Yes, I can watch the data flow just fine using serial monitor. The SimpleDyno software has always been a little weird with the serial port even on with the Nano. Usually have to hit connect twice on the Nano but it just will not connect with the Minima. I think the Minima does use a slightly different protocol than the Nano but I don't know enough about the nitty gritty of USB to know what the difference is.
