Formulaflash programmer software 1.2.0.0 released BMW 2021+ MDG1 ECU bench unlocking feature. Here is an example of a locked MD1CP032 ECU. Formuflash unlocks this ECU in bench mode; no opening ECU required.
Quick search "Unlock" and select BMW bosch MD1CP032 ECU.
Choose bench mode and check wiring diagram.

Connect ECU with the Formuflash programmer via jumper cable.
Watch out the
small pins, use the smallest in the attachment box.
Click Connect in Unlock menu. It will unlock the ECU automatically.
Then read and save the ECU data.

Then write ECU. Formula flash will also do checksum correction.
Magic Motorsport Flex support for the VAG Group expands even further. With version 8.13.0.0, it is now possible to program the Bosch MG1CS111 ECU, equipped with a TriCore TC298 processor.
Thanks to Boot Glitch unlocking, it is possible to work on the ECU completely independently, including in Bench mode, without the need to ship it to our laboratories.
A solution that simplifies the workflow and ensures full control over the entire operation.
The new support is available to all customers with a Flex Full Master (FLS0.5M) or Flex Full Slave (FLS0.5S) license.
