New KESS3 Data Logger Now Available for Cars
A Major New KESS3 Feature Has Arrived
We’re pleased to share an important new release from Alientech for the KESS3 tuning tool.
The new KESS3 Data Logger feature is now available for cars and gives workshops and tuners a practical new way to record and review live vehicle data directly through the KESS3, with no extra hardware required.
For KESS3 users with an active subscription, this new feature is included at no additional cost.
That is a strong message in itself. Existing users gain a valuable new function as part of their current setup, expired subscription users now have another good reason to renew, and workshops using other tools may now find there is even more reason to consider moving to KESS3.

What KESS3 Data Logger Means for Your Workshop
The new KESS3 Data Logger feature has been designed to help workshops capture and review live vehicle operating data for:
- diagnostics
- tuning analysis
- troubleshooting
- performance review
Using the OBD connection, KESS3 Data Logger can record a range of useful vehicle parameters, depending on the vehicle and protocol available. Based on the Alientech webinar presentation, this can include items such as engine speed, vehicle speed, throttle position, boost pressure, lambda-related values, temperatures and more, with GPS-based data also available through the KESS3’s internal GPS receiver when signal is available. The webinar also states that GPS is an added benefit rather than a requirement, so the function can still be used where GPS is not available, such as on an indoor dyno.
For busy workshops, this means more visibility into what the vehicle is doing in real operating conditions, whether that is on the road, during fault-finding, or while reviewing results from tuning changes.
Key Benefits of the New KESS3 Data Logger
One of the strongest points of this release is that no extra hardware is required. According to the launch webinar, the feature is integrated directly into Alientech Suite, so users do not need a separate logging device or additional software to start working with it. The presentation also highlights built-in threshold monitoring, marker points during recording, offline session storage with later cloud upload, cloud dashboard review, session sharing, and CSV export.
For workshops, that brings a number of immediate advantages:
- No additional hardware to purchase for data logging
- Integrated use within the Alientech Suite workflow
- Real-time viewing of selected live parameters
- Threshold settings to help spot values that go too high or too low
- Markers that help identify key moments during a recording
- Dashboard-based review of recorded sessions
- CSV export for further analysis and record keeping
- Cloud sharing options for collaboration or customer review
That combination makes KESS3 Data Logger useful not just as a tuning feature, but as a practical workshop tool for validation, comparison and troubleshooting too.

Why This New KESS3 Feature Matters
A lot of workshops already understand the value of data logging, but one of the barriers can be the need for extra equipment, extra cost, or a disconnected workflow.
That is why this release matters.
With KESS3 Data Logger, the feature sits within the KESS3 environment many dealers already know. It is designed to work through the vehicle’s OBD connection, uses the internal GPS capability of the KESS3 where available, and stores sessions even if there is no internet connection at the time of the test, uploading them later when the tool is back online, according to the webinar walkthrough. The presentation also states that dashboard history stores up to 250 sessions before older entries are overwritten, with CSV export available for long-term retention of important logs.
In practical terms, that gives workshops a more joined-up way to:
- review vehicle behaviour during testing
- compare stock and tuned operation
- spot issues more clearly
- share session data safely
- build better workshop records
For workshops already using KESS3, it adds more day-to-day value to the tool.
For workshops with expired subscriptions, it strengthens the case for renewing.
For workshops using other tools, it makes KESS3 even more attractive as an all-in-one professional tuning platform.
See KESS3 Data Logger in Action
To help show what this new feature looks like in the real world, we have put together a short demo video with Simon showing KESS3 Data Logger in action in our workshop.
There will be a full demonstrations video to follow later this week, including a walkthrough of the feature, how it appears within the software, and how it can be used in a practical tuning and workshop environment.
