PerfectPower, the automotive reference on-board system in power and performances measurements!

PerfectPower is, in the form of a revolutionary smartphone application, the automotive reference on-board system in power and performances measurements, the one with the best price / reliability of results / variety of features / operational independence ratio!

It has five major goals:
- Measure the standardized engine power, accelerations (standing and flying start), braking, and max speed of your car
- Calculate the gearbox ratios by rev calibration (as on chassis dynamometer), and measure the free-wheeling losses
- Simulate all the performances of your car (accelerations -standing and flying start-, max speed, ideal maximum revs)
- Measure lap times on track
- Perform engine development with the same efficiency as on chassis dynamometer

And it achieves all this with an exceptional accuracy established theoretically AND proven in practice of +- 1% on average of two measurements for power measurements, which are both its speciality and the most interesting measurements of all in automobile mechanic! Such accuracy is made possible by the accurate, permanent, and clever combination of the informations of the phone accelerometer and the GPS, knowing how to take the best of both sensors while eliminating the specific disadvantages when used individually.

Such accuracy can even be further improved and go well below the % by using an external GPS of 10 Hz minimum communicating via Bluetooth with the application, especially if -as it happens unfortunately with some phones!- the GPS of your phone is notably inaccurate! PerfectPower recommends two in particular:

1) RaceBox Mini & Mini S (25 Hz & 0.3 m average horizontal accuracy), the new reference external GPS. PerfectPower, new partner of RaceBox, drives it since its version 6.1.

2) SkyPro XGPS 160 (10 Hz & 2.5 m average horizontal accuracy), the old reference external gps, regular winner of Internet comparisons. It is compatible with PerfectPower via a third-party Bluetooth GPS app.

In summary, here is exactly what you will need to use PerfectPower with an optimal efficiency:
1) The application
2) An external GPS of 10 Hz minimum communicating via Bluetooth with the application (not essential, but recommended)
3) The Wixgear universal magnetic windshield mount (not essential, but recommended)
4) Perform your measurements in both directions of the road (if possible of course) and ask PerfectPower to average them in order to eliminate the very real influence of the slope of the road and the wind on the results

When these conditions are met, PerfectPower has proven that:
- It was as accurate for power measurements as the best chassis dynamometer (Rotronics Autoscan FI 4x4 synchronized)
- It was as accurate for acceleration measurements as the best external GPS (RaceBox Mini)
