Hey guys, some of you know me as Scott Hansen. Datamaster is no longer supporting OBD1 GM vehicles. For all of us that use it we will lose out once we update our computer or updates make it obsolete. I'm asking all of you who hold a license to write to them and express your disappointment.

I just want to follow up on this. After an extensive amount of research I finally figured out TunerPro and believe it to be superior to Datamaster. Datamaster is more user friendly and it took a lot of research it is superior. I'm currently documenting my research in a web page format for others to make it more understandable. The Histogram feature completes every cell.
