Hmm...that's really weird.
You might try this...
Using the Power Commander Software, advance your Target AFR table to be gear dependant. In the software, go to Map Tools>Advance/Demote Map. Then click the box next to "Target AFR tables" and select "Gear Advanced". This should give a Target AFR table for each gear. Put in the same Target AFR values you were using before in gears 3-6, but zero out the Target AFR table for 1st and 2nd gear. This will make it so that Autotune is only running in gears 3-6.
Once you come up with a pretty good map for 3rd gear, copy the fuel change values into your 1st and 2nd gear table.
FYI...On most modern sportbikes there is typically no need to tune each gear independantly. There are some guys on the forums that claim it makes a difference, although I have never personally seen it make a noticeable difference on the bikes I have tuned. That said, I have not tuned a BMWS1000RR before, so it may be different.
Hope that helps. Let me know if I can answer any other questions you have.
Best,
Timmer
I really appreciated your help.Thanks

Hey DrIoannis,
Hmm...that map does look a little strange. There's definitely something weird going on.
Here are a few things that come to my mind to check:
1. Did you unplug the stock O2 sensors? If you didn't then you will have the ECU's Autotune and Power Commander's Autotune fighting each other.
2. Do you have an error codes on the Power Commander? You can check this in the Power Commander software.
3. Have you updated to the latest firmware? You can find this on the Power Commander website.
Those are the things off the top of my head...
In answer to your other question about the quickshifter...
Autotune only works within a window of AFRs that is specified in the Power Commander. We did this so that Autotune would not run during cases like quickshifting when the AFR goes very lean or also when the O2 sensor goes bad and reads very rich or very lean.
Hope that helps,
Timmer
1)Yes I unplugged the OEM O2 sensors
2)When I connect it to my PC no error codes appear
3)Yes I made an upgrade couple of months ago.
The weird thing is that appears in 2nd gear and maybe just a little bit in 1st.The other gears are very good.
Also would like to know the refresh rate of the Autotune,if there is any (Hz?).
Thanks for the fast response.

I have a BMW S1000RR equiped with Leovinci full system, PCV/Autotune(gear depended), AIM EVO4 for datalogging and have some questions about it.
The O2 sensor has no more than 2000km and I run the test and its within specs.I do not have leaks and blocked the pair valves so no fresh air goes in.In 2nd gear I get really odd numbers.If I constantly accept them then I have hesitation in the 3K-5K area.Below is the map that I got.Something is not right.You cannot have -12 and 250rpms later +36.The 2nd gear is critical for exiting slow corners in the track and I need a really good map.I finally copy/paste a map from the Dynojet library for 2nd gear and I choose not to map it.The other gears have good smooth maps.
Also I would like to know if the quickshifter spoils the mesurments when it engages the gears.As I have seen in telemetry the AFR becomes lean when changing gears with shifters (ex 17:1) for milliseconds.Unfortunately I do not have the LCU-one (AFR mesurment tool of AIM datalogging) to verify on my bike.
Thanks for your time Timmer...

I personally use 32F/30R.They are relatively low pressures and you get shorter tire lifespan.In the track in the CSS(Greece) they suggest 30F/28R.

I have StompGrip on my bike for 2 months and zero problems.The have very good traction and help me when braking.You have to get used to it and learn how to use them.I did not try anything else so I cannot compare.
What Is The Right Pressure?

What is the correct tire pressure for the Dunlop D211 GPRacer slicks (Made in France) off the warmers?I tried them in the 23psi rear and 33psi front off the warmers.Is this correct?
