Alrighty! Here it comes!
So to start, I want to thank Todd for his impeccable customer support. The problem I had (see above) was resolved within minutes and Todd sent me the revised map within half an hour of when I've sent him the stock one! Your customer care Todd is next to none! Appreciate the assistance very much!
Now to the tool. Took about 12 minutes to download the stock map onto the tool and about 7-8 minutes to upload the revised map along with TPS and auto-learn resets. Nothing difficult or very involving in this process. Pretty much a plug and play, just like everybody likes it.
This morning, after uploading the map onto ECU, I've embarked on my "or so much fun every time" commute to work. Immediately you feel like you are on a different bike. If not for all the great little, and some not so little, noises the little Guzzi makes, I would think I've switched to a different motorcycle. The throttle is so smooth, I couldn't believe it, but I see myself getting used to it very fast and believe that the bikes should come this smooth from the factory. But they, most likely, have their reasons for making it the way it is. Power delivery is smooth and constant, I can now cruise in first gear and low rpms (NYC rush hour problems) in traffic, as suppose to the previously experienced jerkiness and throttle lag in those conditions. No dead spots during acceleration - priceless! The pipes have become quieter, still can't believe it's possible, but almost no backfires (definitely no shotgun pops) and the popping on deceleration has decreased as well. Still get some, but I can live with what I have after upgrade as suppose to gunfire I've had before. The bike seems to be running a lot cooler too. I accidentally touched the pipes when I arrived and didn't burn myself, so I had to touch them again to make sure I wasn't dreaming. Even the shifting has become a lot smoother! I don't have the "try to shift into first" or "let's how fast you can find neutral" problems first 10 minutes after the cold start.
All in all - I'm really happy with this upgrade and would definitely recommend it to anyone who has issues or dislikes the throttle response and power delivery of the stock bike.
Thanks to Todd and the rest, and happy riding to you all!
