CarPowerTest - dyno bench

This app is engineered to be as accurate as possible, whatever the car, or the phone it is used with, thanks to exclusive processing.
You don't need any connection to use it, the processing is based on your mobile phone's accelerometer sensors.

The accuracy is very close to a real engine dyno, bench, but of course much cheaper.
It has been developped as a diagnostic tool, as a dynometer bench would be, perfect for detecting power losses or improvements (after ECU remapping for example).

0/ Calibrate, once for lifetime. It's very easy and will take you less than 1 minute.

1/ Set parameters (total mass of your car and Cda if you know it)

2/ Fix firmly the device as shown on figure below.

3/ Check there is nothing on the track on which you make the test. Car must be totally motionless.

5/ Just wait until the end of processing (>10s)

6/ Check the Measurement Reliability indicator

7/ CHECK POWER CURVE/ To get full graph with RPM and TORQUE CURVE, enter speed of your car when engine is at 2000 rpm in 2nd gear
