty standard rev limiter. Mine just revs all the way to 8000 rpm with no limiter in sight.

It didn't appear as if your car "bogs" or "cuts out" at the limiter which is nice. Some limiters like BMW have a cut-out where the engine doesn't actually cut out but bogs down as if you have lost power if you surpass the limiter. For example on the later model E46 M3s BMW started to set a limiter at 5000 rpm that they would remove after the 1000 mile service. It prevented people from destroying their engines revving it past 8500 rpm straight out of the dealership and on test drives. My dealer let me borrow a new M3 once and didn't tell me about the limiter and I took it back thinking there was something wrong with it. It was the slowest M3 in existence, LOL!!

Bottom line is, my FX either doesn't have a limiter OR it has been deactivated. It would be interesting to hear from other 08 FX owners to see if this is standard or not.

You welcome dude. So at what RPM do you shift if you don't have rev limiter? (In racing mode:tongue:)

I'm pretty sure mine hits the red when I floor it. I'll try and take a vid today.

It seems like I'm the only one here that have a rev limiter at 6750, 7000 :tongue:

It should hit the red in tiptronic. The question is how far past redline can you go before you hit a limiter or not.

If you watch FxJojo's vid his limiter kicks in at 7000 rpm. Where as my FX has no limiter and just revs straight to 8000 rpm.

Let us know what you find out.

Here's my vids. The first one is from a stand still showing the shifting in Auto at about 6500. The second shows the rev limit at about 6800-6900

Nice videos Keemo. So you do guys have rev limiter at 6800! but you didn't hit the redline in auto right:confused:? It shifts at 6250.

Well I assume that my 08 FX either doesn't have a limiter or it has been deactivated. I just drove it in 1st gear until it hit 8000 rpm. My curiosity has finally been satisfied...

wow, that would cause serious engine damage.

Nah, it doesn't really concern me. I will never rev it up that high under normal circumstances. There is no need or benefit. I was just curious to see if my FX had a limiter or not, and at what RPM it kicked in if so. I was just looking for an answer.

It would be an issue if there was no downshift override however. But the transmission won't let you over-rev the engine on the downshift. For example, if you are driving along at 60mph in 4th gear, you can't drop it down into 1st even if you try.
