I was wondering if there was any AutoControl IIIB service any where near Northern Virginia that could tune this thing to tighten up a little. It sort of works in Nav mode with the GPS, but it can go off course by 10*, correct and overshoot by 10* the other way. Never seems to dampen out. It held to about 1-2* before I had to replace the DG, but now it's all over the place. Just looking to get it dialed in a little better until I have funds to replace with something a lot better.
