My SGII had firmware 3.0 on it.
I've been using the Ultraguage for a while now, and its superior in MOST ways, except nothing ever really resets? It looks like the model that came out a week after I got mine, now has trip gauges that reset every time you start the car. When I fill the tank, the 'trip MPG' or 'AVG MPG' never resets. None of the gauges really appear to reset unless you go and manually reset them.
However, the Ultraguage reads my vehicles fuel cut as 999 MPG, and it shows an extra number to the right of the decimal on most gauges. For things like inst. GPH, this is key. The SGII said 0.3 GPH at idle, whereas the UG says 0.26, a much more useful number. It sure is harder to set up, and a bit less user friendly to use, but 6 gauges at the same time are great.
If my UG had trip gauges that reset, I would have no complaints. I might have to send it in to get it updated, it just sounds like a hassle. I still didn't go through a full tank on the UG, so id like to get it calibrated before I send it off mid-tank.
