Duty cycle on fuel injectors for tuned bikes

[Prof J]

Any of you with flashed bikes know what is your max fuel injector duty cycle at WOT top RPM?

[Prof J]

David,

In the various tunes you do fo the H2SX, some of those tunes, I'm wondering if any of those tunes get into the 90's percentile for the fuel injector?

On the M109, maxing out the CFM, in the 700+ CFM range, the injectors were in the low 90's. So if any other mods were gong to contribute to increased air charge, it'd be a good idea to swap out to a higher performing set of injectors.

sorry, just saw this

you have to tag me if you want me to see something


the software does not have injector duty cycle in the it, but if we assume that a value of 10000 would be a duty cyle of 1 even with the full systems and sprint filter we are around 30% near redline at full throttle

The stock tuning is so rich at full throttle for the stock bike that even with a full exhaust I am removing large amounts of fuel from the stock tune, so at most RPM (including at redline) the duty cycle is less than stock

Hey, thanks. I was not expecting that. Stock maps must be fat, indeed!
