remove speed limiter?

hi,

i got a PA SC 92 and im sick of that speed limiter... i know, i know, i shopuld not be driving at those speeds but i cant stand being passed by a 1990 rusty corolla who will do almost 120...

i cant understant why you can give this car good handling, and alot of power and be limiter to THAT.


is there a way to remove the speed limiter?


deadring

Whoa, theres a limiter? I've only had mine up to about 110, what happens at 120? Does if shut off the throttle?, it may just be out of power :lol:

hehehe no its not out of power. at around 115 to be precise the throttle just goes nenenenenenene and it stays there.. like it was cutting spark on 2 cylinders... first time i got it there my heart stop.. i thought the engine was goin lol

it can go ALOT faster. i just know it

deadring

Yeah, you can buy aftermarket PROM chips for that car which removes the limiter. Those chips can get kinda pricey though.

is it surface mount or can you just plug it in on the board?

kinda technical eh? ill check it out with a speeds shop around here.

maybe add a 25 hp while im at it :)

deadring

IIRC, all you have to do is swap that PROM chip on the computer. It's a lot like replacing RAM in a computer, if you've ever done that before.

yeah i know how to... i kinda work in that stuff.. i just need to weigh the fact that do i REALLY need it? :)

thats the hardest part :)

deadring

Do any of you know where to get one of these aftermarket PROM chips? Price range? Does it change anything other than removing the speed limiter? Any info will help.

Thanks.

from what i heard there all types out there...so add HP like 7 - 10 hp and remove the speed limiter. other just remove the speed limiter.

depends on how much you pay i guess.. i seen some around 80 US..not installed...

and since its CMOS most of the time you have to know what yer doin when installing one.. although i have heard that they are not soldered... more like on a base where you can switch one from another.. i have a hunch buick didn't make 5 kinds of
ECM's.. they must have one and the eprom makes the diffrence.. like if the car is SC or normal

Ok guys, Lets keep in mind a few things,

#1 that 3800 motor is a tough motor but not designed to be kept in high RPM 5000K plus for long durations. It is a street vehicle, and the internals are not forged or beefed up in any way.

#2 the trans is governed, and will not go faster than what it is designed to. It will run out of gearing.

#3 the chip upgrade if there is one, is expensive and requires other mods to go along with it.

Really, if your looking to go faster than 110 then you needs a 5.0L mustang like I have to do such things with a extensivly beefed up motor. Keep in mind, the PA is a heave 3000Lb plus car. Forcing it to much you will be paying $$$ in the end.

true..true.. im buying a bike or a sport car in spring anyway.. so i'll leave it stock...no cost would justify it anyway.. i dont go over 80 much anyways...

i do have the need for speed.. but a PA will not be the one to give it to me.. its confortable, its good for fast jumps on stop lights, and its got AC for summer and good heating in the winter..and its comfy :)

so i'll keep it that way

Deadring

He probably means Kilometers and not miles per hour LOL

Sounds good.. get yourself a 5.0L mustang 79-93 years.. Mod it up and you'll desimate all.. Thats what I do.. hehehe...

Why 5000 RPMs for long durations?? when i get up to 107mph it hardly touches the 3000 mark and maybe 4500 in 3rd gear. (97 PA)


#2 the trans is governed, and will not go faster than what it is designed to. It will run out of gearing.


That is only half true....i can't explain why and how but i know that zour answer is not complety acurate.


#3 the chip upgrade if there is one, is expensive and requires other mods to go along with it.


not in other cars like VW Golf and the like...it is very common in Germany and u can do without ANY other mods

i don't see WHY u need a 5L V8 engine to go faster 110mph....I can easly break the 120mph with a 96 Volvo 960 2.5L 170HP or a 89 Volvo 740 with a 2.32L inline 4 cyl. 116HP(ok...a little bit harder with that one because of its shape....not as aerodynamic as the other one or a PA), of course it's bit lighter than a park avenue. Hell, look at a VW Golf VR6 or GTI or even 1.8T.....they are flying man and they only got small 4 bangers or a SMALL 6 cyl.

Please tell me WHY u need a V8 to go over that 110mph mark!

PS: I drove the Volvos when i was in Germany a few months ago. My uncle is a huge Volvo fan and so am i ;)

well.

its true that at 107 on my 92 pa SC i wasnt close to 5000.

its also true that a VW golt GTI 1.8 liter turbo can crank up to over 130 MPH... ive been in one.. i know it modded but still CAN do it.

my previous car, was a old corolla DOHC 16 valve with a high flow cone filter ( which now is in my PA) and could reach 117-118 MPH..not quite that 120 mark... but it weighs also ALOT less..more like 2300 LBS...which is a alot less than the 3600 LBS dry weight on a PA.

u dont need a V8 to get tto that speed its true... but u got to admit... with either a five point 0 v8 or a turbocharged engine, it will make it ALOT eaier to CRUISE at high speed... my corolla wasn't built for speed.. witht he stock filter i was lucky to hit 100 in fifth.. with the filter i could hit 106 in fourth..all the way to the rev limiter at 6600. without any probs..

the thing is the car is TOO heavy, the engine is not made for high revoltution but torque atr low range and the gearing is far too high ( on my 92 it is.. i think when you get to 98 and up the gearing is better for accelration) and to top if off is a luxury car. :)


as for the thing that u can put a chip in a buick wihout modding anything i dont believe its true. exept maybe for a cone filter. the exaust diameter is BIG.. mine is either 2 ¼ inches or 2½ inches.. so for the flow of gaz with got no problems there.. as for intake, well , i got a a sucpercharger with blowing 8 PSI in and for less intake resistance , a cone filter.. if i would put a chip in it, it would be for removing the speed limter, not get more HP. it doesn't need more of that to reach 120..

OK were talking GM here ok, Imports are a different story and I own a saab 900 Turbo 16V and I will smoke all these imports around here with a 15psi of boost and a aftermarket APC box. regardless, Mods have to be done to keep them running, just a chip alone will eventually get expensive. Plus off the line, My 5.0L will kill any import off there if I can keep the wheels gripped. 425RWHP is alot to get keep planted. And also the Vr6's and the Turbos, they are 5spds.. keep that in mind... How can you govern a 5spd? You can't. unless the computer cuts the revs. no automatic without mods and chips is going to do serious speeds. Volvo and SAAB and even VW are a bit different then Honda and all the ricers. But bottom line, Cubes always wins and will last longer. 107 on a PA in OD is above 3000K. no question about it.

ok i don't want to start a fight....

imports are different...most of them are designed to go faster than 110mph

well even with a high torque mustang v8 it is impossibble(my opinion) to loose grip at 110 mph. in a case of 0-60 i totally agree!

ok...i also drive a 4.6L V8 Ford Explorer with a 5spd auto. It behaves exactly the same at 107mph. I don't quite get your point here but if you mean that a 5spd would 'cut' the power just like you say the PA does then this tells me that u r wrong.

didn't want to say it before but i've never seen an engine rev at 3000000 (=3000K) or 5000000(=5000K). you most certainly mean 3k and 5k just to let u know.

I'll post a pic or vid that shows that my PA is reving at about 2900 and not at 5k+ like you said in your first post which i replied(even 125mph get me near 5k mark in OD). get to 107 in 3rd gear at 4400 or so and red line is at 5600.

again i don't mean to start a fight i just want to point out a few facts that i expirienced. it could very well be that i'm wrong in terms of transmissions but hey i just want to state my opinion and i hope u accept that and i'm interrested in what u think about them.


fischmama

well in a way you can governe speed with a 5 sp.. itS' rather easyyou install a limit switch on the tranny that tells the ECM that the car is in fifth gear.. and then cut some fuel/ spark..


i know , i know, u can reach higher speed in fourth then.. but still.. it can be done.


on a bike, a suzuki gsx-r 1300 hayabusa, they limite the bike at 299 km/h which i think is completely stupid..anyways, they do by reading is the bike is in 6 gear and then, it gives less fuel on clyinder #1 so it makes "hang" the engine gently...you cant just put a rev limiter on abike that goes nenenenenenenen and shakes the whole thing @ 299 km/h when you got a square inch on tire on contact with the tarmac for each wheels :P

deadring

Oh i am not starting a fight with anything, Yes when I mean 3000K i meant 3K.. That is my bad. and 110 breaking free, I wish, no from a start keepin the tires planted is a problem, even with steeda control arms and 17x9 wheels its still an issue. As for the 5spd, 5speed Manual is different to the 5spd Auto. The explorer has the 4spd with AOD which gives you an added shift which in reality is just the clutch locking in the converter obviously. But a 5spd in any car will handle higher speeds on the street. And yes if you remove the speed sensor on the trans or bypass the reading to the ECM ( which of course I did ) your limiter is gone. This is on MY 5.0L mustang not the PA which uses the speed reference to shift. there is guy in town here that has a 99 GTP supercharged obviously that has a sick CAM .514 lift @.050 duration, with 22lbs boost, all forged and polished 3800 v6 the trans was beefed up to a rediculous state, i forget what he put in there, carbon fiber clutches and what not but the car is rediculous. it sounds like a big block chevy it has side pipes with a 30 series flowmaster. He made his own 2 inch headers, all custom and the ECM was totally tuned, dual ignition setup, etc. I mean if you seen this car and what the 3800 can really do its rediculous. I mean really the 3800 is a smaller version of the 350chevy with 2 pistons cut off. This car though is sick! Looks like a big mirror when he opens the hood. he says its impossible to drive due to traction issues and Torque steer is impossible.

to really se the potential of a 3.8 you can look at a buick GNX - GNR.. these cars where sick too.. i know its an older version but still..:)

it had power. :)

Deadring

Whats a GNR? No such thing.

err sorry about that GNR does not exist, i meant GN..as in grand national :)

My bad

deadring

Well of course a Grand National (GN) has the HP, the turbo charger is set with a decent amount of boost, plus the short intake path and high riser makes it all the better. But yea the Block itself is an extremely similar platform, but the internals are alot beefier. Plus RWD makes a difference too.

ok who wants to earn some money and put all that stuff the GNX has in my 97 PA?? Create a PAX so to say...

j/k

If you ever put that kind of HP in a PA your trans would be toast!! :)
