just a comment about the governor

SentraE · Oct 9th, 2003, 12:23 AM

ok i understand that on my car and motor the governor is set at 109mph. well on my car ive hit 120mph befor it kicked in. my speedometer is i guess right cause ive driven past those roadside radars and i stay at a certain speed (like 40mph for ex.) and the radar says im doing 40mph. now i make sure im the only car on the road. could it go out a little at a little higher bit higher speed (like maybe 90 and higher or something) i dont know maybe my governor is set a lil higher or something?

yeah i have hit 110 AND 112 BEFORE. and then it kiks me back down to 109 and makes me go down to 105 slowly but stays there... i have a 93 4dr sentra E

thought this thread was about Arnold.....haha

Your speedo isn't accurate at that speed and other variables...ie tire size...etc... the ecu cuts fuel at 109... period

OddyseusDSM · Oct 9th, 2003, 09:52 AM

i've registered 123 mph on mine when my fuel cut hit. scared the hell outta me, till i figured out what it was. anyway where does fourth end? 124? i have almost hit redline in fourth (varified my friend in passenger seat) and the speed varified by a friend in a '94 Honda Civic Dx. i'll dig up my tranny program and put in some ratios.

dah, how does the ecu know when the car's actually doin 109 when the speedometer can't tell accurately?

The speedometer IS accurate at low speeds and then starts to fudge it at higher speeds due to a combination of tire size, wheel slip, and other blah blah blah...

The car takes whatever your speedometer reading is... compares it to your RPMs... takes an average... and then dumps it...

I've had my car in various states of trim over the past few months...

when I had a working speedometer, the car would cut me at what seemed to be 112 mph (on the the speedometer).

when I had my defective speedometer, it would cut me off whenever my speedometer read OVER 109 mph (even if I was only going 60)...

when I finally disconnected the defective little f*ck, the car would accelerate all the way to 5000++ in top gear, or 6500 in third gear, and then the fuel cut would kick in around there... because according to the computer, if you're at xxxx rpm in x gear, you're probably going 109mph or more...

the ECU knows how fast your going through a vehical speed sensor. apparently this is independant of the speedometer, i myself have not varified this, but i'll bet someone on here has.

so how do u restrict the governor. like bunch of those honda kids' in mah town. dont have governer's, just few of my frinds that have acuras and hondas.

How do you restrict the governor? Two choices:

1) Get a reprogram from JWT
2) Get one of those speed-limiter remover boxes.

SLOW SEDAN · Oct 17th, 2003, 01:19 PM

where can u get a speed-limiter remover box

According to my speedo I've done 131 going down hill on interstate 285 bypassing atlanta. Mine didn't limit the speed. My entire car died and I had to start it back up again after I coasted to 100 (according to the speedo). I am still running the stock wheels and tires. Could there be something wrong with my speedo or ecu ? My speed was also verified by my fried in his SOHC Del Sol (he stopped at 115, I think), and a CRX.

sentrasersr20de · Oct 19th, 2003, 03:21 AM

doing 131mph down the interstate. Isn't that drving wrecklessly, illegally and possibly killing some one other than yourself? That's kinda like illegal street racing which is frowned upon on this web site.

Opinions are like assholes every ones got one. This was mine

StevenLK · Oct 19th, 2003, 03:33 AM

what does it actually do when u say tha fuel cuts'.... my gas petal is floord' and about to snap and then the mph keeps droping and i feel a deep drag. but it still going over 90'

SentraE · Oct 19th, 2003, 04:28 PM

lol.....last night i ran it again to see if maybe the speedometer would actually register 109 at the cut out and the needle still hit 120 but this time a left the pedal at the floor and when it cut back in it jerked th wheel so hard i went in to the next lane thankfully there were no other cars on the bridge (exept for an integra that i passed and he tried to catch back up but couldn't

) it was scary for a brief second but its all good.

StevenLK · Oct 19th, 2003, 04:53 PM

yeah i ran last nite. and had a firend in tha kar and then saw trooper lights and pulld over thinkin i was gonna get a $100 ticket. and having a heart attack and with such relief it passed me!!!!! omg lol , but so when the fuel cuts off it brings u down of turn off the kar?... and is it bad for u kar. kause this one crx last week was racing and the middle of the 2nd run [best 2 out of 3] his car ran out of gass.. haha and he just coasted down and we race in the highway by a gasstation and. they sed his engine messd up .. just the piston ring or sum thing kause i dont kare... but it doesnt do harm to the engine relly does it when the fuel cuts kik in...
