The problem in the link you posted was related to the FlashPro, which is independent to what gets uploaded into the ECU. I'm not discounting a software problem, but at the moment it is isolated to yourself. typer86 - did anything change?
I have checked the prev. calibrations which no changes are made in AFMfuel or injector opening time/VTC Profil.

So Im really have not idea what is happen very strange thing.
I have reduce approx. 11% AFMfuel timing to keep S.TRIM OK again. Currently we do a short retune which is finally finished today or tomorrow...

I had to go 10-12% leaner in afm-fuel, to reach the previous values.

Could the problem be related to the changes for my Flashpro, because of the following datalog-problem, which I had:

I mean, that it is only since these changes.

Or could it have something to do with my ASNU-injectors and/or a software change regarding to Hondata?
Now, if I compare the same Hybrid-Map from the version 2.8.1.0 and 2.8.2.0, the engine now runs too lean!

We must retune it again. Caused by wrong injector duration in the previous firmware...
