Hardware add-on for Flex that reaches the ECU microcontroller through a single contact point, instead of preparing
Korhex is a hardware add-on developed by Magic Motorsport for the Flex programmer. It reaches the ECU microcontroller through a single contact point, replacing the manual preparation on the bench: no resistors to desolder, no Boot pins to wire, no board to turn over. Kit code KRX01.001, on pre-order with the first shipments from 14 September 2026.
Anyone who works in Boot mode knows the tedious part of the job: the ECU has to be opened, the board turned over, the configuration resistors found and removed, then the necessary pins wired by hand. Only then does the software come on and the real work begin.
Every extra step is bench time nobody pays for, and above all it is risk: stressed pads, thin traces next to fine-pitch components, joints to redo at the end. On a customer's ECU, a mechanical mistake costs far more than the time lost.
The difference is not in the software: it is in everything that came before the software. Here is what changes in the workflow.
| Step | Traditional Boot | With Korhex |
|---|---|---|
| Opening the ECU | Required | Required |
| Access to the solder side | Board has to be turned over | Not required |
| Configuration resistors | To be found and desoldered | No desoldering |
| Connecting the Boot pins | Wired by hand, one wire at a time | Direct contact through the kit template |
| Equipment needed | Desoldering station, magnification, wires | Korhex and its positioning templates |
| Risk to the board | Pads and traces stressed at every job | Reduced: no joint is touched |
| Repeatability | Depends on the operator's hand | A guided procedure, the same every time |
| Putting it back together | Resoldering and restoration | Not needed |
The whole flow stays inside Flex from beginning to end: Korhex slots into the access stage and does not change the way you programme.
Once access is obtained, the operations available are the full set for the matching Flex protocol.
It is not a tool for everyone, and that is worth saying before the order, not after.
What you have to buy depends on what is already in your workshop today.
You are already covered on the software side: the Korhex procedures are included in your package. You only need the hardware.
€1,990 + VAT
You can take the hardware and complete the software side: either by moving to a Full licence, or by adding the Flex Boot Glitch FLS0.20M/S licence.
€2,190 + VAT for the hardware, plus €900 + VAT for the licence
Three things are needed: the Flex hardware, the Korhex hardware and the software licence that makes them work together. We will put together the full package for you.
A quotation of your own
The hardware price changes according to the Flex licence you hold. Every figure in this section is exclusive of VAT; the price shown on the page is the one for an Italian private consumer, 22% VAT included (€2,190 + VAT = €2,671.80).
| Flex Full Master or Full Slave with an active subscription | €1,990 + VAT | Reserved terms: we check the licence and apply them before you complete the order. |
|---|---|---|
| Flex with a partial software configuration | €2,190 + VAT | This is the price shown on the page: €2,671.80 including 22% VAT. The Boot Glitch FLS0.20M/S licence is also needed, €900 + VAT. |
| Flex Boot Glitch FLS0.20M/S licence | €900 + VAT | Needed only if you do not have a Full configuration. |
The page shows the price for a partial configuration, which is the one that applies to most orders. If you have Flex Full Master or Full Slave with an active subscription you are entitled to the reserved terms: write to us before completing the order, we check the licence and apply the reduced price. The Flex Boot Glitch FLS0.20M/S licence, needed only without a Full configuration, costs €900 + VAT.
Korhex is on pre-order. The first shipments leave from 14 September 2026 and continue in scheduled batches: orders are filled in the order they were placed, so the date you reserve determines your place in the queue.
We ship in Italy and throughout the European Union, with an invoice. If you are a business with a valid EU VAT number we apply the correct tax treatment at the time of the order.
| Product code | KRX01.001 - Korhex kit |
|---|---|
| Type | Hardware add-on for Flex, not usable on its own |
| Compatible licences | Flex Full Master / Full Slave, or the Flex Boot Glitch FLS0.20M/S licence |
| Operations | Internal flash read and write, internal EEPROM read and write, full backup, Boot Unlock |
| Vehicle and MCU coverage | Updated continuously with the Flex releases: see the Vehicle List |
| Software | The Flex environment, with dedicated Korhex procedures |
| What is in the kit | Korhex device, connector board, MCU positioning templates, USB cable, power cable |
| Manufacturer | Magic Motorsport |
| MCU | The microcontroller: the processor inside the ECU that runs the engine or gearbox management software. |
|---|---|
| Boot mode | A microcontroller start-up mode that allows its memories to be read and rewritten when normal access is closed. |
| Boot Glitch | A family of procedures that exploit a precise time window during MCU start-up to gain access on protected units. |
| Configuration resistors | The components on the board that determine how the microcontroller starts: with the traditional method they have to be desoldered to enter Boot. |
| Full Master and Full Slave | The two complete Flex configurations: Master works on its own, Slave is tied to a Master that supplies its files. |
Korhex is an add-on: on its own it does nothing. The programmer it relies on is Flex by Magic Motorsport.
It is a hardware add-on for the Magic Motorsport Flex programmer. It reaches the ECU microcontroller through a dedicated contact point and carries out the access and unlock procedures on supported units, without the manual preparation the traditional method requires.
No. It is not a stand-alone device: it is an extension built for the Flex ecosystem and it works only through the dedicated Flex software procedures. Without the Flex it does nothing.
The result is the same, the route is not. With traditional Boot you have to turn the board over, unsolder the configuration resistors and wire the pins by hand. With Korhex you place the device on the MCU contact point the procedure shows you, and you touch no solder at all.
On supported procedures, no: that is exactly the problem Korhex was made to remove. Instead of unsoldering, it makes direct contact with the microcontroller.
No. The programming is handled by the Flex, as always. Korhex only comes in at the stage of getting into the protected unit.
It is placed on a specific MCU contact point, shown by the Flex procedure for that ECU model. The kit includes the positioning masks that hold the device in the right place.
It depends on the ECU, on the microcontroller and on the Flex protocol. The list of supported applications grows with each software release and can be checked in the Flex Vehicle List.
With a Flex Full Master or Full Slave configuration the procedures are already covered by the package. With a partial configuration you also need the Flex Boot Glitch FLS0.20M/S licence.
The hardware costs €1,990 excluding tax if you have Flex Full Master or Full Slave with an active subscription, and €2,190 excluding tax if you have a partial software configuration: that is the net price shown on this page. In the second case you also need the Boot Glitch FLS0.20M/S licence, which costs €900 excluding tax. The net prices are the same in every country; the tax is not, and it is worked out at checkout from the delivery country and the customer's status: for an Italian private consumer, with 22% VAT, they come to €2,427.80, €2,671.80 and €1,098.00 respectively.
Because in the first case the software side is already covered by your Full licence with an active subscription, while in the second it has to be completed. The page shows the higher price: if you qualify for the lower one we apply it after checking your licence.
It is the software licence that enables the Boot Glitch procedures on the Flex for anyone without a Full configuration. It is only needed in that case and costs €900 excluding tax: for an Italian private consumer, with 22% VAT, €1,098.00. For other countries the tax is worked out at checkout.
The Korhex device, the connector board, the MCU positioning masks, the USB cable and the power cable. Product code KRX01.001.
The first shipments leave on 14 September 2026. Production is organised in scheduled batches and orders are filled in the order they were placed.
You order now and reserve your place in the queue. The earlier the order, the sooner it falls into a shipping batch. We will let you know when your unit goes into production.
It depends who you are, and next to the figure it always says what it includes. To anyone who has not yet told us, we show the price for an Italian private consumer, 22% VAT included, with the net amount and the tax alongside. If you buy with a VAT number you can tick "I am a business: show me prices without VAT" and see net prices throughout the shop; if you have already declared another country, the headline price follows that regime. The final tax is worked out at checkout, from the delivery country and the customer's status.
Yes, throughout the European Union and beyond. To a private customer in the EU we apply their own country's rate (OSS scheme); to a business with an EU VAT number that checks out on the VIES register we invoice without VAT, under the reverse charge. Outside the EU the sale is not taxable, and any duties and taxes in the destination country are the recipient's responsibility. The scheme applied is stated on the order.
Yes. Korhex is built as a platform meant to grow: new applications and new protocols arrive through updates to the Flex ecosystem.
For the reserved price of €1,990 excluding tax (€2,427.80 for an Italian private consumer, 22% VAT included), yes: the subscription must be active. For using the tool, what counts is the licence that enables the supported procedures: if you are unsure where you stand, we can check together before you order.
