search for itr rev limiter returned nothing useful
i know that the rev limiter is supposed to be at 8500 rpm on the itr if i remember correctly- cutting fuel. my question is why can u drive it past that point in gear, and rev it past that when not in gear
my friends itr is not stock, but i know it is not chipped. when getting on it pretty hard going from 2nd to 3rd gear, he mis shifted and did not get it into 3rd, just popped out i guess. anyway, the engine reved over 9k rpm's.
if the rev limit is around 8500, and the engine was not shifted into a lower gear to make the engine speed to go any faster, why will it rev past redline at all?
or maybee im just dumb

It is still very possible to over rev any engine.

Re: search for itr rev limiter returned nothing useful (Haleiwa-Brando)
stock tach is not accurate? nvr heard that before explain.
can someone please explain how and why it over revs? i would like to learn something out of this
no fuel, dont think there is any spark, not going in a lower gear, how does the engine turn faster still?

Not exactly accurate. Its usually 300 or 400 rpm off. Rev limiter is at 8400 but mine will show to rev up to 8800 or so. If it is going over that than im not sure.

Re: (01ITR#173DC2ning)
Okay someone explain this better than me... but in a non-technical nutshell...
The engine can still over-rev "mechanically". Meaning if you accidentally shift to a lower gear at high revs the engine (crank, etc) can over-rev. The Fuel cut-off or rev-limiter is just a limiter on the fuel and, I think, the spark. Meaning, no fuel after 8400rpm. But the engine can still spin much higher if you accidentally downshift incorrectly or on accident at high rpm's. Of course if that happens you can blow your engine, bend valves and rods and so on.
Hopefully someone can more eloquently re-state this for you.
And my rpm's were off by about 200rpm's. In fact, my speedo was off by a few mph as well. The stock gauges aren't always accurate.
Hope this helped!

Very true. The fuel cutoff is at 8500RPM though.
However I think the thread starter was referring to over revving in neutral. He said his friend misshifted but did not engage a gear.
I just don't know if you can over rev in neutral or if you hit the fuel cutoff, because I've never tried it.

here's a video of revving in neutral. i'm just making this thread more interesting. someone chime in who remembers this video and tell me what mods are done to the car as it may answer this thread poster's question.

well I remember the video, and whose car it was (sgT's), but I don't know the mods.
Seems to have hit a rev limiter though.

people assume that if you mis-shift that it wont go past redline either...they think they are totally safe having a rev limiter for some reason. but anyways, he probably tricked the ecu thinking it was going to stay in gear, and it went all the way up there. the ITR tach will read about 8700 but in fact redlines at 8400 and some change. doesnt mean it wont go to 10-11x rpm's on a stock ecu.

Re: search for itr rev limiter returned nothing useful (TodaFiend)
yea, i do realize all of that, thanks for the info. i was talkin about it in neutral. it makes perfect since y it would over rev if it was in a lower gear. i guess it just doesnt really matter as long as ur real careful with it

Re: search for itr rev limiter returned nothing useful (KGsITR)
actually fuel cut is 8600 on a stock R redline is 8400
it is even clearly shown on your tach
the red starts at exactly 8600 and that is exactly where your car with bounce off the limiter if your tach is accurate

As an aside, on a road trip to Spokane two years ago I tested out my tach on a long straight stretch of highway, in 4'th gear. My stock tach was deadly acurate for vtec engagement, disengagement, and fuel cut.
But when drivin hard in 2'nd gear the tach would seem to read inaccurately higher.
Maybe the tach carries a bit of momentum when it is forced to spin quickly, and therefore seems to be inaccurate. Just a guess, I have no idea how the mechanics of it work.
