JB4 and JB+ are good products but man i wish i didn't have to ship my DME to FEMTO to have it unlocked.

I plan to do this install as well as down-pipe and intake pipe and box on my X5 45e

So I’ve seen other piggyback systems like the Dahler one that’s WAY more expensive, BUT it has a ton of hook ups and it’s own ECU that wires to power and runs multiple sensor data in real time. I feel like this version being SO simple has to be missing some crucial DME data and looks risky, right??

Ton of people are running this with the b58 its just bumping the boost

Exactly. No advanced tuning. If you want to go that route do the full JB4 module or the like from other manufacturers. I’ve been more than happy with this simple and inexpensive mod nearly 6 months later. I’ve had the JB4 module in other vehicles (video in my playlists). Burger makes a solid product and excellent customer service.

Wondering how it works with the 2023 model with mild hybrid system?

Is it more jerky in low gears and did you mess with the Jb plus dials?

@GoldenFleas 9 ай бұрын

Nope, no issues with gear change/transmission. Haven’t opened it up and adjusted the dial. Just straight from the box to install.

it was jerky on my supra in sport mode manual shifting when i was running 91 octane. But when i put 93, its buttery smooth.

Hey bro, I have a 2021 X3 M40i and just ordered a JB+ for it!! In the video I saw you installed it the way it came right out of the box!! After you made the video did you up the settings to max or just keep it the way it came!! I any case are you still happy with it!! Thx

@GoldenFleas 6 ай бұрын

Nope left it set out of the box. Obviously you can adjust but I’m good with it as is so far. Really enjoy it. Simple/inexpensive upgrade to squeeze a little more juice out.

I have a 2021 X3 M40i myself, just want to know if you did installed the JB+ what are the updates since the installation, any issues?

Looks way easier than the JB4 install. I'm waiting for the warranty on my X3M to expire before messing with anything but I had a JB4 on my MK7 Golf R and it was a HUGE improvement. FYI, BMW CAN see that the engine had a piggyback unit on there but unless you have major engine problems, they won't go poking around but it was confirmed by a few BMW techs on Reddit that they can see even tiny changes to boost pressure so it's not a matter of removing it before trying to get warranty work done and fooling them. Your car is constantly feeding telematics data back to BMW so before they even diagnose the problem, they can look back on the historical data from the car and see when it was making more boost than stock before you removed the piggy back unit. Coders are constantly trying to get around not just BMW's detection systems but several other brands' as well but BMW have a team dedicated to this and it's not hard for them to spot red flags when the vehicle is programmed for such tight tolerances. First time I brought my car in for service, they documented the RK intakes and aftermarket exhaust (factory cats still there) but they also scanned my ECU and pulled up the car's telematics data to verify that the ECU was still encrypted and that no parameters had readings outside the norms. I had no idea they did any of this until after the service when the lead tech came out to tell me that it was all documented per BMW's policies so that if anything DOES go wrong, they have that bread crumb trail to get them out of warranty work if I DO mess with the ECU. I got the uneasy impression that the tech was implying that they could still use intakes or a non-resonated mid pipe to still deny warranty work. I'm not here to fear monger or rain on your parade. I'm just passing along info that BMW has told me in case you do decide you want to push the engine further. I think a catted downpipe from AA and an intake would be the only other things I'd be comfortable doing if I were you until the warranty is up. They will know. They already know you're making more boost than stock but basically nothing can hurt the B58 as long as the factory turbo is left alone. Worst case scenario is just some crappy gear shifts.

Thanks for this feedback much appreciated! Have had the JB4 in the past also on other vehicles. Big improvement. This is much simpler/quicker install to get some pretty decent hp increases.
