Focus points on the Mercedes Scn Coding Service

 

1. Safety

You can save the current coding formation, this enables you with a safety net in case you get passed away with coding (we have all been there). This means that at any point or situation if you feel that you have gone a bit too far with coding or if anything goes wrong, we can always go back to the start.

2. Versatility

Another exceptional side of our Mercedes coding is the versatility – you can code items in groups, you can pick individual items, in some cases, you can even see the co-dependencies between module groups in terms of coding, a sense that the software may direct you that another module needs to be coded too, for one function to apply.

3. Speed limiter – the speed limiter is again controlled by the same two modules and once again we need to have in observance that the CPC has pre-defined values for that too and we can reach the maximum so do not expect 330 km/h+ from the same C180.

4. Exhaust flaps settings – this is another one of our cool single button settings, as most tuners know, turbocharged engines love additional flow, this function allows for said flow to be customized according to our needs.
