Speed governer

I just found out last night that I apparently have a speed governer on my car. Why give me 140 on my speedometer, when I can only go 120?

question...

does adding an ems like micritech or the haltech for FI have any effect on the governor?

it will eliminate it
i hit 122 on my speedo,or at least thats what it read.could they have bumped the limiter higher for the 07 3's?
Not likely. Speedometers aren't exactly the most exact things on the planet. The ECU has a pretty correct speed reading (so long as at has been calibrated for the tires, supposing other then stock size have been installed), but the speedo might not show the correct speed.

highest ive gone is 165kph, i find on a decent windy day over 140 makes the car a little shaky, and it can drift a bit.
got mine up to 122(slight down hill )rt3w..but the gov kicked in at about 115-118..hard to say cause i wasnt watching the dash(dont stare at your dash when your doing 120)i did see what looked like a blue light on the needle tip but at that speed i couldnt really stare to see if it was lite up or just a reflection..
I was driving from Orange County to Palm Springs about a year ago and drove the car at max speed (~115mph) for a good 15 minutes. It was a Sunday morning around 6am on I-10. No cars in sight for the entire stretch. Pretty fun. Makes 80 seem like a crawl.
Yeah definitely fun... but it's also an awesome feeling to fly by other cars (few) going that fast while they're going the speed limit, makes you realize how fast you're REALLY going.
What happens when the governer kicks in? Do you just stop accelerating or can you hear the engine try to hold itself back?
it yells at you "Freakin retard, slow down!"

it just stops accelerating for 1 second then you can accel again.
not really much action at all.
I think the haltech fuel computer eliminates the speed limiter. Thats what the Haltech guys who've gone that fast say. I want to keep out of jail :D so I havent tried it myself.
I know what you mean siscim, I got that feeling abit passing people at 150kph, while they're going 110-120. a small difference, but its noticeable

There are blue led's if you look at the top of the guages right in front of them, thus the blue light
heh cant even do that in hawaii it sucks. if you go 115 and theres no cop around our the bends of our continuous turns then you are one lucky person.

Yeah, I'm sure it sucks living in hawaii ;)
I have hit 230km/h (143mph) in my 1/2006 SP23 manual Sedan. Its an Australian-spec Mazda, so maybe we don't get speed limiters in ours? Stock except for AEM CAI, Xforce exhaust and timing mod. Was just into the red zone in 5th gear ~6600rpm. 8)
Man, I'm glad I have a Speed!! :klavergreg:
Yea my 3 and my mom's miata are both governed to 118. At the risk of being yelled at by others on here, has anyone found a cheap way to get past the governor? Not a neccessary mod for me but it would mean more time to spend working on the car which is always fun. I'm actually going to school at an aerospace university in hopes of working on aerodynamics on race cars but I don't know the coeficcient of drag or other needed numbers to figure out how fast our cars could go if ungoverned
Its already been said how fast the cars would go stock if unregulated.
and just to cover it again. the gov does not do anything to ignition timing (at least pre 06) which is why the Haltech works. it's just a fuel computer, and since it bypasses the gov...means it's only fuel controlled.


and at this point....a standalone is an expensive way to bypass a gov that doesn't prove usefull enough to justify the cost.
