Default Log Review Request - 11-02-2019, 07:56 PM

Finally got a chance to log some pulls, been running JB4 for a several months now with no BEF as of yet. Current upgrades are as follows:

5" FMI
Charge Pipe w/ BOV
3" ******* *********

Everything is stock. DCI's on order, patiently awaiting their arrival.

Logged two pulls under Map5 & Map1. Prior to installing **'s JB4 would hold Map5, now it reverts to Map4 four out of five times. Review and recommendation would be greatly appreciated....Cheers

Did you say you installed C-A-T less down ***** ? (Not sure why it block out the word "***", but it does). Maybe you knocked an 02 sensor or something when you installed them?
Reason your being kicked into MAP4 I believe is this: Your AFR is really lean (In my opinion, reading 15-16 and should be down between 11.5 - 12.5 under a WOT load, more fuel, less air) and your Trims are often stuck all the way at max with a value of 50 and they should be closer to 25 +/- 10 or so. Therefore, the ECU see's this lean event after about 2 full seconds, tries to add more fuel to richen up the mixture but can't (when trims are all the way up to 50, it's maxed out with no more headroom) therefore it pulls timing, drops the target boost and in this case it took your target to 8 immediately and kicked you into stock settings, MAP4. You can also see the ECU attempt to close the throttle without you taking your foot off the pedal (see RPM 4,800 range roughly, there's a partial closure on uploaded MAP 5 _02.)

Did it throw any codes? I also am running without a BEF and am waiting for a new cable as my attempt to load one failed (cable died one minute in, wiped ECU data but couldn't write new data) and rendered my car dead until I can attempt to re-flash again. However, I've never had this issue your experiencing to this degree but when I did have a small amount of high trims, raising my FOL setting from 70 to 80 fixed it. But I would guess that since this only started once you changed your ***'s it might have something to do with an O2 sensor.

Please know I'm only giving advice and could be completely wrong, but based on what I've seen in responses from the pro's, they would point out your high (maxed) trims at 50 and a lean condition. You may be able to change your FOL setting higher than 90 which is where it was set when you posted the logs, but I think you need to reduce fuel demand by other means and getting a pump back end flash may get you sorted out.

I'd read this on N54 tech as it talks about some of what you're experiencing and how to make changes to fix the issue.

Hope it works out well. Enjoy the hell outta your car once BMS get's you sorted out. I know I will when mines back up and running!!

Yep c.a.t less down-p.i.p.e.s, not sure why it does that either, lol. But I definitely didn't damage the O2's...I actually replaced them with new ones since I would have them out.

As far as error codes go, it's been throwing a 29F3 since I got the car, but never triggered a service engine light (I'll be replacing the fuel pressure sensor and line when it arrives).

But since I installed the p.i.p.e.s it's now throwing a 29F4, 29F5 and 2DED. The 29F4/5 I get and I believe will be taken care of with a BEF, but the 2DED has me baffled.

That's strange. How long till you can do a BEF? Might get things settled ...

Looking to get one right away, as soon as I do some research on exactly what licenses I need to purchase.

Your trims max- / force you lean.

Hence the map 4 / safety throw.

I’d load the BEF that should help with the trims / afr issue

Ok. If I understand correctly it would it be the: JB4_I8A0S_PUMP_USA and not the JB4_I8A0S_PUMP file, correct?

I have a E90 335i with a manufacturer date of 07.2007.

I ended up loading the 'JB4_I8A0S_PUMP' file, and I could notice right away a smoother idle. Did a few pulls and this was the last one (w/ stock intake filter). AFR looks better and fuel trim didn't max out.

I'm having trouble since I loaded the JB4_I8A0S_PUMP_USA file and not the regular PUMP file. Figured the USA version was for gas specific in the states but maybe not. If I don't get sorted better tomorrow after Dave looks at my logs, I may just try the non USA file instead, can't hurt.

Your looking better for sure with that last log. Not so lean. However, enable 6-cyl timing in your JB4 setting. When looking at the log cyl 2-6 is blank, wasn't recorded. Once you do so, they'll want you to do another log. Figured I'd save you the time, if you can, do it tonight and repost it, they'll see it tomorrow morning you'd be a step further ahead in getting results.

Either way, looking better, that's a good sign your on your way. Curious if the USA file I loaded for the BEF was the right choice since I'm having timing/fueling issues now and it worked well for you......I may have to re-flash and take a midnight run for a new log now lol.

So coincidentally I did one more pull to make sure the auto-tune was dialed in, and the infamous misfire surfaced on cylinder #4. I replaced the plugs back in Dec. and I know I haven't put 5k miles on them yet. So I'm going to order some new coils and some 2-step colder plugs to be safe, and try it again once I get them all swapped out.

I'm also going to look into enabling the 6-cyl timing...I thought I mirrored all the settings from the JB4 sticky thread, but I'm going to triple check. Thanks for the recommendations!

Let car sit overnight & pull that plug if it’s wet it’s likely an injector.

When I saw your post, I was crap...those are gonna set me back, lol. But it made sense they would be the culprit, since I had just replace all coils and plugs, as well as cleaned the intake ports. And sure enough they were. Once I replaced the injectors, the misfire/rough idle during warm up went away...it's been crispy for the last several weeks. Thanks for you help.

That being said, I now have for sale a used set of Index-7 injectors, lol. Only one (cylinder 3) was a little leaky and would cause a misfire/rough idle during cold starts.

Default Single Turbo - 07-26-2020, 08:47 PM

Finally switch over to a single turbo setup (docrace 62mm).

Running 92/93 pump for now, so just looking to dial in the map 2 setting.

Logged two pulls today, map 2 feels fairly choppy tho, not sure why.

Seems like it's have a hard time trying to regulate boost...not sure.

I can go into more detail about my setup if need be.

But any help is greatly appreciated....cheers

So......I've upgraded the LPFP (FI-650HP ) and logged a couple pulls targeting 17psi. The first one was a bit choppy still, but I logged two additional pulls and by the third one it was noticeably smoother.

If it needs more pulls to smooth out the tune I'll happily to give it what it needs I installed a 3.5 TMAP sensor in the event I have enough fuel to support 20+psi.

But I'm attaching the first & third logs for review to make sure.

Thanks in advance, Cheers

Fueling looks good. I dont see mods (maybe because im on mobile), but if you turn it up....do it slowly. Dont know what fuel you are on.
