Firmware 11.7 isnt working por my 320i B48. Log attached.
First run after installing firmware 11 was ok, map 6, 17 flat psi, same settings as with firmware 9. Next day i did a log and the attached file is the result, ver y little if any extra boost. Tried additive Maps 1 to 3, they did make more boost than absolute map 6 with flat 17 psi but to much overall hessitation. Went again to firmware 9, map 6 and its working almost fine.
Hope you can enhance it soon.

Hi all... Im not sure if anyone else can help with this question, or if Terry would be the only one to answer. If you have any input please feel free to kindly respond...kindly....lol. I have one of the original B58 JB4 BETAs from early 2016. I am getting rid of my 340i - 6 speed manual...and getting a 2019 540i auto. i am currently running MAP 2..i have the BMS intake that i will try to swap over as well...my question is can i simply install the old unit, plug and play as is....or do i need to do any firmware changes to the JB4? Also, i havent really messed with it or changed any settings or firmware since i got it. Anything glaringly new i should be aware of? i am all about doing my research but there are way too many pages and way too many posts to run through them all. Any assistance, guidance or suggestions would be greatly appreciated. Thanks in advance

Let's see the same log on the v9 firmware so I can compare the two, see what is different.

Should swap right over! Short of that without seeing a JB4 log I can't tell tell what you have or what differences the new firmware might make for you.

Looks like it's something specific to the low boost target of the 320i and the new absolute logic, so just run the previous version if that works better for your particular situation.

LOL, issues with low DME on your car, and issue with high DME on my car, I hope they get this updated soon

I have 22 psi DME target on stage 2 flash tune, and the boost and WGDB control on pretty much all FW version does not work at all

here to hope they can support some level of boost control on flash tunes soon, this is an expensive meth controller

Noticed we were up to 11_T4 now... any changes from T1 to be aware of? I'm going to send in some Map 7 (meth + FF/EWG) logs. Map 7 feels very different on 11 than on 9.

Terry, any updates on when an update will be available for cars with digital gauge? The JB4 mobile app doesn't have feature for can flap.

I notice on some logs people have bit6 inputed in future use D. What exactly does this do? it shows ‘unused’ on the first page.

Indicates to the JB4 you have a flash map loaded, not used for a lot right not but some minor changes. Like map1 becomes the flash only map.

With FUA 10 it's also a little better but that is at the price of some boost. I did connect the EWG and FF wires for use with meth and while there was some improvement, the hesitation is not cured. It's much worse now that the weather is cold too (I had always suspected IAT/air temp had some relationship, even in summer). I have never been able to fully make it go away; I do hope that when the BEFs are available it may help. Who knows, though. So the idea was to send in some logs to see if there's a correlation with what happened between v9 and v11 which may point to the reason. I'm not the only dude with an M240i on meth, but I am not sure anyone else has this issue. Anyway I owe the logs, but weather does not always cooperate in winter. I'll send some in shortly.
Hopefully the BEF helps. I canít hit target boost only issue Iím having with MAP7.

Please share your logs when you get a chance.

The second 2 logs are short runs too (it was raining) but you can see with additive 30 and FUA 10, the hesitation is much improved - but overall power numbers are down. Peak boost targets in the 17-18 range.

All of these are with 93 octane and FF/EWG. I have also tried mixing in ethanol (got to around E18) and it might have actually made it worse... so I do not think this is an octane issue, but I could be wrong.

Just seems like the car is trying to get to some high boost number, but even with the meth, if it gets anywhere near 19-20 the throttle closes right away.

EDIT: Went back and read the latest posts from Terry and dRDiesel on the long B58 meth thread. Guess I should mention my car does not have a flash yet, so the internal fuel limiter was something I had considered. But I have read accounts of people making high levels of power with this engine on meth, even without the flash, so I wasn't sure this was what I was up against.

I went 1 firmware older i believe the the OBD2_9_T7 just for testing purposes and my target looks a lot closer then the latest firmware and logs.

Anyone notice switching from additive to absolute map quiets down the tone of your exhaust? Map 5 sounded mean now I feel like I need a dinan mid pipe after switching to map 7 my MPE doesn’t sound as aggressive and poppy.

Really weird because on map7 my car burbles and pops WAY more than on any other map. Could just be the ********* pipe but with map 7 it sounds like my car is cracking a whip.

Hi Guys ,

I`m just switch from jb+ to Jb4 (Metal case with bluetooth module) today on my X3m40i
It`s seem like the jb4 doesnt seem to give any additional boost as compare to jb+ which is straightforward.
Tried map 1 & 2 so far.
Tried updated firmware to 11._test4.hex still the same.
Able advise , am using Oct 95 , stock air filter with jb4
Issit safe to switch to map 3 ?
