[SOLVED] SoundRacer V8 V10 V12

Start the engine and rev it up to 2500-3000rpm (revolutions per minute) by quickly pressing down the throttle and then release it. You should hear a short beep in the speakers when the engine is slowing down. The beep indicates that SoundRacer has found the alternator signal. After about 2-4 seconds, when the engine is down to the idling rpm, you should hear two beeps indicating that SoundRacer has detected the idling rpm.

The technology in SoundRacer is based on signals (electrical noise) on the electrical cables from the AC alternator.

The signal frequency follows the engine speed, SoundRacer detects this signal and transforms it to a simulated rpm. The increase in simulated rpm is then multiplied in order to produce a more exciting acceleration impression without running the car’s engine at high rpm. Based on the changes in rpm SoundRacer also produces different sounds: idling, acceleration at lower rpm, acceleration at higher rpm and deceleration, etc.

The engine sounds are transferred to the car radio by a FM transmitter.
