ok. i can see the point at 15 minutes idle.

But isn't better before doing that to unplag the battery for at least 1 minute? Somes ECUs reset, by this procedure.

Also is it possible to confirm that 390 has a BOSCH ME17.9.8 TC1762 KTM ecu unit?

How meny seconds are needed battery off for reset?

Final question? how much more inlet flow can handle the
BOSCH ME17.9.8 withoot changing the open loop afr values?

Final question:

how much is the stock open loop AFR ratio? I believe it would be about 13.5: 1, but i haven't tested with a wideband lambda. If there is anyone that has tested it, please answer.

Finally got around to trying this after 2500 miles. Frankly, I was a bit skeptical, but it has made a difference. Less jerking around at low rpms and I can carry each gear about 5 mph lower without the engine protesting. Until and/or unless I do any mods (exhaust, airbox, etc) this seems to have done the trick. If it doesn't stick permanently as some have reported, I don't see any big inconvenience in having to repeat it periodically. However, since apparently big brother is out to get the aftermarket, I may have to buy an exhaust and ECU piggyback just in case!

yes, the 15 minute idle seams to help especially after small modifications. And in order to answer my questions, after installing the Κ&Ν air filter and after the 15 minute idle process, i haven't noticed any change in the AFR values at open loop. This means that the stock ECU can manage small mods such as exhaust or air filter replacement (in my opinion not both), if the 15 minutes idle procedure is made after the installation.

I have done the reset like 4 times (twice 2015 and twice 2016) and the effect is null. The bike is the same with no improvement or perceptible change.

I did it because low fuel economy. The problem appears every winter and disappear entering in the hot season so now it doesn't worry me anymore.

That 15 min idle reset is in my experience useless and i believe that many of you are just feeling the placebo effect.

That's what i can say after 10.000.
