How do you know it is lean?

It should be richer in those load ranges and rpm ranges. Are you saving the tune and reloading it? Or are you saying it is still lean in other ranges?

Sounds like you need to add more. What's your intake and exhaust set up?
The fact that it runs leaners with the O2 bypass connected further proves that Tuneboy doesn't completely turn off the O2 sensor. I wonder if it just diables the fault code caused by disconnecting it?

HiI dont know what I doing wrong.
I make decel mod(add %) in map 20219, full power, I2 I3 are same I4, plug the O2 sensor eliminator, uncheck the O2 sensor fited in TE, downlod the map to ECU, reset the adaptive settings and............the bike still very lean. Whit O2 checked or not , whit the sensor eliminator or not......the bike is very lean. I dont see any diference whi O2 or whitout O2 sensor. When I plug the O2 sensor eliminator the bike is more lean than whit O2 sensor on.
i have the shorty exhaust plus a kn filter fitted and have fitted the 02 sensor eliminator and fitted a wide band sensor in place of the original and it is connected to a a/f gauge so i can monitor any changes that i make when trying different tunes and i also see a weak condition on small throttle openings this as shown up in every tune i have tried(mid range and full bore no problems) so i have come to the conclusion that with my exhaust/filter set up i will have to put on a dyno to sort out .
i have also noticed with the shorty pipes that there is a big difference in exhaust gas pressure between the silencers the right pumps out a lot more than the other ?

This is weird. Wayne needs to 'splain this. In any case, at low throttle, we know it goes to the L tables for fuel. If you disconnect the O2 sensor and replace it with the PCIII O2 bypass, it simply doesn't use the measured O2 to calculate the gas. It should just use the L tables. Right?

Correct the L tables and whatever trims are saved in the ECU.
So it would be a good experiment for Habechian to continue to incrementally increase fuel in the relevant areas of the L tables until he gets some hesitation in throttle response and then back off. [Have you done that?] Maybe he doesn't know which areas are most important. Does he know that you can highlight cells and hit F8 (or one of those keys) to uniformly increment by a fixed percent?
