Read my EBay rider feedback for further feedback, I have said this a few time to you now not sure what else I can say, there are improvements over any map installed in the ECU because no one has altered anything in the closed loop mapping, there are improvements over the Flash Tune maps, STD 2014 map, 2014 reflash map, 2015 maps, so in all there are improvements over every map ever designed for this MT09 out there to date, not much more I can say.

Kev's "Anti throttle surge mod"!
- Thread starter mtmarcel
- Start date
I "should" have Kevs mod on the way as I've sent payment and I'll also be getting the Yamaha flash done in the next couple of months so I'll post the results unless someone beats me to it between now and then.

Same here,but just to ad,
Yamaha's re'map does make it better but they are governed by the emissions laws so they cant go the full hog.
Kevs does and addresses all the probs but obviously breaks the emission laws.
Its up to you,i also have a few old 2 stroke bikes and i hate to think how they would go on with the tests these days lol
Thanks for the pointer, I will look into the Ebay feedbacks, to see if anyone specifies doing it on a Yamaha flashed MT09.
I apologize for sounding so anal, and repetitive, and appreciate you patience in answering my questions.
I really love this bike and have since the first day. With every modification (G2, suspension, remapping...) I'm pleasantly surprised that I like it even more. That's why I'm willing to spend even more money, in order to have even more fun on the bike.
I do realize that on the paper your mod does something that isn't addressed by any of the other maps, I'd just trying my best to make sure (without actually riding a modded bike) that it is actually noticeable (by regular human rider) and not just a minute change that can be recorded by a computer, before I fork out the money.
I'll read around the subject a bit more, and then make a decision. Thanks.
This is exactly why I'm happy paying for Kevs mod, I don't care about emissions.

Couldnt agree more mate
All them green do gooders flying alover the world to have meetings about pollution.
more emissions than all our bikes together in a lifetime.
TBH I'm not too concerned about the emissions either. I'm just concerned about spending money on something that may not make a noticeable difference (besides pissing off some green do gooders

Yeah I hear that totally. For me at least the surging while at constant throttle is really annoying, and from what I gather this is due to the air fuel ratio being cocked about with by the ECU. The effect may well be reduced by the Yamaha flash but as they are bound by emissions laws it'll never be completely solved, so hoping Kevs mod will help with that.

So if we are allowed a A/F ratio of 13.4:1 in closed loop why cant the open loop be the same? 
My bike is like a two stroke hunting and its getting worse....need a flash tune soon but gonna wait.
Graves motorsport flash tune hmmmmmm

I'm in the same situation as you (standard map-not reflash/stock exhaust) and i found that by putting a DNA filter the mixture (air/fuel) is reacher in low rpm than when i had the stock air-filter. The result is a less "snatchy" response about 20-30% than with stock filter only with that simple "modification" and that is noticeable on the road.
And for that reason i suggest it to all of us..
Sorry, but just now i realize that you have Arrow zorst... allthough i think that dna filter could help in your case...

Mine arrived today 
Unfortunately I've got a much needed engine strip under way on another bike and one of my storage spaces for the parts is the floor space under and around the '09,
so the O2 plug in won't be plugged in just yet

Well this thing definitely plants some candles firmly into the cake's icing.
The slight but never the less distracting hesitation that was still present on my 2014 ABS model after the Yamaha remap has now completely disappeared,
which leaves me free to concentrate on the more important things
Now did somebody mention about removing the top speed restriction in 5th and 6th gears?
