I am glad Scangauge II worked for all of you. I bought one in 2008. It occasionally locked up. They sent another one, same problems. No hassle return.
In 2010 I got an Ultra Gauge. It had problems too, I returned it. They reprogrammed it and they told me that they added some programing for it to work in my vehicle. It has worked trouble free ever since and I am very happy with it. My vehicle uses about 5 or 6 percent more fuel than the default settings, was easy to calibrate.
2003 DII is the only vehicle I have tried either one in.
