WOW 187 HP!!!! ) )

Hmmm, I sense Paul may be skeptical, just a guess though.

BTW, my very stock bike will wheelie on throttle in second gear (TC off) so the fact that bikes running the jumper will do this doesn't really mean much. I do like the way the bike runs off idle with the jumper in, seems to be a definite improvement there.

What are we jumping here anyway? Does the bike fuel as if the clutch is pulled in with this mod?

Has anyone checked for error codes? Maybe the thing just goes into a default mode.

Well if that is the case then it's a great feeling in the "default" limp home mode or what ever. And no I have not even thought of looking for a code.

I honestly can't see this harming anything except maybe using more fuel which does not bother me. My average is still 42 and change and I have run the piss out of this big slug. I cannot really feel anymore power through the range but the off idle feel is enough for me to keep the fuse in. I literally hate this thing in traffic otherwise. bucking, jerking, surging forward with almost no throttle input, all that was driving me nuts. Fused it just acts like a good running fueled engine should be acting.

Seems like it. I get the feeling that the EPA or [insert department of choice] doesn't check compliance using "default mode". I hope they don't read this forum then

This whole thread sounds like one big joke! I read all 6 pages waiting for everyone to fess up they we have all been duped, then make me feel like a big dumb ass because I actually started to believe it!

You guys are nuts! ???


oh yeah, then I was letting the dogs out and there was the bike, oh and there is a fuse. Oh WTF, ya got me. Yes, I put the fuse in......

I hope to ride a wheelie all the way to work tomorrow morning ::26:: I'm seriously skeptical (if you couldnt tell) I'll report back tomorrow....

Look if this was a science forum we would all have to show the theory, show results to prove the theory, prove the method of operation to confirm that theory and then have all the data peer reviewed and confirmed. We would also have to do double blind trials and show the stats.

At least we are doing double blind trials

Being one of the biggest skeptics, it seemed too good to be true. However I am a cheap bastard and this mod is a cheap bastards dream come true. I've road it for 2 days ~ 100 miles commuting etc. And removed the jumper this afternoon. Maybe I really don't live in Arkansas but near Jonestown Guyana, but there is a substantial difference in the bottom end particularly in take off's. 15 more horsepower, I don't think so. But 1st gear feels "right" and not too high. But still I would like to see the Easter Bunny and taste the Egg.

Tried it today to work. City commute with some 80KPH. Don't like it. Feels like S mode but like a light switch just off idle. I suspect it it some sort of test mode. I don't thing there's more power than in S mode, just more abrupt. ::007::

In the service manual it says you get Fault code 42 and diagnostic code d:21 if the switch becomes open or shorted permanently. It clears when the condition is corrected. The bike remains drivable according to the manual.

The fact the bike remains drivable should be a good sign. At least Yam do not seem too concerned that any damage is being done?

I will have another go with the fuse this weekend on my camping trip and see how it goes. I may even get some comparative dyno runs done if I get the time, but I am not expecting any top end gains as it feels like just a better response lower down.

The GiPRO gear indicator requires that the clutch be engaged for it to register. I expected it would not work, but low and behold it does work with the fuse in. Now I'm scratching my head how it knows that the clutch is engaged. Oh well.

Fault code 42? mmmm, must be The Answer....

I think the Gipro only looks at RPM and speed and if the ratio fits a gear, it indicates that gear - if it falls outside the lookup table, it indicates nothing, that is why it seems like it "sees" the clutch, as the clutch causes values outside the lookup table

As an example, if you slip the clutch a bit in say 3rd, it could indicate 2nd, as the RPM/speed ratio seems like 2nd gear

That explains it!

Got it!!

My thoughts as I have run it this week back and forth to work. Same roads same speeds. almost.

The clutch bypass is just taking away the dampening in the throttle. Since S and T mode are no longer active we now have a Super S mode. Direct throttle control without any dampening by the ECU. When the switch is active (no jumper) , as you would let out the clutch and begin to roll out the switch would engage the dampening would kick in and you would get the stumble.

Switch bypass as you give it throttle there is no dampening and the bike respose to your command and not the ECU.. Super S mode.

No changes in air/Fuel ratios . If I drive normal and easy my fuel comsumption is the same as if the switch is not jumped. If I enjoy the response I get in jumper mode (Super S) Then my fuel consumtion goes up.

With the jumper in your Sport and Touring mode is disabled because that controls the dampening of the throttle response. Jumped there is direct throttle control thus more WOW.

Some may not like it as, Yes this puppy puts out a lot of Power Now!

TC is still active so as long as you leave TC in 1 or 2 you are OK. Take TC off and you very easily can break the rear loose and or shot for the sky.

Drive easy and fuel MPG are the same. But it is so hard to do.

 

[Dingo]

With the jumper in, is there a difference in response between T mode and S mode? If yes, I think I would tend to agree with you that it is lifting the throttle damping, as opposed to being some new 'hyperspace' map.

BTW - the ECU provides the air/fuel combination based on input from sensors (e.g crankshaft position sensor tells the ECU how fast the engine is turning, where TDC is and what position the crank is in, while the throttle position sensor and MAP sensor indicate load). How the sensor information is intercepted by the ECU depends on the type of mapping.

 

[mingo]

So has anyone determined if this free mod nets the same result as an ecu reflash?

Would you like some cyanide with that whine? Sorry ^-^ couldn't resist ...

 

[JaimeV]

I must try it!! ::012::

 

[RMac]

You seriously are a bunch of cheap, desperate fucks. Still haven't tried it myself cos I have the flash already. Might be a really interesting combo to try...matter of time, priorities and blah, blah ....
