Topout or Govener

Ok, I either topped my car out at 110-115mph or the govener kicked in. Im not too sure which one it was can anyone tell me? (At 115 it sounded like it kick me down a gear, slow me down to like 105, then I went back up to 115, and it kicked me down again.)

were your rpm's all the way up.

governer

lol before i set mines to 250 (like it would ever do it) i was racing this guy in a bmw and as soon as we got to 125 it started jerking and shit, then i couldnt go any faster, i was so pissed. the next day i whipped out the old hp tuner and kicked up the limiter :naughty:

118 your limiter kicked in.

yup, first time it happend to me, i was racing a mercedies SL500, like i had a chance in the RS, but we were in traffic (i know i know, it was several years ago and i was retarded, one of my realllllllly stupid moments.) and i held up with him till 115 when my car just stopped accelerating.

My damn Monte's guv is at 110-115 why the hell cant it just goto the seepometer limit?! I was racing this Plymouth Duster and I couldnt accelerate any more (I was at 110) and the damn thing just started going ahead, bastard.. I was winning too.

man, if only you could bribe a guy to update your PCM's program with the police version, it would allow you to run up to 126mph

Damn, I need that.

Also ever since THIS happend I NEVER race on the highway anymore, even though I know this really great highway too that has 0 cops on it and its like a 6-8 lane highway, and its always clear for some reason, enough to race on it anyway.

damn where do u live? when i use to live in ND we use to race on that highway all the time i think it was interstate 29. flat and straight for miles and miles. your radar detector could pick a cop us miles down the raod hell u could see them miles down the road if their were any. and nine time outta ten they didnt bother chasing u if they saw u speeding. nothing but farm land and a airforce base lol. great days in the eclispe back then

I live in TX, this highway is awesome but I dont go on it anymore because if I race on it is has to be like 60+ from a roll which is real bad for a 4 speed auto. Plus I found out when my tranny shifts its gears so I let off the gas and hit it again so it shifts like a manual, won LOTS of races because of it :D

you lift off the gas........... at every shift.......... and wind up going faster?????????

you lift off the gas........... at every shift.......... and wind up going faster?????????

Yes, like from 1st to 2nd I take my foot off the gas and then step on it again you make the car shift into second and it keeps the speed up like a manual, because I noticed that if you just keep the gas on the pedal the whole time in an auto when it goes into 2nd it doesnt move up as fast into second like it did in 1st, but doing this makes it go fast in 2nd like 1st.

........ im confused, but ill take your word for it, guess it has somthing to do with line pressure.

Dont know, has something to do with your computer or how your car takes it but look at like this.

When you drive and you slowly step up on the gas your car will go faster but not as fast as if you just step on it. (i.e. out of no where from no gas to full throttle)

Now when your car is about to shift, just by looking at the revs (and remembering the speed or whatever you do) you let off the gas quickly and then step on it again making it close up and WOT. I'll tell you what happens, instead of just going faster slowly into second like it usually does it jerks just like a manual does and thus goes quicker.

Just try to re read and try it on an auto if you can.

i hate that govenor crap... i truly despise it!
i know my engine will pull atleast till 150-160mph.
There's gotta be an easy way around it. It might take a while, but I will figure this out.

you need a reburned chip, but um, youve got a carbed setup, are you still using the computer to control everything???? just run 12v to your fuel pump bypassing the computer, the factory rev limiter is a fuel shutoff (which is good to know if your planning on running nitrous, nitrous plus spark, minus fuel = big bang.) so by pass the fuel shutoff by hardwiring the fuel pump and you dont have to worry about it.

third gens are not computer limited, it's a physical limitation in the tranny. according to TCI the electronically controlled 4l60e is also limited by the tranny throttle vavle. I'm pretty sure it's not fuel cut-off... that sounds completely different than the trans kicking back down into third gear. fuel cut-off sounds like your car is dying out. I don't drive a 4th gen, but from what they descrbe, it sounds like the tranny and not the computer.
I just found this....

No, in the 4th gens it is DEFINATELY controlled by the computer. I know this because your standard tuning/reprograming removes it... and also that i've hit it and it cuts fuel

okay... iwasn't sure about 4th gens, but I know 3rd gens are not limited by the comp. that makes sense since the tranny is computer controlled also. after you removed it how fast can you go? does it still kickdown into 3rd?

you cant "remove" it per say, but you can set it to 250, 300, 1000 mph... something you knwo you wont be hitting lol. I don't know abotu top speed, 3.8 speedometers only go up to 125, all i know is top speed is def. higher than that.

speedometers dont mean jack crap. thats one of my pet peeves.(i know you didnt say that it means anything you actually said it dosnt mean anything so im not directing thos towards anyone). but yeah i hate it when people are like my cars faster look my speedometer goes higher then yours!! thats how my x girlfriend was. shes like my cars faster then yours look it goes to 125 or whatever it went to and i think mine only goes to 110 or something.and at car shows people always look at the speedometer and go dang that car can go 220 or something stupid like that. and again no one said this 97camarors just made me think of it when he said 3.8 speedometers are lower then top speed.

yeah im sure mines go's way higher than 125 lol

I truly do hate what 88's talking about, pissed me off completely. "Oh it can only goto 120" what im thinking is "WELL F YOU, IF YOU DONT LIKE IT" but if even a girl says her car is faster than mine because of a speedometer, we're RACING!

lol, im with that... but then they will have some half ass excuse about they never raced before and they dont know what there doing and all that bullshit

They are WRONG. I have been burning 3rd gen chips long enough to know that the ECM does limit the speed. There were NO 3rd gens made with the 4L60E transmissions.

Lol I HAVE been challenged by girls to a race and thankfully they've all been hot so either way I see nothing bad from me losing or winning :D

Almost everybody I know thinks of top speed by the speedometer, not by power and what your car is actually like. Just like some of the current low power 4 cylinder cars, with speeds that go to like 150, but if you look at an old musclecar like an SS that goes to 120, they think their 4 cylinder is godly. That really kills me.

I agree, Xbox, is because they get narrowminded and think that how good your car is because of your speedometer, What they dont look at is that in those days the 4 speed was the 6 speed of today.

darn it morley, you beat me to it. you can easily tell the transmission does not limit speed, because the RS which is limited to 115 uses the exact same 700R4 as the IROC which is not speed limited (to my knowledge) and also, how would the manual transmissions automatically kick back to limit top speed?

damn straight! they didn't NEED 2 more gears!

Okay... I have driven my car to approx 130mph downhill in overdrive. and i have never experienced fuel cutoff, even though it's supposed to be limited at 115mph. This is why I say there is no computer limitation in 3rd gen trannys. And to my understanding the 700r4 limits top speed by not allowing full throttle engine operation in overdrive. it kicks back down into 3rd gear when you hit 75% throttle. and obviously, if you are in third gear you can't go as fast as you could if you were in 4th gear.

the trick here being that the car will not accelerate without more than 75% throttle in overdrive, but when you do more than 75% it drops you back to 3rd gear, thereby limiting the speed to approx 115mph. And the TCI throttle valve will allow this percentage to be changed. just as www.transmissionhead.com has a valve that does the same thing.

The only device in the 700r4 that is computer controlled is the torque converter lockup. And if there is no fuel cutoff (as it seems to me), there is no way for the computer to be the limitation.

So if yall know something that I do not, I would like to know. TCI nor TransmissionHead show that the 700r4 is computer limited. Nothing I have read says it. And from what I have experienced, there has never been fuel cutoff. Morely, IROC, Please explain.

thanks.

(by the way, i never said 4l60e came in a 3rd gen, I was just sayin that TCI is saying that 700r4's and 4l60e's are limited the same way, cause they both use the same TV valve to allieviate the problem).

Alot of older cars have the speedometer that only goes up to 80 mph but I KNOW for sure they are capable of going just ALITTLE faster than that......

Mine goes to 150. I can go faster than that if I wanted to.

But I would kill myself, I know better. :lol:

The transmission is not computer controlled other than the TCC lock up. Speed is limited by turning the injectors off in the PROM programming. If you've been to 130 without fuel cut off happening then either 1) You have a car that came with VR+ speed rated tires. 2) Your chip has been reprogramed/replaced. 3) Your speedo is off at higher speeds. Those are the only possibilities.
As for the 75% throttle in overdrive...I had better be doing one hell of a lot more than 115 in 3rd. It isn't in the valvebody, it is a little plunger device that you can modify so you can be in 4th and WOT. I wouldn't do this unless you want to burn up your trans since the fluid isn't lubing the trans enough in OD to run like that (GM designed it that way). There is a way around it though, it is called a "full time lube" mod and most performance rebuild's have this done.

also, something to keep in mind, is that overdrive gears do not have the same torque as other gears, thats why with the T56 transmissions, top speed is found in fifth gear, because sixth gear dosnt have enough power to match the speed of the fifth gear. thats why in quarter mile drag racing, you want the transmission in drive rather than overdrive, because once it shifts into overdrive it will be accelerating slower than if it was in 3rd gear.

Very true, my neighbor who has a 00 Z28 says his 5th gear is better than his 6th and has gone around 150, racing a Vette or something, I forgot.

I did replace my computer with an aftermarket one, only because I needed to. And i had H rated tires.

What is the process on the "full time lube" mod?

Sounds like I need to do this. I'm putting a trans temp gauge in my 700r4, so i'm not too worried about burning it up. It will warm me when temps start getting high.

And so, IROC, how does the 700r4 that is not limited do it? Can I just pull the valve body out of that one and use it?

Anybody know what my top speed will be in third gear? I know I can calculate it, but just curious if anyone knows.

You should've gotten a different tranny since you were changing the engine out, ya know?

On another note, I just got back from driving my bro's Jeep and my first manual lesson, man this shit is freaking fun and hard compared to auto, cause auto you just gotta hit the gas! Needless to say I did pretty good.

the 700R4 that is not limited operates just fine because the computer dosnt cut fuel to the engine..........

Rally Sport 92, I did get a different tranny. the swap can't be done without the V8 tranny.

Morely, got any info on the full time lube?

I live in TX, this highway is awesome but I dont go on it anymore because if I race on it is has to be like 60+ from a roll which is real bad for a 4 speed auto. Plus I found out when my tranny shifts its gears so I let off the gas and hit it again so it shifts like a manual, won LOTS of races because of it :D
its because it down shifts i done it with my cavalier befor
