Important Features
Live Datalogging
This allows the user to view and save different processes like rpm, throttle position, injector duty cycle, coolant temps, ignition timing, etc., in real time to verify the condition of your car's current state of tune.
Acceleration tests
Based on time and distance measured through parameters such as wheel speed sensors, the user can obtain 0-60mph, quarter-mile and other time values. By using some calculations in addition to recorded data, horsepower and optimum shift points can also be plotted.
Checking/Clearing DTC
This enables the access and retrieval of more than 9000 fault codes with an extended definition to aid repair.
Recode
This allows a user to properly install equipment that needs coding to work - airbags, for example.
Freeze Frame
When a fault code is thrown, the computer will take a snap shot of the available parameters at that instant. Depending on your car, this could show speed, rpm, coolant temp, throttle position and others that might help diagnose the problem.
Readiness Settings
After certain smog-related pieces have been replaced, the ECU needs up to one hour to adapt. With VAG-COM, you can set the values and have the car learn instantly.
Output test
Depending on the vehicle, a user can test components such as an individual injector, or the fuel pump to ensure they're working.
Basic Settings
This allows the user to make throttle adaptations, reset auto-leveling headlights after disconnecting the battery, and other procedures to recalibrate the theoretical starting point.
