You sure it’s the rev limiter? What gear were you in?
Rev Limit Cuts Engine at 120 mph
I was on a road trip in my RS thru desert land. I opened-it-up a few times, and each time the rev limiter cut in at 120 mph. Elevation was about 4,000 ft. I expected to be able to go faster than 120 mph!
Any thoughts?

Ok, if you were in 6th gear and the actual rev limiter stopped you from accelerating past 120mph, the clutch is slipping, the tire/wheel diameter is much smaller than stock, or the final drive ratio is not stock.I was in 6th gear. As I watched digital speedo I saw the rpms qaapproach redline and the engine c
Vehicle is 100% stock.
Well if you’re at the rev limiter (ie 6500rpm) in top gear and only seeing 120mph, then the speedometer or speed sensor is “bad”, or the clutch is slipping. The MyKey setting has nothing to do with the rpm limiter, just the road speed.the vehicle is 100% stock. .. as far as the clutch slipping >>> no indication of such.
Edit: Hmmm? The above fault items are actually less likely than you’re not really in 6th gear, but in 4th… 1st thru 4th have a shorter final drive gear set than 5th & 6th that have a taller final drive gear set.
The real problem could also be you’re just a troll!
You are obviously a trolling idiot. Go away.How pathetic ..
Uhm, the OP is an idiot. Reminds me of the stupid f*cks on the honduh forums during The Forum Wars back a decade ago. Well, before I was banned. The title of this thread says “rev limiter” at 120 mph” not some ambiguous rpm, the rev limiter, which is a simple thing to discern. Close the thread and move on.
Jesus man, there is only ONE rev limiter on any modern vehicle. There is a top speed limiter on many as well. Two completely different functions. The speed limiter does NOT control revs, it controls throttle to maintain speed. That why the speed limiter is always a soft occurrence.
If you read my posts, I asked such questions and the OP is an idiot.

The “speed limiter” only affects revs in that when the throttle is modulated by the speed limiter, the revs follow the speed. It’s a manual transmission after all. The “rev limiter” functions with completely different input and output parameters. If you do your own tuning as I do, you should be able to see the functions performing in a data log.Ah, to me they are two different methods of limiting revs/speed. The speed limiter does control revs, otherwise it could not control speed. I've had the rev limit feel smooth too after using the over rev zone too long and it was slowing me down to the lower limit before a braking zone.
The function is active, yes. A stock vehicle will not see a problem at sea level or at 4000 ft. At very high elevation 9-10k(?) you will see/feel a loss of power as the turbo(s) may approach the over speed ratio set in the tune.the air at 4000ft is thinner than sea level, your ecu will pull boost and timing to keep the engine within its operating range.
does it do this even at sea level?
Yes, I think I asked this way earlier because it did and is the most likely cause at this point. If the guy is indeed 70+, he likely won’t respond because he feels like the idiot he is…Or it was actually 4th gear…. Cuz the math checks out
