David what exactly do you need to know?

This topic may be best discussed via PM or even a telephone conversation. In a nutshell, I'm in a partnership in a 2009 DG1001 that had an LX 7007 Pro IGC installed as original equipment. I have two issues I'd like to get more information about.

The first is rather minor. The airport database still contains the original 2009 data. No update is available on the LX Navigation website. How do I update the airports information?

The second issue is more serious, and a lot more complicated. I have done a lot of work trying to solve it, to no avail. The vario speed command has never functioned properly. It has always commanded a speed that it obviously too slow. I have checked the following:

Pitot/static connections are correct
Proper TE compensation is set (electric compensation)
Proper load/aircraft weight set for the flight.
Proper glide polar set for the glider used for the flight.
Airspeed data received by the device are correct, verified by IAS display on the instrument.

Occasionally the variometer averager does not work (very rarely), and when it does not work, the variometer seems to be acting as if it is uncompensated. This is a new problem that started last season.

The aircraft has a high quality total energy probe, but it is only connected to a mechanical variometer, not the LX7007. The LX7007 is correctly connected for electronic compensation.

I have not checked the quality of the static system. My assumption was that with a new glider, it would be suitable for the LX7007.

The home gliderport for the glider is closed for runway upgrades right now, but as soon as it reopens, I'm willing to check any and all ideas, including the ones I've already tried.

I contacted LX Navigation on both of these issues. They did not respond to the first issue, and suggested I retest the IAS indication for the second. I'm certainly willing to do so, but as I have said, it's been checked.
