I want to unlock the Mercedes Benz factory top speed limit which is 250km/h. Which program can I use to unlock it? and how to remove the speed limit set from the factory? Check tutorials below:
MB Star DAS/XENRTY: No
DTS Monaco: Yes
You could do them offline using Vediamo or Monaco but from an experience you better of with MB SD Connect C4 or VCI multiplexers to used those software. Meanwhile, you will need special CBf/Vsb/smr file or seed-key calculated to get the required access to the ecu and cpc. Some people can help you with that calculation. Unfortunately, we don’t.
In a word, you will need Vediamo/DTS together with the correct files (vsb w cbf) or regular file with seed key (bought) to gain access for coding.
