I never really remember having an issue with this before, but tonight I was trying to make some changes to the "target O2 value" from the Oxygen sensor drop down. But everytime I would make a change, then hit enter, close the window and come back, and my changes would be gone. I tried it multiple times with the key on, and several times while idling, but nothing seems to get my changes to stay. Funny thing is, any change that I made to the main fuel map would change and stay just fine. Anyone have any experience with anything like this with the Holley Commander 950?
