The JB4 is fully plug and play and unlike Dinan offers fuel control and CANbus. As well as optional boost solenoid control for those really looking to push things. There are maybe 200 C63s tuned with JB4 now and working well.
When people have issues with their car we're always here to provide advice and support as we're doing in this support thread! If you don't want to hear about issues and their resolution don't hang out in support threads.
200 c63s and not one before and after dyno? No feed back? Logs? Something? Am I in the wrong forum? I even checked N54 tech. Nothing there either.
Great! I bought my JB4 last week anyway. I just have not installed it yet. I had it on my 2014 335i for 5 years without a hitch and really had a great experience with the product, Terry and the entire crew over there at Burger tuning. That's the reason I bought it since there is no data for C63s..lol..but I have faith..lol. I plan on doing a before and after dyno run too just wont be for another couple weeks as I am going on vacation. Hopefully, you'll publish your results before then. Cheers.

My thoughts exactly. And my JB4 sits in its box as well until I gain some confidence in what I’m seeing (or lack thereof). I also had a flawless (JB3) 335i experience with Terry and crew back in the day.
Anyway, BMS, would it be feasible to roll out included maps that are called “Map 1 BR”, “Map 2 BR”, etc which have the standard appropriate map settings, but already have solid starting values in place for boost reduction in lower gears, based on experience with stock wheels and tires? This would be one more thing to really letting the JB4 be plug and play.
Here's a little teaser of our meth kit setup. Our 2 gallon kit fits perfectly under the cowls, no need to run wires or lines in through the car.
This meth kit took about 30 minutes to install Will have some dyno numbers posted soon.
Is the battery relocated for the meth kit? Looking at mine now.
You can have friends or relatives live in other states order for ... ?? 😀
It amazes me that people who presumably are intelligent enough have a career that supports buying a car like this need instructions on how to get a part. 😂

You never know. It could be someone work for the GOV trying to bait and hook? 😀
Ordered it today for Father’s Day! How much longer for the intakes?
I think a couple more weeks. I'm hoping to start shipping in the first week of July!
Busy race season, lots of things are delayed by some of our manufacturers.
Worth the wait, I promise!!
Is there any type of push notification or sign-up to receive alerts when new C63 JB4 firmware and/or maps are released? I know there’s a page on N54 but, like most people, life gets busy and remembering to check can really slip the mind.
Got the WMI kit, looking at the install manual it appears this mod will delete the air cabin filters. I am not sure I am OK with leaving that sitting wide open under the hood. Anyone else install one yet? What did you do?
