Tried new firmware today. Mini_b38_B48_7_T1.hex Am able to read codes fine. Was not able to clear them. But, have not gotten the Invalid response now with new revision. Also noticed. Could not use Dash control for JB4. While App is connected to module. Disconnected app then dash controls worked. Could not clear codes with Dash control also.

Hi Terry,

Thanks for the email response last night on the 3rd Pair of Connectors. I tested the system out and Map 1 seems to run well without any issues. For Map 2 I had some lean detonation that I captured in this log.

You will see it was right after 4th gear upshift and the AFR climbed to ~17

Default Map Reverts to Valet Mode - 05-13-2021, 07:14 AM

Since the new app update, the current map has automatically changed to #8/valet mode many times. It has happened while driving.
Is it a bug or a safety feature?

APP Build: A347
Firmware Version 58/19//5

The other Updates in the app are great, having the details show for the Maps is awesome. Great Work on that.

Steve,
Here is a Log showing the Switch to Map 8

It appears that the boost pressure exceeded the safe max.

Start your own support thread and upload a log on map 1 for review.

totally agree...

BM3 now supports MINI F56! Will we see any back end flashes?

Terry,

On firmware 7, map 4 has been removed. Which map do we now use purely for logging and secondly does meth flow on map 0 when JB4 is disabled with meth trigger set to 1?

Is it possible to reinstate the map 4 as a logging map as that map allowed logging. It also seems the app does not upload older saved hex files to update/ downgrade firmware?

Downgrading is weird.
You need to email the hex to yourself, yes downloading online isnít the same.
Then you can ďopen in JB4 appĒ with the share button.

I used an older firmware 6_2 and map4 has been removed on it too. So my question is does meth flow on map 0 when you disable JB4 on firmware 7?

What map is suggested/recommended for the following:
- 2019 MINI Cooper JCW (manual hatchback, US)
- no known/visible modifications
- 93
- Texas heat

I purchased a JCW last week and decided to remain loyal to the JB4 unit after having a great experience using them on two 2019 GTIs.
https://burgertuning.com/products/mini-b38-b48-jb4

Been searching for JCW specific JB4 info/results without much luck and watched the development dyno threads/videos which mentioned upcoming 91 and possibly 93 dyno results but it appears the topic died long ago.
New JCW F56 Dyno - N54Tech.com - International Turbo Racing Discussion
1. What are the gains for the JCW?
2. What modifications and octane are required for each map? (colder plugs, 91, clutch, etc.)

Detailed information was provided for our GTIs (Gen3 VAG Group topic) however is absent for this platform. For example:

Map 2: Tuned map with 5.0psi peak boost over stock. 93AKI/98Ron recommended
Thanks!

Also could not help but notice the same. Seems like things came to a stop after 2015 for this platform. Nothing like the support/development for our GTIs. Chose JB4 over RaceChip, Dinan, NM, etc for my recently purchased JCW and question if that was a mistake after reviewing topics/responses for this platform.... VAG is night/day compared to this.

Dude I have had problems with Recent firmware releases and contacted customer service and donít even get a reply unless I really pester them, even then I get a one liner back saying they are looking into it.

I have also had months of trying to get water methanol to work with the JB4 on map 3, BMS are all happy saying it works great and will flog you the equipment but after that your on your own. Most up to date install instructions are from 2017 and the settings recommended do not work.

I contacted customer services and went into detail about the install and all I got back was update firmware and use map3 which I had already described as being done in my email. Honestly they canít even be bothered to read the emails.

The other platforms seem to get much better support and more up to date firmware that actually works, the B48 platform is neglected without a doubt and as soon as I find a solution to an alternative fail safe for my WMI install Iíll dump the JB4.

Iíve spent well over £1k on BMS products over the past 2 years and feel itís money wasted.

That is very unfortunate especially after seeing many members offer their cars to the development of this JB4 platform over the last 5+years. I saw your topic earlier.

Everyone seems to have remained very freindly and patient since 2015... and by no means are any of us bashing BMS, their JB units, etc. My wife and I love our GTI JB4s. This is merely observations, feedback, and personal experiences.

No single platform and its members should get any less attention or be treated any differently by BMS just because it sits at another table. Every JB4 platform should have the same level of support and development, especially if they are still being advertised/sold.

Well, I submitted a return request with approval and want to share the following reason/comment for transparentcy in hopes of someone changing my mind, especially when I am losing what I assume will be $100+ due to 20% restocking fees for something I haven't unboxed yet.

In no way am I trying to attack BMS, imply JB4 or "piggybacks" suck, etc. I have had nothing but great experiences with JB+ and JB4 on other platforms.
If I had bad intentions I would not share the following.
Quote:
Reason/Comment:
After delivery I reviewed the dedicated threads/section linked on product page to find/observe a lack of performance data, information, and recommendations/requirements that are provided to members/customers on other platforms, JB4 for Gen3 VAG Group for example, which we have and are very pleased with.
Many questions for the supported platform are left unanswered, mine included, and development/support for the B38/B46/B48/B58 platform appears to have been minimal after 2015 leaving only a few Maps with no mention of octane requirements or usage. A response in the thread stated JCW is supported but did not go into detail.
Please provide quality development and support for this platform or simply discontinue the MINI B38/B46/B48/B58 JB4 Tuner.
This was the response.
Quote:
Not a problem, the JB4 is really popular with the B-series Mini crowd, so we won't discontinue, but you can return, no problem.
So I must be missing or overlooking something because I have reviewed this sections threads, read the discussions, had my own question go unanswered, and searched all over for information and dyno results with little to no luck.

None of what I observed here for B-series Mini resembles our experience on the VAG side of JB4, which we use on two 2019 GTIs, and has left both my wife and I questioning why take risks advertising and selling JB4 for this Mini platform given its ongoing state of support/development compared to other JB4 platforms. To my surprise, I have read many users have or plan to remove JB4s from their Minis around the web because of the above mentioned... which I find unfortunate considering our positive experiences with JB modules.

Before I set out return the JB4 today - what did I miss???


This is the question I have asked that went unanswered.

I could still use a recommendation for the above (unanswered) to be safe.

Thanks!

Terry,
would you please update the first post to reflect your/BMS's findings for each Map to provide more clarity for current/future users.

Thanks!

For example:
MINI JB4 B38/B48 Map Guide:
Map#: psi peak over stock, supported vehicles, required mods, (recommended octanes)

"Map1: 4psi peak over stock. Supports B38/B48 S/JCW. Suitable for stock vehicles. (This is the shipped map and is compatible with both 91 and 93 octane)"
