Truly an excellent set of diagnostics software. I use an older Bluetooth OBDLink MX dongle on my cars ('99 Sunfire, '01 Contour, and '01 Impala 3800). I can access everything that the computer has access to without any issue (I was amazed that I could access TAP on my Impala, something that used to be only accessible via a $600 Innova scantool). The GUI may not be the most end user friendly, however, it is functional and to the point. I could only ask for the ability to run KOEO & KOER tests.
