23.03.2026 – Upgrade 2.30

Alientech further expands the operational capabilities of KESS3 with the introduction of the new DataLogger function: the integrated feature dedicated to real-time ECU parameter monitoring and recording.

During a road test or dyno session, you can analyse what is actually happening inside the engine: pressures, temperatures, RPM, air-fuel ratios and many other signals.

In daily workshop operations, this translates into a concrete shift in the way you work: you can accurately understand real engine behaviour, validate calibrations based on objective data instead of assumptions, detect anomalies directly during road tests, and always have a complete history of tests available for comparison and long-term analysis.

How it works in the workshop

• Connect KESS3 via OBD
• Select parameters from the ECU
• Start recording and analyse data

You can view up to 5 parameters simultaneously, selecting the most relevant ones for your test.

Before starting, check signals to ensure correct data acquisition.

During the test, monitor parameters in real time (numeric or graphical view), immediately verifying data consistency. You can also set thresholds to detect anomalies and add markers at key moments.

At the end of the session, all data is automatically saved in the Dashboard, ready for analysis and comparison.

You can:

• analyse test history compare different sessions
• share data with collaborators or technical support
• export everything in CSV

Repetable Tests

Thanks to integrated GPS, each recording includes:

• Position
• Altitude
• Vehicle movement

This allows you to replicate the same test under identical conditions, making results comparable over time.

DataLogger is already included in your KESS3: no additional hardware, no installation, immediately available at no extra cost (with active subscription).

If you already use KESS3, you can start right away.

 

Technical focus

• Connection: OBD
• Real-time parameters: up to 5
• Display: numeric + graphs

Functions:

• pre-test signal check
• min/max thresholds
• markers during test
• integrated GPS

Data management:

Yanhua ACDP2 BMW MSS65 DME Error Chip is Encrypted?

Problem:

Tried to clone BMW MSS65M6v10 DME using Yanhua Mini ACDP2 but failed. ACDP said the chip is encrypted.

It cannot clone all MSS65 DME versions. If the chip is encrypted, cloning that DME will not be supported.

The MSS65 (Siemens, used in ~2006–2010 E60 M5 / E63 M6) has protected/encrypted ISN/SK data (immobilizer secret key) and larger memory areas that block standard OBD tools from full reads/writes.

Later MSS65 units can have BDM partially restricted (rare on M6 V10, but test read first).

Tools like KESS V2/KESS3 or Galletto can flash most of the memory and work for basic data transfer, but the ISN stays locked — so a donor DME won’t start the car without extra steps.

Xhorse vs Autel vs Other Key for Nissan Kicks 2018

Pitted four different smart keys against each other on a 2018 Nissan Kicks, a vehicle equipped with a proximity smart key system. The four contenders were:

• Aftermarket Key: A generic replacement designed to mimic the appearance of the original.
• Xhorse XS Series: A popular aftermarket smart key from Xhorse.
• Xhorse XM38 Series: Another offering from Xhorse.
• Autel Smart Key: A smart key from Autel, a well-known name in diagnostic and programming tools.

All four keys were successfully programmed to the vehicle and had fresh Energizer batteries. The test focused on a single, crucial metric: the key’s ability to be detected by the vehicle’s internal smart antenna to allow for engine start.

The Aftermarket Key: Basic Function, Poor Detection

The test began with the standard aftermarket key. While the remote control functions (locking and unlocking) worked perfectly, the key struggled with passive detection.

When we entered the vehicle with the key, the dashboard displayed an error message and a key warning light. The vehicle did not recognize the key’s presence, even though the remote buttons were functional. The engine could only be started by physically holding the key directly against the start button, indicating a severe lack of detection range.

Xhorse XS Series: Requiring Precise Placement

The first Xhorse key, the XS series smart key, was next. The results were slightly better but still problematic. Like the aftermarket key, it failed to be detected when we simply sat in the driver’s seat.

However, after some trial and error, it was discovered that the key would work if it was moved very close to the vehicle’s smart antenna, located near the driver’s right leg. While this is an improvement over the aftermarket key, the need for such precise placement would be inconvenient and unreliable for daily use.

Xhorse XM38 Series: A Noticeable Improvement

The Xhorse XM38 series key showed a marked improvement in performance. Upon entering the vehicle, the system almost immediately recognized the key, indicated by the prompt to press the clutch to start the engine.

To push the key further, we placed it in his back pocket, exited and re-entered the vehicle. Initially, the key was not detected. However, after a second attempt, the system recognized it. While better than the XS and aftermarket keys, the detection was not instantaneous from all locations, showing some inconsistency.

Autel Smart Key: The Clear Winner

The Autel ikey universal smart key was the final key tested, and its performance was immediately superior. The moment we entered the vehicle with the key, the system detected it and prompted him to press the clutch. The engine started without any delay or need to reposition the key.

Then we conducted more extreme tests:

In the back pocket: The key was placed in the rear pocket, and the vehicle still detected it without issue.

Extreme placement: The key was moved further to the left side of the vehicle’s interior, away from the typical antenna location. Even from this position, the vehicle consistently detected the key and allowed for a start.

Conclusion: Autel Dominates in This Test

For the 2018 Nissan Kicks tested, the Autel smart key demonstrated the most reliable and robust performance. It offered seamless detection from various locations within the vehicle, closely mimicking the performance of an original equipment (OE) key.

The Xhorse XM38 showed decent but inconsistent performance, while the Xhorse XS and the standard aftermarket key required the driver to place the key in a very specific, often inconvenient, location to start the car.

We notes that this is a single test on one vehicle model (Nissan Kicks). The results may vary across different makes and models. However, this comparison clearly shows that while a key may be programmable, its quality and the performance of its internal transponder and antenna can significantly impact the user experience. Further tests on other vehicle models are planned to see if Autel’s superior performance remains consistent across the board.

KESS3 vs Dimsport The Genius Which to Choose

In the world of ECU and TCU programming for chip tuning, two standout all-in-one tools dominate the market: Alientech’s KESS3 and Dimsport’s The Genius (the brand-new tablet version). Both devices now combine OBD, Bench, and Boot/Open modes into a single unit—eliminating the need for separate tools like the older KESS V2/K-TAG or Dimsport’s New Genius + New Trasdata setup.

 

This marks a major evolution for both brands. However, they differ significantly in hardware design, usability, performance, and workflow. Whether you run a busy workshop, do mobile tuning, or specialize in cars, trucks, bikes, or agricultural vehicles, the choice depends on your priorities: raw speed and advanced software vs. true standalone portability. Below is a side-by-side comparison focused on hardware, licenses/subscriptions, features, and real-world use cases.

Hardware & Build Quality
Alientech KESS3

• Compact fiberglass-reinforced box (shock- and vibration-resistant).
• Connectors: DB25, Tyco 12-pin, USB 2.0 Type B (plugs directly into a Windows PC).
• Built-in: Most powerful microprocessor on the market (7× faster than previous generation), GPS, accelerometer, optional Bluetooth 4.2 + Wi-Fi.
• No built-in screen or battery — relies on your laptop for power and display.
• Includes a full kit: OBD cable (with integrated lines for Honda, Volvo, etc.), bench power/comms cables, rainbow cables for Boot mode, and more.
• Operating range: -10°C to +50°C, IPX0 rating.

Dimsport The Genius (New Tablet)

• Rugged 10.1” touchscreen tablet design (compact and field-ready).
• Standalone — no PC or laptop required at any time.
  Built-in lithium battery for wireless operation.
• Dual-band Wi-Fi 5 + Bluetooth 5.2 for updates and remote support.
• Internal sensors monitor temperature, voltage, and current for maximum safety.
• Includes adapter for full backward compatibility with your existing Dimsport wiring harnesses.
• Redesigned intuitive interface with Standard (guided) and Advanced (direct protocol) modes.

Key Difference:

KESS3 is a powerful “black box” that lives in your workshop next to a PC. The Genius is a true tablet you can take into the field or onto a truck/ag machine without dragging a laptop. This makes The Genius far more mobile-friendly.

 

Operating Modes & Compatibility
Both tools now support the full trio:

• OBD (via diagnostic port)
• Bench (connector-based on the desk)
• Boot/Open (direct memory access on opened ECUs/TCUs)

KESS3 adds TCU coverage (automatic/robotized transmissions) without extra protocol costs and integrates DynoDrive — an on-road power/torque measurement tool using the built-in GPS + OBD. The Genius emphasizes safety sensors and seamless use of legacy harnesses. Both cover cars, LCVs, trucks, bikes, marine, tractors, and off-highway vehicles with daily/regular protocol updates.

 

Performance & Features
Speed: KESS3 wins here — its CPU is 7× more powerful, and USB file transfer is up to 10× faster than previous tools (and faster than the old Dimsport Genius). Reads and writes are noticeably quicker, saving time on high-volume work.

Software Experience: KESS3 uses the redesigned Alientech Suite on Windows (cloud-based, daily-updated vehicle database, multi-language instructions, history/favorites, direct helpdesk).
The Genius runs everything on its large touchscreen — no PC software needed. Built-in ticket system, screen-mirroring for remote tech support, video tutorials, and “Dimsport World” news feed.

Extra Perks: KESS3 has DynoDrive for real-world dyno testing without extra equipment. The Genius offers offline operation and contract/license management directly on-screen.

 

Licenses, Subscriptions & Master vs. Slave
Both manufacturers use an almost identical licensing model: Master Version Full file reading/writing in clear text. Ideal for professional tuners who create their own maps.

Slave Version Files are encrypted — you read, send to your Master tuner for editing, then write back. Perfect for beginners or multi-shop networks.

Protocol Activations Purchased by vehicle group (Cars/LCV, Bikes/ATV, Trucks, Tractors/Agriculture, Marine, OHW, etc.).
OBD + Bench + Boot/Open are included in the same activation.

Subscriptions Annual renewal required for new protocols, software updates, and technical support.
First year is typically included with purchase.
Without renewal you can still use the tool with existing protocols, but you stop receiving updates.
Dimsport includes built-in contract management on The Genius screen to track expiry dates.

Pricing Structure (approximate, dealer-dependent as of 2026)

Base hardware + initial protocol packs + 12-month subscription.
KESS3 often starts around €3,000–4,000 for a Master Car/LCV package (plus extras for other groups).
The Genius follows a similar structure (replacing the old two-tool combo of New Genius + Trasdata, so overall cost is usually lower than buying both legacy units).
Annual renewals typically €1,000–1,500 per category or full bundle (exact figures vary by dealer and promotions).

No major difference here — both are premium tools with ongoing costs typical of the industry.

 

Which One Should You Choose?

Choose KESS3 if:

• You work in a fixed workshop with a PC.
• Speed and file handling are critical (high volume or complex modern ECUs).
• You want DynoDrive and the polished Alientech cloud ecosystem.
• You already own Alientech accessories (trade-in programs available).

Choose Dimsport The Genius if:

• You need maximum portability (mobile tuning, on-site truck/ag work).
• You hate carrying a laptop and love a big touchscreen interface.
• You already own Dimsport harnesses (seamless upgrade path).
• Standalone battery operation and offline capability matter.

Many tuners now run both for maximum coverage, but if you’re buying one tool in 2026, the decision boils down to workflow: PC-based power (KESS3) vs. tablet freedom (The Genius).

 

Final Verdict
The Genius represents Dimsport’s biggest leap yet — finally delivering a true all-in-one standalone tablet that obsoletes the old two-tool requirement. Meanwhile, KESS3 remains the speed king with superior software depth and on-road testing features. Both are future-proof, reliable, and backed by strong manufacturer support. The real winner is the tuner whose daily workflow matches the tool’s strengths.If you’re upgrading from older KESS V2/Ktag, New Genius, or Trasdata, both offer excellent value and trade-in opportunities.
