Do AutoTuner and KESS3 Support Flex Glitch-Unlocked MDG1?
Magic Motorsport Flex ecu programmer released Bosch MDG1 boot glitch unlocking function — a process that involves removing a resistor, performing the glitch through a dedicated pin, and then refitting the resistor. Once completed, the ECU becomes "benchable," much like a pre-June 2020 unit. However, one question kept surfacing: If my ECU is glitch-unlocked with Flex, can I then use my AutoTuner or Kess3 to read and write it on the bench? The Setup: A Glitch-Unlocked MD1CS003 We started with the same 2025 Bosch MD1CS003 ECU that had been successfully unlocked using the Flex boot glitch protocol. The ECU was now fully unlocked and ready for bench operations — at least with the Flex tool. Our goal was simple: wire it up to both an AutoTuner and a Kess3 using standard bench connections (as if it were a pre-June 2020 ECU) and see if either tool would recognize it as unlocked and allow read/write operations. Test 1: AutoTuner We connected the ECU using the standar...
