KPower 3.0.9 is a software that is shipped with all of our VCDS diagnostic systems and the OBD2 Diagnostic Kit as full version. It allows to calculate power (DIN70200), torque and G-factor of a vehicle. Every VCDS (VAG-COM) distribution / diagnostic software with suitable data logging capability can be used with this software.
If you do not own a diagnostic system yet, the easiest way is to purchase our OBD2 Diagnostic Kit which includes KPower.
The program calculates horse power and torque graphs from vehicle weight and speed / rpm data that have to be logged during a driving cycle. You can download the KPower Manual for usage of our software.
This driving cycle consists of an acceleration and a deceleration phase, through which acceleration horse power and torque of the vehicle are measured. This data is then used to calculate the engines horse power and torque as well as the G-factor of the vehicle.
Depending mostly on the street (steady, at least 300m are recommended) and the intelligence of the driver, less than +/- 5% measurement uncertainty are possible.
The intelligent exponential regression during deceleration allows much shorter tracks to be used while keeping a good result.
System requirements: KOBD2Check, VCDS or another suitable OBD software for data logging (vehicle speed, engine rpm, timestamp), Windows XP, Vista, 7, 8, 8.1 or 10.
