installing this week, got the wireless connect and boost controller (BCM) as well.

Awesome!! We've sold tons of these already with great feedback. :zoom:

Congrats !!! How much it cost? Hp/TQ gains? How much boost over stock? Thanks

What is amazing to me is that my 2002 Camaro SS was heavily modded for its day. Stage 3 TEA heads (had to fly cut the pistons), Custom N20 CAM, full 1 7/8 long tube headers, LSX Intake and TB 90mm, electric water pump, lots of weigh reduction, high flow fuel pump, the entire suspension was modded even a-arms and k-member, custom drive shaft, 12 bolt rear end with 33 spline gun drilled axles, full slicks and skinnies, and more I can't even recall. NA it made right at 500 rwhp, and on the spray 605 rwhp and 626 rwtq and was a low 10's car with a best of 10.2 @ 136 MPH

This car is making nearly the same numbers with 1-2 mods, just amazes me how engine efficiency has changed and 700-1000 HP monsters are running the streets!

Can you post one showing gains on an S?

JB4 for 2018 C63S How much with all the options ? ship to TX

apparently its a secret :rolf:

We don't have any dynos with a C63s however the peak numbers will be the same. The delta will be less because the C63s makes a little more power from factory.

Free shipping to US on all JB4 systems!
All JB4 systems come the same, the only option would be to choose which data cable you prefer. I would say to go with the bluetooth.

If you have any questions, I'll do my best to answer them :)

thanks Payam. Are there plans to update the main BMS thread soon with a comprehensive post that will show an install video, recommended base settings by fuel and mods, and also any sort of guide to basic settings for the boost reduction by gear? Last I saw, a while ago, those parameters sounded confusing (ie not just “boost reduction”), and the values had to be entered backwards and not in a logical way.

Basically, hoping for something for the bulk of the users (like myself) that are in stock S’s and just want a clean simple reliable option to set and forget, but still have the nice feature of putting the map back to stock or valet with the phone, and the nice performance metrics that the app gives.

We're working on video install guides to help everyone with the process. Yes, I'll see what we can do with making a video with the boost by gear reduction.
It is a bit confusing, I know what you mean.

Oh man, I'll update our site shortly! I didn't even know the default settings weren't up.
The JB4 will basically auto detect any mods when you add them, a couple logs and it does the adjustments itself :)
You can start with map 1 or 2 and send us logs. That's what we recommend for pump gas 91 (Map1) 93 (Map2+), every car is different so logs do help identify what you can do.

Thanks,
Payam

sounds good. Looking forward to seeing all that. Thanks!

You need a car car to make a video? I’m live in your area.

Thought of a few other questions/comments:

- I wasn't aware about the logs allowing JB4 to auto adjust (auto tune?). I thought I even read somewhere that, unlike past BMW applications, this one does not auto tune.

- Can you help us understand the difference or need for sending in logs to identify fine tuning, vs doing a "couple logs and it adjusting itself"? If there is some auto tuning, is it just limited compared to you pros taking a look at a log and suggesting changes?

- There very well may be "defaults" posted to the site, and I didn't see them. My apologies if that is the case. Not sure though.

Thanks

No, auto tune is different than auto adjust. What I'm talking about are some different JB4 values when changing intake and downpipe etc.
Auto tune will be based off different things which is not on this platform yet. Sorry for the confusion.

For the regular user running pump gas on map 1/2 with some bolts it's PNP no logging or value changing needed.
Just install it and enjoy the much added power!

When going with some e85 blends and methanol or BCM, that's when we'd like to see some logs.
Some adjustments and values will need to be inputted and that's where we can help :)

Thanks,
Payam

Did you get it install yet?

Sorry, I just saw this.

We have our own development C63, thank you though :)

-Payam

Sadly no, I need to make time!

@BMS Any update on W213 E63S map development/dynos?

We've done a few E63S now with good feedback, but no dyno numbers yet on them.

I am wishing you would install it soon so I can decide JB4 or Dinan. I’m ready for this mod.

i fail to understand how there has been no dyno for a c63s since forever

I think it was said earlier that the numbers are the same as a C63.

is it possible to add extra burbles + crackles with this to the 2019 C63s?

Yes, but many of us simply want to see a graph of before and after. I want to see the delta on an S all along the rpm band. It shouldn’t be that crazy of an ask, given that I’m sure the majority of the customer
cars are/will be S’s. I really don’t think the reason it
hasn't been done is that it will appear disappointing, but it would be good to see nonetheless.
