PCV Autotune F / L Maps?

Hi all

I have been looking around for some info on what the F vs L fuel tables differences are that I keep reading about are. I haven't had much luck yet in finding info as it keeps rejecting the short words in a search. Internet has also not yielded much either.

Could someone help me with some info or point me in the right direction to find some info. Am adding a PCV and autotune to a KTM 990 R.

Thanks in advance
Cheers
Rick

Don't bother with the auto tune. It doesn't work very well. Just have two maps for your PC V and switch them accordingly.

My experience with autotune has been exactly the opposite.
In any case, I wouldn't touch the stock ignition tables.

I was actually just about to start a little AutoTune thread here.
I've just thrown one on my bike, and wanted to share my experiences with the unit, as well as try to start a bit of a central location for info.
Found the same thing, there was really no solid information available about there, especially for the 990.

What I've found thus far regarding the F/L switch point.
With any "stock" F/L switching map, I've found AutoTune to attempt to lean these switching areas out, to the point of creating a worse and worse flat spot.

I've inputted the FL settings suggested by Tahoeracer last weekend, and have yet to see what the AutoTune has done.

Will report back.

Exactly. Its a very crude tool and nobody who i know in the dyno tuning world uses it. You are better off taking the money for the auto tune and have a reputable shop dyno the bike and have a great map.

Have YOU ever used it?
Dyno "pro's" will of course speak against it, they loose money because of it.

Thanks for the replies but have already bought the autotune so will be giving it a shot. Could anybody clarify the difference between F and L tables and how to set the switching? Or possibly have a link to some info somewhere.
Thanks
Rick
