I had my gen 1 flashed a few years ago. It still has a 2000 rpm surge that I hate. However it is easier to ride and I would do it again.
A More Affordable Flash Option?

holligl,
Modified "S" mode it is ... I've been getting 'used' to the S mode for the past 500 miles and I'm liking it more & more. Though I am still bit 'abrutpt' with my wrist...sometimes me and sometimes irregularities on the road that changes my input. I'm starting to think why we needs '2 fuel maps; T & S'. I feel with smooth input + better fueling map, the 'modified S' reflash can be used both on/off roads. I mean, we have multi-level TC too IF we get carried away with our input...hmmmm.

Canadian owner here. 2018. I have 9000 miles on my bike (15000km) and the twitchy throttle is not only bothersome but almost dangerous when maneuvering slowly in a parking lot for example. I am very aware of it and even being a seasoned rider, it is my only dislike with the ST. (My other bikes were HD's and I converted last year.)
Being Canadian I don't think there is an easy fix. I have read the horror stories however if there are any suggestions to help remedy this for a Canadian bike, please let me know....and it's not about calibrating my wrist. 90% of my riding has been in T mode as well.

Avalanche 123, I would suggest you install the Booster Plug. It is a simple plug-in device that tricks the ECU into thinking its much colder outside thus richening the fuel mixture. Please see their claims on their website. I can only speak for the CA 2017 model I own but it made a significant difference in smoothing out the running of my S10. I amazed more S10 owners continue to discuss flashing their ECU's when this plug in device works very well.

Again, you have a bike from California, the birth place of all the emissions control lol. I will look into it but....I am skeptical it will work with a Canadian bike.... Thx!
I installed a 'booster plug' on my 2016 FZ-1 which made some improvement on the throttle response, but it drastically affected my fuel economy. It was so bad, that I un-installed it couple of weeks later. Maybe I had a defective 'B-Plug' or just very sensitive fuel map on my bike ...
kmasa58,
I have 6,000 miles on my S10 since installing the Booster Plug and have been averaging 47 mpg.
Avalanche 123,
Read their website, they have a money back guarantee. The symptoms you mention could indicate a lean fuel mixture.

I did check out their website. I agree it looks like it will work. My local dealer is a friend of mine so I am going to ask him for his opinion and possible fixes. I have no issues purchasing a Booster Plug but I'll need to know if it affects warranty etc.
The Booster Plug installs between the airbox and ECU, simple plug-in. I checked with several dealers in my area and none of them had a clue for the occasional stalling and jerky performance of my S10. I had adjusted the R. TB to 3/4 turns out and did a TB balance which helped a little. The dealer said if they worked on it they would have to adjust it back to the original setting. I was desperate for a fix. At 1,000 miles I installed the Booster Plug and it greatly improved the machine. Effect warrantee, I'm sure a re-flash may do that. I wish you well on finding a cure for your machines performance issues.

Thanks Riley, It looks to be a little "gimmicky". OTOH, it is fully reversible. And not a bad price. The only issue I have with my bike is once in a while I stall it when letting out the clutch from a stop. I figured it's just from poor clutch use on my part.
And seeing you are from Orange County, you have the smogged CA model like me. One thing that's noted on the website is the ambient temperature showing on the gauge is going to show 35 deg colder than it actually is on your dashboard display. No biggie. You can just remove it from the display options and put something else there.
Problem with the re-flash is you are stuck with it once it's done. IMO the very best way to get performance is take to be dyno tuned. But that is some big bucks.
Yes, does sound "gimmicky" but the principle is sound. I liked the idea of a plug in installation that was easily reversible, not too expensive, and supported with a money back guarantee (though that doesn't help a lot since it comes from Denmark).
Dyno tune yes if you have a very competent tuner with the capability of reprogramming the ECU. I would be interested to hear feedback from other Gen 2 S10 owners who have tried the Booster Plug. When I first purchased my S10 I was looking for a fix for the occasional stalling, jerky throttle response and lean fuel symptoms and I found someone posting on the forum about their positive experience with the Booster Plug and decided to give it a try. I would add that my S10 engine was very tight when first delivered and it performs much better now with over 7,500 miles on the odometer.
I have 2015 ES and have had a booster plug installed for almost 3 years. It is hard to remember what it was like pre booster plug... but I do like the way my bike runs. Basically, it seems to enrich the fuel mixture at lower rpms. And I am still happy with my fuel mileage. At moderate relaxed riding during the summer , I average better than 20 km/l. The booster plug fools the bike into thinking that the ambient air temperature is 20 deg C less.

Have you removed as much slack from the throttle cable as possible? This really helps people control the throttle more evenly.

No I haven’t but it’s worth looking into. I talked to my Dealer today and they said I could try the Booster Plug and if any warranty work was required, they would reset to stock so warranty wasn’t affected. Interestingly Yamaha doesn’t have the ability to tune that ECU. They just do diagnostics for codes. As a previous HD only, if u didn’t want to dump, u could buy canned maps. Too bad that’s not available from Yamaha.

HD and KTM seem to be some of the few that do factory firmware changes or different maps.
Be aware that the Yamaha spec for throttle play is... excessive, by many rider's standards. A previous dealer used to be so proud of themselves for 'correcting' my throttle play when I had them do the valve adjustments. And then I would have to take the slack out again. It's easy to do. Just slide the rubber cover off the cable and loosen the lock nuts, play with it until you are happy, snug down the lock nuts again.
Note that the slack changes a little when the bike is running, Vs when it's off, so what feels perfect off, may be a little too tight when the bike is running and may impact idle speed. Swing the bars lock to lock to make sure the idle stays the same.

Where some guys don't like the engine braking, I love it!! I can see where in a deep sand wash the sport mode can be used to control slowing with just the throttle without touching the brakes. For those that don't understand or know how to use the engine braking, I can see where they would want to get a reflash. I OTOH embrace the engine braking and use it to my advantage.

I LOVE the engine brake. I use it to my advantage.... going into a sharp corner a little fast all I have to do is let off for a second and I'm right back on the throttle. For me and my style of riding it's perfect. I'm coming off a detuned RSV so the S10 is amazing...

Believe it or not some guys do take it in deep sand. I followed a guy though the pine barrens my first time off road I buried my V Strom past the calipers he just blew right through it on an S10. Took me 4.5 years but I've got mine now.

I have a Booster Plug fitted to 08 Fireblade, which were known for being a bit twitchy from just on to off . It has helped a lot when doing low speed manoeuvres, tight downhill hairpins etc and the fuel consumption has not changed either.
For me the S10 (18 model) is fine, yes the throttle is sensitive but compared to a lighter bike with more power ie the Blade, it works very well.
I think if I was coming from a slower and heavier bike the S10's throttle would feel twitchy and would fit a Booster Plug with a softer throttle cam as mentioned above.

Shame you haven't tried a Gen II with Chris Stillman's dyno-developed flash. Huge increase in performance for just 199 quid.
