The blue colour of the FlashScan unit isn't an indication of the product type That is the new colour for our hardware with the board changes to accommodate SCI.
I don't know if your unit is Scan Only or a Scan and Tune, that is dependent on what you purchased and what paid for it. The Scan Tool retails for $399, our website retails the Scan and Tune (GM enabled) for $798, and as we haven't released tuning for Cummins, there is no Scan and Tune available (although some of our resellers do sell/dispatch the hardware at the point of order but will provide the upgrade code when it's released).
To assist you further I'll need to know what did you purchase? and from whom?
Cheers
