2-1

Be wise when you purchase a Xentry DAX Multiplexer as there seems to be a lot of cloned versions on the market. Unfortunately, there isn’t a good way to know what is original or not. Buying DAS Xentry program Diagnostic Software for Mercedes Benz on Amazon at least adds an extra layer of protection in case there is an issue. We would not recommend buying from retailers that ship from China on eBay. Yes, you can return those units if there is a problem but you will have to pay return shipping and will not know if you are getting an original unit. We do not endorse any of these sellers and do not know if these are authentic versions.

2. What is Developer Mode Extension for DAS.

Developer extension of the DAS for Mercedes-Benz vehicles allows in-depth configuration and programming of the control units. This option is typically enabled for the factory version of the scanner. It was meant for development and testing purposes of the onboard electronic systems. It will allow the user to change the configuration of the car. For example, you can change the ECU, program to use a different engine model, change the speed limit or torque settings and a lot more. Using Developer Mode without knowing exactly what you are doing can be dangerous.

eCom Compare with SD Connect C4

Here is some feature about eCom, MB Star C4 and Xentry Connect . Hope can help you choose right tool.

eCom – laboratory\development tool. Most cheap and light. Can’t be used with DAS\HHT vehicles. Does not support kline communication. Need to be specially setup on any diag sw installation.

SDConnect C4– workshop\robust tool. Most universal in use. The only limitation is kline communication in Vediamo from ver5* Easy to setup. In most cases work as is. As for China clones, SDconnect has the best PCB design, the winner.

Stardiagnos Connect – workshop\robust tool. Very big and heavy. Most expensive. Similar to SDConnect because it is like PC+multiplexer in one housing .Has very specific setup as update blue ray disk has not installer but full HDD image with OS + user application. Complicated in installing additional software as you do not have direct assess to operating system.
