Stock ECM learning curve?

[mrdozer2you]

Does the ECM need to re-learn its map everytime I ride? It seems as it would due to changes in weather conditions, temperature especially. I really noticed this the other night. The first few times I had my bike out I did some decent riding, but nothing with extended periods over 3500rpm....at least not enough for my ECM to re-calibrate. I did some throttle cracking and it seemed like it had less power. Now I went on a real long ride the other night with a friend....we did 15-20miles on the expressway ( ECM re-calibrated? ) When I got off the express way I cracked the throttle in 1st, the front end came up no problem and overall the bike felt like it had significantly (maybe 10%?) more power than normal ME LIKEY!!!! Now how do I get the bike to run like this all the time? I mean, every freakin time I ride do I have to go for a 10mile trip on the expressway to get it to perform as it should? I took it out the next day after my night of fun and it was back to havin less power. Couldnt get it up in 1st...just generally crap [sad] Now it was maybe 10-15F higher the next day than the night before...would this be making that much difference?

Funny enough I have found this same situation.. i thought i was just nuts.. or the bike was loading up.. then when i'd hit the freeway 70+ for a few miles it would liven right back up again, so i experimented with riding around town for 10 minutes or so, and sure enough back to the same old lazy power.. interesting.. wonder if the race ecm, k&n filter, and a new pipe would cure that?

Anyone out there? I'm admittedly a complete ******* when dealing with buells and am lost after working with KTM's, and Asian bikes for so long.. WOULDNT GO BACK FOR THE WORLD THOUGH!!!

oh yeah mines an 07 uly but imaging an xb12 bike may have this behavior?

Sweet!! i'm not alone.... or nuts

well...ahm...[smirk]

aslong as you're keeping the bike at a constant rpm, with very soft acceleration, it should be in 'closed loop'.
which would mean that the ecm will learn from that loop. but since there was no reset, the loop will not be saved?!
just a guess, but seems logical...

clue is to always give your bike a good & nice warm-up ride before hitting the throttle.
for best perfomance, the bike needs to reach the best working temperature.

aslong as you're keeping the bike at a constant rpm,

I thought it had to be above 3500? For a certain length of time?

Its hard to do that where I ride unless you hit an expressway. There are loads of cars and stop lights making it almost impossible to maintain a constant rpm for any lenght of time.

So it doesent matter if I have to stop, as long as I accelerate slowly? Thats contradictory to what i've been reading here. I'll give it a shot and see how she goes.

 

[LeFox]

best is no stops...but if you have too, slow acceleration and don't go above 3000rpm

 

[mrdozer2you]

slow acceleration and don't go above 3000rpm

again...contradictory to what everyone says....they all say keep rpm's ABOVE 3500. Im so confused.

I rode yesterday after letting my bike warm up for a while. It was around 70F. I rode with slow acceleration and didnt exceed 3500RPM except maybe 1 mile on the highway. Didnt really notice any difference in performance like I did the other night after 40min of highway riding.

 

[LeFox]

above 3500rpm? for learn in period???

the fact that you are experiencing better performance after longer high rides is because the engine and its oil is in optimal condition.
it's not cause your ecm learns on every ride...it learns after a reset, yes.
