So i am definetelly sure this is due to a bad cartography in the ecu
Well, the important thing is do you have the problem when you put the tre to emulate 4th for all gears?

I was thinking about suggesting you get a tre for troubleshooting, but it is not free, so I did not.

By the way, I run a Gipro atre g2 myself in neutral all gears ("hard") setting to get around my closed loop issue.

When I get a woolich flash kit later I will check if the o2 sensor delete option actually keeps the ecu out of closed loop or just kills the FI light like the o2 eliminators. But for now the atre works perfect and gives a few other great advantages as well.(stp open sooner for part throttle, eliminates fuel cut on decel, and it does not measurable affect ram air compensation)

I apreciate your kind and attention .
Will be waiting for your news.

At this point i must refer some mods on the bike:

- Decat pipe;
- Kn air filter
- No exhaust valve
- Exhaust sensor eliminator ( ese by healtech)
- Akrapovic end can


By posting this video i am looking to find if someone has ever ocurred the same:

Just watched your video. It is 100% the same as the gen 2 behaves when the ecu is in closed loop and the o2 sensors don`t work as they should.. Just look at speed and throttle position in the log i posted. It is the same as your video....

Yes i understand your point but why only 5th and 6th gear? Shouldn't affect all the gears?

This is what i also believe... i am waiting for the new interface to arrive and see how it is

No. Closed loop is only active in 5th and 6th for your bike as I have said. Se below for tps/rpm range.

Let us know how it goes with the troubleshooting.

I have been talking this morning with healtech and 4th gear mode does not apply thr 4th gear ignition advance to all gears... instead of itit applies the Neutral ignition advance and other maps to all gears, wich depending on the map zone may the worth...

I will take the bike for a test today if i have the time and let you know...!

Back again with news....!

Entered the 4th gear map, wich is the neutral map, and guess what? SOLVED!

No more loss of power or "loop"...

Now will work on the neutral map to give her the hard kick she needs!

Good news! Then it`s the closed loop issue.
You can just ride like this, but if I were you I would troubleshoot the problem starting with verifying o2 sensor function + wires, and if the ecu is flashed. There should be no reason for you to need the tre with the o2 sensors in place. Maybe a good "winter" project

So... here we go for the last part of the job.
Ecu reading and inspection ... and then some editing work and finally the flash!

For some reaso this O2 sensors were turned off in the ecu... maybe for damaged o2 sensors, or just because someone thought it would give her some more performance...

Well turned them on and installed again on bike... no errors so far... bike starts fine. I just couln not test it in the road because it is raining...

Meanwhile been working on the maps...

I'll keep in touch
