DIMU calibration

Can someone tell me what might cause this type of oscillation in PH? I had the same problem with an AIMU board I started a thread about it but didnt get a reply, this data is from a new DIMU board. You can see motor output surging when in PH mode.

Can someone from the development team please take a look at the issues above?

Your log looks weired. Did you ever try a standard mixing table with the motors not reversed? All mots connected right?
Did you balance your props? Could you post a pict of your copter or a vid of this flight. It seems that you have a lot of vibs. Your ACCx is going over 5! Ok would be between 0.5 and 1. Same for ACCy.

just a simple question to all of you using the DIMU by now, "did you get a perfect horizon after calculation" and without TARE?
And dont beat me if i missed that point somewere but does the TARE funktion change something inside the DIMU board also?

Did calibrate 4 Boards till now, used the QCG with the DIMU modification, sent the files to other people and they did the cal for me but whatever i do the boards are never perfect level without TARE.

Next step 1, i build a freezing box with a fixed "heat up stand" to get 100% sure the board is perfect level also while static logging. Will see if this changes the outcomming.
Next Step 2, comparing onboard params calculated, default, calculated + tare, tare only just to be clear what is when written

Yes every time, I did 5 calibrations so far and all came out leveled. The tare itself does nothing in the dimu, the EEPROM store function is no active so it only zero's specific params in the current loaded config.
(Which btw isn't stored either until you use a save to rom obviously)

I just loaded last firmware 376 and now we can save in DIMU's EEPROM as well.
Question: is TARE overwriting some calibration parameters (if DIMU calibration was already done and saved in to flash) after using QGC to store TARE values in permanent memory ?
