2012 ZX-10R Stock w/ a slip on, bike drops -42hp & -25tq around 11500rpm when the 2ndaries start closing. Swapped in a Guhls reflashed ECU same day no other changes bike made the same power up to about 10500rpm then thats when the guhls reflash only made +8hp over stock until 11500rpm but then drops -31hp & -20tq around 11500rpm and it almost looks as if the 2ndaries are still closing. Granted when the butterflies are still closing its still making more power closed (or closed less) over stock +17 more HP over stuck when they close but there is still a significant dip in power still. Why does this do this?
I dynod in power mode F and traction off. I also swapped in a BMC air filter as my stock one was very dirty and only picked up +1.4hp. A/F are pretty solid in the 12.5-13.0 range. Probably will go leaner on the street due to air cramming in box.
I dynod the bike in F, M and L mode. F &M mode make the same exact power just changes the rev limiter back down to stock and the L mode makes a significant amount of power less to the point I didnt even want to finish making the pull it was so bad but was down about -43hp.
These are my findings. Hopefully someone has an answer to this. Id like to keep the bike pulling to revlimiter. I see dyno sheets out there with the reflash pulling to redline but mine doesnt. Mods to my bike are no cat, slip on, filter.
Ignore power numbers as this is a loaded dyno, not an inertia dyno)
