What Is Korhex?
Korhex is a dedicated hardware add-on developed for Flex users who require advanced ECU access solutions. Unlike a standalone ECU programmer, Korhex works together with Flex Boot Glitch technology and supported procedures to provide direct access through specific microcontroller (MCU) contact points, simplifying advanced ECU unlocking operations.
For supported ECUs, Korhex reduces traditional bench preparation steps by eliminating the need for resistor desoldering, component modification, and manual Boot pin wiring.
Main Features of Korhex
- Direct MCU access for supported ECUs
- No component desoldering required on supported procedures
- No manual Boot pin wiring
- Support for advanced Boot Glitch operations
- Full integration with the Flex ecosystem
- Designed for future protocol and application expansion
Key Advantages of Korhex
- Direct MCU Connection
Korhex enables direct communication with supported ECU microcontrollers through a dedicated contact point. This provides access to advanced procedures that may not be available through standard methods.
- No Component Modification
For supported applications, there is no need to remove resistors or make unnecessary changes to the ECU board. This helps protect the hardware and reduces preparation time.
- No Manual Wiring
Korhex removes the need for manual Boot pin connections in supported workflows. The technician only needs to position the hardware according to the Flex procedure.
- Advanced ECU Access
By combining dedicated hardware with Flex software procedures, Korhex allows access to control units that require deeper unlocking methods.
The result is not only a shorter preparation process but also a new approach to ECU programming through advanced MCU access technology.
How Korhex Works with Flex ECU Programmer?
Korhex has been designed as part of the Flex programming workflow. It works together with specific Flex procedures to provide the required MCU interaction during ECU unlocking and programming operations.
The general workflow includes four steps:
- Connect the ECU
Prepare the ECU and connect it according to the instructions provided by Flex procedure.
- Position Korhex
Place Korhex on the specified MCU contact point indicated by the supported Flex operation.
- Perform Unlocking
Run the access and Boot Glitch procedure through Flex.
- Program the ECU
After successful access, continue with the ECU programming process using Flex ECU TCU Programmer.
Korhex Technology and Future Expansion
Korhex extends the existing Flex Boot Glitch capability with dedicated hardware designed for modern ECU architectures.
The automotive industry continues to introduce more advanced microcontrollers and stronger ECU protection systems. Korhex is developed as an evolving platform that can support new protocols, applications, and vehicle coverage through future Flex updates.
Its main technology advantages include:
- Direct MCU Access:Interaction with required MCU contact points on supported ECUs
- Boot Glitch Support:Hardware support for advanced ECU unlocking procedures
- Flex Integration:Guided workflows and dedicated procedures inside the Flex software environment
- Future Compatibility:Designed to grow with new ECU technologies and applications
Korhex Compatibility and Requirements
The equipment required depends on the user’s current Flex configuration.
1.New Flex Users
Users who do not currently own Flex need:
Flex Hardware+ Korhex Hardware+ Software license
2.Flex Full Master / Full Slave Users
Customers with a Flex Full Master or Full Slave configuration and an active subscription only need to purchase Korhex hardware. The device can then be used with supported procedures included in their software package.
3.Existing Flex Users Without Full Configuration
Users without a Full configuration can choose one of two options:
- Buy Korhex hardware+ upgrade subscription to a full license
- Buy Korhex hardware+ Flex Boot Glitch software license FLS0.20
After activation, supported Korhex procedures become available through Flex.
Frequently Asked Questions About Korhex
1.What is Korhex used for?
Korhex is used for supported advanced ECU access operations that require direct interaction with the ECU microcontroller. These operations may include Boot Glitch and other unlocking procedures available through Flex.
2.Is Korhex an ECU programmer?
No. Korhex is not a standalone ECU programmer. It is a hardware extension for Flex. Flex controls the unlocking process and manages subsequent programming operations.
3.Can Korhex work independently?
No. Korhex has been developed specifically for the Flex ecosystem and operates through dedicated Flex software procedures.
4.How does Korhex connect to an ECU?
Korhex is positioned on a specific MCU contact point defined by Flex procedure. The hardware enables the required communication with the microcontroller during supported operations.
5.Does Korhex require resistor removal?
For supported procedures using direct MCU access, Korhex is designed to eliminate the need for resistor desoldering.
6.Which ECUs are supported by Korhex?
Compatibility depends on the ECU model, MCU type, and available Flex protocols. Supported applications are continuously expanded through Flex software updates. Check the Flxe vehicle list here.
7.Do I need a special Flex license?
Flex ECU Programmer Full Master and Full Slave customers can use Korhex with supported procedures included in their package.
Customers without Full configuration need the Boot Glitch License FLS0.20M/S to access supported Korhex functions.
8.Will more ECUs be supported in the future?
Yes. Korhex is designed as an expandable hardware platform. New vehicle applications and protocols will be added through future Flex ecosystem updates.
