PerfExpert allows you to measure the power and torque of your engine and the acceleration times of your car (0-60Mph , 1/8mi , 1/4mi... ).

PerfExpert is a reliable and cheaper alternative to chassis dyno and professional timers. By carefully following the usage instructions, you will get accurate and consistent measurements allowing you to compare your tuning, engine adjustments or ECU mapping.

- Individual choice of units from a large number: Hp, Ch, Kw, Nm, Ft.Lb, mKg, Mph, Km/h, m, ft, G, m/s≤, psi, inHg, mBar, °C, °F

- Timer test mode to measure your 0-60mph, 0-60ft, 0-1/8mi, 0-1/4mi, 0-100km/h, 0-20m, 0-200m, 0-400m, and much more.

- Excellent measurements consistency for accurate comparisons.

- Detailed reports of dyno runs and timed runs with specific information for each type of measurement.

- Export reports in Tab Separated Value format and PNG.

Excellent A bit difficult at first, maybe also because I drive an automatic. But the results are spot on, very impressive for "only" an app compared to a rolling road.
