Hi guys,

I have a 335i E92 for 6 years now with the JB4 installed since 5 years. The car is still in very good conditions and never had any trouble with it except a Lambda sensor that had to be replaced. I also installed proactively Index 12 injectors 2 years ago.

It is currently in Stage 2 with BMW Performance exhaust and a Wagner intercooler. I am using mainly Map 2 with SP98. From time to time and mainly just after the engine has warmed up, after WOT (just after I release the throttle) the blinkers light are flashing and the JB4 goes in rescue mode MAP4. I do not have any codes in the DME.

Can this be related to menu 10 or 12 settings? To me it looks like the boost pressure continues to be too high for half a second after I release the throttle caudsing the JB4 to switch in MAP 4 after overboost detection, I might be wrong but any insight from you is appreciated :-)

Thanks,
Tom

Trans temp is broken for me too with both 32_14_T11 and 32_15_T1. I just installed JB4 on my 08 E92 335xi and couldn't find 32_12 available for download.

Any idea why the filenames for my logs changed format? It seems like they still refer to dates, but not the correct dates.

Hello new Jb4 n54 user. I have been looking and can not find the updated steering wheel controll map for latest stable firmware. Found a few on this thread but they are all old.

Thanks

The one in the first post should be accurate?

For those running meth + flex fuel sensor, I've opened up an extra input on the small 9 pin connector, spot 8, formerly where the clutch wire went that is no longer needed. This new input can be used for flex fuel input with a firmware update. Just email me if you need it and we will include that change in the next public firmware release.

Hey, owned my 335i for a couple of months now FBO, recently changed the injectors to index 12's 800 miles ago running mhd stage 2. Yesterday I fitted jb4 followed the instructions perfectly, took the car out today and in every gear it hesitates really bad like there is zero boost running the pump tune bef map 5 changed to map 1 and then 2 both doing the same thing definitely noticeable in 6th there is zero power (manual btw) , changed back to mhd stage 2 and it's better but at some points it feels like the car misses slightly then continues to climb the revs, never done this before hand. Also sounds like the bov is open constantly with the jb4? The car isn't throwing any codes either.

I have had high battery drain since I installed the JB4. I am on firmware 14. I have heard that many people have flashed to firmware 12 and that solved their problem. My problem is I can't find the firmware 12. The link that is included in the thread shows only 14 and 15.

Is there somewhere I can find firmware 12?

Hey guys, just wondering if the exhaust flap can be open / close with the procedure shown below with a 08 135i, i can’t manage to have this method work, i’m able to control the flap in the jb4 menu but not the with the flasher method

Is it suppose to work or is it for newer car only?

Toggle between flap open, flap closed, and OEM operation, by pressing the button for 2 seconds and letting go. The left blinker will flash for valve open, right blinker for valve closed, and both blinkers for OEM operation. The valve setting is persistent and will remain in effect until you change it. If you hold the button too long you'll jump in to the in dash menu system below

Sorry this is a bit off topic guys, but I need some quick information to make sure I'm not buying an unusable JB4.
If a JB4 G5 for N54 has a Single Turbo firmware already, can you flash it back to a twin turbo firmware? Is it as easy as a normal firmware upload? Is there any reason I should NOT buy a used JB4 with a single turbo firmware???? Thanks!

Hope I can clarify a little.

JB4-

Here you dont flash specific Single turbo or hybrid firmware. You just update the firmware for the JB4 to the latest version. If you ar buying used you must manualy return all settings to default. If not your carr will probably not run o run very badly. How you update is through the app or with PC cable ... have a look at the stikies in this forum it is all explained you just need to read through. Same with default settings.

Your cars ECU MSD80/81

If you have a JB4 and would like to flash BEF (Back end Flash) either OTS ( off the shelf) map or custom map. You can do this and it is recomended and required for some features. Here you will be flashing your cars ECU not the JB4. For a BEF you can do it many ways the easiest is using MHD app and wifi dongle. The BEF maps for JB4 are free ... read throught the BEF thread. You must purchase the MHD BEF license (USD79 or something like that)

Anyhoo .... all this is reversable. Either your Jb4s firmware level or your ECU flash.

When you say I must manually return all features to default, you mean though the app, correct? And you only get the app by paying for it on your phones apps site, correct?
Thanks for the explanation. I truly appreciate it.

Correct if you ar purchasing a used Jb4 you will need to enter the configuration either throught the Jb4 app or throught the cable and change the settings to the default by hand.

Have a look here at post #3 and #4 for default values.

Okay, so I have installed the JB4 with a BT wireless connector today. Using the app, I updated my firmware to 32/15/2. However, I have questions about manually changing settings back to default. So I looked on post three to see all the default values. After first changing all settings to the default settings in that post, I then pushed them to Terry's settings listed in the "hybrid turbo" thread, and the car is quite a bit sharper now, and running much smoother. However, I am STILL getting the half engine warning whenever I start my car. So I am wondering if I haven't loaded something correctly, or what to check on why I am still getting the reduced power engine warning every time I start my car??? When I look for codes, there are none.

I for sure need to change something, as my car is continuing to give me a half engine warning that the engine has reduced power, when I crank it. On the other hand the car is quite a bit more responsive, and running pretty well while driving. And the check engine light goes away while I'm driving. Previously when I checked codes after driving it for a while, it said there were no codes. But I just now checked it again, right after starting, and it listed two codes. The first one is 2ABD intake pressure sensor. Which after researching says to check if tmap sensor was disconnected or a blown off pipe. Neither is the case in my car. The second code is 2DED Power Management, Standby current control. This is about disconnecting the battery. So I'm not sure what's going on there. I cleared both and they didn't come back after driving. I will research these codes more, but in the mean time, any help from Terry or anyone else who is willing to supply some answers would be much appreciated. I don't feel like it's off by much, as it drives very well right now, and as I said is very responsive. LPFP stays in the high 60's and lower 70's, and the HPFP stays around 12-13 on high boost.

I will add a couple of logs to the support forum. Thanks.

Post up a log and lets check your settings. Sounds like TMAP is set wrong. If you have factory TMAP make sure TMAP is set to 0 in app.

I am guessing you meant for me to post up a log in the Support and Log review section, so I deleted all the posts here, and made a new thread in the Support and Log Review section with new relevant logs. Please take a look at that thread, and let me know what I need to do next. Thanks.
