Special Codings for A/CLA/B/GLB! (PDF)

You can try other options one by one, maybe you will find a better option than the one I found and share it here so that everyone can benefit.

I have some updates on the DP parameters testing for the Sport Plus. I've coded the DP parameters below and have been doing test drives for some of them. Here's a summary of the results so far:

DP Param SPORT_PLUS wo Lvl M2 wDriveS cw122020: Shows {SPORT, SPORT, SPORT} and produces a real effect
DP Param SPORT_PLUS cw222019: Shows {SPORT+, SPORT, SPORT+} but produces no real effect
DP Param SPORT_PLUS wDriveS cw222019: Not tested in real driving yet, but it shows {SPORT, SPORT, SPORT+}
DP Param SPORT_PLUS wo Lvl M2 AMG cw232019: Shows {SPORT+, SPORT, SPORT+} but produces no real effect
DP Param SPORT_PLUS wo Lvl M2 RideSplus cw222019: Not tested in real driving yet, but it shows {SPORT, SPORT, SPORT+}
DP Param SPORT_PLUS wo Lvl M2 cw232019: Shows {SPORT+, SPORT, SPORT+} but produces no real effect
DP Param SPORT_PLUS wo Lvl M2 wDriveS cw222019: Not tested in real driving yet, but it shows {SPORT, SPORT, SPORT+}

I still need to check the NTG6 DP parameters, except for NTG6 DP Parameter SPORT_PLUS AMG X1 cw143017, which rimedre recommended first. I plan to check them another day.

I hope this information will be useful to others.

I have now coded the NTG6 DP parameters for Sport Plus and have run test drives for all of them. Here are the results for the remaining DP parameters.

All NTG6 DP parameters with "wDriveS" in the name show {SPORT, SPORT, SPORT+} and have a real effect on the engine, but they behave like the standard SPORT mode because the engine is tuned to SPORT. For the same reason, they have a real impact on the engine. I doubt SPORT+ has any real impact on ESP as this setting does not work for the engine. However, I can't confirm this as I wasn't sure how to properly test the ESP behavior.

All other NTG6 DP parameters show {SPORT+, SPORT, SPORT+}, but they have no real effect on the engine.

I also tried the "Default" parameter, which simply sets everything to the comfort level {COMFORT, COMFORT, COMFORT}.

To sum it up, I noticed that after showing SPORT+ there was no real effect. I can fully confirm this for the engine in all DP parameters. Therefore, DP Param SPORT_PLUS wo Lvl M2 wDriveS cw122020 is the best option if the goal is to get the most out of all the settings and ensure they work properly. The downside, however, is that engaging Sport Plus mode with this setting still behaves like regular Sport, making using Sport Plus somewhat pointless in practice.

I'm trying not to give up. Am I missing something? Are there other ways to activate the Sport Plus features that will significantly improve the car's performance and throttle response?

In Sport Plus mode, I noticed that the ESP system was activated less frequently, which prevented lag, and I also noticed that the accelerator pedal was more responsive and gear changes occurred a few seconds earlier. The steering wheel in Sport Plus mode is slightly firmer than in Sport mode.

However, the difference is still not enough to reduce the acceleration time from 0 to 100 km/h from 8 to 7 seconds.
A module update may be required to use real Sport Plus features.

I decided to pause Sport Plus coding for now.

Regarding VMAX coding, the main post suggests using CPC_NG, but I noticed that VMAX can also be set in EMS71. Can I use EMS71 instead? I tried to code it in EMS71 but got security access denied (33). The following steps were performed:

1. "Extended Start" for EZS167.
2. "Security Access Level 3B" for EZS167 to open the firewall.
3. "Extended Star" for EMS71 which gave several errors.
4. "Security Access Adjustment" for EMS71 to open access to this ECU.

I also tried running "Extended Start" for EMS71 again after "Security Access Adjustment" but still got the same errors as in step 3.

My SMR-D file for CPC_NG is from the latest version of Xentry, which is not compatible with DTS Monaco. However, EMS71 from the same version of Xentry is compatible and works. I considered using the old SMR-D file for CPC_NG, but I'm concerned about mixing SMR-D files from different versions of Xentry.

This is VMAX for reverse gear.

I know it's VMAX for reverse. I'm currently working on some special coding so the rear camera can work at any speed. I suspect that the VMAX for reverse gear may be preventing the camera from activating, so I wanted to increase that value as an extra step to see if it made a difference. If so, I was planning to set it to the highest possible value, but I was having trouble accessing it. Also, doesn't the VMAX reverse gear require the same access as the VMAX drive gear?

For those who couldn't get the rear camera to work at any speed following the instructions in the main post, has anyone tried modifying the VMAX for reverse gear to get it to work?

 

[rimedre]

I haven't tried changing the VMAX for reverse, but your idea may be correct.

 

[b0snaaaa]

I coded the EMS71 to increase VMAX when reversing over 30 km/h, but the rear parking camera still turns off once I exceed 30 km/h. Before drawing any conclusions, I wanted to test whether the VMAX setting had any effect by dropping it to 20 km/h. However, I was still able to reverse at up to 25 km/h, suggesting that the change had no effect. I also tried disabling the ECO Start/Stop function in the EMS71 to see if my coding worked, but it remained active. Based on this, it looks like none of my changes were reflected, although DTS Monaco did show the new values I was able to code. So I can't confirm that VMAX for reverse is the real reason why the rear parking camera doesn't work at any speed.

I used seeds and keys for variant coding in EMS71, but "Synchronize to Non-volatile Memory Start" failed due to lack of access rights. I assumed that this was not necessary since the coding was only for testing and not for permanent use.

What about Distronic Pro coding instead of cruise control and forward collision warning?
