Finally ran below 3 seconds in 0-60. I think 2.8 is easily possible since I had lots of wheel spin and full tank of gas. Will start logging this weekend on my JB4 with regular 93 octane. Next weekend will log with 102 octane and see what I can do. I just need to find a good road.

How was the install on the JB4 and did BMS do a custom configuration for the E63S? I have asked in the C63 thread, but they indicated that it was "in development"

Install is tricky I guess. Took my Indy about 4 hours. I have the JB4 set to map 0 until I can log some runs.

I am kind of surprised the JB4 just magically hooks up for Mercedes...
I guess TMAP sensors are the same whether it is BMW/Audi/Mercedes, and whatever OBD magic BMS is doing with the JB4 is universal enough to work for BMW/Mercedes/Audi... or they have some detection code to do different things depending on what kind of car it is in...
Finally have car rolling after battling IAT issue and a boost leak. I think my current setup has a 10.5 at 130 in it with race gas based on fact this run was on the street and using 93 octane.
Top end is still where this car struggles. My best 60-130 has been in the 8.0-8.1 range. I think that is where upgraded turbos would help.

Is this with a tune and JB4? If so, what map? Which map are you planning on using with race fuel?
Big improvement! Stock is 11.2 at best. Probably more like 11.4. Besides two shop cars I think this is the quickest W213 E63 on stock turbos.
i agree the top end (mph) on this platform struggles but hopefully upgraded turbos remedies that.
upgraded turbos also increase spool time/turbo lag, right? not by a lot but it for sure trades power down low for power up top from the dyno charts i’ve seen
11.2s - 10.7s = 0.5s improvement with... i forgot what you have. stage 2 tune, downpipes, filters, and jb4 on 93 octane?

You nailed what I’m worried about. Helping my 60-130 times but hurting my launches and having turbo lag. A buddy that has C63 and Pure upgrade said the spool is noticeable different. Not bad just different
i will never understand why people use a jb4 to add boost when you can just do it in the stage 2 flash. it just seems weird to me.
do you know your peak boost? i’m guessing all in net 4lbs over stock?
What is hard to understand? If you run too much boost on 93 you will run lean. So your options are flashing a 102 tune everytime you run 102 octane or running stage 2 tune for 93 and adding boost via JB4 with push of button. Flashing also has risk of failing.
Also if you just run stage 2 with 93 I don’t think you will get better than 10.9-11.0. That is my experience

see if you can get the mounting pieces needed for the yabeelas
kratos had really good marketing and advertising on a beta for m177

so how this piggy back device can be universal for two cars?
i understand that both cars have m177 marked engine, does it mean both cars share same engine?
