CONFIRMED! e372 DIMU stores the parameters (made a quick test with RADIO TYPE and MOTOR OUTPUT) in ROM.
I've not tested if TARE is working so far.

She's now out for a data with the freezer; will report back tomorrow and post the results (will only do one leveled run as Jussi suggested).

Hi,

just checked TARE function on r372.
It's only working when:
THROTTLE = LOW (0)
YAW = LOWER LEFT CORNER (-692)
PITCH = HIGH (+711)
ROLL = UPPER LEFT CORNER (-684)

DEBUG LED will be solid red when stick in these positions; HUD stops spinning and is perfectly level and working.

With PITCH in LOW position position the RADIO VALUES box show me -692.

Any commends?
I'm using a Spektrum AR9020 with two sats attached; the SRXL bus goes to the AQ6 (via custom cable; power supply comes from a motor output since onboard 3.3V LDO is not sufficient for powering AR9020+2x SAT + TM1000).

Hi Joerg

I use the subtrims to set the Radio values to +-700 and 0-1400 respectively.
I cant remember if I have the pitch reversed.

Cheers

Using r381 and board 6.1 DIMU is not saving the values on the ROM. Whenever I power cycle the AQ, it comes back to default parameters from Jussi which I loaded using SD card few days back.

Did you watch the communication console?, because using the stick save command (throttle low, left yaw, right roll, full pitch) it should save and display the message about saving to eeprom.
If you use the save in QGC, it will save to flash and not the DIMU, after reboot the (older) dimu values could overwrite the just saved flash..

So, in short, you must use the stick save command to save to DIMU eeprom, only than it would be used.And watch the com console for the messages.
