Let me know how it goes. I did this on my last bike and it was transformative. I'm just looking for smoother power delivery (and a few extra hp is never bad!). I had a drop in MPGs, but it was substantially due to my right hand. After I got over the perks, I started to ride more sanely and my mileage was nearly the same as before, but without the annoyances. Worth it.
It's nearly impossible, let alone an issue. I've flashed two over the years. Zero issues. There are no smog-check requirements for registration, so no opportunity for an inspection.
I've noticed a very small drop in MPG - ONLY after I got over the initial excitement of the smoother delivery and more power throughout the entire RPM range. On my V-Strom 1K I got between 5-10% less mpgs overall, even though I still dipped into it more often than before the flash.
Well, this time of year fuel mileage will drop. Cooler weather and winter formula fuel. I've lost .6mpg since October.
I’m interested to learn what map changes were made to the S map as opposed to the T map. I assume that the S map is tuned for more power and torque and smoother throttle response but what is the T map tuned for?
I had my ECU flashed by 2WDW this month. For me, the most noticeable improvements occurred in T-Mode. I was expecting S-Mode to be night and day different (which is vastly improved), but I wasn't anticipating T-Mode to become so much more useable. To me, T-Mode now has a slightly stronger throttle response, but it is still muted compared to S-Mode at partial throttle. I would say it's much more linear than it was stock. I also installed a full exhaust just before the flash and only have 800 miles on my ST, so I don't have much experience with the ST before the exhaust and flash.
Oh wow, I only paid $250 for my flash. It showed it was "on sale" when I bought my flash the first week of January.
The modes kept to their intended purposes, they are both more usable now, though - for me - the T mode is a bit too soft for in-town riding, especially off-idle. But when locked in on cc, it's about perfect. The S mode is more usable overall, and I've been keeping there for commuting.
Same, I factored in the outgoing 2-day postage, about $15.
I seemed to have hit it at a good time, but even at $300 this mod can't be touched for the overall gains.
I suspect all your bikes and cars are perfect..Glad my bike came perfect from the factory.
Or maybe my expectations aren't very high.
'Cuz, I don't even notice most of what people are complaining about on the Tenere.
If you haven't figured it out yet then look at my "What TenereGUY has been up to " thread. Pics and all in there.
To be fair... my 50 L panniers are a lot more wind resistance and I was loaded way to heavy... but I always had what any one person needed! With panniers off, only my 270# plus gear on the bike and at 63 mph I am right around 49 to 50 mpg. Just letting people know so they can make a more informed decision.
