Not really, the cam profile and layout of the motor is past its output RPM. You might choose to bump the software up 100 or so RPM's but depending on weight, bags, shield, wind, Etc you might or might not see a top speed difference...fedev2 said:
I have the ECU-U Gen2 Flash - but will shortly be getting it replaced.
Like all flashes the restrictions are removed, makes a good difference to low-mid range pull 1st - 3rd (40mph in third gear gains a whopping 25% more power)
It also alters the S-Mode throttle response and IMO is too aggressive making the bike a bit snatchy if trying to ride hard in lower gears (for example on Alpine Passes)
Overall it is worth the money on a stock bike, but they cannot get the fuelling correct for Arrow Headers - an issue for most Flashes, and most vendors recommend a Power Commander to get this setup correctly.
Other flashes are cheaper and probably do a similar job.
When I get my new setup sorted I will post results, hopefully also get before and after dyno curves of ECU-U Vs the CJS Flash.

I have the gen 2 flash from ecu unleashed also, and I was only using sport mode out on the open highway. I always used touring mode at slower speeds because throttle was so jerkey and hard to modulate.
Then I got one of these G3 throttle tamers and it made a huge difference. I can use sport mode all the time, it really calmed the snatchiness for me. Anybody frustrated with this issue could try this fix, works good in my opinion.

Quite a few folks with the Arrow Headers (I call them the "tuners"), have combined the flash with the PCV and auto tune, and developed some maps (including Dyno time), and have pretty much created a "package".
I've seen and heard a few of them at Rallies. They do NOT sound or run like the average flashed OEM Tenere. Not everyone would feel it is worth the time, effort, money.......but I would go "full boat" before I'd give up on the Tenere based on power.

I've had the same jerky problems with the Gen 2 flash. Thanks for the info. I'll have a new throttle tamer on next week.motostevie said:I have the gen 2 flash from ecu unleashed also, and I was only using sport mode out on the open highway.

With a throttle tamer another issue may appear - as ECU-U leave the T-Mode alone it will become even more pathetic, so if you find T-Mode a little weedy once "tamed" it may become useless.
Another reason I am trying to get everything done with ECU Tuning alone, I can then have the throttle maps I want for both modes (Pretty much stock Yamaha S-Mode with an enhanced T-Mode) and perfect fueling for the bike with the Arrow headers - and all for less than the cost of a basic Power commander unit (not forgetting you still need to add the O2 optimization kit for the Power commander and flash the bike as well, and for perfect fueling have a dyno setup and / or autotune)
At UK prices if a custom flash can do everything for £400 ($600) it is a bargain as an ECU-U flash + Power Commander + O2 Optimisers + Fitting / Setup comes to around £1200 ($1800 :exclaim

Yes, this is true, It does feel like Tour mode is somewhat more pathetic, but it was nothing to talk about before the throttle tamer. I wouldn't say it's useless at all, but of course it's gonna be affected. Just have to twist a little harder and faster if needed. It's not a problem for me. Still works great if I need it in a tight situation or two up, but now I have the benefit of actually being able to enjoy the sport mode whenever I want!
I ride basically on the road only, and I have to say although I like everything else about this gen 2 flash, if I knew I could get similar results another way at the time, without this touchy throttle issue, I might have tried that. At this point one should probably review all their options, there seems to be more of them now. The G3 Tamer just works for me because I already have this flash.
To me, the ECU unleashed flash is great because for 400 something bucks, and no need for any other mods or $$, (beyond the G3 if you want it), it's probably imposible to get these power gains another way. or as easily. For me, it was extra easy because I got it done at a local performance shop here on Long Island. I dropped the ecu off in person one day, got it back the next day! Easiest, Fastest, and Cheapest big gain power mod I ever did. Of course all the others I did were on bikes with carbs, ahhh the good old days.
I was amazed how restricted the (2012) Tenere was. You are being ripped off, they are not giving you all that you paid for! (This is how I felt for a few seconds anyway). Whatever, but this truly opened it up to where you feel it's running like it should always have.
It has been said on here over and over, just do it! Get off the fence. It's as good as everyone says. The potential for more is stuck in there. Not sure why Yamaha didn't bring it out on the older Tenere's, but you can and should, with this flash or another maybe. I laughed at how clean and easy the whole process was. ::002:: ::022::

I have the ECUnleashed Gen II flash and don't feel it's too responsive at all. I absolutely LOVE how it LEAPS forward with the slightest twist of the wrist. I'm also running Arrow headers and added a PCV when I installed them. I think I could probably improve the map I've got but have yet to mess with it as it works pretty well.

Rasher, Have you seen the new Flash Tune harness that you can do your own tunes with? Sounds to me like that, a dyno, and a competent tuner person would solve your problems.
Nope, the Flash Tune Harness does not allow tuning of the closed loop area, I think a lot of the flash providers out there probably use this kit and that is why they tell people to fit a Power Commander if they have other modifications.Donk said:
As I said before even the UK ECU-U dealer tells me the bike is much better with a Power Commander added to the Flash. I think anyone who has had a flash and later fitted a power commander will be able to confirm the difference is significant - and a lot of that is probably down to the O2 optimisation that can be done with Power Commander kit to sort out the closed loop.
A dyno setup will also get a better result (Power Commander or Flash Tune) as it will allow everything to be perfected for that one bike. If you can go as far as mapping each cylinder separately as well that may also make a noticeable difference as just as no two engines are exactly the same, neither are any two cylinders.
OK, so now I can confirm the difference, I will post more info later, but today I had the bike at CJS, it was an eye opener seeing how complex these ECU's are, and it is easy to see why getting everything spot-on is so hard, but 6 hours later and the graphs almost speak for themselves:
Apparently the ECU- U Fuelling was not too bad, with the exception of the area where the bike surges with the Arrows....
...which is now 100% fixed, I can cruise at 2,000rpm in 2nd / 3rd without any surging, in fact it will drop right down to 1500rpm in third and runs smoothly and pulls away evenly - absolutely brilliant.
The bike also feels smoother and I am sure the tickover is less lumpy than before.
The O2 sensors are now off the bike and I just have the Arrow blanking plates in the sensor holes.
The Aggressive ECU-U S-Mode has been replaced by a linear throttle (1:1 mapping with full throttle available from 2500 rpm) Chris said I could have full throttle from tickover, but it would not give any gains and ham fisted throttle use in that region would be smoothed out the way he set it. This is actually very similar to Yamaha's 6th Gear S-Mode map.
T-Mode has been enhanced quite a bit by running the Stock 6th Geat T-Mode map, this now feels more useable, noticeably softer than the S-Mode I have, but without being pathetic as it was before - and it will give full power in every gear if you wrench the throttle enough. ::26::

I've never seen a Tenere dyno that high (or for that matter that low with Arrow headers regarding your 94 figure). Mine only reached about 99 with the Akra can, Arrow headers, PCV and reflash using a map developed by a highly respected Dutch tuner. Did they reflash your ECU with their own map? Sure would love to see your bike dynoed on another dynometer to see how it compares....Rasher said:
I have had it on a few dyno's and they do vary, so hard to tell:
Almost new it was about 86 in stock trim and about 92 with Arrow Headers (No other mods) on a local dynojet Dyno.
Race Engineering only did an after Dyno run when they applied the flash a few weeks later, they showed 99BHP on their Dynojet.
Nothing else had changed when I went to CJS Yesterday (apart from about 15,000 miles / 2 years) and they showed it at 94BHP to start with suggesting their dyno reads a shade lower. At the end of the day another 10BHP was showing - I was expecting the start reading to be higher and the end reading lower.
Will be interesting to see how other bikes read on his dyno, to be honest I am not bothered about putting mine on another dyno, I went there to try and get the fuelling with Arrows sorted and alter the Throttle maps and the result is what I wanted so for now no more playing, well maybe with the forks and I do fancy the 2014 clutch basket - but the engine is about right now and CJS did say I won't get much more without doing significant work.
The flash was done working directly with the ECU, it is all a bit beyond me, I thought there was "A Map" they adjusted for fuel and ignition, it turns out there are stacks of maps and it is not nearly as simple as I imagined.
I saw what looked like loads of Hex data they worked with, but they would occasionally bring up 3D views (like CAD software looks) and could manipulate the 3D image, they showed me some throttle maps in this 3D view and how they can bend them around.

Here's my chart before ECU tuning, just with a custom PCV tune.
Did you get them to check for any signs of restrictions in the lower gears on your 2014 :question: I know they are supposedly gone, but a run in the lower gears against 5th or top would have shown for sure.
And how much different did it feel afterwards :question:
As mine was fitted with Arrows and flashed two years ago I have no real idea how different my bike is to a stock bike, probably very different, may try and get a 2015 demo bike to try.
The other chap I know who had a CJS flash just had a "generic one" but described it as like a rocketship now - probably due to losing the restrictions in the lower gears which seems to put a smile on most peoples faces.
It will be interesting to see if he gets much more power from a bike with stock pipes, although he said even with the Arrows my bike still needed less fuel at the top end than the stock Yamaha map so they must be very rich on stock exhausts which would suggest there is a few BHP to be had on top of the restriction removal.
