Panasonic Toughbook FZ-G1 Diagnostic & ECU Remapping Kit with KESS
A complete professional automotive diagnostic and ECU remapping package combining a rugged Panasonic Toughbook FZ-G1, professional multi-brand diagnostic VCI and KESS ECU read/write interface.
This package is designed for garages, mechanics, mobile technicians and experienced automotive enthusiasts who want a complete Windows-based system for vehicle diagnostics, ECU reading and writing, map editing and much more.
The system arrives with the automotive software already installed and configured and includes extensive training material plus 12 months of Diagnostic Central professional technical support.
The Panasonic Toughbook FZ-G1 supplied with this package is Grade B refurbished, fully tested and fully functional. Grade B refers to cosmetic condition – not diagnostic or ECU capability.
Over 15 Years of Diagnostic Experience & More Than 15,000 Customers
Diagnostic Central has specialised in automotive diagnostic equipment for approximately 15 years and has supplied diagnostic products and equipment to more than 15,000 customers.
Before concentrating on our own website, we were also a high-volume eBay seller, regularly supplying around 10 complete diagnostic systems per day alongside a much larger range of automotive diagnostic equipment, interfaces, cables and accessories.
More importantly, we don’t simply sell diagnostic equipment – we are mechanics and use diagnostic equipment ourselves in real workshop environments.
That hands-on experience influences the hardware we select, the software we supply, the training included with our systems and the technical support we provide after the sale.
When you buy a Diagnostic Central system, you’re buying from an established UK automotive diagnostic specialist with years of hands-on workshop experience and thousands of systems already supplied.

Training Included – We Don’t Just Give You the Equipment
Professional diagnostic and ECU equipment is only useful if you understand how to use it.
That’s why our complete systems also include training material to help customers become familiar with the equipment and software supplied.
- Approximately 6 hours of ECU remapping and map-editing training videos
- Training covering the principles of reading, modifying and writing ECU files
- Guidance covering use of the ECU read/write equipment
- Diagnostic training videos covering common vehicle diagnostic procedures
- Supporting material to help you understand the supplied diagnostic and ECU software
12 Months Diagnostic Central Professional Technical Support
This is one of the biggest differences between buying a Diagnostic Central system and simply purchasing diagnostic equipment online.
Every complete system includes 12 months of access to our professional technical support team.
Our support department consists of six trained mechanics, each with a minimum of 10 years’ experience.
This means you’re dealing with people who understand vehicles, diagnostic procedures and real workshop problems rather than a general customer-service department reading from a script.
Our support team is available:
- Monday to Saturday: 9:00am – 9:00pm
- Sunday: 4:00pm – 9:00pm
During your 12-month support period we can assist with:
- Using the supplied diagnostic equipment
- Using the diagnostic software
- Locating functions within the software
- General mechanical and diagnostic advice
- Help interpreting diagnostic information
- Troubleshooting equipment and software problems
- Guidance with common diagnostic procedures
- Remote assistance through AnyDesk
- Remote correction of software/configuration problems where possible
- Demonstrating supported diagnostic procedures directly on your own system
If you get stuck, our team can often connect remotely to your Toughbook using AnyDesk, see exactly what you are seeing and either correct the problem or show you how to perform the required diagnostic procedure.
This is genuine ongoing technical support for 12 months – not simply a product warranty or an email address to contact if something stops working.
Why Choose a Panasonic Toughbook FZ-G1?
The Panasonic Toughbook FZ-G1 is a professional rugged Windows tablet designed for demanding working environments rather than normal domestic use.
That makes it an excellent platform for automotive diagnostic work where equipment is regularly used around vehicles and in workshop environments.
The touchscreen format also makes the FZ-G1 convenient when moving around a vehicle, carrying out system tests, viewing live data or working inside the vehicle.
The FZ-G1 is particularly suitable for:
- Professional garages and workshops
- Mobile mechanics
- Diagnostic technicians
- Regular everyday diagnostic work
- Viewing live data during vehicle testing
- Road testing and investigating intermittent faults
- Technicians who prefer rugged professional Windows hardware
Professional Multi-Brand Vehicle Diagnostics
The supplied Delphi/Autocom and WOW software provides extensive multi-brand diagnostic coverage across cars, vans and commercial vehicles.
Depending on the vehicle, production year and fitted control modules, available functions can include:
- Read and erase diagnostic trouble codes
- Manufacturer-specific diagnostics
- Full vehicle/system scanning
- EOBD / OBD-II communication
- Real-time live data
- Engine management diagnostics
- ABS diagnostics
- SRS / airbag diagnostics
- Transmission / gearbox diagnostics
- Climate control diagnostics
- Instrument cluster diagnostics
- Body and comfort system diagnostics
- Immobiliser diagnostics
- TPMS diagnostics on supported vehicles
- Service interval reset
- DPF/FAP diagnostic and service functions
- Adaptations and adjustments where supported
- Actuator and component testing where supported
Available functions vary according to vehicle manufacturer, model, production year, engine and fitted control modules.
Intelligent System Scan – ISS
On supported vehicles, Intelligent System Scan can scan multiple control systems and display the fault codes stored within them.
This provides a quick overview of the vehicle before allowing you to enter an individual control system for more detailed diagnosis.
Intelligent System Identification – ISI
Intelligent System Identification helps identify the compatible controller fitted to the vehicle and automatically select the appropriate diagnostic parameters.
Automatic VIN Identification
On supported vehicles, the diagnostic software can read the Vehicle Identification Number directly from the vehicle and use this information to assist with identifying the correct vehicle configuration.
Live Data
View real-time information from compatible sensors and control modules while the vehicle is operating.
Live data is particularly useful when diagnosing intermittent or performance-related faults where a stored fault code alone does not provide enough information.
Flight Recorder
Where supported by the selected diagnostic VCI, the flight recorder function allows diagnostic parameters to be recorded during a road test.
This can be particularly useful when investigating intermittent faults that only occur under particular driving conditions.
Multi-Colour VCI Status Indicator
Where fitted to the selected diagnostic interface, the multi-colour status indicator provides visual information about the connection and communication status of the VCI.
Vehicle Voltage Monitoring
Supported diagnostic interfaces can monitor vehicle supply voltage during diagnostic operation and provide a warning if the voltage becomes unsuitable.
Maintaining stable vehicle voltage is particularly important during diagnostic procedures, adaptations and programming operations.
Multi-Language Diagnostic Software
Delphi/Autocom supports multiple interface languages, including English and a wide selection of European languages.
We normally configure systems in English unless otherwise requested and available.
KESS ECU Reading & Writing
KESS is one of the major features separating this package from our standard FZ-G1 system.
On supported vehicles, KESS communicates with the ECU through the vehicle diagnostic connection and can be used to read compatible ECU data and write compatible files back to the ECU.
This method means many supported ECUs can be accessed without removing or physically opening the control unit.
The exact reading and writing methods available depend on the vehicle, ECU manufacturer, ECU type and software/hardware version.
No ECU programming interface supports every ECU or every communication method.
ECU Map Editing & Specialist Software
Once a compatible ECU file has been correctly read, the package includes software for users wishing to learn and work with ECU calibration files.
Included applications include:
- WinOLS map viewing and editing software
- DPF-related ECU software
- EGR-related ECU software
- Lambda/O2-related ECU software
- ECU Safe
- Additional ECU utilities
Important: Any modification to a vehicle’s emissions-control system must comply with the law applicable to the vehicle and its intended use. The inclusion of software capable of editing ECU files does not mean every possible modification is legal for use on public roads.
ECU Remapping Training & Live Support – Important Distinction
The package includes extensive training material for ECU reading, writing and map editing, but our live 12-month technical support service does not include advising customers what changes to make to an individual vehicle’s ECU map.
When assisting remotely, we cannot physically inspect the vehicle, independently verify its exact ECU configuration or guarantee that all vehicle, VIN and ECU information supplied to us is correct.
Incorrect ECU identification, an unsuitable file or incorrect data being written to an ECU can corrupt or lock the control unit and potentially prevent the vehicle from starting.
For this reason, we do not remotely instruct customers what map modifications to make to a particular vehicle.
Instead, approximately 6 hours of ECU remapping and map-editing training videos are supplied so customers wishing to learn can understand the equipment, software and principles involved.
Our normal 12-month support remains available for the diagnostic equipment, diagnostic software, general mechanical/diagnostic assistance and system troubleshooting.
Please Don’t Compare This Package With Cheap Marketplace Diagnostic Kits
Diagnostic equipment that looks the same externally is not necessarily the same internally.
Over approximately 15 years specialising in automotive diagnostic equipment, we have made test purchases from numerous competitors and online marketplaces including eBay, AliExpress, Alibaba, Wish, Temu and other suppliers.
Our own testing and workshop experience has shown substantial differences between apparently similar diagnostic interfaces in areas including:
- Internal component quality
- Circuit-board construction
- Communication circuitry
- Relays and electronic components
- Overall build quality
- Vehicle communication reliability
- Long-term reliability
Many extremely cheap diagnostic interfaces are manufactured primarily to achieve the lowest possible selling price. Two interfaces may therefore look almost identical in an online photograph while being very different internally.
We ask customers not to compare a Diagnostic Central system purely on price with the cheapest diagnostic packages available through online marketplaces.
Our equipment is selected based on years of experience testing and using diagnostic hardware in real workshop environments.
You’re Buying Much More Than a Toughbook & VCI

Tablet Specification & Substitution
The exact specification of the Panasonic Toughbook FZ-G1 may vary according to stock availability.
We reserve the right to substitute the tablet for another unit of equal or higher specification and/or value where required.
We will never intentionally downgrade the computer specification, and the supplied software package will remain equivalent.
Product photographs are for illustration purposes and individual Grade B Toughbooks will vary cosmetically.
Choose Your Diagnostic VCI
This package is available with a choice of diagnostic interfaces, allowing you to select the VCI that best suits your requirements and budget.
The exact availability of features such as flight recording, status indicators and individual vehicle communication protocols can vary according to the VCI selected.
24V Commercial Vehicle Use
If you intend to use the diagnostic interface on a 24V vehicle, we recommend purchasing our 24V to 12V OBD Power Supply Adapter.
Important Vehicle & ECU Coverage Information
No multi-brand diagnostic or ECU programming system supports every function on every vehicle or ECU.
Diagnostic coverage depends on the vehicle manufacturer, model, production year, engine, communication system and individual control modules fitted.
KESS coverage also varies according to ECU manufacturer, ECU type, hardware/software version and available communication method.
If you require a particular diagnostic or ECU function on a specific vehicle, please contact Diagnostic Central before ordering with the vehicle and ECU details where available. We will advise on suitability wherever possible.
