Boost response yes. If you're looking to change the pedal to torque relationship to be more aggressive than "sport" mode check out our pedal tuner.

any plans on an intake system for the M550i?

ps JB4 getting installed Friday morning, super excited to feel difference.

Terry @ BMS 01-23-2019 12:48 PM

We haven't looked in to an intake yet on the M550, we explored it on the previous 550 but ultimately decided the market wasn't there to justify the costs of making it.

Tsela_f80 01-25-2019 01:22 PM

just had the jb4 installed.

car feels good, boost response is improved. ill do some logs after a few more miles and its adapted.

Terry question the techs did not connect the EWG sensors to the jb4. this shouldnt have any negative affects?

Terry @ BMS 01-25-2019 02:15 PM

We haven't really done the R&D for those yet on the N63TU, just left them on the harness for future upgrade. So they did the right thing leaving them off for now. :)

Question terry,

What’s the difference between map 2 & 3/5?

I know one says Additive and the other is absolute but what does that even mean? Haha

Which one would produce most boost/power?

And is it safe to run?

Thanks in advance

Terry @ BMS 01-26-2019 10:27 PM

Additive maps are adding boost to the stock profile, while absolute maps are targeting a fixed profile via the JB4 mapping regardless of what the ECU is asking for. Both have their advantages. Grab a log on map3, another on map2, and lets compare them for your situation.

Hey Terry,

here are a couple map 2 & 3 Logs.

Let me know what you think

Any word on Compatibility for N63TU3, sorry if it has been answered. Friend of mine has the 2019 X5

Terry @ BMS 01-29-2019 05:51 PM

From what we've tested so far it's all good to go.

Looks as expected so far. Want to experiment with the EWG connections? :drinking:

What would connecting the EWG do exactly?

Terry @ BMS 01-30-2019 05:31 PM

Allow the JB4 to drive higher boost levels.

Tsela_f80 01-31-2019 02:12 PM

Is the similar to the f90 jb4?

I’d assume that has the EWG connected to be able reach those power levels.

Terry @ BMS 01-31-2019 05:46 PM

Yes, same as the F90 JB4 EWG connections.

Tsela_f80 02-01-2019 10:50 AM

not sure if i want to be a test mule on this haha

Terry @ BMS 02-01-2019 11:07 AM

Certainly your prerogative. If anyone with a G series is looking for more boost and wants to play around, they can always email us. :)

DJTones 02-02-2019 10:10 AM

Does any particular map allow for a more aggressive sounding exhaust?

Terry @ BMS 02-02-2019 11:48 AM

The exhaust changes with higher boost won't be dramatic, but it will be a little louder. :)

Terry, I just installed the JB4 on my 2019 M550i. Can you take a look at the logs running maps 2 & 3 and let me know your thoughts? Thank you!

Terry, what is your email?

Terry,

I'll be turning in my '16 M5 lease this summer and have a M550 on order. Would I be able to use the JB4 hardware from my M5 on the M550?

Terry @ BMS 02-10-2019 12:32 PM

The M550 uses a different harness that is EWG based, so best to sell that one and buy the correct one for the new ride! You're going to love the AWD. :)
