OBD2 port ECU flashing
The Best of Mercedes & AMG
The thread has since been deleted because he was wrong and the post was filled with misinformation and speculation. There never has been any development work for a jb4 for the C63S. Disappointing regardless... but it’s not like JB4 is an OBD-II flasher. It’s a piggyback like Dinan.
That was a dumb rumor spread by a C43 owner who has a JB4 on this forum. He said he heard from BMS themselves about C63S development, but was just stupidly just assuming it was coming since both the C43 and C63 are W205’s.

Sort of seems odd that they make something for the 43 but not the 63. I doubt the volume is THAT much more to go after 43 owners, vs 63...unless maybe that exact tune also works on 3XX models, and they get volume that way? Wonder how much different/harder it is to code one for the 63 vs the 43. That’s not my specialty, but you’d think it might be similar difficulty. Maybe BMS can’t secure a C63 to develop on? Still, you’d think someone would loan him one for a free tune when it’s done.
It's why Dinan tested the waters with the piggyback first, to see if there's enough market for everything else in their catalog like suspension & aspiration. Given I haven't heard much from the guys since they launched the piggyback.. I suspect you guys aren't buying enough of the piggybacks to justify the market.

Not to mention, have you seen any marketing whatsoever from Dinan? I can almost guarantee if you told an M3/M4 your C63S was running a Dinan tune they'd look at you sideways and laugh like you had no clue what you were talking about.
Dinan could have even supplied a shop car or customer car with their tune installed to some car YouTuber's. The release and marketing was a pretty pathetic effort on their part in this day and age of everything digital... do you ever see anything AMG on their instagram page? They don't care, they know their audience and where they make the most money. And it's not AMG.
Oh, and add me as another waiting for that bluetooth map switching as well. That's a feature I thought would be available from launch and would be very convenient compared to the **** show that is dongle switching (putting car to sleep, disconnecting battery, etc...)
