6200 RPM cutoff on RL

gmsky · 11-24-2006, 03:20 PM

Is there a way to make that fuel cutoff go up or disappear on the Redline? I realize there are possible ramifications to my warranty, but I hit that fuel cutoff point twice and it's like a kick in the jewels when it happens.
I'm not looking to redline the Redline, but I'd just like to have a little margin of error in case I'm a little slow on the shift.

If this is supposed to be a safety feature, it sure sounds dangerous

. Does it shut of the instant the tach goes over 6200 RPM? It would make more sense to me if it was tripped only if the tach was over 6200 RPM for more than one or two seconds.
Not owning one nor having driven one to know for myself, what about this scenario: You're stuck in the slow lane behind a slower car so you downshift, stomp on it, and pull out to pass. You're telling me the car will go

and shut off if you pass 6200 RPM? Meanwhile the guy behind you that you cut off nails you from behind? (I, by no means, condone this tactic

. I'm just wondering what would happen).

That's a very good analogy. I'd like to know the answer to this as well.

If you are hitting it often enough for it to be annoying, you should be glad that it is there, or you would have certainly toasted something by now.
Get a feel for it and learn to shift without hitting it.

X2 on this one. Look at it this way...it's saving you from yourself. Far better to bounce off the rev limiter at redline than a raised rev limiter above it. Do that too many times and you're going to severly shorten your engine life if you don't damage it right out. I'm sure there is some margine of safety with that limiter but I wouldn't risk it anyway.

Now to your question. Yes you COULD raise it if you have access to a tuner that can edit your ECM...namely Vector. Not only that, but I would talk to him and see if this is a fuel cut off or an ignition cut off. I HOPE GM would do an ignition cut off rather than fuel as fuel cut off rev limiters are, in my mind, not a good idea. Our Grand Prixs have, from the factory, a fuel based rev limiter. However it is capable of being switched off or switching to an ignition based cut off and is one of the first things we do. Of course, with an Automatic Transaxle it's not as critical as on a manual transmission but the idea is still the same.

Bottom line is keep it where it is at and learn to anticipate the shift. Your engine and your times will both benefit from it.

gmsky · 11-24-2006, 05:29 PM

I don't cut people off. I figure if there isn't enough time to use my signal then that's a "cut-off". This was just straight line stuff and the only way to never hit it really is to stare at the tach (also not reccomended)
It IS a fuel shutdown, so it's a dramatic slowdown.

snaponbob · 11-24-2006, 06:30 PM

It IS aggravating, but true, 6300 rpm (not 6200) is the rev limit. As fast as it comes up in 1st and 2nd, and as quiet as the exhaust is, it is a bit of a pain. And the cutoff is sudden because of the short gears. I have found that one gives up NOTHING by shifting at 6000 rpm because the engine has SO much torque. Guess what? It is a REAL issue when autocrossing. Been dare, done dat! Get used to it. Unit someone unlocks the code in the ecm software we are stuck with it.

From your starting post, I was under the impression it was like getting clotheslined in football. This sounds more like it.

Now that I think about it, a fuel shutoff is exactly what happens when you take your foot off the gas, only to a further degree.

I have hit fuel cutoff a couple of times in my "base" Sky. It's no biggie. It's not like the engine shuts off and leaves you stranded. As soon as the RPMS drop, the fuel supply is restored and you go on about your business, making a mental note to pay better attention in the future.

Note to self:

figure out a "shift light" for when my sky comes in

Someone out there must be able to make this mod for us. It would be very usefull.

Devoking · 11-24-2006, 07:08 PM

I know that some have reported that the turbos seem to be very quiet, But with a little practice you should be able to drive by sound and not have to stare at the tach. It will all become instinct after awhile.

**JohnD** · 11-24-2006, 07:13 PM

I don't hit it any more... As I learn the car, I know to start the shift as I am coming up hard through the 5000s... The power drops off there anyway, so it makes sense to shift out before bouncing on the ceiling.

Yes, the louder note of the 3" Magnaflow helps in that regard. It sounds "right." It does still get to the high RPMs awfully quick, though...

I let a buddy drive SPIRIT yesterday, and he bounced off the Rev Limiter. He was surprised how fast it got up there. But there was no violent reaction or anything - the car just stopped accelerating. AND - there was a cool "Pop! Pop! Pop!" sound coming from the exhaust when it did it.

I certainly like having the Rev Limiter there. I don't hit it very much any more, but I know that it is there for my protection.

MidniteBlues · 11-24-2006, 07:17 PM

This problem just does not happen or exist with an automatic--

I suppose I can cram it down her throat by "maually" changing the auto and push the rpm's, but why bother to mess with perfection??

Stick it in D and just SToMP the mother--

No fuel problems--(as long some in da tank)

I'm an auxiliary cop, so I just kinda never wore seatbelts very much...but this Sky has trained me to do so when I drive it because of that annoying "bing-bong" whenever the bladder under the seat moves around. Is your display actually showing the door ajar statement? I didn't look, but it's usually just a stupid little switch the door compresses on that the thing is looking at.

"HEY KID, you'll shoot your eye out!" Guess it's the risk I took asking about this. Anyway, GM's data shows the peak HP at 53 or 54 hundred RPM. I have it all printed out for both motor options somewhere but I'm leaving now!

Yeah, I know my power curve pretty well after all the controversy it caused when Magnaflow posted the great results of the 3.0 inch Cat-Back exhaust that they fitted. People just could not accept the gains as real. But I can feel them. The dyno below is from my very car. (the blue line shows stock, the red line shows after the monster exhaust is installed.) Notice how the torque drops off after about 5200... I start to feel it there, then by the time I react the RPMs are in the upper half of the 5000s, and then I release the gas, press the clutch and downshift to the next gear. I'm actually starting to get it right now. Whenever I go back and drive BABY, though, my brain resets and it takes me a while to get to learn SPIRIT again...

SKYGAZR · 11-25-2006, 08:43 AM

Now with 1000+ miles on my RL, I never hit it anymore....

You just get used to it and I trained myself to clutch at 6000rpm and this gave enough time before she reached 6300 and cut off...

Now, I just know by the sound of the motor and the car's pull when to change....

It is simply a matter of getting used to it.....

It has been confirmed that you are a troublemaker. Your penance is to remove from your car the source of all this trouble and ship it to me. Apparently you are NOT mature enough to handle the stress of ownership of such an item, and I am. So, please allow me to relieve you of your burden. It is a sacrifice that I am willing to make, and your life WILL be simpler.

Aurilious · 11-25-2006, 10:34 AM

Fuel cut will have the same effect as ignition cut (eliminate a cylinder from producing power), except if you only cut the ignition you will still be flowing fuel through the engine. This can be used as a turbo lag solution, but it can be detremental to the turbo and exhaust components to be igniting fuel directly on the turbine, or catalytic converter for that matter. Be glad you only have fuel cut.

RED SKY NORTH · 11-25-2006, 12:48 PM

i used to experience it at the end of second but you train yourself to shift jusat around 6000 . The engine seems extremely strong however and its as if GM left alot on the bench with this one . I'll bet in the next couple of years they will tweak another 30 hp out of this motor . Id be interested to see if an after market company could make a chip to safely manage this additional HP I feel is sleeping comfortably inside this little 2.0 monster .
