IM240 test gives the results in grams per mile (kilometer), the ATS Emissions unit does not graph grams per mile (kilometer), but it will display a value at the end of your test.
The ATS unit will prompt you to enter the beginning odometer reading and engine displacements (in liters). Once this information is entered the test begins and the IM240 driving pattern is driven or simulated on a dynamometer. After the test is complete the ending odometer reading is entered and the test results are displayed (as a number) in grams per mile (or kilometer).
