Description

Embark the efficiency of a true dyno inside your car!

Measure your real engine power and torque within a 2% margin by performing a simple acceleration with your car!

Make sure your tunings are effective using a completely objective and independent way, without any excessive expense!

------------

PerfExpert - Car Onboard Dyno & Timer is an application allowing you to measure the performances of your car, such as its real power, torque, and acceleration times. It doesn’t require any connection to your car. Results are provided as detailed reports featuring interactive charts.

How does PerfExpert dyno works ? It's simple :
1. Create your car profile => Describe your car to PerfExpert by providing information such as curb weight, tire sizes or engine displacement. If you don't know how to find your car's specifications, we help you to do so.
2. Mount your phone in your car => No need to connect your phone to your car. With your phone firmly mounted inside your car, PerfExpert can rely on its internal sensors to measure the real acceleration of your car.
3. Accelerate through the entire engine rev range => On a flat, straight and horizontal road, perform an acceleration from low rev to the maximum rev, keeping the same gear : that's it!

IMPORTANT : dyno test is not compatible with automatic gearboxes that doesn't have a manual mode.

With such a tool, you can check the efficiency of your various tunings, ECU mapping, chiptuning, and even your chassis settings.

Using the specification of the tested car and your device’s accelerometer, the application runs our algorithms and dynamic power loss calculations to provide the performances of your car with high accuracy.

Features:
- Dyno test : measure the power and torque of your engine with advanced loss calculation model. Detection of the engine rev limiter. Detailed reports featuring interactive charts of wheel and engine horsepower and torque / engine speed, just like a regular chassis dynamometer.

- Compute corrected power and torque using the correction norm of your choice (atmospheric pressure, ambient temperature and air humidity are taken into account). Available standards: DIN (Europe), SAE (America), JIS (Japan), CEE (Europe) and ISO (International).

- Timed Run test 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.

- Use of your phone accelerometer at its maximum frequency and advanced signal processing for smoothed curves.

- Custom choice of units from a large choice: Hp, Ch, Cv, Kw, Nm, Ft.Lb, mKg, Mph, Km/h, m, ft, G, m/s², psi, inHg, mBar, °C, °F

- Export reports in Tab Separated Value format and PNG

What’s New

Version 2.2.0

- Measurement procedure is now easier to perform thanks to sound effects that inform you when measurement initialization is done and when the dyno start speed is reached.
- Added more smoothing levels. Now there are 6 levels (Low, Low+, Medium, Medium+, High, High+).
- Added a new information to results : data acquisition rate.
- Added Russian, Bulgarian and Norwegian translations.
- Updated translations.
- Now, when your connection to the PerfExpert Network has expired, the app prompts you to reconnect
- Fixed the speed unit in the measurement screen when unit is Mph
- Fixed car profile description in the results Average screen

Bon application

Ayant une voiture d’environ 200cv j’obtiens des valeurs entre 196cv et 209cv... assez précis.
Cependant pour avoir des valeurs réalistes il faut bien respecter à la lettre tout les critères!
Ce qui prouve que tout les éléments de calculs sont bien pris en compte.
Un peu chère quand même mais toujours moins qu’un passage au banc même si ce serait plus précis cela permet au moins d’avoir une idée approchée de la puissance.

Superbe innovation 👍🏻👍🏻👍🏻

Appli au top ! 👍🏻
Encore faut il qu’elle soit bien calibrée en rapport avec le véhicule testé !
Résultat très proche d’un banc d’essai...
Je la recommande et la conseille à tous ceux qui n’ont pas les moyens de ce payer un passage au banc de puissance... pour quelques euros vous pourrez le faire vous mêmes 😉

Developer Response ,

Merci pour ton feedback!
