HISUN ATV, UTV, SSV Tuning Kesens

Who is Tuniverse ?

Tuniverse was born from years of experience in Motorsport and Motorcycles racing and engine control unit remap.
Our mission is empowering the next generation of motorcycle tuners by giving them both tools and knowledge to tune their own Hisun with ecu Kesens with confidence.

We provide for a complete remap solution: xdf (bin definition file), Stage 1 and/or Stage 2 tuned file and expert support, all at affordable pricing.
At Tuniverse, we do not just sell tuning products, we build a community of self-reliant, skilled riders and tuners ready to take control of their performance.
Whether you are a beginner or an experienced tuner, we guide you step by step through the process of modifying the ecu of your Hisun safely and effectively.

Kesens ECU tuning Solutions

We are pleased to announce new tuning support for the latest Hisun ATV and UTV models equipped with Kesens ECUs.

The TunerPro XDF definitions for these vehicles have been developed and tested through a collaboration between OldSkullTuning and Tuniverse.
By combining their expertise in ECU reverse engineering and calibration development with real-world testing, we have created reliable definitions specifically tailored to these Kesens ECU platforms.

(*)What is a XDF? The xdf, otherwise called bin definition file, tells the tuning software how to explain each byte in a the file coming from your ecu’s bike. In simple terms, the definition explains that “the byte at position X in the original file should be multiplied, divided, or adjusted by values W, Y, and Z to produce a real-world value.”
ECU tuning software uses this information to convert raw binary data into a format that is meaningful and easy to understand for the user.

Whether you are just starting out or pushing your bike to the limit, Tuniverse has the right setup for you!

What is a Stage 1 tuned file ?

Stage 1 refers to the first level of performance upgrade applied to a vehicle.
It usually involves basic, non-invasive modifications that enhance power and efficiency without compromising reliability or requiring major mechanical changes.

For ATV, SSV and UTV it always includes the unlock of maximum speed limiter (VMAX off) for L gear and H gear.

Stage1 is done for a full stock ATV.

When the customer changes, for example, air filter and exhaust, it is imperative a Stage 2 tuned file to adapt the ecu and engine parameters to the
new mechanical modifications.

Which engine maps can be modified to achieve satisfying results?

For a Stage 1 tuned file, the following maps can be modified:

• Fuel and injection management
• Ignition calibration
• Torque and engine management
• Throttle control
• RPM and speed limiters
• Other engine protection and calibration parameters
