Are you calling all the members that have posted their speed BEFORE YOU EVEN GOT HERE liars???
And what is "Most evidence in this thread would seem to back that up" what evidence???
No photos, no wiring diagram, no pin out, no mention in HONDA'S own repair manual, no system description. I'm mean come on they get down to repairing the ASHTRAY in the repair manual wouldn't they logically have to show Honda mechanics how to repair the mythical speed limiter?????? give it up there is no evidence

What I meant was there are two pictures that show <115mph speeds. There are none that show anything over 115. There are claims which may or may not be true. Like I said, anytime I see evidence of someone going faster than 115 I'll admit I'm wrong. You could probably do 117 or 118 down a hill even, but I doubt the car can do 120 or higher.
'Course I'd love for someone to prove me wrong.

Pretty much every new car these days comes with some sort of speed governor. Hell, I even remember my friends '95 200sx SE-R cutting out at 109mph, once OBDII was the standard. My '91 SE-R however could hit 140 easily with mods, and hit 14.8 @ 94mph at the strip too.

Sorry, I forgot that how much someone knows about anything is directly proportional to how long they've been registered on a forum. Shit.

Course your AVOIDING THE QUESTION where are your wiring diagrams, pin outs, system description ETC. anything.... no really.... anything beyond the photos????? NOPE
And there is a photo right here in FitFreak showing 120mph. If you had been around long enough to read the post you might have seen it.

i may be wrong, but isnt there a rev limiter? and wouldnt it give the impression that there is a top speed limiter if you hit the rev limiter in 5th gear? again, that was a question. not stating fact.

Of course there's a rev limiter. You can even hit it while revving the engine in neutral.

Can anyone get the source code for the ECU software?

Rpm limiter would bounce some cylinders BUT in 5th gear at 120mph you are not at the RPM limit. 4 th gear maybe
And for Mr. cheapo some good thinking there but you wouldn't even need the tachometer signal because we are "supposedly" limiting vehicle speed not engine RPM so all you need for input is the signal from the VSS (your Speedo signal).

gee...you people sure like to fight...especially fit over lame shit like this.
for those of you who think fit has a speed limiter. You have made your point clear, unless you have more new and constructive input, just chill out.
for those of you who disagree, go over 115 and take a picture.

Movie quote--From a Dirty Harry movie, and correct me if I'm wrong, but I think it's Magnum Force.
Anyway, as far as defeating governors, I don't know for sure, but I remember reading articles about companies like Superchips that make inline plug and play override units. The car that comes to mind is the old 240SX. One company made a unit that plugged into the ports on the computer, and basically recalibrated the data going in, so the speed recorded was cut in half going into the computer, which doubled the mph number that the speed limiter cuts in. So basically, the limiter wouldn't come on until the 240 SX reached over 200 mph---something it obviously couldn't do in stock form.
I don't know how companies currently do this, or if any still out there do, but the concept seems sound. Trick the Fit's computer so the limiter won't come on until 230 mph.

I agree with you on how the governor can be defeated. I used to have a 944Turbo. It didn't have a governor but part of the package I put into it had to raise the Redline 2000rpm. It accomplished this and some other things by reprogramming the two eproms in the computer.

If the US Fit has a governor on it, I think that would be the first ever Honda to be sold here with a governor. Drag and engine power are the limiting factors here. Obviously, a tailwind helps the drag issue, and hills help power.
I wouldn't be surprised if the Fit is in the 115-120mph range. My old '89 CRX Si (almost identical HP, though a smaller car) went easily past 125.

most hondas have limits... most are around the 140 range
its fun to test the limits of your car. that's what motorsports are all about. testig the limits of your vehicle.

I know this is second hand information, but my father in-law just retired as the Marysville, OH senior plant supervisor (some title like that...he ran the plant). He has driven EVERY Honda currently made (and a couple that will be released soon) at the Honda prooving grounds. According to him, ALL Honda's have a factory limiter that is based more on the factory supplied tires than anything else.
The limiter is in the program in the ecu. When the limit is reached the ecu shuts the throttle body.

Whatever - I doubt I'll ever be testing it personally.

they could have had something like kpro to shut off the limiter. Shutting the throttle body does not sound correct but im not sure with the new DBW cars, with wire driven cars it would cut the fuel to the motor like you were hitting rev limiter
