I’m excited to see the dynos with a C63S. I’m expecting that it won’t make nearly as much of an increase over the C63S given the additional tuning already done by AMG. Holding on pulling the trigger until I see some of those dyno runs.
I also have an S.....curious to see your results before i buy, 1/4 mile would be even better xD
We were able to get our new C63 strapped down today for a little tuning. Our development car is all stock with around 800 miles on the clock, base model, $68,000 sticker price. Fuel during testing was 91 with a couple gallons of E85 mixed in. We think these results will be repeatable on good quality 93 octane fuel but will retest in the future. Temps in the 70s.
The cliff notes:
1) Stock performed better than expected at 465whp / 490wtq, stock boost was ~9.5psi under these testing conditions.
2) Using the JB4 we raised boost up to 15.5psi peak but kept a nice taper up top to keep things safe. Power jumped up to 537whp / 597wtq.
3) We previously determined that the factory intake is a major restriction so we installed a prototype BMS intake system with the car on the dyno and the reduced restriction allowed it to hit 561whp.
4) We ended up dialing back torque a bit in the end to smooth out the power delivery but there is plenty on tap. This platform can probably break 700wtq if you really want it to.
5) With all the torque on the road we've set the JB4 to limit boost in 1st and 2nd gear for improved traction. It's a nice JB4 user adjustable option there for you when you need it.
Also worth mentioning the JB4 is different animal than all of the other C63 tuning boxes currently available for the platform. Offering CANbus, fuel control, wireless logging to your smart phone, and a lot more to be discussed later. We're just getting started here.
That will probably have to be customer provided, getting in to smaller and smaller segments of the market. But we're more than happy to work with any E63S customers on custom tuning once their JB4 is installed. Just email in a log and we'll help ensure you're getting as much as you safely can from it.
Hi Guys
I just finished up fitting my JB4.
I still have the same tune from when I had the the stage #1 pure turbos, Ive just put in the stage #2 pure turbos now and the Wiestec intakes and the JB4 for data logging (and WMI down the track ) Ill post up some logs in the next couple of days
Have the jb4 installed on my c63s .Finally figured out the bluetooth connection and was able to start logging . Seems stronger already on map 1, however trying to figure out the bugs with map 2 and 3 . Check engine light comes on after driving around on map 2 or 3 and has no power at all and barely will get up to speed. So far, the trick is to clear the codes and switch back to map 0 or 1 .
Uodate**
So the car will run rough after a few minutes and cut our power and turn off .have to turn off the car, clear codes, turn on and it will go a few blocks again before reoccurring

Let me know what you find out. Had major issues when I installed mine so I have it all disconnected right now.

I’ve gotten mine but haven’t installed yet. It’s a ***** to install compared to other piggybacks but that is because the JB4 intercepts the sensors and MB hid those connectors very well.
have to admit I’m not very excited reading the last posts over here..
