I have the Nology software. The dyno is really difficult to get working correctly. And then finding a strip of land where you can reach 100 MPH's from a stop is a bit difficult to. I gave up on it, because 2nd gear pulls (which only take me to 60 MPH) never seemed to work. And I really don't have anywhere I can take it to 100 safely and legally. So the dyno is not really useful. But pulling and clearing codes is totally worth it!
So this obdmeter stuff at 85.00 sounds like a much better deal!
