But don't worry about that. You can retune the spark later. Spark is tuned by knock retard events. I am keeping a linear progression of all my tuning so I can grab spark, VE, whatever from any tuning run. So say I start tuning VE in the non closed loop sections at run ten. I finish at run 12 and the timing map changed. I just go get the timing map from run 9 and import it back in to the new map.
Question: How do you tune the non-closed loop (i.e. out of narrow band detection areas) VE? I don't know what to adjust is there or by how much in which direction. As it is my understanding that the non-closed loop areas aren't picked up by the sensors and therefore aren't going to be corrected by the basic auto-tune. So that means it must be done by hand unless you are extending the closed loop range??? And are you extending it permanently or what? Forgive me... but I'm a noob when it comes to this stuff.

Under Fuel --> Fuel Air Ratio (Stoich) you set the cells that are not 14.6 to 14.6. This turns on closed loop operation. Then you do your tuning runs. If it was me I would do small portions of the non-closed loop section on any single run. The reason for this is the same reason Jamie has you retard timing, you are protecting the motor from going way lean in too much of the map.
EDIT: You have a 2011 bike that does lamda based fuel so the settings may be different. I have not looked at a 10 or 11 bike.

Are you certain that it is enabled? I enabled it on my tune but it didn't kick in until I did the throttle forward turn on for it. Then it worked just fine. I have it disabled right now...

Pass it's a different system on the 07s. I'm taking it back to the dealer to have it enabled on the digital technician because the switch in Vtune is not working properly. I want to get to the bottom of this because it would be really nice on the pre TBW bikes to be able to turn it on and off on the screen.

future instructions it would help if defined lambda or AFR. Even if they are the same and similar it creates confusion. With the other tuner that lets not mention any more same problem in their instructions. Waste of time wading through the CLB instruction when my bike is a 2010. Be nice if it was turn to page 5 if your bike is 08+

Has anyone been able to get the log tuner to work with a Lambda of .979? This is suppose to be Closed loop, but it shows zero hits with every log I create. If I bump Lambda up to .981 and run some additional logs, I get hits.. I went back and tried .979, and get nothing... This is in the range Jamie mentioned, not sure why its not working...
