remove speed limiter?

deadring · #1 11-04-2004, 12:26 PM

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?

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

deadring · #3 11-04-2004, 02:57 PM

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

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

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

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

He probably means Kilometers and not miles per hour LOL

parkavenuechrome · #13 11-10-2004, 11:09 AM

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)

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

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!

Thx,

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..
