I have the maximus 2.0 I have found two issues with it ... one is that the imperial and the metric settings are backwards.. when you click imperial it acutally shows you the celcius /metric reading and vise versa ... the second thing I have found is that the temperature readings are incorrect I have verified this with my old scanner... the coolant temp never seems to get above 80 some degrees F and the air charge temp never seems to get much about 20 something degrees F , I did notice that the are charge temp starts at about -40 degrees on a cold engine I did not notice what the coolant temp starts at. I have all the latest updates in my scanner I am not sure when a fix will be released for this or if anyone else has come across these problems... other than that I really like the tool
