Anyway to disable it. I've found myself hitting it more & more during aggressive driving. Like when merging in traffic in 1st & 2nd gear. Can't always look at the tach & the road & the cars that want to hit me & the cars that won't let me merge & the slow moving cars in front of me. Gets confusing The 6 speed with headers & such feels like it wants to be pushed more in the RPM band then just cuts off. Maybe raise it if not disable it.

Yeah that's a fact!! Would probably need a new ECU to do it. I had a Dinan chip in my Prelude and it raised the limit from 6700 to 7500. It would rev to 7200 like nothing with a 2.3 4cyl. Feels like the CL could definitely do a few more RPMs in 1st and second. BMW used to have higher rev limits on the lower gears of their manual cars as you are not holding the car in the upper rev range for very long.

I hit the rev limiter this past weekend for the first time. I was passing 4 cars (on a 40 mph road). I was jamming to some music and forgot to shift (in 2nd gear). It scared the shit out of me when it jerked on me. Then i paniced and dropped it into 5th.

I hope the people I was passing didn't get a good look at my expression when it happened

I hear that. I was doing 75 on the highway and dropped it into third. Before I knew it, I bounced the tach. It jerked so hard I almost hit the steering wheel. Good thing I had on my seat belt.

Get a TSX and do 75 in second in the auto... that was funny watching it go up to that while merging onto the highway in SS. I forget what the 04 TL did, but probably similar with less time to get there.

Rev Limiter is there so your engine won't go BOOM!!!

I nominate this for "Dumb Topic of the Week"

darrinb

its there to protect ya, i can actually tell by the sound of the engine when its time to shift

J.T.'s 3.2CL

Would that cause an over-rev code to be stored in the ecu? If not how high would you have to rev it? Anybody?

Yeah Yeah Yeah Yeah Bla Bla Bla....

I know, but still the car wants more why not give it. At least being able to raise it would be great.

Will the unichip thing if it ever comes out for 6 speeds be able to do that?

J.T.'s 3.2TL
No this will not through a Over Rev code. You need to shift past the limiter & red line. Like downshifting into 2nd at 100 or 1st at 80 etc.

Besides possible damage to the engine, valve float might become an issue as well past 7k.

I used to bounce off the limiter alot when I first got the car, but I can usually wind her out now to 7K without looking at the tach anymore. Just the sound will do it. All it takes is alot of redline practice runs (which I do every chance I get ).

You don't get much time in 3rd when you drop down into it from 70mph or so.

scalbert

The ECU would ne a re-programming to give you more revs.

If it bothers you that much just get the blower. That way you can be in a higher gear and still pull harder.

And no, the Unichip will not raise the rev limiter.

AND...

The problem with raising rev limit, when you don't have a lot of nice engineering help and tools, is knowing what is safe and what isn't with certainty.

At a minimum, you would need to talk to someone who has raced the car -- and I don't know how many people you will find that have built up a CL Type-S for race and/or strip cars with modified cams, valve springs, etc. IOW, you are making a very big assumption that the valves won't float; the bottom end won't rip itself apart; that the clutch and flywheel won't scatter (manual version); and you wouldn't be reaching the limit of the current cam's ability to flow more air. And, if the CL is like most engines with valves + valve springs, the cams are not necessarily in constant contact with the camshaft EVEN with the factory rev limit.

Get the blower. You will have more power, and people here who are working out all of the nasty engineering issues. Problem solved, and you don't need a new team of engineers.

Design-by-explosion will not serve you well (Someone will probably come along and tell you they got their Civic to 9K rpm and it was wonderful).

BTW, ever seen what a flywheel does when it comes apart?

Ditto... as was stated, the rev limiter is there for a good reason...

BTW... I've talk to some performance shops (including CompTech) and they say there is no advantage in raising the rev limit since hp/tq is already starting to fall off by the time you hit the rev limiter as set by the factory. This is generally true, unless you modded the heads, valves, intake, exhaust system etc... to produce more power/tq beyond 7K.

scalbert

I am eager to get on the dyno. The new manifold with shorter runners seems to have helped here as it does not seem like torque is ever falling off.

Please hurry.

The rev limiter is still valuable even to the experienced driver.

After over 4 years and nearly 90,000 miles, I hit it yesterday by accident. Not as often as I used to, but still...every once in awhile.

Now instead of the look of shock, I become resigned, place it in auto and slow down, realizing that I wasn't really paying attention to EVERYTHING and therefore shouldn't have been driving so fast in the first place.

derelict

I'd rather see some ECU hack which removed the 1-2 auto shift in the 5AT

ModAddict

Call and talk to Devin at Payn Tech. He went all the way back to an OBD-I ECU to get control of his 3.2.

Could this be the 'only' benefit of an Auto SS over 6spd ? I.e. never have a problem with a rev-limiter.. i.e. the thingy bumps me always to the next gear when @ redLine, and in the 3rd... I cannot help but get the thing to [spec'd] ferocious 103 at times... even when I do not always need to .
