WHY the Smart Box?
The renowned VAREX Exhaust System was invented and manufactured by XForce Performance Exhaust. VAREX Exhaust has since been the most popular choice among the enthusiasts and professionals, who are seeking the flexible control of the sound level for their performance exhaust.
VAREX exhaust system allows users to adjust the exhaust sound from stock-car like quiet to sports-car like growl by a click of a keyfob button.
We love our VAREX exhaust sound and performance, and we would prefer keeping the Varex exhaust on the “Open Mode” most of the time.
However, there is always some moments, the high volume exhaust sound is less desirable. We know that is the nature of most performance exhausts.
Imagine the following scenario: when you are cruising in a beautiful stretch of country road, slightly tapping on the throttle pedal just to maintain the cruising speed, or simply let the cruise control taking over, most likely we would hear a low pitch, slight(or loud) humming exhaust sound resonating inside the cabin.Some of us might be fine with it, but to the others, it could be a little bit too much to bear, especially during a long trip.
With Varex muffler installed,we could have reached for the Varex remote key fob, and quickly pressed the button to reduce the sound level. It is a good way to go, but yet not the most convenient one.
We can’t stop but start thinking, what if we can create a device that will know when and how to change the exhaust sound for us, and do it precisely and automatically.
It will mean that this smart control system can sense the right moment, and produce the right exhaust sound for our enjoyment.
Gladly, our R&D team took up this challenge, and that was how the idea of Varex Smart Box Bluetooth® Exhaust Controller (VSBec) have been contemplated and created.
Our goal is to make the most user friendly Variable Exhaust System, and reduce the stress of owning a loud performance exhaust.
What is the Smart Box:
Varex Smart Box is an electronic control device that let the user to manually and automatically adjust the exhaust sound level of the Varex exhaust. The users can operate and make change to the settings of the Smart Box via an elegantly designed Smartphone App.
Smart Box provides the following functions:
What is the Manual Mode?
Previously the variable exhaust valve of VAREX muffler was controlled by a key fob, something similar to a car door key fob.When user presses the the button on the key fob, the exhaust valve will starting turning until the pressing is stopped.
It works ok, but it is not perfect.
The users are not able to precisely control the valve position, and there is no feedback display of what the valve position is. Furthermore there is no memory for any pre-set valve positions.
The urge for meeting the demand for more user control of VAREX has been driving our team to design the most user-friendly and precise controlled device by far for Variable Exhaust , which is the Manual Mode of the Smart Box.
By Manual Mode, you can select the 5 pre-set valve positions, which are default to be “Closed”, “25%”,”50%”,”75%” and “Open”.
It is already big step forward, however,we were not stopping here.
We went on to designed a procedure to let our users set those Pre-set valve positions by simply holding one of the middle three pre-set buttons, a custom setting page will elegantly flip out for picking the desired valve position, and this newly set position will be recorded.
How easy and convenient will that be!
Also for those users who don’t want to lose the touch and feel of the old key fob, we have something just for them. There are two arrow buttons on the bottom of the screen, which imitate the old key fob button operation. With much more to it, now you can see the turning progress displaying on the Smart Phone screen to indicate what the valve position is. We have to say, the operation of the valve position progress circle is such a pleasant to look at.
We hope you enjoy the brand new experience of the Smart Box Manual Mode.
What is the Matrix Mode?
In order to change the sound automatically, we need to know how to locate the sound.
There was a breakthrough finding in our research, and it intrigued us.
We can locate the sound by three vehicle parameter value ranges: Engine RPM, Throttle Position and Speed.
Based on this finding, we created the “Matrix Mode”.
We call the parameters value range the “Band”.On the Smart Phone App, we have designed a very user-friendly interface to pick the right band value. Don’t worry, we will show you how this works in the App User Guides section.However, It would be a daunting task for users to know what “Band value” should be assigned.
We have just the solution for our Smart Box users.
We call it the “Band Snap” feature.
It is simple to use, even though it requires assistance from a fellow passenger.
The user can drive the car as usual, just at the moment when the exhaust sound that we want to find becomes prominent, the driver can instruct the assistant passenger to tap the “Band Snap” button within the App, the Smart Box will automatically assign a band value range for each parameter. Users can even further fine tune the band
Isn’t that magical?
Matrix Mode enables our users to easily locate and change exhaust sounds, and do it effortlessly!
