You have a different SENT system so the V6 firmware posted is not going to be compatible with it. You'll need to load the SENT firmware.

Completely agree with Terry, have my system stable on idle with map 1, 2 & 3 after updated last firmware jb4_mb_c_6. Here are the logs

[aussie644]

Can we get some clarification on the new Maps, please?

Map 4 is now between Map 3 and Map 5, but Map 3 is based on the boost safety (according to the first post), which I think is 3 by default, so it's now between 3 and 6.5, which is also where Maps 1 & 2 are??? This is based on the initial descriptions.

So now, Map0 logs all parameters, and is the baseline logging map right?

Finally, Map 8 is now the Valet Map, which is cool! More specifically, are you able to tell us any more about it, or point me to where I can find out?

Thanks for the continued work!

I'll go fix the first post right now!

Do you need a c43 or c300 to stop by? I have a 2020 c43.

Yes they def need a 2020 c43 to stop by. I also own a 2020 c43 and am patiently waiting for someone to stop by Terry so i can get my jb4 up and running! Thank you in advance!!!

[Terry @ BMS]

I think either one should work for the 2020 model, C300, C400, or C43. They probably all use the same CANbus system. Drop me an email and we can set something up. terry@burgertuning.com

I sent you an email Terry, looking forward to talking.

Hi Terry - Can you share the previous firmware map definitions so I can better understand the changes? I never documented them

[Caruso0644]

Just ordered a 2020 GLE with the 2.0, will this setup work?

[NickMcleanAMG]

wrong thread lol

[Caruso0644]

Isn’t it the same 2.0 in the C300 listed on The tread detail?

Thanks! As an update CANbus fro 2020 models is all sorted now. Updated firmware for those models in the first post.

Whatever notes we want out there we publish in the first post.

Ok... not sure why there's a desire to obfuscate here, I'm simply trying to better understand the relationship between the previous map definitions and newest. Not trying to reverse engineer your logic tree here, just a customer.

[Terry @ BMS]

Normally when things are not documented it's for a reason, like to avoid confusion. We always suggest running the latest firmware and the latest notes to go with them.

Hi,

I was wondering if this forum could be separted into two categories(?)

Becasue c180, 200, 300 have same m274 engines(4cyl.). Where c400, 43, 450 have m276(6cyl).

It would be much faster to read and find exact info. that one's want if theses two were separtated since they have different engines, installation process and so on.

Thanx

Can you check my log please. 98 Octane, Map5, C43
intake + down-pipe

speed: 60-115 Mph

[aussie644]

Bumped my map back up to Map5 and things don't look so hot IMO.

1) It looks like the engine is running really lean on the 0-60 pulls, especially in 1st gear.

2) I'm also getting boost cut between 1st and 2nd and ignition spikes way up (about 25, unusual)

3) Everything just looks a little wonky.

Running E33 with the green wire hooked up.
