So I have a Hydra chip in my PSD, and it has been set for 10 positions. I also have another PSD I am stripping parts from and either selling them or keeping donor parts for down the road. Now for my question, I wanted to test the IDM and what easier way then plug it into my truck and see if it works, but will I loose my Hydra chip settings? I have looked around for an answer but havnt come up with one through the forum boards. Can someone enlighten me. Thanks guys.
