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?
