Back in 2007 when I got my 1st Prius, I also purchased a Prius Prime graphical emulator. It showed RPM of the ICE, MG1 and MG2 fuel consumption with acceleration and/or MPH that you put in. It even considered wind speed and direction. It was from a fellow in Australia that had a fully instrumented Prius and a test track to test it on without interruption. Alas Windows 10 broke it at some point, and this clever hard working Aussie quit supporting it. Does anyone know of such a graphical emulator now? Prius AND Prime would be pretty cool.
