I bought the EVSM-2 last year From Kenneth of Soundracer company.  curiously i never installed it yet.. I played with it yesterday to hear the sound i asked for wich is the GSXR sound.
It look good but i will have to reprogram some feature to have a more realistic gear shift sound. the kit come with a micro SD card input that you can store many different sound files.

On my side i will use thas tank as speaker enclosure for my little 5 1/4 full range speaker. This should give frequency response down to 70-80 hz wich will be good for the idle sound too.

ON my EVSM-2 i have connected the RPM detection with the throttle signal  instead of the wheel rpm. I want to be able to twist the throttle and rev the motor sound just like the bike would have a  neutral too This allow to rev the engine  sound without the need to drive the bike!! I also   installed a 100uF capacitor and a comutation diode  between the throttle signal input and the throttle signal. This make the rpm to have a slow ramp down when i play with teh throttle in "neutral"  and make a moree realistic motor crank inertia, otherwise as soon as the throttle position comeback to zero, the motor sound follow that witch is too fast ramp down and make unrealistic.

I sent them an email in 2013 and never received a reply. How did you get their attention?


I'm trying to get a Tie fighter sound, and I don't care whether it changes pitch with RPM. It seems like this should be simpler than what they're actually doing.

Anyway, the install job looks good and the idea of tying it to the high beam switch is good.

I googled sound systems and found several options. The SoundRacer had a really good youtube of an RC model with the system. I sent an email and Kenneth responded upon return from travels. Fast delivery and options such as speakers, etc.

Kenneth uses, as Doc discussed, a Digital Signal Processor (DSP) to store sound profiles on a removable data flash-chip. So, I am sure he can provide the sound profiles you need, although probably for a fee. I'm considering doing that with an air-start radial aircraft engine when I activate the high-beam switch, and idling engine, unless moving. Doc has really good ideas on sensor inputs, and I'd like the TIE fighter sound, too. I'll make a request of Kenneth for amy custom profile. That also means another switch somewhere on the bike to select the downloaded sound (flash card doesn't have to remain in the DSP unit), unless you are happy with just 1 of the 5 supplied sounds (mine is the Shelby Cobra and rough high-cammed idle).

I glued my unit to the top of the powertank batter. Almost 50% of the battery top is at a level ~2" lower than the rest, and lots of room to silicon glue small items, such as terminal strip, transformers, sound system unit, control input units, etc. I used ~ 15% of this space. I also used a lot of cable mesh/wrap and ties, waterproof connectors, series fuse that is connected to the 12V accessory socket (10 amp rating), everything soldered with shrink-tubing or lugs. The accessory socket also powers my phone while in the RAM mounting system, great for GPS in the hills.

A large speaker inside the standard, non-powertank, tank would be a superior solution to my smaller resin cone speakers. I, initially, had 2 small (~2") rectangular marine speakers glued to the frame between the end of the battery and the plastic tank and they produced stronger treble notes, but minimal bass, and bass is more defining of an engine sound.

Doc has some good ideas...

This is all good to hear. For what it's worth, I've done DSP software programming before, so it wouldn't bother me to write to the flash in a custom way to get what I want.

I like the real sound of the electric engine 

When I converted my trike to Zero electric I needed to put a ankle guard off the end of the motor shaft because it is exposed. I used aluminum because any steel plate there would definitely have hummed with the impulses of the AC motor drive. There is a pretty strong magnetic field around our motors especially on the output shaft.

My Zero often attracts woman, I think there is a pussy magnet in this bike 

I contacted Kenneth at SoundRacer and regarding custom sound profiles. He advised he is very busy and unable to provide the service.

Perhaps someone on this forum knows of a person that can produce the scripts/code for the SoundRacer systems?

Maybe we can reverse engineer it. I'd gladly order a stock system if I could hack it myself.
