Speed governer

Hey all, new to the forums. Just wondering on how to remove the speed gov. Does anyone know how?

yeah, i need to do that too with my mazda6.

Easy fix. Take out your PCM. Kidding. Speed governor fixed in pcm memory. How fast do you want to go? Have not taken a 3 or 6 up to speed yet but have had an 8 up to 148 mph before had to shut down due to upcoming traffic on the highway. 148 mph is plenty fast for me. How fast have you pushed your 3 or 6??

I've only been doing around 90/95. I dont wanna jam the acceleration cause i'm still breaking my car in. I'll unleash her around 2000 miles on her tranny. Then I wont have to worry about how long the road is.

Lol, well I really havent push my baby yet, but I heard that she shuts down at 120. Theres and ecu upgrade on http://corksport.com/tab0.4/store/category/5rpm/ate-engine.html Dont know if it takes the speed governor off though. And
Ive been 140 with my friend in an Acura Integra gs-r.

I also found this http://www.sfxperformance.com/parts/UNI1320021.htm for the ecu. But i still dont know if that overrides the speed
governor, I might try and e-mail both companys and ask. Just have to get my e-mail working.

140 quite a rush isn't it?!?!?! Can you imagine being behind the wheel of a top fuel drag car at the end of a 1/4 mile? I can't but would be a hell of a ride.

now that would be one hell of an experience

ive gotten my m3s up to 120mph on the highway...just wouldnt go anymore...but i got up to 150mph (scary fast!!!) in my pop's Mercedes E55 AMG! going that fast cars actually look like theyre driving towards you on the highway. that car puts anything to shame.

Lol, nice.

never gone that fast, but i topped out at 118mph in a 1996 ford explorer.... now that is scary as hell

Ha ha, ive also gone 108 in a Dodge durango(felt like i was going 40) and 120 in a volvo s40. Ran out of road for the volvo but the durango has a speed governor also.

ESPECIALLY in an Explorer.

yeah, my "X" was shaking real bad around 90-100mph, then she smoothed out again but roads in my area arent too long.... lots of bends. But I have never come close to rolling it or tipping it.

NOT AVAILABLE.... SORRY....PLUS ----->IS IT WORTH BLOWING THE MOTOR OR TRANSMISSION CAUSE YOU WANNA DRIVE 150MPH-WARRANTY WOULD BE VOID IN THAT CASE.

Thats a good question. Maybe

I posed this same question under General Tech titled "Removal of Top Speed Governors". From what I understand, it will void your warranty with any tampering with the computer. I've topped my out at 200kmh(125mph) and the governor kicks in and the speed drops to 160kmh(100mph). It's disappointing as there is so much more car.
One of my past cars was a newer BMW 3 series. It did not have a governor on it and I had the needle buried once, 240kmh+(150mph+) for an hour following a new Mustang Cobra. What a rush! Everything else after that seemed slow. 1400km(875mile) trip took just over 8 1/2 hrs with no tickets. Won't be doing that again anytime soon.

Thought they maybe only put a speed governor on US spec vehicles but looks like they have the same in Canada. I wonder if they have the same in Euro spec or other models? If someone is on from outside North American market will you let us know if you have any top speed restrictions built into your vehicle?? Might have to take above 120 mph or whatever kph that equates to but would be worth the test

Don't get too crazy on those stock Michilens I've had my old Miata at the rev-limiter in 5th gear around 135. My buddy in left me in his 300ZX doing well in excess of 150MPH. We opened them up on the interstate after work around 2:00AM. Slowing down to 70MPH afterwards felt like I was in a school zone. Last time I'll go that fast. Too much to lose these days.

Ok, jet has a chip for the 6, but dont know if they can change the speed gov. from that. Heres the site by the way. http://www.jetchip.com/products.asp?pid=14478&make=28&model=1114#1114

Ok ok ok. for all you speed freaks out there that like to go faster than 120 mph, heres your solution. http://cgi.ebay.com/Apexi-RSM-Rev-Speed-Meter-for-Turbo-NA-Nissan-Subaru_W0QQitemZ4586873085QQcategoryZ102557QQrdZ1QQcmdZViewItem It works for any car and it overides our speed governors. Have fun at the track

is it the same speed limiter on all models?

i havnt taken my 6 over 90

but i know on the 94 and 95 TA if you had the 8cyl, z rated tires from the factory, the obd1 computer and the obd2 connector: they skipped the speed limiter, all other 8 cyl from 93-02 with z rated tires got 164 mph speed limiters, and if you didnt have z rated tires they gave you a 118mph speed limiter.

just something to think about with so many different models of the same car floating around it could be different

i dont know how you or why you would want to do that unless you bought car strictly to race and dont need the warranty. I have on 06 3i, bought in september and taken to 100mph so far, had a 1990 chevy beretta and taken to 120 a couple of times, that is fun, but a little scary.

Hey,
I would like to know the same thing, but I don't know if mine has a governer. I don't want to find out the hard way and also I herd that my tires are only rated for 148 mph so they could blow if I got past that for too long. Even thought I have had my 2004 6s with 18,000 miles up to 150 mph for about 5 mins and it never shut down on me. That was one Hell of a rush I was racing a G6 on the interstate at like 4am. But lately the only racing I have done is my friends 2006 Acura RSX and I got him once but he won the other 2 times those things are quick as hell. I would like to see RSX, a 350 Z race because I have driven both of them, and they are both very fast. Has anyone tried the Nissan/ Subaru chip upgrade for the 6 yet?

The Mazda6 cuts out at 124 mph. If you went 150, someone already deactivated the governor.
