First my mods
2015 R1
FTECU bike side flash kit with autoblipper (Graves Cat-Delete US map)
Graves 3/4 exhaust
93 octane
Sprint P08 air filter
520 chain conversion -1 front ---stock rear
Graves smog block off plates
Original dyno before chain conversion and filter upgrage was 181whp on a mobile dyno unit seeming accurate with a 2013 R1 full exhaust flash and filter doing 160 same day @72 degrees F
I now work at a shop with an in house dyno that generally reads approximately 10% low across the board on all bikes tested
Same tune with new air filter and chain conversion @ 50 degrees F (I know it's cold)
Produced 161whp showing fairly lean conditions on AFR from 14-15 throughout powerband
I then loaded the unrestricted map in and saw a 4whp gain and AFR more averaging 14 and sometimes dipping into upper 13
I proceeded to add fuel to the unrestricted map until my AFR was close to 13.1 throughout the entire powerband, but saw a slight decrease (.3) in top whp (165) and only gains in whp at between 9.5-11k rpm. Seeing that a 10% lower reading on our in house dyno compared to other dynos is the average... I can add approx 16 to this number to get starting 177whp with the graves tune and 182whp with the unrestricted(untouched) tune.
I tell this story to see if anyone has any experience tuning the 15'R1 and what they have used to gain more power, since adding fuel to get target AFR not only didn't gain, but actually slightly decreased in certain spots in the higher RPM range.
*** Unrestricted file is untouched shelf map-----*****Custom is richened to get the target at near 13 AFR------*****
