Sounds good. I guess JB4 alone will do for now. I did a couple Map 3 and Map 5 pulls on my C63 just JB4 and ~E30. Can someone please take a look ?

Anyone?

Are there any updates on C63S? I am contemplating buying a JB4 instead of going to Eurocharged. Thanks

I just recently purchased my jb4 and as you can see i haven’t gotten much support on my logs.

Looks pretty good. Set open loop to 40 and get another log on map 5.

If you read earlier in the thread it says to email payam@burgertuning.com
You will get a faster response emailing them

How long is the Beta planned to go for? Any refinements and progress being made from Beta user logs and BMS’S own testing to finalize things and end the Beta program stage? Would be nice to see notes on refinements and improvements like the firmware history log on the non AMG Mercedes JB4 page.

[Terry @ BMS]

On BETA we'll remove the tag in the near future, no firmware changes have been needed recently so I think it's pretty stable at this point. Once we have a stable production version we'll start looking in to firmware updates for new features, etc.

Any major differences on M177 for C63s versus E63s that would make you advise to "hold off" on purchasing for E63s?

Hello, I am running now since 4 weeks the JB4 with BMC air filter on map 2/3 and it works fine. I am using German Aral ultimate 102 fuel. I am not sure how much power the car have but it’s definitely more than before ��
Is it also possible to run the JB4 with bigger Turbos or does I need a software upgrade?
I think the car is now at the same level as my BMW M4 with JB4 and d o w n p i p e s was. The d o w n p i p e s aren’t possible this time because of the cops here.


Best regards

[Terry @ BMS]

For larger turbos I think a flash will be required, and then we can use the JB4 on top of that to fine tune it, layer in safety systems, and more.

[achi 3.0]

Is it not possible without a flash. I don’t want to flash my car. Maybe in the future. I didn’t want the maximum of power of the turbos I think only more than now. What could I do to increase the power without to see it. Intake is visible, d o w n p I p e s are to loud.


Best regards

Achi

[Terry @ BMS]

If you're going to do turbos I think you need to plan on a base flash to match.. And then the JB4 can handle everything from there including fine tuning, safety, boost by gear, loggin, etc, etc.

That means bigger or better turbos will not work without any flash. The best way for me will be not to touch anything of the software.
I think on the M4 it wasn’t necessary to flash if you use other turbos, but I am not sure.


Best regards

[Terry @ BMS]

What is the reason for not wanting to touch the software? Due to warranty? Big turbos will void it just as quickly.

No it’s more because I don’t want that I need somebody. At the moment I am free because I do everything by myself and I like it. I change the tune with the app etc. if I flash the car and I need a change I will need somebody to do this.

Best regards

[Terry @ BMS]

If you have traction issues can lower boost in 1st or 2nd gear.. But otherwise enjoy!

[Terry @ BMS]

Hard to say, log of when the performance is slower? We can check the details under those specific circumstances.

[Terry @ BMS]

I'd need CSV file to open in the JB4 interface.

[Terry @ BMS]

The values represent the base boost profile over stock for map6.. The 3psi peak there is a good starting point. Maybe add 0.5psi in areas to evaluate?

hi their,
my dad recently bought a 2018 mercedes E63 S AMG i would like to know the power gains and torque gains on 91 octane and canadien 94 octane. i would like to speak to a tuner that could help me proceed with this and getting me horpower gains and torque gains asap. thank you
Jagger

[Terry @ BMS]

It's hard to predict the power gains on various fuels, etc. But it will gain power.

[Terry @ BMS]

Logs look normal. You're looking at boost spikes as throttle closes since boost is sampled in front of the throttle body.

Under normal conditions you're hitting around 16psi peak in the logs.

[Terry @ BMS]

Got our C63 WMI kits in stock. Expect to hear more about them in the coming days and weeks.
