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 four major goals:
- Measure the standardized engine power, accelerations (standing and flying start), and max speed of your car
- 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. What - useful precision - is not done without efforts: it is the result of hundreds of hours of work, but also of high skills in physics and mathematics, that myself David Mettey creator of the application have, both by my training and my experience.
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. I currently recommend the SkyPro XGPS 160 (10 Hz & 2.5 m average horizontal accuracy), compatible with PerfectPower, but I plan to add soon the driving of the RaceBox Mini (25 Hz & 0.3 m average horizontal accuracy).
In summary, here is exactly what you will need to use PerfectPower with an optimal efficiency:
- The application
- An external GPS of 10 Hz minimum communicating via bluetooth with the application (not essential, but recommended)
- The Wixgear universal magnetic windshield mount (not essential, but recommended)
- 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 effects of the road slope and the wind
When these conditions are met, PerfectPower has proven that:
- It was as accurate for power measurements as the best chassis dynamometers (Maha, Rotronics, DynoJet)
- It was as accurate for acceleration measurements as the best "all-public" external GPS (RaceBox Mini)
