Terry.
BM3 supports B46/B48.
You think we can get some MINI Support and BEF for our cars?

Afternoon all. I've just (this minute) picked up a JB4 to use on my B48 Mini. I've done some reading and still a bit unsure on some things. The jb4 came off a B58 BMW M140i and although it has the bluetooth adaptor, does not have the computer attachment. So to install the correct firmware, I plug the JB4 in, link the app to my phone and install the firmware that way? I ask as I've seen some mention of the JB4 auto detects if it is connected to a B38/48/58 and sets the firmware automatically.
If I'm using the bluetooth does the OBD plug need to be in use or can I leave it disconnected? I'll be running map 1 initially until I'm sure all is ok then try map 2.

OBD is not needed. Yes install proper firmware on the first page of this thread with JB4 app and Bluetooth.

Car: 2017 Mini Countryman All4
Default BC No response / CEL on - 02-09-2020, 08:39 AM

What am I missing?

I installed a JB4 on my 2013 335i 2+ years ago and LOVE IT!

I attempted to install on my 2017 Mini Countryman S All 4... Attempted being the key word.

Has anyone else ran into this:

Problem: Installed and no response from BC button and the CEL comes on?

I contacted support (Ando replied) and after some diagnosis, I found that only one of the pins from the OBD connector was actually being fed into the 2 pins of the JB4. I provided pictures, explained the issue and was told to ship the cable and unit back ($14 no big deal).

Ando replied that a new unit was on its way. I asked what the issue was he said "replaced cable". I was skeptical because he also said that regardless of the cable, the unit should be defaulted to Map 1 and no CEL.

Received it this weekend, tested the new cable and confirmed that indeed 2 pins were now active from the OBD connector to JB4, so I installed it, started the car..... CEL and no BC button response!

It is the most simple thing to install, 2 connections at the engine, and one to the OBD... I am not an idiot and it really is fool proof...

I am patient because this is a performance upgrade, not a required part (luckily I have the tool to reset CEL). I really want this thing to work.

So what am I doing wrong? Am I the only one who ever encountered this?

If you're already working with Ando, best to keep the support in one place.

Hi,
What is the current status of B38 engine support for Minis?
I guess a compression ration of 11:1 is one of the main limiting factors in tuning this engine (with temperature at 11:1 CR being about 40 degrees C/100 Fahrenheit higher than at 9.5:1)? Will it be better to install 1-step colder spark plugs? Will RON 98 fuel be enough for ~180 hp map?

Anyway, 170-180 hp is good enough, but there is not much info about JB4 and B38 engine. Is it still actively supported by JB4 (seems to be, as listed here https://burgertuning.com/collections...ni-b38-b48-jb4 , but some posts in this thread made me fell uncertain)?

What factors other then boost pressure are modified by JB4 in a B38 engine?

Also what is the difference in gains and what are limitations when using JB+ box and is it suitable for B38 engine (Here https://burgertuning.com/collections...-install-tuner it is listed in "Applications", but not in a heading)

Both JB+ and JB4 tuning is supported for the B38! Gains vary based on fuel but around 15%. The JB4 provides a lot more features and tuning options than JB+ but at a higher cost with a little more install effort.

Hi,
today I got a used jb4 (x55 rev 3.0) for my 2015 F56 JCW.
Which firmware should I use? What are the differences between the two versions on first page?

I am new to jb4. Is there something I have to aware to?
Or just install it, select map 1 or 2 an drive? (my mini is stock)
