There are no hoses to the MAP sensor, it mounts directly to the intake. They can go bad, I changed one for a friend here locally when it read the equivalent atmospheric pressure of about 70000 feet altitude with key on engine off.
Torque Pro sucks at logging! And it only creates a csv file that you then have to view in something else. Car Scanner Pro excels at ease of data recording & graphing right within the app.
Anyway, in Torque Pro,,, firstly, if you use different vehicle profiles for multiple cars etc. you need to select the one you want to work with. Then select "settings" from the 'gear' menu button. Then select "Data Logging and Upload" . Then at the top select "Select what to log". Then at the top right of the next screen you tap the three vertical dots and once again you select "select what to log" a second time. Only now are we presented with a listing of possible parameters to log. Not all of them will work. Click the checkboxes you want then click OK. This drops you back to a listing of what you have selected to log. We're not through yet! Press the back button and go through the options. Start logging when Torque starts? Log gps? Log g sensors? Set the update frequency, create a new file each time? and so on.... Now if you choose to not start logging with the app start you then must remember to begin logging after you get Torque going. Sheesh! And you still need another app of some sort to view the resulting csv data file.
