This is more for Goldwingmann. You asked what could be different between the tunes?
1. This R is basically played out for some riders. Other riders think they can't take any more power and think the factory should stop is criminal if not out and out BS for the limited type, 'man has go to know his ____ Fill in the blank" riders that think in those terms. You've met your limit on the modding. Soon, this mod will make you want more power, but now you are saying this is enough. NOLTT is you'll be on the same page soon.
2. Brock has showed on the dyno about losing 3hp or 2hp up top if the bike is tampered with. Brock also stated he would sacrifice that for the bottom grunt in exchange. WATThat did was change the speed of the sub's opening. That is one part of flashing.
3. Note I said, I said that the subs moved faster. There is your bottom end feel. Note I said, I said that each tuner can only set the ECU to an either/or. Either the ECU stays under your seat and you have a slow, liner moving sub, OR, your ECU comes back with the subs moving faster is the flash all 3 are handcuffed to. So no flash is different. It is more like what to select in the 'either/or' way the computer limps.
4. Either you have 2hp at the top or you lost 2hp is the limp of the flash. The bottom is the speed event of the sub change. The bike can run like that forever because it is more redundant to keep working in an either/or kind of switching.
5. The flash mod, if you have all of the OR's toggled, it still means the pig and pipe keep bringing more HP gain, let alone the 2 you lost. The maps are nothing more than setting a certain amount of fat feeding: to make the bike pound smoother. That's what you are feeling. So if you could see the Ivan AFR line vs. a Brock AFR line, those are feed bag lines is how the bike is fed throughout the rpm range.
6. We should be here on the same page thinking: every flash is the same is the given. Every map made is different. We now see 2 different animals playing with the tuning game. Ivan is more the 'driveability king,' whereas Brock would be the 'king of stock.' Brock gets all he can out of the bike without cam timing or porting, right? Ivan is just a map tuner or brass changer back in the day. So both tune different, both are handcuffed to the same flash.
Make sense?
