This is my free suite of tools for working with the Rover MEMS3 ECU. It includes MEMS3 Mapper, with full support for remapping (and now live mapping) the ECU, plus support for dual maps with live switching and a utility to reliably recover a bricked ECU. It also includes the simpler MEMS3 Flasher for reading, writing and cloning ECUs and MEMS3 Terminal for monitoring, decoding and logging OBDII communications with the ECU. These tools are all provided free of charge (you just need to purchase a cheap VAG COM KKL 409.1 cable or similar, details provided in the main article here) and run on Windows XP or later, 32-bit or 64-bit.
