As you can see on the SoundRacer Listed Cars page, SoundRacer works fine on most car models on the market today.
If your SoundRacer does not work as expected, then you can try the following:
If there is no first beep or second two beeps, then SoundRacer has a problem to detect the alternator signal and rpm.
This can happen if the alternator signal is too weak compared to other electrical noise on the 12V system.
In some cars the alternator signal is too weak if there is no electrical load on the alternator. (Typical for this situation is that SoundRacer works fine a few minutes after start when the alternator is charging the battery and then fails to follow the engine rpm when the battery is fully charged).
In that case it can help to turn on the rear window heating, headlights, seat heating or other electrical equipment.
In other cars the noice level can be too high on the 12V. Then try switching off the fan, air condition or other potential sources of electrical noise.
If the engine sound repeatedly changes to higher rpm when the engine is idling then try to lock the idling to a higher rpm.
This makes the rpm detection avoid the higher noise levels that some cars have around and below the idling rpm.
Also other problems with rpm following can be reduced by this action.
Locking the idling to a higher rpm: This is done by not releasing the throttle fully during startup, after the first beep you keep the rpm at approximately 1300-1700 rpm until the two beeps confirms the idling detection.
FM radio reception
On some cars the SoundRacer engine sound is weak or disturbed by noice.
One reason can be that SoundRacer is too far from the car radio or the antenna or that the car windows have a metallic coating that prevents the radio signals from SoundRacer to reach the antenna.
The best solution is to connect SoundRacer directly to the AUX input socket available in most modern cars. Just connect the included cable to the AUX output/input socket on SoundRacer.
This is very useful in areas with many FM radio stations where it can be difficult to find a free FM frequency. It may also give a better sound quality in som cars. AUX output is implemented on all SoundRacer V10J and on V8, V12 manufactured after September 2012.
By governmental restrictions the FM transmission power must be very small in products like SoundRacer. One solution can be to get a separate 12V plug and socket cable and try other positions of the SoundRacer inside the car.
Another reason can be that there is a radio station close to the frequency you have selected on SoundRacer, try to find a frequency on the radio were no stations are transmitting on nearby frequencies, example if there is no station on 91,0-91,1-91,2-91,3-91,4 MHz you should select 91,2MHz on the radio and SoundRacer and there would be no interference. We know that in some areas there are so many FM radio stations that it is hard to find an empty space.
It is also depending on the selectivity of the car radio, better receivers has a narrow frequency band and are not easily disturbed by radio stations on nearby frequencies.
If you still are not satisfied with your SoundRacer you could ask the retailer if you can return the units for refund of payment. Many retailers have that policy.
