Panasonic Toughbook FZ-G1 Ultimate Diagnostic & ECU Remapping Kit – KESS & KTAG
Our Ultimate professional diagnostic and ECU package – combining a rugged Panasonic Toughbook FZ-G1, professional multi-brand vehicle diagnostics, BOTH KESS and KTAG ECU programming interfaces, extensive software, training and 12 months of professional technical support.
This package is designed for garages, professional mechanics, mobile technicians and experienced automotive enthusiasts who want considerably more than a conventional diagnostic tablet.
Unlike our standard diagnostic and remapping packages, the Ultimate FZ-G1 system includes both KESS and KTAG, giving experienced users a much wider range of options for reading and writing supported ECUs.
The complete system is prepared before dispatch with the automotive software already installed and configured.
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.
What’s Included in the Ultimate Package?
1. Panasonic Toughbook FZ-G1
- Panasonic Toughbook FZ-G1 rugged Windows touchscreen tablet
- Grade B refurbished condition
- Fully tested and fully functional
- Professional rugged mobile-computing platform
- Tablet charger/power supply included
2. Professional Multi-Brand Diagnostic VCI
- Your selected professional multi-brand diagnostic VCI
- Cars, vans and commercial vehicle diagnostics according to software and VCI coverage
- Required USB/data leads and accessories as applicable
3. KESS ECU Read/Write Interface
KESS provides ECU communication through the vehicle’s diagnostic connection on supported vehicles.
Where supported, this allows compatible ECU files to be read and written without physically opening the ECU, making it a convenient method for many ECU operations.
4. KTAG ECU Read/Write Interface
KTAG provides additional direct ECU communication methods, including supported bench and boot-mode applications.
This can be particularly useful where an ECU cannot be accessed using the normal vehicle diagnostic connection or where direct communication with the ECU is required.
Having both KESS and KTAG gives this Ultimate package considerably greater ECU communication flexibility than a system supplied with only one remapping interface.
5. Extensive Diagnostic & ECU Software
The FZ-G1 is supplied with an extensive collection of automotive software already installed and configured, including:
- Delphi/Autocom Cars & Trucks – professional multi-brand diagnostics
- WOW – additional multi-brand diagnostics and technical information
- ECU read/write software for the supplied ECU interfaces
- WinOLS – ECU map viewing and editing software
- DPF software
- EGR software
- Lambda/O2 software
- ECU Safe
- Selection of radio decoding software
- AnyDesk – installed for remote assistance from our support team
Additional automotive utilities and supporting software may also be installed depending on the current configuration of our systems.
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.
For this reason, your Ultimate system also includes:
- 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 ECU read/write equipment
- Diagnostic training videos covering common vehicle diagnostic procedures
- Training material to help you become familiar with the supplied equipment and 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.
Your Ultimate package 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, workshop problems and diagnostic procedures 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 FZ-G1 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 the 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, workshops and mobile repair environments.
The touchscreen format also makes it convenient when moving around a vehicle, carrying out system tests or viewing live data.
The FZ-G1 is particularly suitable for:
- Professional garages
- Independent workshops
- Mobile mechanics
- Diagnostic specialists
- Regular everyday diagnostic use
- Viewing live data during vehicle testing
- Road testing and intermittent fault diagnosis
- Users wanting professional rugged Windows hardware
Professional Multi-Brand Vehicle Diagnostics
The supplied Delphi/Autocom and WOW software provides extensive 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 stored fault codes.
This gives you 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 faults which only occur under specific driving conditions.
Multi-Colour VCI Status Indicator
Where fitted to the selected diagnostic interface, the multi-colour indicator provides visual information about the VCI’s connection and communication status.
Vehicle Voltage Monitoring
Supported diagnostic interfaces can monitor vehicle supply voltage during diagnostic operation and provide a warning if 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 & KTAG – Expanded ECU Read/Write Capability
The major difference between this Ultimate package and our standard systems is the inclusion of both KESS and KTAG.
No single ECU communication method is appropriate for every ECU.
On supported vehicles, KESS provides a convenient route through the vehicle diagnostic connection, while KTAG provides additional methods of communicating directly with supported ECUs.
This makes the combination particularly useful for experienced users who want greater flexibility when dealing with different ECU types.
Vehicle and ECU coverage varies. Inclusion of KESS and KTAG does not mean every ECU can be read or written using every 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.
There is an important reason for this.
When assisting remotely, we cannot physically inspect the vehicle, independently confirm 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, it would be irresponsible for us to remotely instruct a customer what map modifications to make to an ECU we cannot physically verify ourselves.
Instead, approximately 6 hours of ECU remapping and map-editing training videos are provided to help customers understand the principles, equipment and software 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, Diagnostic Central has 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 & Diagnostic VCI
When comparing this Ultimate system with another package, consider everything included:
- Panasonic Toughbook FZ-G1 Windows tablet
- Professional multi-brand diagnostic VCI
- KESS ECU read/write interface
- KTAG ECU read/write interface
- Delphi/Autocom Cars & Trucks
- WOW diagnostic software
- ECU read/write software
- WinOLS
- DPF, EGR and Lambda software
- ECU Safe
- Radio decoding software
- Approximately 6 hours of ECU training
- Diagnostic training videos
- System preparation and configuration
- AnyDesk remote-support facility
- 12 months of access to our six-person professional technical support team
This is our Ultimate complete diagnostic and ECU package – not simply a tablet and code reader supplied in a box.
Grade B Panasonic Toughbook FZ-G1
The Panasonic Toughbook FZ-G1 supplied with this package is a Grade B refurbished unit.
Every tablet is fully tested and fully functional before being configured as a Diagnostic Central system.
As Grade B refurbished equipment, the FZ-G1 can show noticeable cosmetic evidence of previous professional use, which may include:
- Scratches or marks to the casing
- Scuffs and general cosmetic wear
- Wear around edges and corners
- Marks to the rear casing
- Light cosmetic screen wear
These cosmetic marks do not affect the operation of the tablet or diagnostic system.
The Toughbook is Grade B refurbished. All other equipment supplied with the package is new unless specifically stated otherwise.
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 and KTAG 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.
