Flashing Tools

From MS4X Wiki

For reading and writing the memory (flash) chips on the ECU you have to use specialized tools.

Luckily there are a variety of flashtools available for free these days. All of the following programs will work for MS42 & MS43 ECUs.

The bootloader area containing EWS key, UIF, etc can ONLY be overwritten in bootmode, regardless of which software used.

Credits of all Chipster software belongs to Kim Freding. Rest in Peace.
