So I've seen the thread started a few times but never really seen an answer...has anyone figured out a way to bypas or extend the rev limiter past the measly 5250 its set to. Not interested in beating the 100MPH cut out but would love to get a few more revs out of this thing on the Dyno to see what else she has hiding in her shorts....say around 6000 or even 6500...if she's not hiding anything so be it and back down we come on the spin killer

The Fury isn't hiding anything. The max horsepower is at 4300 RPM and the max torque is at 3100. This is for a stock Fury and with some mods some things change, but not drastically. The max power for the extreme mods done on the Motorcycle USA Project Bike (2010 Honda Fury Project Bike Preview - Honda Cruiser Project Bike - Motorcycle USA) include substantial engine mods and the max power is still at 5100.

After you hit the max power RPMs the power tapers off and gives you LESS power. You could try to bypass the rev limiter but if you succeeded you would actually have less power by reving higher then finding the proper shift points. Also you risk blowing the motor up.

Here's the dyno chart.

Is their a way to bypass the 100mph cut out?

Yes, if you're an Electronics Tech/Engineer well versed in reprogramming CMOS chips, otherwise you're like the rest of us; SOL.

Cheers

Bike will become unstable and flop. Fuel management can not compensate. It is a chopper, cruiser, not a zoom, zoom.

I have seen many cruisers and choppers do well above 100mph thats y i was asking. Your positive that the fuel management couldnt compensate if reprogrammed correctly?

More than likely no, You would have to know how hondas speed limiter is restricted Some cut the ignition system to stop the engine from getting pushed harder, some cut fuel, and some cut both. Im also doubting you can easily bypass the revlimiter too

 

[BarFury]

Since its a digital control system, I'm thinking both routines (RPM and Speed) have to be responding to a COUNT per CLOCK algorithm, ending in IF-THEN-DO. As I said before, we just need somebody whose sharp at re-programming CMOS chips.

Just a second now

Okay so you mod the engine put max HP and TQ output 150 spins below where the rev limiter cuts it out right? 5100 you get to max then half a second later you fall on your face when you hit the spin killer. Now ask around and look at other performance charts out there for any type of competitive machine and see if you dont run at least 1000 rips past the hump. You cant enjoy any of that seat of the pants performance without extending it a little bit oh and don't forget we also got a speed limiter to deal with too. again like I said not worried about beating the speed killer, but when i kick her in the arse from the light or in a pack, i wanna be able to walk a little taller in the first 3 just like anybody with a performance machine does. Take a look at any dyno chart for just about anything and see if the redline and the top of the curve are the same.....they aren't. This ain't the first scoot with these "safety" additions for example most of the cows out there have speed and rev limiters but do a little research and see what you can do with 2 pieces of wire about an inch long (jumpers) and all the cows have ECU's too. Its not so much reprogramming the CMOS as it is figuring out how to fool it. Do some research its out there for almost all the other brands, so its hard for me to believe the great winged one from across the pond has come up with something so different from the rest of the world that it cant be done...think about it. Go buy a power commander that also controls the ignition and you will see a little tab up there that say "rev xtend" so its a click of the mouse, but if you look at those for these scoots born under the rising sun they have no ignition control, only fuel management.

Bike only has 3.5" trail! When it flops, and it is going to flop! RIP

This isn't a track bike, and this isn't a performance machine. But if you want to treat it as such it is your prerogative. Now, any track bike or racing machine for that matter, is designed to have max power at the top of the RPM band. But it is also set to get lots of power early and flatten the power curve to that there is consistent power through the revs. A V-Twin is designed to have mid range power and get power early in the revs. That is why the Ducatis have consistently been the best on the track. Mid-range power that runs through the turns.

A race rider, or driver, looks at the dyno chart and can see where the power band is and shift points are. To get maximum power out of any engine, a racer opens the throttle and shifts well before redline. Taking the motor to redline, or past it, robs the motor of power (as well as exceeds the viscosity of the oil, which can lead to thermal failure but that is another discussion). This you can see from the power curve dropping after max power is achieved. The trick to getting max power through each gear is to shift at the very top of the power band, not the maximum RPM. Making the bike rev higher then this point will actually defeat the purpose of achieving max power while riding because there is less power after this point.

As an example for a stock Fury, to get max power through each gear you would shift at 4300 RPM. Then the RPMs would drop to the middle of the power band and you would repeat the process for the next gear. If you've ever been on a true racing machine, you can feel the bike start to actually have less pull after the max power point has been reached. I've ridden Ducatis, R1s, Busas, and a Gigster or two. They all have less pull after max power has been reached and before the rev limiter.

I'm not saying that this motor can't be modded to have the power band exceed the rev limiter. But with the mods out right now, there is no need to extend the RPM limiter. As a matter of fact you will do more harm then good by doing it. But it is your bike and your money, so let me know at what RPM the bike actually blows up. I'm actually curious to find out.

 

[BluFury]

Very well said , totally agree .

 

[FuriousNateDawg]

Did you actually read my post? Did you actually read it all? Do you know that this motor will turn more than 5200 without issue? If you read what I wrote then you heard me say we are wanting to plan with some tuning and mod options but cant accurately test them without turning off the spin killer. If I needed a lesson on HP vs. RPM's I would have no business messing with the Dyno. Do you know much about valve trains and that they are the weakest point on the revs? Do you know the 1300 can spin to 6500 without, now there's the keyword, WITHOUT damage? Now I will say it again...I do not plan on staying above the limiter and dont want to and I again say I dont want to go over 100 but I would like to be able to makes some mods to the scoot that may and probably will need a FEW more revs. Theres not many mod options out there and guess why my friend...can't see around the corner any hey matter of fact you cant even see down the hall with the 5000 limit. I know its a cruiser and not a sportbike and dont need anyone else to make that oh so obvious statement, but maybe thats why the Harley riders laugh at the word Honda on this oh remind me again, cruiser. Let me say it again...not interested in breaking the 100mph barrier, but the next time you are stopped at a light surrounded by a couple 80inchers or a few sportsters, they look at you and laugh, then blister you leaving the light for a few gears, cause they were able to make some mods and someone done some experimenting with their type motor on a dyno somewhere, you'll be able to understand their laugh and more importantly you will learn how to read all the words in a post......expecially the title...you know that big word at the end of it ... Experiment! But thanks for the whole lesson there bud I needed to learn the differences between cruisers and tracksters and the like. I'll keep in mind that you aren't interested in any mods our little EXPERIMENT my produce since you are the guy that thinks the factory tune in compliance with EPA and gov regs is all any machine is capable of. Stock Rocks right? I just have a different definition of "Rocks" than you...I prefer the definition that has to do with "and Roll" as opposed to your use of the word "Rocks"----rocks like the rocks in the road huh? Keep on worrying about the kind of pegs and what type tassle to hang off the grips and what color to paint this or that spot and what kinda leather to park yor rump on and all those goodies and let the ones of us who wanna do some work on those parts that really matter do our thing.

Nate, there were two questions posted here, one on RPMs by you, power off the line, and a question by Dreamweaver, by passing the cutoff, both questions were being addresed here.

 

[FuriousNateDawg]

Glad you noticed that I only asked ONE question, but it irks me that you think it has been answered. It has yet to be answered anywhere on this forum in any of the threads that its been asked. The ONLY response to that question has been a basic "WHY?". Look at them.....so basically I have determined that the answer that shoulda been posted to the question was this..........No I don't know how to extend the rev limiter period. Never mind the why I asked just answer the question. Nobody out there knows what we are working on in our shop and on our Dyno. Everytime the question has been asked the answer has been why would you want to and a long tirrate about tuning theory and all like I need the education or asked for the education. I asked if anyone knows any software hack or wiring trick to bypass it....SIMPLE AS THAT! If you can not provide an answer to that question then read and move on, hit the reply button if you can provide answers not more questions and conjecture. Again key words remember the small details..."experiment" and "do you know how"

Nate:
We have not heard of anyone being able to bypass the rev limiter or hack the ECU.
The forum members would of heard if anyone has. To date we have not heard of anyone wiring around or bypassing it what so ever.
I hope that answers you question.

Notice I said addressed, not answered. However, life is not so simple, one question begets another. Without people pressing the limits, we never know what the limits are. I answered one question, speed cutoff, I am not qualified to answer your question, nor did I address it.

 

[FuriousNateDawg]

Thank you VERY MUCH! ALL take note....simple question...simple answer!! Thanks Tony! If I find one I'll be sure to let it be known since several others have asked same question and gotten no answer.

 

[FuriousNateDawg]

Hey Mental....isn't that what the whole biker thing is all about ????
PRESSING THE LIMITS!!!
I believe thats where real performance improvements come from too!
Thats what this WHOLE "Experiment" is about brother! so thanks for pointing out my point!

 

[mental]

Well, I am a little older, a little more mellow, a little more satisfied, I find the quicker I get off the line and get to where I want to go, I then still have to wait in another line! Such is life!
