When I am in park and I press the gas does the engine only go to 4 and then drop down and go back up and drop down again? Is there a way to allow it to go to 6?

hmm, maybe you have to be rolling. probably is tied in with the wheel speed sensors. you're not gonna be able to "fix it" it isnt broke. and if you did change it, the only thing you'd end up fixing is your engine. it's there for a reason.

well alright. i never said anything was broke. but i usually have to be going about 20 to 25 mph or more to rev past 4000

I can get up to 6500 RPM when in drive but thats only when I gun it. Once at speed it goes down never gets past 3000. Could the idle RPM level be edited with a computer to run up higher like 5 or 6?

You guy really want to blow your engines huh?

Why do you have to rev it over 4000 when parked anyway?

glowbot
09-14-2004, 10:56 PM
LOL don't know. Just want to know I can I guess and wondering why it does not allow for it to go higher.

FutureEcotecOwnerAgain
09-14-2004, 10:59 PM
as long as i dont go past my redline i'll be aight. reving to 6200 instead of 4000 in park or neutral is gonna make the exhaust sound louder because of higher rpms. plus i dont like when peeps rev theirs and get to 6 and 7000 just sitting in park and i can only go to 4000.

it is a factory rev limiter in the factory PCM. the only way around it is to have your PCM reprogramed. and right now that is only available for the 3400

glowbot
09-14-2004, 11:05 PM
lol I know. My van can get up to 5500 in park but this is not the reason I wanted to know why. I just want to understand my car a bit better why things do what they do.

WOOT I got a 3400 SFI. Where do I get this done?

dunno why you would want to put the extra stress on your engine, but the ASE chip gets rid of the rev limiter too.

Not officially it doesn't. ASE doesn't advertise it either, but for some reasom my ASE'd PCM does (at least it did last time I ran it). My DHP has the 4000RPM limiter, but they will also take it out by special request.

So where would I bring it in to get the code edited? I would like to get my system tweeked as well. How much does this normaly cost to do?

Rev limiter so when your not moving you can t blow your engine or put stress on it that it doesnt need its GM's way of giving you some piece of mind. it can probably be fixed with a simple Computer/Chip change to a performance one without a rev limiter and govenor.

ya Don't want to blow my engine or cause damage. Just like doing mods and toying with the car see how things work. I would like to get a old junk car that runs and rip it apart then see if I cant get it to work again. Might do this next summer.

there is no good reason to want to rev your car to 6k rpms while in park, except for the fact that you're probably some ricer. the search function would have definitely covered why u cant do it.

Thanks but there is nothing I found that says 6000 RPM well do any damage other then put a bit of unneeded stress on the engine. There was one post that said 6500 could cause some damage but nothing about 6000. Guess I need to bring it in to get the cutoff set to 5500. Don't think I want it to go higher then that in neutral or park. 6500 max in drive. Want my car to sound a bit meaner is all.

Not sure about everyone else but when your in your car with a girl you just met and some damn 4v Honda/other comes up beside you and revs their engine at a light showing off and you got nothing to put back in their face its a bit embarrassing. I do not support street racing therefore do not engage a car when the light goes green. This means gun it when the light goes green. I have seen first hand what can come of this.

Soon I well have a supercharger installed in my car but till then I would like a alterative.

Thats not a good way to show off for a girl. Get her flowers instead. I know what ive got under the hood dont have to show it off. Any1 wants to race they know when are where. At the track.

no one is ever sitting at a red light..........maybe a bunch of friends in 2 or so cars......the other one pulls up next 2 u giving you the eye and revs up to 5 or 6 grand..........and you can only do 4........

its just the thought of another limitation on your car that sucks......

Travis99Alero

revving your engine while at a redlight isnt going to impress too many girls, it's only going to confirm their suspicion that you're a ricer. for example, when i pull up to a light, ordinarily i'll sit there and be normal, but if i see some ricer, or if the ricer is dumb enough to start revving his "4V" as u call it, rather than be gay and rev also, i'll just hit some switches/lay the car out. it will impress way more people than revving up to 5.5k rpm will, and wont make u seem like such a ricer.

Called power under the hood. Don't want my car to sound like poop and that’s about what 4 RPM sounds like and even worse when it hits it and drops back down really fast. Almost sounds like my dog when she’s getting ready to vomit.

Anyway thanks for letting me know dangerous this can be for my engine and giving some really good reasons not to do it other then being a ricer as some of you put it.

Does anyone have a valid reason why not to do this other then some of your guys hate for "ricers"

It's a waste of gas and will wear your engine out faster. It'll heat it up a lot faster on a cold winter day, but a temperature change that abrupt can cause metal to warp and/or crack.

I really did want a 5 speed. My next car for sure is going to be one. Not asked the question yet but is it easy to convert auto to 5 speed?

I am not saying I am going to rev my engine 24/7. The odds are it would only happen a few times or just showing off to some friends. Not only that but I live in VA we really don't get much of a winter here.

Well they are valid reasons, though maybe not very significant. Either way, it sounds like a lot of work and money for something that you can only see being used a few times.

bigd6983
09-15-2004, 05:17 PM
i dont think a quick rev is going to cause an amount of enough to crack anything........and i dont think revving on some friends categorize's anyone as a ricer.......a ricer is someone who cuts corners......gets things done 1/2 a$$, cheaply done, just poor quality......revving does not constitute a ricer at all.......

and i agree, revving doesnt impress girls, i dunno if it was said up there but i never said anything about it........

i agree that it isnt worth the money just to get rid of the irritation that you cant rev past 4 grand at a stand still.....but just having the ability to.......

another thing.....you ever done work on a car such as intake, exhaust, or whatever......and want to hear your engine as soon as you start it up but cant hear fully what it sounds like??

just things like that.......

If you have a CAI and exhaust then reving up to 4k will sound good...
Get the computer chip if you want to rev past 4k. But i agree flowers will impress her so much more, or something along thoes lines.


Revving at a light sounds a lil kiddy... do what you want man its your car, i doubt it will cause ALOT of damages just some non-needed stress

I dunno, but I think just a card works just as great and is a lot cheaper........

its crazy what just a random card to a gf on a non special occasion will do.......

hmm, mine sounds great at 4K. near redline it actually sounds worse, and close to 6000 gets to the point where it sounds like it could blow up. haha.

OK I get the exhaust done then see if I should do anymore. I think I can do this on my own. Does anyone know where I can get the pipe. Also what would be a good system to put in. I want something deep very sporty sounding with dual pipes each side.
