lol. The best part is that it will plug into any modern vehicle, as it is at that stage where they are just about all obd2 compliant. So you can take it from vehicle to vehicle. Some vehicles give up more secrets than others. For me, it's a great way to be able to see what uses a lot of fuel. It surprised me to see what the people mover was achieving in terms of fuel economy at 90 (petrol auto, flat highway, cruise on). The fuel is sucked during the higher RPM when accelerating.
