About OBD 2 Dyno + Diagnostic
Measure the power of your car with this simple tool! All you need is a cheap ELM327 device.
Note the result is WHP (Wheel HP) which is less than the actual engine power output, due to drivetrain losses.
The actual engine power is 10 - 20 % above the displayed results and depends on your configuration.
(Standard / automatic, AWD, etc).
Beside the Dyno function, you can read and CLEAR diagnostic trouble codes and read real time ecu data.
Preferred usage: connect to ecu,drive in second gear around idle speed, press start button.
Give full throttle until engine speed reaches the rpm limit (or less).
The car weight field should be set to gross weight: curb weight + fuel weight + passenger(s) weight.
Safety first! Consider taking the measurement on a private / closed road with a helper using the app while you drive.

I primarily bought this for the dyno graph portion of the app. It was grayed out and would never work despite multiple attempts. My Bluetooth adapter is one of the better ones and works flawlessly with Torque Pro, DashCommand and other OBD apps. So, for me, this app is worthless. I am using a Galaxy Note 3 running 4.4.2. How do I get a refund?

No connection with ELM327. My cheap adapter connected good with Torque Pro.

The only reason I bought this was for the dyno graph. It is blacked out for my vehicles and inaccessible. Want my money back.

However says my car has 270hp while its a 230hp car. The mass was correct. Also the test results differ between them. It is not straightforward how to start a dyno, for me it starts only if the car is moving.
