First thing I would do is bump up the cya to the recommended 60-80 ppm. From everything that I have been able to find out (and from what I have seen in my own pool and in the water testing histories of my customers with SWGs the higher cya levels do make a difference because of the way the chlorine is introduced into the pool with a SWG as compared to manual chlorination. I would have the salt level checked at a pool store or with an Aquacheck salt test strip (they actually are pretty accurate!) and see what readings you get. It is possible that the PoolPilot is off calibration and can be recalibrated to a known accurate salt reading. As far as the adjustments, I am not that familiar with the with the Poolpilot settings but perhaps PoolSean will chip in and get you straightened out! You might want to start in thread in the Chlorine Feeders and Salt Generators section asking how to set the unit up. I know he monitors that one!
