If you see 99.9%'s in the 100% column it is a bug in the software (I know, I know, FTECU bad, Whoolich good.)

I guess I pulled the Power 1 EB 1 table. Your Power 1 EB 3 is relatively concave. As for the rest, why leave them like that?



I still think folks are missing the engineering logic behind the tables being shaped the way they are (and this includes HRC ECU fuel tables) - it is based on the feedback from the Honda test riders that the bike is faster if you only feed in the throttle needed for maximum acceleration versus dumping 100% throttle then trying to recover from wheelspin to regain forward movement.

The FTECU tables are the same crap numbers FT seems to shove into all tables for all bikes with Fly By Wire throttles.

That 100% across the board indicates a fundamental misunderstanding of the presence of Electronic Throttle Valve actuation.
What possible value is 100% throttle at 3000rpm in 3rd gear with 190rwhp on tap?

I am only setting the bike up to my personal preference as I prefer the more traditional no electronics progressive cabled throttle. I just bought the new one because it fit me better, it's lighter, and I got a hell of a deal on it. It has the added benefit of being able to tame the low load throttle valves settings so it can be as calm as a 250 if I want. Will it go around a track faster with stock like throttle valve settings? Maybe, but I prefer a more analog feel. If I demand 100% throttle, I want to have it now. My philosophy is "get the bike to make as much power as it can everywhere and it's my job to learn how to use it". Different strokes and all that, I guess. As for Honda's "total control" propaganda, I think they neutered the bike for noise emissions and gave us a half baked bike with a lot left on the table in terms of power. Every refresh is a few mouse clicks away from "5 MORE HP for this year!" to keep sales up. You know as well as I do what this bike is capable of when de-restricted. I completely see where you're coming from. I just do it different. PS: How do you get the graph to look like that?

Fair enough, but lets be practical and honest here - how many people have been riding 185rwhp 420lb cable throttle controlled analog street bikes over the last 20 years?

I never said it was a good idea, it's just REALLY fun! It's a challenge to master it, but once I do, I can ride anything with no dependency on electronic nannies. Oh, and I'm working on getting a solid whp number as soon as the shop can schedule me in for a dyno day. If it works out with the E85 I might go back and do a few runs on 93 to get an apples to apples comparison for you. I'm still not sure how much of a problem that front wheel speed sensor is going to be. Might have to rig up something to read a signal off the rear tire as if it is the front tire.

You will probably need to do this if you are not going to use Woolich software to disable the front wheel speed sensor error signal.

This is how the HRC ECU equipped bikes are dynoed. You need to get a wheel speed signal off the rear wheel. As for the Stock ECU bike, not sure that will give the proper results as there is no calibration. On the HRC ECU you set the front and rear wheel size the same and jump on the dyno.
