Default Does the SERT learn?

Do any of you tuners know if the SERT can "learn" and improve the tune.
The first time I ran the 124 up to 5000 it had a real hesitation and the exhaust sounded lean. Torque was real strong to about 4800 and then seemed to tail off. I am running the canned S&S 124 program and still running in. Anyhow, I have run her to 5k+ a few times and she seems to be getting better, torque seems to rise about 5200 now. Maybe its just psychological??

Popular question...

Your ECM learns, there is a feature called Adaptive Fuel Control, the values are stored in memory of the ECM and allow for adjustments to AFR. These values over time create develop a correction profile that is applied to your AFR. I beleive these adjustments are marginal, I have read ~10% but I don't stand by that number.

I don't think these marginal changes are great enough to really notice but its hard to say as I don't know how much adaptive Fuel control can 'correct' your profile.

The SERT/SEST isnt' still attached to you bike so doesn't provide any further corrections it is a tuning devise

The only 2 "autotune" sytems are the thundermax and PC-V with the auto tune module they utilize wide band sensors

If you have a closed loop bike, yes, it can learn. I'll send you a PM.

The closed loop system operates in a narrow window, mostly under cruise conditions. under hard loads and over 30-40% throttle the bike is in open loop and runs on a predetermined map.
