Review on XTOOL Automotive Bi Directional Diagnostics Programming Tools & Equipment at Diagnostic, Test & Measurement Tools by Julio Diaz

Great tool. I chose the D9 because I really like the topography and the large screen. Shows you codes that the "idiot bulbs" on the dashboard don't show. For example, I have a bad temperature flap motor on the passenger side. In summer it blows cold so well, and there isn't so much heat, I would have no idea of a touch of cold in winter. If you educate yourself a little you can learn a lot, for example you can look at both short term and long term fuel trim values which can tell you a lot. You can record all the real-time data when you are driving at 65 km/h on the highway for example, and record the data that you can view at any time in the future because it is stored on the tablet. Repeat this in a few months and see if there is anything to be prepared for. It's just a great way to keep an eye on the condition of your car and keep it out of the shop or at least know what's up with it before you hit the road!
