Image 1: Profile Manager
The Vehicle Profile Manager allows you to create profiles for each vehicle you analyze with ProScan. A vehicle profile stores vehicle-specific information that ProScan may need during a session.
The list box on the left of the dialog displays all vehicle profiles. Selecting a profile in the list will display its details on the right. To create a new profile, simply click the “New” button. When you finish defining your new profile, be sure to click the “Save” button.
ELM Timeout
This value tells the OBD-II interface hardware how much time to wait for a response after sending a command. The default value is 200ms and should work on most vehicles. You can attempt to increase the sample rate by lowering this value. Setting it too low, however, will prevent vehicle responses from being received. If you notice a lot of “?” being received (the “Rx” section of the status bar) when using ProScan, you need to increase this value.
Transmission
Specify if your vehicle has an automatic or manual transmission.
Speedometer Calibration Factor
The speedometer calibration factor allows ProScan to compensate for incorrect speedometer readings due to non-stock tire sizes.
If your vehicle has larger or smaller tires than stock and your speedometer has not been calibrated, you need to specify a speedometer calibration factor so that ProScan can correct your speedometer readings.
ProScan provides a calculator that makes it quick and simple to calculate a calibration factor for your vehicle. Click the “Calculate” button to open the “Speedometer Calibration Factor Calculator” (Image 2).
Enter the stock and current tire sizes to generate a calibration factor.

* NOTE: ProScan cannot calibrate your vehicle’s dashboard speedometer.
Weight
Enter the weight of your vehicle including your own weight and the weight of any passengers that will be in the vehicle during testing. If you don’t know the exact weight, an approximate weight will suffice. Vehicle weight is used by ProScan to calculate horsepower and torque.
Drag Coeff
This value represents the aerodynamic drag coefficient for your vehicle. As of ProScan 4.0, this value is not yet used in any horsepower or torque calculations. Therefore, you can safely ignore this value at the present time.
Wheels
Enter your tire size. If you have different sized tires on the front and rear, use the rear tire size if your vehicle is rear-wheel-drive, and the front tire size if front-wheel-drive.
