Flashing Tools

From MS4X Wiki
Jump to: navigation, search

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 ISN area containing EWS key is only written in bootmode, regardless of which software used.

In addition, we added the two checksum correction tools for MS42 and MS43.

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