ECU re-flash
I also had Anthony re-flash my ECU and am very happy with the result.
Other than mounting a GPS, it is the first mod I have done and one of the best in turns of return on investment. I have had many bikes, over the years, and have much experience with power commanders and jet kits. This is by far the most effective adjustment to motorcycle fueling of the bunch.
I went fairly conservative with my flash choices, choosing T-mode "light" and S-mode "enhanced". There is an obvious difference between them and a significant difference from the stock modes. Stock, I found myself running the engine up to 5k all the time, in an effort to "get up to speed". With the new flash, I find I can shift at 3.5k rpm and get the same result. Maybe even better as I like the throttle response and the 1:1 ramp up of the S-mode "enhanced".
The off idle flat spot, or what ever you want to call it, that occurred every time I let out the clutch is eliminated, which was the one thing I wanted the re-flash to address. That it did so makes the expense more than justified in my eyes.
With only @ 300 miles since the re-flash I really haven't taken an accurate look at fuel consumption but it does not seem to have affected it in a negative way.
I would HIGHLY recommend this modification to anyone who is not happy with the fueling, performance of a pre-2014 S-10.
