Low Cost Obtainment of Vehicle Performance Curves and Values Experimentally by Means of the OBD2 Port

This document presents a methodology for obtaining the vehicle performance curves and values by means of the OBD2 port for a specific vehicle. In particular the Torque - Power engine curves and acceleration performance following SAE guidelines. Additionally we obtain the wheel dynamic rolling radius to get a more realistic performance. The results obtained are compared to a chassis dynamometer test performed on the same vehicle to prove feasibility for a low cost implementation when there is no access to said testing tools.
