Top Speed Limiter, How do I remove it? Options

[JoKeRkId613]

I have a 1994 ST Auto. If I'm not mistaken, there is a speed limiter of 111MPH because of the tires the car came with or whatever.
Reference:
http://evilspeed.com/Speed_defeat.htm
The problem is, this article is for Manual transmission STs only. It says if I were to do it with an Auto transmission, it would **** it up. I was wondering if anyone knew how I could remove the top speed limiter for my auto tranny celi. Thanks!

[Bigmeanbulldog55]

Good luck ever getting to the 111mph limiter on an ST, or a GT for that matter. It would take you forever, and you really don't need to be going that fast. Unless you have other significant upgrades, and I'm guessing you don't from what's in your info, you'd never need to remove it. I don't mean to bust your chops here man, I'm just telling you how it is.

[slipgun]

hmm.... I got up to 110... it takes a while leme tell you... I never noticed a rev limiter but your sayin its at 111 so I duno

[94ST2]

Yeah it stops the manual st at 113. You would probably never go that fast in a 1/4 mile race but it is fun to see how fast you can get the car to go, but its more hassle than its worth because I doubt without major upgrades that you would get to 120 sumthin maybey 130 so not even much of a difference.

[Blakout16]

i got my st up to 120.... i dunno what u guys are talking about... lol manual tho and its a 94... i dont think we came with speed limiters.

I've gone past 111 in my ST... not that hard... I don't know about an auto though, you probably shouldn't touch it.

[macavely]

what the hell are ya'll talking about about .. when i had my ST-auto .. i was hitting 115+ all the time comeing home from school.... yea it took a while to get up to that speed but up till 90 it was pertty quick ... and on the GT-5spd... i gotten to 120 with no problems... fairly quick .... maybe some of ya'll need to learn out got get ur cars to high speed the right way .. its just about smashing down the throttle ... and before anyone says i shouldn't be driving at such high speeds.... keep it to urself...


edit = and to those of u that want higher speeds u will have to regear ur tranny to get anyother noticable out of it....

Well on my 94 st its not about not knowin how to get up to top speed or that the gear ratio should be changed it just gets cut off when it hits 113 just like it cuts off at i believe 6500 or 6800 rpms in any gear. When i said he would be lucky to get 120 sumthing maybey 130 I meant without major engine upgrades he would be able to go faster than that.

engine mods won't make the car go past its limits it will just get it there quicker... and i think the CA cars have a lower speed limit then the rest of the country ... so if u can only get to 113 and shut off doesn't mean other can't go past it... cause i should did when i had my st ...

[94ST2]

Good point california rules are gay. Not every part you install will get you a higher top speed but come on now when you get certain engine mods that make significant gains in hp then your top speed is gonna be raised.

[trdevelopment]

i once did a 134 in my st.

[right][snapback]279867[/snapback][/right]

well yes if those mods affect the ecm ... in some way .... but then again speed is controlled by the transmission thats what spins the wheels not the engine..... thats why race teams speed 100's of thousands of dollors on transmissions...

[94ST2]

Good point.

[CelicaST18]

The ST has will hit the REV limiter (not the speed limiter) at 126 mph because of the gearing, however the speed is governed at approx. 116.

The GT tranny goes to about 120 and poops out.

[playr158]

my ST is rev limited (oh and you can't rev up to 6500, or 6800rpm on a 6gc fyi) well maybe on a gt ST's can only go to about 5800 which sucks so if sumone knows which wire to cut just freakin tell me already
cause at 115-120 i don't wanna be hitting that stupid cut off

i have a gt and i've hit 123 mph, and i got a ticket to prove it. btw my car is bone stock except for my rims.

[yarik83]

my car does this:

0-30 -slow
30-80 -fast as hell as rpms go waaay into 5Ks
Note vibration startes at 70 and dissapears at 80
80-90 -you dont even feel like you are speeding up
90-115 my car tries to balance itself which pisses me off.. it tries to maintain its speed at 3K rpm.. finally as soon as it hits 115 it wont go no more.... starts to slow down but you can keep it at 113 if you keep your foot on the gas.

I heard there was supposed to be a computer reprogramming device. They have th0ose on ebay but obviously i would never trty something that has no manufacturer's name in auction.

[darksecret]

I've hit about 125 in my GT and pegged the tach, 4.10 gears suck. The ST manual has about the same gearing, and the auto is around 2.xxx so it should be capable of going past 125mph.

You guys are acting like it's easy to get to up at those high speeds. It's not. I've done around 125 in my celica, but it took forever. The car can cruise at 110-115 alright, but there's not point. It's just not a good idea to go that fast, especially if you don't have proper upgrades. Whatever though, go kill yourselves, there'll be a few less idiots for me to deal with.

[macavely]

lol OMG the thread has me on the floor rolling .. thanks guys i needed that laugh ..

[darksecret]

I could understand removing a limiter if there would be a significant increase in top end, but on the ST it really isn't worth messing with, the full size Chevy and GMC trucks have an electronic limiter that can be removed with a programmer. The factory limit is 100mph but after the mods I could get mine to 140mph before it would start to top out, I never pegged it though.

[JoKeRkId613]

ok...?
so how do you remove it on an automatic st?

[darksecret]

On older vehicles there is a speed sensor located somewhere along the drivetrain, but i'm not sure on the ST, the older non-Vortec Chevys had them in the rear left axle. Actually the shield behind the drum was the sensor.

[st_celica_killer]

urgh .. .....just go buy a greddy speed limiter cut controller ...... that well do the job.....................................

[dustin15brown]

I think the point should be... dont screw with it, you're askin for trouble

[playr158]

nah its not a big deal its 1 wire that you just hook up to a switch to cut it temporarily b4 it hits the ecu its really no biggy
and it really doesn't take that long to get up to 115+ mph

and proper mods?
umm a decent alignment and balanced tires you should be fine lol just don't wack into any pot holes or cars lol

and hmm maybe me in my ST doin 130mph
with my suspension dropped on its balls and 18" rims will fly past bulldog and drop him into a tree? one less hillbilly to deal with

get a grip high speed doesn't mean a thing anymore unless its in excess of 150mph
my ST is prefectly able to hit 140.....given the time cause oh wait we're not lookin at a performance motor? well that is until i get my 7afte project finished then hehe goin past 130 will be easy

[StreetRacing10PS...]

if you are doing regular street racing 100 is all you really need. past that is just crazy because you dont have much time to react. and the most i really race is light to light which isnt possible to get to 100.

Hey, I see were your going with this. You live in northern Virgina, and I live in West Virgina. It's really not that far away. Come on up here. Or I can come down. You want to talk like that, then you'd better back it up. It'd probably be quicker for you to get here sence you can run that 130.

pretty common mod to me.

[94ST2]

There is a link at the beginning of this on how to do it from evil speed. To the person that said that on an ST you cannot rev up to 6500 or 6800 I sure can and Ive hit 7500 when I missed 5th and went back to third.

[prez]

the only speed limiter on my st is that stupid little nob thing that resets my mile guage so whenever my speedometer gets past the 155 it hits that thing and cant go any farther... and plus there arent anymore numbers... can i mod that somehow?

[right][snapback]289195[/snapback][/right]

your saying you hit 155 mph before? lol well i have a 94 st manual and once i hit about 115 it was taking for ever to go any faster but then again i have bigger rims and i loked it up and its about 1-2% off so i was actuallu goin a lil faster then 115

[darksecret]

I would pay to see a stock ST hit 150. I would pay to see a stock GT hit 150, lol, I guess i'll be keeping my money on that one.

[red94celicagt]

yea that si complete B/S, you would be redlining easily by 120..even in a GT. The fastest I've ever gone is 110 on this little stretch of highway going downhill...I was around 5k RPMs...I know you can't hit 150 without seriously F*cking up your engine...if not destroy it

[darksecret]

The GT is limited to about 125 by the transmission. The only stock transmission on the USDM Celica with the right ratio capable of reaching those numbers would be the ST Auto and it is lacking the fifth gear to reach them, so mechanically you have to either have custom gears or found a 5 speed transmission that would bolt up to the 7A with at least a 3.10 ratio.

[tomazws]

Why the heck they put a speed limiter if our cars are THIS freakin' slow.

I mean, if I get on the freeway, gas that crap like crazy... I don't think my car would ever reach the speed limit of 111 or whatever till after like 20 exits.

[prez]

i was jokin, but i got past 140 once, i wasnt redlining, i was goin slightly downhill on the highway in a 94 auto st with a 7afte engine, and i believe the speed limiter has been removed, the mechanic who looked at the car before i purchased it said the engine was swapped perfectly but didnt know why he couldnt get the check engine light to turn off... but hey next time i get up that fast ill try to take a pic for ya guys, if i dont come back i crashed trying lol :-P

oh, and no im not trying to mod it so my speedometer can go past 155 lol, ill remind myself to add the jk at the end next time

[94ST2]

How high can you guys rev up your engines in the st?

[vykiod]

so you now, i've got my stock 97 gt convert auto up to 128 in about a mile's distance, it was setting just under 5k rpm's so it must have some rev limiter

[darksecret]

Maybe the auto, try that in the manual and you'll redline.

[celicaracer18]

the st is rev limited but i'm not sure to what exactly.
the speed is governed (limited) to 110 from the factory, but different size wheels can affect that.
HKS makes a speed limiter cut for around $45, mabey cheaper on ebay.

also if you have any upgrades and want to moniter your performance, i suggest a APEXi RSM, it has a speed limiter cut built in and can measure all performance numbers. just be prepared to deal with metric numbers.

and i got me celica to 130 with intake and exhaust, it wasn't that fast but i did get it there, and yeah mods won't make you go faster because its usually the tranny that resticts speed, but some cars run out of power before gear, just not the celi.

[94ST2]

Im almost postive that the rev limit on the st is 6800 or close to that.

[94CelicaRedHatch]

fastest ive got is like 100-105. I dont need to go that fast cant chance another ticket

[Illyont]

I have been driving uphill in my 99 ST at 115 mph. There was no problem really coming up to that speed. Not sure how it would have been going any faster though. But I was still only using my fourth gear, and haven't reached rev limit yet either. (this is with no real mods, apart from new rims and tires. And of course removing tools and spare tire etc from the back)

I'm not sure, but I think that the Europe version is more like the JDM version than the US really, because of several things. And I think we might have a tad more than the US version under the hood.

Cali cars atleast are a bit slower than regular, aren't they?

[playr158]

EURO 7afe - rev 7k
USD- 5800 or 6200

[94ST2]

California cars arnt necesarly slower we just have more emissions to deal with, but when it comes to top speed the limit is set lower i think than others. As for my redline its around 6800, but if player is saying 6200 it could be, but im pretty sure i can go higher than that. Im going racing tomarrow anyways so we shall see.
