2009 335i xdrive auto (no tcu flash yet, but very soon) 80k miles

Shell v-power 92 Octane

2 injectors were bad (mix of index 7 and 9), and just put in a full set of index 12 today. New set of Bosch Double Platinum 1 step colder plugs gapped at .025 put in today as well. (Installed at 80k)

new waterpump, LPFP, and alternator installed 70k

(everything below installed around 35k miles)
jb4 running version 32/12//2 Map 5
6-Cyl timing doesn't seem enabled. I have been using I8A0S. (anyone know the right one for a 09/2009 335 n54?)
Stett charge pipe, BOV, DCI
7" FMIC


Outside temp: 72F
Humidity: 35ish%

It was hard to get a solid 3rd gear pull, but I have 2 here up towards 6k rpm. I think heatsoak started to set in as boost seemed to get a bit lower as the pulls kept going. Probably did 20-25 pulls total trying to get some solid ones in, and the 3rd gear logs are around the 20ish range.

The 2nd gear pull was an accident, but at least that one goes through most the rpm range (and was around the 5th pull total). This one shows boost hitting pretty steady in the 15s.

If these logs are no good due to 6cyl timing missing, please let me know, and which logging to use.

Thanks, I'll swap to #5 and try for a 3rd gear run tomorrow. Anyone able to tell if the LFPF is able to keep up from the current logs? It's brand new, but something seems a bit off. Have a feeling it may be the LPFP.

Anyways, I'll upload when I can get a solid 3rd gear pull.

Cheers.

Okay. Finally got "decent" runs in. Still couldn't hit redline, but at least 5600, 6300, and 6600, all 3rd gear pulls.

The two logs with the word at the end: bog, those are the pulls where it felt like the fuel pump was dying on me, but it recovered and kept pulling. I guess to compare the feeling when it was happening: when you have a bad plug, and it misfires constantly, and you try to do a map 2 3rd gear pull. It felt like that for just a few, and then kept going like normal. It doesn't happen very often, but it does maybe every couple of days. Hopefully these two bog logs will show something that I am not seeing.

The third log is a good solid 3rd gear pull where everything felt right and tight.

Thanks.

Don't see anything that is jumping out fuel pressure wise...

One thing that may help the overall performance / smoothness of the car would be utilizing our BEF

Thanks, Dave. Glad to see everything appears to be in good working order. Hopefully the BEF will solve those random bog downs.

I have an Android with MHD setup, connection tested, and ready to go. Will have to wait until we are done moving this week before I can do the BEF.

Just to confirm for when I do get to flashing:
1. Use MHD (per this link)
2. Change JB4 to map 0, and make sure I get the correct car version
3. Purchase custom map in MHD, and use the 02/07/19 Map Release BEF
4. Change jb4 to BEF compatibility

(side note: I will also be doing the tranny flash during this time as well.)

Thanks again for the review. After the move and I get the flashes done, I'll post one last log to close this out.

Dont need to purchase anything off MHD- SAVE YOUR $$$ ; )

You can download the appropriate & most up to date BEF here (BEF templates): N54 BimmerBoost MHD Back End Flash Maps - N54Tech.com - International Turbo Racing Discussion

After flash- set jb4 on your tach to 4/2- and throw up a log of map 1 or 2 for us to review

Finally got moved, and been testing stuff on the car.

1. BEF made the car run slow/sluggish. Flash was successful, selected the JB4_IJE0S_PUMP_USA.bin (running Shell vPower 92), everything looked good flash and settings wise, but the car felt all wrong. I checked that the jb4 menu 4/2 was saved. Question: When selecting to menu 4, it should automatically go to 2 if it was saved correctly? Before changing it was 4/4 (or 4/5. What is it suppose to be by default with no BEF?). With the BEF I had it set to 4/2 (providing I saved it correctly. I normally don't use the steering controls). Is there a way to see/set this setting in the jb4 PC app? or jb4 mobile? Either way, it felt like the turbos were disabled, and that power was around stock levels, or a little less (not as bad as limp mode, but similar feeling). Any ideas on this?

2. I now have the xHP stage 2 TCU flash, and I am happy with the shifting behavior now. Much improved.

3. The attached logs are both Map 5. The bog I experience happened during one of these two pulls (bog in the name). It wasn't as boggish as before, but still noticeable.

4. The normal log was a good pull, near redline, but what concerns me after looking at the log is the boost spike after the pull. I don't remember the car sounding or doing anything out of the normal. I let off the gas, and shifted to 4th as normal, BOV let out the pressure as normal.

5. Last thing to add on top of all of this. I got for the first time 30FC: Exhaust fume turbo charger, density. Not sure what this means. I've also had the car go into limp mode twice, with no codes displayed on the jb4, and the map stayed on 5. I have never seen this happen either.

Anyways. Please let me know your thoughts on some of this if you can, and what the logs look like. I'd really like to try and get the BEF sorted out for future changes.

Outside of some timing corrections, this log does not look to obad.

Based on your boost profile, you do look to be in 4/2 mode - so all good there.

Having the jb4 in the wrong tach setting will make it feel "disabled"

Clear the codes and see what comes back

I’ll see if I can get the BEF reflashed, and redo the logs. Thanks a ton.
