Drive with the greatest engine sounds ever heard in a standard car!Now you can experience some of the coolest engine sounds in theworld when they actually follow the engine rpm of your car!You need a car with an OBDII (OBD-2, On Board Diagnostic)connector, most modern cars have one.You also need to install an OBDII adapter (like the ones used forthe Torque app, ELM327 is a common type) in your car, it sends theengine rpm with Bluetooth to the Android phone and let theSoundRacer app play the real sports car and bike sounds when youdrive. Connect the phone to car audio system for a great soundexperience, have fun!The sounds are recorded from famous sports cars and a classicmotorcycle.These genuine engine sounds are included:Big American V8 muscle car - real Shelby soundExotic Italian V10 sports car - real Lamborghini soundLegendary Italian V12 sports car - real Ferrari soundThrilling Japanese V10 supercar - real Lexus LFA soundClassic American V-Twin motorcycle - real Harley soundThere are 5 different driving modes. Most exciting is of coursethe OBD-II mode where the sound follows the engine speed in the caryou are driving. You can also use the manual, automatic, paddle ortilt modes.The OBD-II app experience is as fun and exciting as driving acar with a real SoundRacer product but there are a couple ofdifferences:One feature in the app is that you can change the ratio between theengine rpm and the sound rpm. If, for example, you are driving alow rpm diesel it can be set so that engine sound goes on 6000 rpmwhen the car engine is doing 2500 rpm.The sound and rpm following in the app is depending on the OBD-IIadapter and phone performance and may be different than in theSoundRacer FM transmitter.HOW TO USE:ENGINE SCREENThe Engine screen is the starting screen.
