Clones typically cost between $180 and $250 . The original tool retails for over $1,200 plus subscription fees.
| Feature | Alientech KESS V3 (Genuine) | Kess V2 / K-TAG Clone ("V3 Clone" Misnomer) | | :--- | :--- | :--- | | | OBD, Bench, and Boot programming all in one tool. Continuously updated via official software. | Primarily OBD for Kess V2; some bench/boot with K-TAG clone. Limited to older ECUs (typically pre-2009). | | Performance & Hardware | Features one of the fastest processors in the industry, enabling near-instant checksum calculations. | Uses outdated components and firmware. "Reworked" clones can improve stability but cannot match original performance. | | Software & Licensing | Uses official "Alientech Suite" software. Requires purchase of separate Master or Slave version protocols (e.g., for cars, bikes, trucks). | Uses modified (cracked) or older versions of K-Suite software (e.g., v2.23). Prone to bugs, crashes, and instability. | | ECU Compatibility | Extensive and growing regularly via official updates. Supports modern ECUs (e.g., MD1, MG1, Denso units). | Very limited. Often fails to read or write newer ECUs and can become incompatible after vehicle software updates. | | Cloning Function | A core feature. Capable of complex cloning, such as full ECU replacement for PSA VD46.1 units by copying EEPROM and MCU data. | Cloning is possible but highly risky. Users often report failures, especially on advanced ECUs like VAG EDC17 series. |
Purchasing and using clone tuning software violates intellectual property laws. For professional automotive shops, using counterfeit tools carries severe liabilities:
If the device malfunctions, there is no official support to troubleshoot the issue 1.2.1. Conclusion: Should You Buy a KESS V3 Clone? kess v3 clone
But as with any popular tool, clones began to appear on the market. These clones were often cheaper and more readily available than the genuine KESS V3, and they claimed to offer the same functionality and performance.
You do not need to risk your vehicle or your business with a counterfeit tool. If the price of a genuine KESS v3 is out of reach, several budget-friendly, legitimate alternatives offer excellent vehicle coverage and official factory support. 1. Genuine KESS v3 (Slave Version)
: Original tools require expensive annual subscriptions for protocols; clones are often sold as a "one-time" purchase but rarely receive new vehicle updates. Availability & Pricing Clones typically cost between $180 and $250
While clones offer a budget-friendly entry point, they carry substantial risks compared to the Genuine Alientech Hardware :
Follow the wiring diagram provided by the software for Bench or Boot mode.
As of late 2023 and early 2024, a true, 1:1 functional KESS V3 clone is largely non-existent or highly unreliable. Here is why: Continuously updated via official software

While a genuine KESS v3 receives weekly updates to support the newest vehicles (including complex secure gateways and modern encrypted ECUs), a clone is frozen in time. It only supports older vehicles whose protocols were cracked before the clone was manufactured. Unreliable Master/Slave Configurations
If, after weighing the considerable risks, you are still considering a clone tool for learning or working on older, less critical vehicles, here is a practical guide based on community wisdom:
