Starting a vehicle tuning business is a significant step. It is not just about buying a gadget. It is about choosing the foundational equipment that will dictate your future workflow and success. The market is filled with options, but the Alientech KESS3 Tuning Tool appears to be a leading choice for professionals.
However, simply deciding on “a KESS3” is not the whole story. At VIEZU, we have structured our offering into two distinct business start-up kits designed to match different budgets and business needs. This guide provides a straightforward look at these options to help you make an informed choice for your new venture.
What is the Alientech KESS3?
The Alientech KESS3 is the latest generation of engine and gearbox tuning tools from one of the most respected names in the industry, Alientech. The KESS3 combines the functions of its predecessors, the KESSv2 and K-Tag, into a single versatile unit.
The benefit of upgrading to a KESS3 is that you don’t need to change tools between jobs. You can carry out the car tune through the vehicle’s diagnostic port (OBD) for quick work, or connect directly to the Engine Control Unit (ECU) in Bench or Boot mode for more complex repairs.
Whether you are reading an ECU for the first time or writing a modified file, the KESS3 tuning tool makes the process as safe and efficient as possible.
Choosing Your Business Model: KESS3 Master vs KESS3 Slave
Before looking at the specific KESS3 tuning business start up kits, the first decision you have to make is whether you want a KESS3 Master or Slave. But don’t worry if you do start with a Slave KESS3, with VIEZU, we can upgrade this to be a Master KESS3 further down the line.
The KESS3 Slave Route
For new tuning businesses the KESS3 is a good option because the tool is ‘tied’ to a Master, such as VIEZU. You read the encrypted file from your customer’s vehicle, send it to us, we modify it and send it back for you to write for you to upload to the vehicle. You can be confident that our files are expertly created and tested on our dyno and come with an insurance backed guarantee for complete peace of mind. The Slave KESS3 route is financially a lower initial investment and a gentler learning curve. You can focus on building your customer base while we handle the complex task of remapping.
The KESS3 Master Route
This KESS3 Master route gives you complete independence. The Master KESS 3 tool can read and write unencrypted files. This means that you have the freedom to purchase or write your own tuning files using specialist tuning software such as WinOLS or StageX. If you choose a Master tool, this is financially a higher investment in tuning hardware and software and training is a must as you will have full control of the changes you are making to your customer’s vehicle. This route is best suited to experienced vehicle tuners who want full control over their product quality.
The Two VIEZU KESS3 Tuning Start-Up Kits
We understand that every business starts from a different level and financial position. This is why we do not just offer a “one size fits all” box. We have curated two specific levels of KESS3 Tuning Start-Up Kit.
To help you decide, here is a direct comparison of what is included in each kit.

When you invest in a KESS3 kit from VIEZU, you are getting more than just a tool in a box. You are starting a partnership that supports your business from day one.

Key Considerations for Buyers
The Subscription Model
The KESS3 operates on a subscription model. While nobody loves annual fees, it is worth viewing this as an investment in relevancy. The subscription ensures your tool gets the latest software updates and new tuning protocols as they are released.

Why “Clone” Tuning Tools Are a Business Risk
In the world of tuning, the temptation of cheap clone tools can be strong for a new business. However, this is a dangerous path. A clone tool is unreliable and risks “bricking” or destroying a customer’s ECU. This is a mistake that could end your business before it has even begun. Purchasing a genuine KESS3 tool from VIEZU is a form of business insurance.
KESS3 Finance: Start for £33 a Week
To make starting your tuning business more accessible, we offer finance packages through Payment Assist.
- Start with no upfront costs.
- Spread the cost over 24 months.
- Low Weekly Outlay: You can start your own mobile tuning business for as little as £33 a week.
- High ROI: With the ability to earn over £250 from a single tuning job, just one job per week more than covers the cost of the equipment.
KESS3 Tuning Start Up Kits Frequently Asked Questions
What is the cost of KESS3?
We have structured our pricing to be as flexible as possible. Whether you want to build a custom package from scratch or buy a “ready-to-go” kit, we have an option for you.
Option 1: Hardware Only (Build Your Own)
If you prefer to build a bespoke setup, you can purchase the Alientech KESS3 Hardware on its own for just £630 +VAT.
This gives you the physical KESS3 tuning tool hardware, which is a blank canvas. You can then add the specific protocols you need. This is the perfect option if you have a specific niche. For example, if you only want to tune Motorcycles or Marine engines, you can buy the hardware and just the Bike/Marine protocols, saving you the cost of the Car/LCV package.
Just remember, the hardware requires protocols to function. You cannot tune with the hardware alone.
Option 2: KESS Start-Up Kits (Ready to Tune)
Most of our customers prefer our bundled kits because they include the essential Car/LCV OBD protocols and battery support you need to start work immediately.
- Start-Up Kit: £2,375 +VAT
- Complete Start-Up Kit: £2,825 +VAT
Option 3: Finance
We know cash flow is king for a new business. That is why we offer finance packages with no upfront costs. You can get started with the KESS3 from as little as £33 per week spread over 24 months. Considering you can earn over £250 from a single tuning job, just one booking a week covers your equipment costs.
What are the benefits of using KESS?
Here are all of the benefits of buying a KESS3 tuning tool;
- Versatility: You get the OBD functions of the old KESSv2 and the Bench/Boot precision of the K-Tag in one single, powerful unit. You do not need to swap tools. One device handles it all.
- Speed and Power: It is significantly faster than previous generations. The processor is far more powerful. This means quicker read and write operations, letting you turn jobs around faster.
- Massive Coverage: It has one of the most extensive vehicle lists on the market. Whether it is a car, LCV or something more specialist, the KESS3 is likely to cover it.
- Peace of Mind: When you buy a genuine KESS3 from us, you are buying reliability. Unlike risky clone tools which can destroy an ECU, this tool is designed to be safe and stable. Plus, with the subscription, your tool evolves constantly with new updates and protocols for the latest vehicles.
Do I need professional training to start a tuning business?
While you can learn on your own, professional training is highly recommended. Understanding the technical principles of how an engine works and the right procedures for using the tool is crucial for safe tuning. Training from a reputable provider like the VIEZU Technical Academy will accelerate your learning and help you avoid costly mistakes.
What happens if I get stuck while tuning a car?
If you purchase your KESS3 from VIEZU, you are never alone. Our technical support team is available by phone and online to help you with any issues you might face. Whether it is a software query or a problem with a specific vehicle, we are here to support you.
Can I upgrade from the KESS3 Start Up Kit to the KESS3 Complete Start Up Kit later?
You can always buy the accessories separately later, but the bundle price in the Complete Kit offers a significant saving compared to buying items individually.
