I don't think Vampire are doing anything fundamentally different to others, but they have done it really well. They're not measuring any external parameters more so than anyone else, throttle position and then the variables available from the sensor wire. The key is in the software and user interface.
I run a 7.5 in my 4wd (and an 8.5 in 2wd), commonly with up to maximum timing. This is because this allows for an extremely smooth bottom end but winding up to a great top end. The difference compared to the manufacturer I ran before and compared to some other manufacturers I've tried when trying others cars is that the software makes the transition completely smooth and linear and as a result it feels like you've motors that are like a 7.5, 7.6, 7.7 etc.
If you're at Batley today you're very welcome to have a go on my car.
