OK....So the New Yaris is all broke in and I'm winding her up 140,150,160,170,180.......185 KM/Hr.:eek: And someone pulled the plug.
What gives.....Now I gotta get a chip or something ????:frown:
Clocked this on the GPS to make sure its accurate , and YUP right on the money 185 K. No more.:thumbdown: Dammit, a fella should be able to decide how fast he actually wants to go........So I'm a speed freak.....yup. Got the room and the roads ....so why not.
The question is who has the cure and where do I get it ??????

I know theres a device that you can install to your car. Its like a parent child thing. The mother/father can acually know how fast you are going on the highway etc on this little mobile thing. And if your going over the speed limit they can shut down your car by the mobile.
I saw it on the news :)

Ya I remember hearing of that. It sure would blow if I had it on my yaris but good thing I don't :thumbsup:
I dont understand why they would have a device a cut off the car,wouldnt that put alot of pple on the highwy at risk,not to mention the child your doing this to,that you love so much they could easily come out with special keys that lock or unlock the potential of the car(2 keys,one ignition),or Im sure in a few years we will have thumb print tecnology that would do the same,becuse if the car had a 60mph limiter all the time,the car would be useless.Anyway,I got mine upto 115mph,stock,Ill try again soon,with some more performance part,Im waiting on Megan headers,and some other stuff.

sports car are built and designed to handel thoes speeds not an econo box.

Guess if you r scared of a little speed or cannot handle the equipment .....Yeah.... "YOU" might be an idiot.
I don't remember saying I was doing this on a congested hiway,service road or residential street.
I'm old enough to know better, and have enough time under my belt to know my own limitations. ( check my garage ) :bow: Horse power and speed have been in my blood from the day I had my first bicycle.
I only just finally released hold of my pet Mustang ('89 5.0 litre GT ) which I had owned since 1990. And this car I have taken up to 276 km/hr, (quite regularily) ................................
Anyways, without gettin further into it.

You own a Mustang and think the yaris handles good at 185kph? LOL
I own and have owned a lot of fast cars and some nice sports cars and in no way would I ever even think about comparing the handling ofthe Yaris with a sports car at speeds over 100mph ,
Hell a tiny side wind will try to push the car all over, hit a dip in the road and that electric steering will get caddywompas REAL FAST. The wheel base is short and the car is not balance well enough for high speed handling.
Are the tires even rated for over 120mph ?
More then just being able to handle the car at these speeds it's drivers that are careless that boost insurance costs. Maybe you have not been caught yet but if and when you do i'll thank you now for increasing all our insurance rates again. It only takes a split second for someone to pull out in front of you or even a deer to step out on the road and it's all over. Speeding and drunk driving are the top two resons for fatal car crashes or acidents involving other motorists.
I guess some people just don't like people bragging about having no regard for public safety or local laws...
Then again I can't say I always obey the speed limits. the fastest I had my car was on my uncles private road aprox 2miles long

eco, some things are not preventable (well, maybe exercise and eating right => live longer) but EXCESSIVE speed IS preventable. If everyone was going at 180, fine. But when there are a great variation in speed between vehicles, and it only takes one thing to go wrong, and it's goodbye road, hello coffin.

Just dont speed in public rds, its plain stupid and you prob need to get shot for speeding on public rds cuz i know a friend of a friend of a friend of mine, he was going 140KM/H in a 50KM zone and he hit this mans leg while he was crossing.

I agree completely, I thank God for the Yaris' good braking, we almost had a run in with a deer the other day, in the dark at only 55 mph. Stupid thing just stood there till the last second, we came to a dead stop with the front probably missing the deer's rear leg by about 2 or 3 inches, and that was braking from what seemed like only 2 feet away, but it was probably a greater distance, I hate those slow motion moments when there's something ahead and nowhere to go on either side except a metal guard rail and a concrete riser.

Back to the thread topic (damn to all of you thread snippers)
There was atleast in my intrepid a device called a Governor which would stop your engine at a certain speed. All you had to do was remove the governor and there goes your "speed limit"
barryware
10-25-2006, 11:03 AM
Now that we are past the "Speeding Is Bad" thing....
I can not speak for the Yaris as I have never tried to see what the "electronic limits" are. But most cars today have both a rev limiter and a speed governor.
For instance, my 03 Ford Sport Trac, while sitting in the driveway in park will not rev past 2700 RPM. The rev limiter starts firing every other injector to keep the RPM's low. I have a 99 Accord where the engine will not go past 6700 RPM or so. I don't remember exactly but when I was playing with it in lower gears to feel the VTEC kick in, the engine started cutting out somewhere below 7K.
Again... I don't personally know but a friend of mine states his corvette is limited to 140 mph.
There are performance chips and/or modules available to circumvent the controls. I could see the bypassing the MPH but I would rather keep the rev limiter in tact. It has happened before where I am hauling a$$ down the highway and the wife has hit the shifter (by accident) reaching for something and the car went into neutral.. I actually pulled over to listen for a rod knock. Glad the rev limiter was there.

I also hate Governers... here in Ohio there are 2 jackasses running for Governer :)... Oh yeah... wrong Governer... anyway my 00 Blazer had a speed limiter @ 95mph, my wife 03 Alero has one at 115 mph as well... when I hit 115 in my Yaris I can tell she still has some more in her... damn goverment puts regulations on everything don't they?
so... did anyone figure out how to get rid of our speed limiter?
ttufrosty
10-25-2006, 01:40 PM
Again, experiece from a previous car. My Old 03' Impala's governor was part of the ECU. You had to get one of them fancy expensive tools to read the ECU and the governor was tied to the type of tires you had on your car. From what I remember you could switch the ECU to the type of tire you want to raise or lower the governor. Not quite a chip, but a modificaiton to the ECU.

You can also contact JetChip (www.jetchip.com). They did a custom chip for my son's firebird. Gm has a replaceable ROM in the ECU. I don't know about Toyota. Jetchip does all kinds of custom stuff and if the ROM is not replaceable, they would either have or make a module.

I run the HKS SLD on my AE86 and it works great for factory ECU. I wasn't able to top out the Yaris last time out to the track, but came very close... it would hit around 110-115 on the back straight and stay above 100 mph for most of turn 8. You need to be on a very high speed track to reach those speeds with this car unless you have some big power under the hood :wink:

I occasionally drive my dads Avalon and it gets to 135mph very easy... once you pass 135mph its just another league everything feels strange :evil:
My yaris doesn't go further than 117mph on a straight (i have not tried it on a downhill:biggrin: ) And it its not really a pleasent feeling in such a small and light car. Maybe with an very good suspension and other things it could be good. I drive on 18'' and its a little better but still never safe

i believe it's illegal to remove the speed limiter. I think the point of having this in the car is to hopefully prevent excessive excessive speeding and at the same time allow police to be able to catch criminals or else their cars would keep going faster till the force of the air resistance held them at a constant speed.

Its hard to tell if the Yaris are limited and if thats the case at what speed because I have reach 117 and it doesn't go any faster but not because of a limiter its just because its a Yaris for fakes u can't ask more to the 106hp

when you hit a speed limiter, usually your motor will slow down
the yaris does not slow down at all, it continues at full power at that speed, this means the car is topped out and cant possibly go any faster because of the lack of power

I think speed limiters are for the tires more than anything else. I know that 2 of my pals both had the same model car. One had a special package that included powdercoated stock wheels and yellow lettered tires.
His speed limiter was actually lower than the other guy with the regular tires.

This is what your looking for. It will take your 118MPH limiter off. Make sure that tires can handle the speed, basic S class tires are only rated for 112MPH. I also heard a rumor that you can remove the limiter when you change the clutch:confused: probably just a rumor though. Q answered!

If you think going 85 MPH is insane, wait until you see what happens at 88 MPH.
:laughabove:
That said, I remember reading a while back that if you pull the e-brake one click (just enough to trigger the light but not enough to make contact with the drum) it would disable the governor. BUNCH OF LIES. D: My hatch fell flat on her face at 115 MPH, which was kind of frustrating, because it felt like she had enough gun to hit 125.
Tailwind? Not sure. I didn't check the weather conditions at the time. But she had life left in her. Looks like I'll have to look into the SLD once forced induction is factored into the equation.
By the way, a side note: a tire's speed rating is to show the maximum speed/friction the tire is capable of handling at max load at 100% constant speed. Short bursts above the rating are at your own risk, but I haven't had a failure yet. My 1987 Supra Turbo was wearing some kind of economy R-rated tire (106 MPH) and I had her up to 165 with no blowout... but again, and I can't stress this enough, it's at your own risk. But you SHOULDN'T have much of a problem if it's just a blast to top speed and then back down to 65 MPH.

Gee DarkYaris, didn't you know you were buying a speed limiter when you wrote Toyota Canada a cheque for your Yaris?
I've owned some cars that with 50/50 weighting that handled great - a BMW 3 series and an RX-8 to name a couple. But nothing handled the switchbacks or was funner to drive on winding mountain roads than my Yaris with simple DF210 springs, stock shocks/struts and some sticky 17s. Plus I could buy Red Bulls with the cash I saved at the pump on my road trip.
If you want to go that fast in a straight line, though, do something safer - like getting shot out of a cannon.

I'm with cali yaris on this one, my '87 Celica GT-S has a limiter on it also, and it's set for right around 124-126mph. The last time I had the Celica at Virginian International Raceway for a Track Event, could not get above 124 on the 5400ft. back straight. It was like hitting a wall, but would hold right at that speed. Speed limiters have been a fact of life for year due to Government regulations, the Insurance Industry has pushed for these things to protect us from ourselves, and to cover their asses from speed related fatalities. I have raced sportscars since the early 80s, if you want to call a '74 Honda Civic 1200 or a '84 Nissan Pulsar a sportscar, well there was the '84 Honda CRX Showroom Stock car, but they all made great track cars. Any car can be a great sportscar if properly built, and if used under the right circumstances, ie: not out in crowded city streets, just gotta use good judgement and learn your cars limits. Oh and by the way, even the little 1200 Civic would run 108mph with a drafting partner!!

I'm quite curious about if this actually works or not. And if it does, does it also throw off the speeometer?
If it does, maybe a call to JET should be in the works. Even if it costs hundreds, at least then you could probably use their power programmer to play with other things such as the rev limiter or throttle response, right?
SAV912
03-06-2011, 02:11 AM
The only real benefit for that would be throttle response, unless you have serious engine modifications like boost or some such. The DBW lag is helped tremendously with some aftermarket deals like that, but there's no real reason to get something that expensive solely to defeat a 118 MPH speed limiter.

Or CONVERSELY, allow more timing advance if you're running 91 high-octane.

There isn't one for the Yaris that can change either the rev or speed limiter.

So, as of right now noone can go pass 118 mph in this forum, kinda sad.

Cali can cause he is not using the factory ECU. He is on a AEM EMS....

I'm quite curious about if this actually works or not. And if it does, does it also throw off the speeometer?
If it does, maybe a call to JET should be in the works. Even if it costs hundreds, at least then you could probably use their power programmer to play with other things such as the rev limiter or throttle response, right?
I would be willing to throw down the 76 bucks to try it...if it didn't there would be no reason why someone couldn't just eBay it or CL it for @ least 50 bucks...

We just unplugged the speedo at the trans. :wink:

simply cut the wire going from the speedo to the ECU and you're free to speed away and you still have your working speedo. You will have a CEL though.

I made a device similar to the greddy one and it works for fooling the ECM to avoid the speed cut out (verified on the bench, not on the street). The speedometer value is incorrect once the limit is passed (it remains at the speed that I am feeding to the ECM), which in my case is 115 MPH.
I also made one for the rev limiter, but am afraid to test it on a live engine.

Yeah... Our dash uses GPS speed.:biggrin: But if you just want to do a top end run (on a closed course) it is a temporary solution - although if you unplug it for your top end run you better have another way to verify speed.

This is the exact same solution to the limiter issue on the early Celicas, in fact the wire is marked SPD on the ECU main plug!

If you set the rev limit to LESS than stock, you should be fine to test it.

That might be cool if you could turn it on and off with a toggle switch.

What is does is send a modified tach signal that indicates that the engine is spinning at a different speed than it really is. I am afraid to test it in either direction (telling it is is spinning faster or slower).

I really need another Crashy to be able to do potentially catastrophic testing on.

I would like to have the limiter disabled only for those times that I am taking it for official timeslips, etc once I have my turbo installed.

At what RPM does the stock rev limiter kick in? If it's anything like most FI factory systems, there is about a 200-500 RPM window above the point where it kicks in to safely rev the engine. Back in my Auto-X days, I raced a 1989 Civic Si, it's factory rev limiter kicked in around 7,000 RPM but the engine would free rev to around 7,200-7,400 and come back for more abuse!!
