The 6030 is not the same, and you like how it was previously with
your 4030

The Flytec 4030 (Brauniger IQ) didn't have total energy
compensation. The 6030 (and 5030 and Compeo+ and Compeo) come defaulted at 65%
total energy compensated. This will produce a different feel (and different set
and timing of beeps), for where the thermal is. If you want to go back to your
previous (now brain wired) way of doing it, turn off the total energy
compensation on the 6030 (etc.). (Menu>Settings>Speed>TEC Total energy comp.>0)
You might just reduce it to say 40% and see how that feels, to still get some of
the proffered benefits of total energy compensation.

If you feel that there is too much delay in the vario acoustic on the 6030 in
providing feedback as to when you have entered a thermal? Turn the vario
response delay down from its default at the longest delay (0) to its fastest (4)
or perhaps a bit longer. (Menu>Settings>Vario>Vario response delay)

The 6030 (etc.) Does not sound like the 4030. However, you have a lot more
control over what sound it does produce but you can't get it to sound just like
the 4030. Sorry. Reducing the Modulation and Pitch will also help the 6030 to
sound like the 4030. (Menu>Settings>Acoustic vario>Customize sound>)

Of course, the 6030 is a much more sophisticated instrument than the 4030, but
our brains are many orders of magnitude even more sophisticated (if not as
reliable). You’ve got to use your brain to interpret the functioning of the
newer instrument so that you can have a better match between brain and
instrument, affording yourself of its greater capabilities.

Kraig Coomber turned off total energy (and flies with both a 4030 and a 6030)
after speaking with Steve Kroop at the Flytec Race and Rally. He writes:

Total Energy is all the way off. Delay value changed to 3. Sound:
ascent 600, sink 450, damp 4, pitch 4. I’m still experimenting with the sound. I
would like to get it as close as I can to the 4030.
