Just swapped from a '15 F30 340i to a '17 C63S, had the JB4 in the 340i and absolutely loved it. Looking forward to staying in the BMS family if we can get the JB4 for the C63S.
Question - will this JB4 have the same in dash controls as the BMW B58 variant versions?

On the in dash controls the short answer is eventually. I have a good lead on the cash commands but have not cracked them yet. So plan on using the JB4 mobile app in the mean time for map changes and the sort.

We won't have a package per say due to our every day low price business model but after tune intake is a great bang for the buck modification. And the more boost you run the more of a benefit the intake provides. They go very well together.

Why so much discounting on these tunes and apps? Seems to me that a program that will improve the performance of an expensive vehicle by a significant amount ought to command a higher price tag. Then maybe the manufacturer can afford a warranty and in turn more people would be willing to upgrade their cars with the reassurance that a major mechanical event will be covered.

People in the know understand that these warranties offered from tuners only go so far. If you throw a rod through your block, I can almost guarantee you they won't be cutting you a check for $30k.

Please don't complain about a product being priced well... I'm sure BMS would be willing to sell you a JB4 for 3x more if you request it.

Dinan is also now owned by Driven Performance Brands, the same company that now owns APR, Flowmaster, Hurst, B&M, and Holley. Those are some of the biggest names in the aftermarket.

Dinan is an exception as their entire business model revolves around their factory matching drivetrain warranty. They've also been around for nearly four decades, so they're not some fly-by-night tuner that's going to close up shop when someone submits a warranty claim.

Now if you go make a custom map, requesting 10psi over stock in 30C weather, then I would start reaching out to someone in the dark net ahead of time to check if they can come and steal your car and then report theft. With a blown engine though, even that won't be easy.

Yeah and n54s don't fail due to jb4 lol.... I had a big turbo 135i before this, 30 psi on a stock block for over a year and never had any issue... But we're talking about an econoblock bmw engine vs a fully built hand built AMG block. There's plenty of m177s that have been making over 800+ whp and I'm assuming that's 25+ psi. Yalls stock turbo catted downpipes cars won't ever see over 20psi. You'll be fine

Jb4 doesn't touch timing or fuel maps. I'm pretty sure the ECU figures it out based off boost requested

I was referring to the Bimmer side, as that is a very mature platform for piggies and there's lots of reference points there. There have been blown N54 motors on a JB4 (and other piggies). It is certainly open to debate the root cause, but this is not the thread or forum for that. As Munis noted, if someone who doesn't know what they are doing were to start playing with settings of this or any piggy, there is a chance for catastrophic engine failure. As for your 135, if you were running 35psi on a 135i, then you had meth injection and/or E85, plus likely an aux fuel pump and maybe even aux port injection. A proper set-up and a knowledgeable user make a big difference.
