KPower 3.0.9 – vehicle horsepower measurement using VCDS & OBD2. Calculate HP, torque & G-forces from acceleration data. Precise, repeatable, short coast-down distance.
Calculate engine power (DIN 70020), torque and G-force without an expensive dynamometer - simply record a drive cycle via OBD. Works with any VCDS (VAG-COM) distribution or other diagnostic system capable of data logging.
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.
KPower offers a cost-effective way to accurately and repeatedly test a vehicle's performance. By integrating with VCDS diagnostic systems and the OBD2 Diagnostic Kit, the software is easily accessible and user-friendly. Thanks to intelligent exponential regression during coasting, the required coasting distances are significantly shorter than other tools. This leads to precise results without the need for long measurement distances. The KPower software is therefore an efficient and affordable solution for performance measurement.
System requirements: KOBD2Check, VCDS or another suitable OBD software for data logging (vehicle speed, engine rpm, timestamp), Windows 8, 8.1, 10 or 11.
