GMC SHUT DOWN AT 160KLMS
Question:
Hi; Does anyone know how to disconnect or eliminate the engine from shutting down at 106 kms on the newer vehicles. I have a 98 Z71 GMC. When you reach speeds of 160 kms the engine shuts down. thanks. email
Response:
Likely only by reprogramming the ECM or with a replacement PROM. Why in hell you want to exceed 160 km/h I don’t know. Your stock tires likely can’t handle that much speed – that’s why the limiter is there. — Robert Hancock Saskatoon, SK, Canada Home Page: http://www.geocities.com/TimesSquare/Arcade/9967/ – Hide quoted text — Show quoted text – >Hi; Does anyone know how to disconnect or eliminate the engine from shutting >down at 106 kms on the newer vehicles.

Response:
Surely you mean 160 MPH, not KPH. 160kph is just under a hundred miles an hour — even my Chevy Blazer will exceed this speed… Many cars sold in the U.S. have governors that prevent them from passing 155mph. However, I was able to very easily overcome this in a Mercedes 96 model. Good luck — check your facts and let me know what you find out. – Hide quoted text — Show quoted text – >Hi; Does anyone know how to disconnect or eliminate the engine from shutting >down at 106 kms on the newer vehicles.

Response:
The vehicles are limited to a speed of 100 mph max. I was following a long series of trucks and campers on a long 2 and 3 way road one day, and when I had the opportunity, I went for it, was gonna pass a bunch in a row (yea its not legal to pass more than one in Alabama) so I stepped on it, got it up there and all of a sudden at 100mph it sort shop it has a limiter that causes it to shut down at 100mph……. You can change the chip out, and rid the vehicle of this what I say is a serious factory builtin fault. foxeye – Hide quoted text — Show quoted text ->- >-Surely you mean 160 MPH, not KPH. 160kph is just under a hundred miles an >-hour — even my Chevy Blazer will exceed this speed… Many cars sold in >-the U.S. have governors that prevent them from passing 155mph.

Response:
This is not a factory built-in fault, but rather it is done on purpose. The reason why some vehicles are governed at certain speeds is the tires. My wife’s ‘94 Camaro had the governor set at 104mph. GM told me this was because the tires were only rated at 110mph, but if we had gotten the car with the high-end rubber, no governor limit would have been set. It’s a liability thing. For what it’s worth, check the max speed rating on the tires you have…. Have fun – Jonathan – Hide quoted text — Show quoted text – > The vehicles are limited to a speed of 100 mph max.

because you were too much of a know-it-all to realize that tires have limitations and that perhaps your choice would not be any better than what the factory put on. So go do your pissing and moaning elsewhere, either that or buy the high-speed-rated tires to begin with. Cause I’m tired of paying higher insurance rates so the company can settle with your wife and kids because of your arrogance and know-it-all attitude. Soapbox now available for others to use.

Let’s see…. You buy a vehicle with tires rated at 110mph, but frankly, who really looks at the tire data on the sidewall. On your way to your brother-in-law’s factory discount appliance outlet and tire barn for new rubber and rims, you crack the throttle wide open on a stretch of vacant interstate. At 140, the stock rubber gives way, sending you into an unrecoverable spin. A group of my brother (and sister 
) firefighters show up and scrapes you off the road with a putty knife and a shop vac, but hey – you’re still alive. After a week in ICU, 3 months in the hospital, and 5 years of rehab, you go to law school, become an attorney, and sue the car company because they didn’t protect you from, well, *you*. Hence and forever after, governor’s are put on all cars produced from that point on limiting the car to just below that of the rated speed of the tires that come on it. The good point about this story is that you weren’t the first guy to do this, someone else was. So now what you have to do is either spend the extra money for upgraded tires from the dealer (hence no governor because the car can’t go as fast as the tires are rated for) or buy a new chip for the ECM or whatever when you get new rubber from your brother-in-law.

The limiter govenor is for 2 reasons, Liability and to protect the engine. 1) Liability…Todays cars due to there aerodynamics are capable of well over 130+ MPH for something as small as a Grand Prix and the larger V-8 350 cid cars are capable of 160+. The stock production chassis is not engineered to take on those speeds and with some people and there mindset taking these cars to there limits we would see so many law suits to the makers of these cars it wouldnt be funny. After all the cops need to catch you somehow right? Look at some of the Mercedies and BMW’s that are in europe. There are no limiters however these cars are much more refined over there than in the US. We would rather have a soft loafy riding Camaro (general populas speaks) than a rock riding Camaro. People are spoiled lets face it. I spent almost a grand to get my cadillac deville as refined as I could. Skidpads of almost 0.80G and still keep my ride. Will automakers spend that extra on the car? I dont see it happening. 2) Engine…Take your rear axle ratio, final drive ratio of the transmission and circumfrence of your tires and figure out what the engine speeds will be… Take a tire P255-60-R15 60MPH= about 915 RPM 915 x 3.23:1 axle ratio = 2955 RPM engine At 120 MPH this would be double… Now take the overdrive ratio of the transmission (0.70 typical) and make your final drive ratio from there. 3.23:1- 0.70 OD= 2.53:1 2.53:1 x 915RPM= 2315 RPM shaft double that for 120… Im sure you get the idea there. Taking something like a pick-up truck to 120 MPH or even over is absurdly stupid. They are for hauling loads at 65 not 120 let alone 150 MPH If you want to drive at those speeds with a truck please let me know so I can make sure my son and myself are tucked away in the house as it doesnt take much of a twitch to send it sailing out of control…
Response:
Hi Guys: Thanks for all the input. I didn’t mean to open a can of worms and get people peed off at each other,,,, but that’s the beauty of free speech.. The truck in question is actually my brothers and he lives in an area where traffic is not heavy at times. The problem he has is like one other guy mentioned is that he’ll be passing someone and the engine will die on him. I told him about the speed rating of the tires and he laugh at me saying, he has drove for 30 years and has only had on tire blow out at high speed and everything was ok. I not saying this is a smart thing to do ,it’s just that you should be able to decide when to take your foot of the accelerator. I guess the problem or topic here is that vehicles can be outfitted so people cannot exceed a predetermined speed, which offers some protection to my family coming down the highway when this vehicle is going faster than 160kms. I have a 1991 GMC with a 350 in it and I have Michelin tires on it and have had it up around 160 to 180 klms and it feels like the dam thing is not going to quite. I taking my changes doing this and knowing I could kill myself or worst kill someone else… You see, it’s not your life people worry about if you want to go that fast on public highways,, its their own and their family members that are with them!!!! If a drunk driver drives down the highway and kill your family, the point about drinking and driving soon hits home, , The same is true here, If some bone head come speeding down the highway at 160 to 180kmh and kills your family you would probably be lobbying to get limiters installed in every vehicle.. I never liked being told I can do this or can’t do that,, but I released something one day, that when your actions effect other people then certain limitations have to be imposed to keep all of society in line or safe.. i.e.: If I choose to smoke a cigarette on my property its no one else’s business, but when in public I start affecting people around me, then laws have to deciede what is best for all. If I choose to drink at home, that’s my business but in public I have to behave myself or the cops will take care of me. I don’t agree with seat belts because I’m affecting only myself, but the law says I have to wear them. So, there is different ways to look at these situations.. Bottom line we all have to live together and really try to protect one another in our daily lives while we make choices. I love going fast sometimes, but what a price to pay if your family looses you in the process, or someone else.. Well something to think about… Chuck.

Chuck, The examples you cited here are true Freedom of Choice issues, but there is a misconception if you believe that they only affect you. If you smoke cigarettes and get lung cancer but can’t afford to pay for your chemotherapy, or if you drink your liver into a stupor and can’t afford a transplant, or if you drive without a seatbelt and get into an accident and can’t afford your own medical bills, guess who pays for all that stuff in the long run. One of the major points in the recent tobacco settlements with the state’s govenrments is that they were attempting to recoup money spent for medical treatment for smokers who couldn’t pay for it themselves. Additionally, I doubt if anyone is going to truthfully say "Let me die. I enjoyed 30 years of excessive smoking/drinking/whatever and I deserve what I get." I think even the most diehard will eventually say "Help me" when they are staring into the face of an early demise, and We, The People eventually do (maybe not always or always well, but some things do get done). I’m not by a far piece saying that everything the government or big business does to protect us (like speed governer’s, etc.) are done because they are humanitarians (actually more often done to protect themselves – from litigation), but the excuse of "It’s only affecting me" is too often untrue to a very large extent. If you believe in Chaos Theory, then everything that happens, no matter how small, somehow affects everything else. It’s all a matter of degree.

It definitely is a product liability thing generated by the current legal atmosphere we are in. Light trks typically quit about 100, some cars go to about 105, Z-28s with the opt tire & axle pkg have not limits as to Corvettes and genuine police vehicles. Pontiac GTPs and Intrigues with the Autobahn Package (Goodyear RS-A "H" speed rated tires) stop at 127mph. Buick doen’s use RS-As on the Regal GS with same eng as GTP so it’ll quit at the lower speds just like a reg Regal. You may be able to reprogram the computer (no chips in current production) to get around the speed limiter, but you have to know the codes. I contacted HyperTech a few years agot for an export customer on getting the speed limiter out. A rep told me they would do it on a custom basis providing the customer brought the vehicle to them, paid the money, and signed a liability relase. They later disavowed any knowledge of this conversation. You may feel this is an infringement on your rights as an American citizen and you may be correct, but GM in NOT the only manufacturer doing this. Enjoy to the maximum extent of your tolerance level — at your own risk and hopefully not my risk! Now really, just how many times do you really drive past 90 mph? I like to as much as anyone else under the right conditions. But, maybe a little more finesse and prior planning might be in order to plan your driving moves instead of just "going for it" and hoping you can make what you want to happen happen. Play like you’re driving a diesel when you’re not.

Response:
Yes, A very leagle issue. They cannot let the car go faster than the sustained speed rating of the tires on it. And, it semms these tires only go on the vehicle with the sportier suspensions. i.e. Cadillac Seville SLS is limited at a lower speed than the STS. Todd
