2017 RSV4 Akra slipon + custom fuel/ignition SSTK Race map by Gabro

[Gabro]

Did last week my first 2017. It's a fast bike!
Tested both full std, euro4 compliant, than with Akra slipon + std race map, than i've built my custon SSTK map over it.
It's the final results, euro4 bike VS full prepped!
(red linea are rear wheel power, black are power at the clutch, blue is torque)

nice graph!
Is it possoble to do a dynograph in 2nd gear to see the difference in "the problem area"?

 

[Gabro]

It's very hard doing any dyno test is 2nd gear.. rear tire will slip!
anyway, now the ex-valve is removed, but motor still shows a dip in torque at about 4500rpm

Hi Gabro,
Great work. How would the mapping and performance change if instead of an Akra slip on you would use an Akra evo ll complete exhaust system.

Thanks for the answer

Not yet tested in 2017 bikes, but in 2015-2016 bikes does not change a lot... fueling does differs that much: complete Akra system just add 2-3hp's up top, and 3-5hp less in the 6000rpm zone.

Gabro, thanks for the fast reply. When will you have a mapping for the Model 2017 with a complete Akra Evo II, race air filter and other sstk modification ready for sale?

 

[Gabro]

it is ready.. as i already told you full system VS std headers in 2015+ bikes create very little differences in fueling. That can't be addressed from a mailing map flash
2015+ stoch header system is an "industrialized" copy of the Akra EVO2
