The FLEX firmware loader is a professional programmer for electronic engine control units (ECU) and automatic transmissions (TCU). The equipment is designed for reading and writing software.
Since mid‑2026, the FLEX development team has made it possible to work with locked Bosch MDG1 units using the proprietary Boot Glitch technology, and has also released Korhex to simplify the ECU activation process without the need for soldering!
The online store ECUPro.ru is one of the two official dealers of MagicMotorSport products (Flex, Korhex, etc.)

MASTER & SLAVE
The hardware part of FLEX is the same for either of the two versions. You can choose the type of operation that suits you best.
FLEX MASTER
The Master version is intended for specialists who work with firmware files independently and want to use FLEX as a standalone tool for chip tuning.
FLEX SLAVE
The Slave (slave) version is designed to work in conjunction with the Master. This type of work is ideal for specialists who carry out the processes of reading and writing software from the unit, while leaving the work of file calibration to their Master.
Working with Protocol Modules
FLEX is a modular firmware loader. To work with it, you need to open protocol modules that allow you to work with the vehicles you need. FLEX protocols (FLS) are purchased once and do not require repeated purchase. Currently, FLEX can work with:
-
Passenger cars,
-
Trucks,
-
Boats and jet skis.
-
Motorcycles and extreme equipment,
-
other farm and special trucks
You can find the current list of protocols in the Flex Master Modules tab for the MASTER programmer version.
