if your car is the new body style Cruze... then it is NOT supported at all.. won't work.. I know, because I have both a new body styl e2016 cruze and the old body style 2016 cruze...
The new body style cruze with the auto stop/start crap on it, is not supported at all and can't do anything for it....
the old body style cruze is supported and can be tuned...
and yes, when you try to go into the data logging, you have to wait a while, so it can scan/read the ECM for all of the parameters available... it can take a few minutes.. just wait... gotta have patience man...
