Default log review - 02-18-2019, 08:23 AM

I finally got around to putting my jb4 back in after seeing how the car was with out it and just the bolt ons. Please check logs and let me know if all looks clean.

I did not throw any codes or misfires upon trying to get a good pull today on road. multiple about 5 solid pulls but i believe this was the best of them

I feel like it definitely doesn't have the smoothness in map 1 as is does with no JB4 installed and again on the way home i put it in map 0 and the car seemed to behave exactly the same as map 1 which is why i took it out in the first place. ???????

I do have a cable now to BEF flash so insight on which BEF to put on would be great
thank you

Can you describe what you mean by smoothness? Are you referring to just cruising, WOT? Both?

Load the appropriate BEF for your modifications/ fuel- & lets re-log. That usually really helps with consistency & overall

Boost looks decent, timing ok as well.

Trims / AFR need a bit of work- all of that usually is smoothed &
Fixed with the BEF.

So after pulling out of the gas station aggressively 1-2-3 all seemed good then i decided to check the map for fun and i was in map 4 for some reason and i know i was in map 1 so it kicked me out. So i put the car in map 0 to see drive ability and to see if i could see a difference well i started gettin the surging again (notice in map 0 i hit 15psi boost ) and didnt drive like i had no JB4 installed. So i logged just driving here are those logs

also i did a log just getting on it not flooring it but getting on it on the on ramp to highway and i got thrown in to limp mode

30fe
3100 are the cause

keep in mind i recently took the jb4 out and drove for almost a month with no issues at all no codes other then ******* ********* detected codes. drive ability was great not a hiccup at all

if you guys have any insight im all ears because I honestly feel there is something wrong with this JB4 unit

its set to 2600 i lowered it the other day

however keep in mind this happened in map 0. From what i understand JB4 should not have any effect on the car in map 0 ?

I honestly think something is wrong with this unit since when it is removed car runs flawless

It can happen in map 0 too...

Try setting menu 12 to about 1500 rpm

I have lowered it it 1500 running in map 1 judging by the boost gauge it doesnt seem to be pulling as much. I bumped it back to 2k and definitely see it pull some more. Drive ability seems ok. what does lowering this do for the car ?

Menu 12 sets your base duty bias - min duty cycle to your boost solenoids

i just did two pulls while out car was good it seemed
I have menu 12 @ 1500 for these
I did get a code pop up a little later while driviing for
29E1 Fuel mixture control 2 w/ the 29F4-5 as per usual

car doesn't Hit as hard as it did before while doing a log but again i assume that's because the boost isnt surging?

Your throwing that mixture control 2 code because your trims on bank 2 are maxing out.

Load the BEF. Should help with that & remember to set the JB4 to 4/2 after you flash the car

Since this will be my first BEF flas is this correct?

I have downloaded the Bimmer boost 2.0 program
i have downloaded the JB4_N54_BEF_020719.zip file
I have bought a BMW INPA/Ediabas K+DCAN USB Interface OBDII OBD2 Car Diagnostic Tool Cable

and i should be using the JB4_lJEOS_PUMP_USA.bin file for my car correct?

93 octane = pump flash, yes.

If you have an Android device- MHD + d can cable would make your life / flashing easier....

still haven't loaded a backend flash because with the JB4 installed and option 11 turned down to 1500 cars seems ok but does not boost great turn it back up to 2400 car acts stupid again i have been trying it at 1800 and 2000

tried a pull the other day in third and instant engine malfunction and thrown in map 4

tried again today same thing happened pull these codes twice
2C32
2AAF
2C28
2C6C
29E1

Since i have yet to find it what is default for JB4 settings delivered from you guys or how does one reset to factory this is getting frustrating considering even in map 0 the car will act up

JB4 removed car runs awesome JB4 installed mostly garbage unless option 11 is turned down way below the suggested setting then it drives well like normal

heres a log if it will help of being thrown in map 4 when i went for a pull in 3rd gear with DTC off

We’d need a description of the codes.

But your being thrown into map 4/ safety due to “2” or lean AFR.

I suspect you have an o2 sensor / hardware issue based on the log & the car acting up In “0”

Looking at all your settings via that log, your firmware looks up to date, your Fud/FUA settings look to be default, as does your tmap.

2C32 - Lambda probe in front of catalytic converter 2 trimming control
2AAF - Fuel pump Plausibility
2C28 - Lambda probe in front of catalytic converter 2 system check
2C6C - Lambda probe behind of catalytic converter 2 system check
29E1 - Fuel mixture control 2

I just replaced the front O2 sensors 1500 miles ago

i have not done the rear 02

I am going to ask this again map 0 means no JB4 installed correct. then why would it make the car act up

When JB4 is unplugged car is fine

Based on those codes- it appears you still have an o2 issue, front & rear. I’d inspect the O2s you just replaced for damage, not uncommon sadly to get some bad parts out the box (happened to me 2x with O2s)

Map 0 the JB4 is bypassed- but not fully disabled

i have ordered two rear o2's today

if i had a bad o2 in the front my afr's would be wacky

based on what you said before it was my trims and to load a backend flash

keep in mind with the JB4 i get zero codes ( except ******* ********* detected) what so ever so why is the JB4 causing issues when installed and still running map 0? I run map one all the time currently but like i said before as per your advice i turned option 12 down but the car generally feels stock.

pardon my ignorance here but every log i have shown in threads i get a different answer and no one seems to have an answer or advice other then keep throwing parts at the car which doesn't make sense

i did o2's as per someone else - no major difference but better gas mileage
plugs no difference
changed settings as per someone for the OL from 90 to 70 IIRC
load a BEF - haven't done that yet
changed option 12 down from 2400 to 1500 there is a great improvment but car doesnt feel as it did at 2400 ?

only thing that makes the car drive good is JB4 removed

I have read much on the JB4 and people who install it and have run great for years with no need for a BEF

With that said i did a small pull in third today and no engine malfunction

I am at a loss here im just looking for some solid advice from BMS as to the issue based on the logs i have but every log i feel like i get guesses in the wind. Based on the codes not the actual logs codes i can read and diagnose logs are new to me but owell

Sorry you feel that way- however you are asking for help / diagnose/ opinion on an Internet forum- you donít have to take the advice from us or any other members.

With that said codes & logs are the most accurate way for anyone to make educated recommendations. You are correct, plenty of people run JB4 only- however, users looking to get the most out of his or her setup, the natural progression is to stack/ run out tried & true BEF, and thatís not up for debate.

There is a bit of a learning curve with the JB4, imo it forces end users to get more familiar not only with the JB4, but their car in general.

There are plenty of solid members with years of n54 experience, besides us at BMS, granted every car is unique & reacts differently to modifications- a lot of that falls back on the general condition of the car- existing hardware issues are going to be exasperated by any tune.

If your frustrated & not overall happy with the diagnosis & help you are receiving - based on the codes you posted, you may want to take the car to a trusted shop & have them go over the hardware issues those codes are alluding / pointing towards.

Looking at what youíve already done, you havenít done the thing that is free- load the flash. The appropriate BEF helps with timing, afr & fuel.

Again sorry for your frustration, I wouldnít just throw $ at an issue, we (BMS / Fuel-it!) never recommend that, that ultimately is up to you as the end user.

If the car runs ďperfectĒ without the JB4- you could always remove it, car wonít be as fun, but it may be a little less stressful for you. Or, you can continue to troubleshoot, itís usually worth it & a lot of fun when everything gets sorted.

You mentioned if it was an o2 your AFR would be whacky- based on your most recent log / and the codes you have present- your AFRs are Whacky. You have a pretty large bank 1 to bank 2 variance - you get thrown to map 4, trigger safety 2 = AFR LEAN- if you look at AFR2 on the log you posted- you are at 17:1- thatís why you are triggering JB4 safety.

Cheers
