I have one of these in my Cruze Eco MT, and this DashLogic is great. It does not change anything in the tune or the car, it is only monitoring what is already there. It does not clear codes. Palmer Performance does sell apps that do check and clear codes, but not the Dash Logic. But it offers several pages of gauge info that can go onto the center DIC and on the radio screen display, and either display can be put back to factory display at any time. I connected it to my computer as they show on their web page, and edited some of the pages to what I wanted. I can watch requested boost at the same time as actual boost, or a vacuum/boost combo gauge, or whatever I choose! I love it, and can look at over 50 functions on any screen that I select and can scroll through several pages easily to change which one I am looking at - or can only use one of the two sceens!
