What I mean to say is that with the fuse in place, (CJM) there is no difference between the T and S mode that I can feel (that option seems to have been eliminated). With the CJM I have complete control of throttle response instead of the ECU’s programed throttle response. The bike is now just as quick or slow responding as I want it to be, whereas before it was too slow on the T mode and too jerky on the S mode.

I don’t think there is any real power gain, just smoother and better control, which for me makes it a much nicer motorcycle.

I tested cjm mod both on and off road and I'm positive there's distinctive difference between S and T modes
S instant throttle response with great torque from bottom of rev range, no stamble only linear power gain, I use it most of the time because it's more fun
T less sensitive throttle and lower torque at low revs better suited for off roading and bumper to bumper traffic
Mid to high revs both T and S modes feel the same.
After cjm and Co adjustments (+15 both) motorcycle is so much better that I don't feel the need for reflash anymore I only wish tc2 was default traction setting.
Gas mileage is the same if not better, 43mpg average during my last 1300 miles trip wit 50/50 on and off road and 80mph average highway speed.

DOES the re-flash affect the gas mileage??

Mine has gone up a solid 3 - 4 MPG since the flash. Bike is well broken in now approaching 9K miles, very similar in that regard to my FJRs.

I have an V2 2014 ST.

I rode my friend's V1 2012 with a CJM. We compared both bikes with the S and T modes and the 2012 with the Super S mode (CJM engaged).

The difference is still there.

While I find that the 2014 version has a more powerful delivering on the first gears vs the 2012, both on the S mode, once activated, the CJM makes the 2012 more crispy and powerful than the 2014.

I wonder what news do we have about hacking the V2 of the ST.

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 Since S and T mode are no longer active we now have a Super S mode.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.

Hi No More Bills

Do you have maybe pictures to illustrate this - pics of the mod itself?

Thanx

 

[NoMorBills]

Wow,, thats and old post. But still holds true. As far as the Mod. Go back to the beginning it is simple just put a jumper wire or fuse as most have into the plug that goes into the clutch switch under the left control cluster.

 

[JMLUSA1]

Buwahahahahahaha!!!!!! Its causing Madness!!! and Delusion!!!!!

I thought the same thing until I tried the jump. Now, post jump, I can't keep the front end down on this big Yamaha beast. It paws at the sky like some nitrous fueled KTM on meth. In fact, post jump, I own R1s in the straights. The ladies know what's what. They hear this jumped beast coming and they start fronting, stripping out of their clothes lickity split to show me all of those naughty lady bits. It's just the nature of this jumped beast. Too bad for you - the jump is greater than the flash!

 

[grouseridge]

This simple mod gives great throttle response, glad it was here to read.
Thanks

 

[JMLUSA1]

OK Yep! It's true! CJM engaged (3 amp mini Fuse) Definately feels more responsive! That's My First Mod Too! ::012:: ::26::

 

[Juan Valderrama]

Next question is, have someone already done the CJM in the V2?

 

[Bushyar15]

I'm going to apologize now if I missed it in the thread. I tried to scan/read as much as I could, but didn't readily see an answer…

How does mode affect off road capability with regard to say super bumpy, loose rock sections where throttle control is very important? Meaning small throttle changes are required… Does the throttle in low gears become an on/off switch?

Is this better as an on-road mod?

 

[JMLUSA1]

Thats a great question Bushyar, I can tell throttle response is Pretty crisp! I havnt taken mine off road yet but im looking forward to finding out the answer to this for myself. :-D

 

[Bushyar15]

Just got back from a quick hour long ride to check this mod out and my new Corbin seat… Its my usual "Check out" section; Country Road, maintained to some degree, some wash board, sand and some loose dirt… No climbs/descents rocks, ruts, etc…

Okay, Seat-of-the-pants dyno didn't feel any "power (torque)" differences, gains or otherwise. I only ride in "S" mode so didn't bother to check "T".

I did notice that low rpm power delivery seemed to be a bit smoother and more linear. Not night and day different though. It also handled the "on/off" throttle position better at very low RPMs, better, not so abrupt.

Again, I didn't feel there was anything huge to b gained by doing this. I'll keep it on for now and see how it works in the rough stuff!

 

[tubebender]

I tried this a long time ago. Didn't like it 'cause something felt off.

Then Flash Tune cracked the ECU and people could see what was going on.

Based on the timing map - not something I'd recommend. YMMV

 

[Bushyar15]

WOW as soon as I was done reading, I went in the garage and pulled the fuse… That thing should be a sticky or something thats referenced. THANKS for linking it!

[JMLUSA1]

Ok Yes!!! I road around for about two tank fills and read this and pulled the Fuse out! Definately Feels more "Right" w/o the CJM. I can feel the ECU adjusting the Map as I go through the gears. Hard acceleration feels less "harsh" on the engine. So now Im looking forward to "Re-Flashing" but need a Tuner Shop with an in house "Dyno", preferably in Texas! Riding Sans CJM until then!

Digging this thread back up, cus I just wanted to express my delight with this mod. Put a mini fuse in yesterday n went out for a raz, but the rain n cold greasy roads kept me from properly getting a feel for any possible improvement, so put the bike to bed till today.., with the knowledge from this quick spin that things did feel different/better... Been a different weather story today with plenty of sun n drying roads... One word.., Wow! Awesome 5p mod is all I can say. Never red lined or full throttled it, but didn't need to, to feel the good stuff. The off idle lag on set off has gone and it now seamlessly n effortlessly revs in the first 3 gears. Feels really clean, crisp n lively. Non of the delay then catapult forward feel from stock. Brilliant! My mate did the same on his S10 and hes singing its praise too. Very noticeable to us. One thing, my next step is the Flash Tune remap now I've sampled the s10's potential .., but can't for the life of me imagine how much better it can get?? Read loads on here about the fuse mod n ecu flashing with everyone it seems saying a flash is basically night n day better than the fuse jobbie... Read on here, one chap say, stock he'd give the delivery/motor 5 outta 10, fuse mod 7 n the ecu flash '12' outta 10... ??? What gives? How is a flash supposedly that much better than the fuse on the road? Would love to know for now till, I finally send my ECU away to be given the Voodoo treatment...
Oh n what would we do without forums... ::008::

Simple. It's because of the ECU control maps for the relation between throttle and power output that each gives you access to. AVC8130 did my reflash and it is absolutely the way the bike should be and is that much better than the jumper mod.

 

[Rasher]

I went from Jumper to ECU-U flash and the flash is at least the same improvement again - and without the worry your engine could be harmed over a long term of CJM running.

I'm the opposite of mechanical minded, but am I about right to say, (in my simplyfied way) the ECU flash will be busy optomising 'each individual gear' to its best potential unlike a jumper fuse?

I've seen your enthusiasm for the flash on here and on another forum... Actually, before I took the plunge for the flash I was going to inbox (bother) you n ask for bits of advice on a few matters which I'm not sure of... All pleasing to my ears, this bigging up the flash. The Tenere keeps on getting better... Exciting times to come!
