I may be a little bit of Mycron fanboy but the unipro software really lets the hardware down. You are just heavily limited with what you can do with it. I found myself exporting to excel to do most things useful with it.
However if all you want to do is look at RPM, Speed, Temps and G Force (and compare between drivers) then it is perfectly adequate. If you want to do anything a little more advance, like adding calculated channels or make you own charts then racestudio with the mychron is more useful to you.
