Default New on JB4, questions regarding boost and AFR - 05-24-2017, 01:01 PM

Yesterday i fitted a JB4 on my M135I with EWG, the car also had the BMS Intake kit installed today.
I did some runs today and i noticed that after fitting the BMS intake the JB4 seems to pull all the way up to 16psi on map 1, is this kind of boost levels considerd to be safe really?
The car is also running RON 93 (98 octane).
With the stock airbox it usually just went up to 12,5psi.
I have only connected the MAP and TMAP sensors as the instructions state, however i have the EWG harness aswell but i did not connect it to this point.

On map 5 it stops around 13,5psi with both stock airbox and BMS intake.
Would i need to keep an eye on the AFR, even when just running map 1 or should the JB4 and cars ECU manage to do this?
The car was around 15-16psi of boost from 2400rpm to about 3200rpm, just did a short pull.
At the same time the AFR was around 14,5-14,9 which to me sound a bit to lean?

Also is there any guide on how to operate the steering wheel settings on a F-series JB4?
I want to adjust the boost threshold on lower gears (running an 8-speed ZF).

Doing a quick glance boost levels look normal to me. Your stock boost is hitting 11psi, map1 requests around 4psi over stock.

As to why you're making 11psi stock, normally it's cars with the PPK package. But maybe just older software, higher intake temps, etc.

Fuel trims seem in check to me. I would update to the latest JB4 software though.

Thanks for your reply!

Is there any guide somewhere around here that explains how to update the software?
Would you consider it to be safe to run map 1 when looking at my map 1 logs for 3 and 5th gear?
Before i fitted the JB4 and BMS intake i was just hitting around 9psi of boost, when logging with a OBD reader.

How come stage 1 offers more boost than map 5?

Okay i did find a guide on how to update the software.
But should i go for the _11 version or _11_T12 for my EWG car?

Also some advice on which settings i should run according to my previous post would be appreciated.

Downloaded and updated it to the latest version today!

Today i also connected the FF harness, which caused something strange..
When coasting, 0 throttle, the AFR usually first drop and then increases until it has hit 3.8, then it stays there.
Any ideas on why?

I also noticed that the ign is being pushed back every now and then on WOT, decreased or constantly at 0.
Which according to the "instructions" (http://www.n54tech.com/forums/showthread.php?t=21269) means knocking is happening, even though i'm just running map 1.
Any ideas on how to prevent engine damage and get around the knocking?

Okay here is another log.
Running E15 now and went for some runs with map 5.
Before these runs i had been driving around for about 30mins and going WOT several times letting the JB4 adapt.

Some things concern me:
1. The ignition seems to drop severly on some occations, from like 6 to 0
2. I can only see the ignition on cyl 1 and 5
3. Mostly the boost is quite alot below target

Any other observations or advice?

I just realised that i did have ign-logging in the first log, with the old software.
However i lost it and now only have on cyl 1 and 5 with the new software.
Why was this removed and how do i get access to it again?

What changes were made from the software i was running from the begining to the new version?
If nothing major was changed i would rather roll back to software to the old version, just to get ignition loging on all cylinders.

Your latest log looks pretty normal, need to see a good 3rd gear pull from 2k to 6K+.

As for 6cyl timing...not sure, maybe a DME rom version incompatibility issue?

Thanks for your feedback!
I will get you a full 3rd gear pull 2k to 6k+.

Do you hae any comments on fuelling, the E-mixture that im running?
Do you think it would be possible to increase it slightly?

I'm trying to understand all the values myself and the meaning of the log.
From what i understand the fuel trims seems to be OK, however the fp_h is close to maxing out, is this something to be worried about or am safe to increase the E-content slightly?
From E15 to about E20-E25?

Last question, would recommend that i stick with the newest software or switch back to a older software that allows me to keep track of all the cylinders ignitions?

You can enable 6cyl timing logging via FUD options when you're connected to the car pls enable this.

You can change FOL to 60 (its currently at 50).
Map5 should take 3-5 WOT pulls 3rd gear 30mph to 100mph would be nice if you can.
Your FP_H looks fine, when your pedal is 100 FP_H should be no less than 12
Newest firmware works best

What do i set it to or are there any specific procedure to enable it?
It tried setting it from 0-6 in the Android app, without any change.

I have now adjusted the FOL to 60.
Tried to make a pull from about 30mph to about 80-90mph on 4th gear since im running the ZF 8speed and it had been raining earlier so i were struggling for traction..
Please let me know what you think.
Would it be OK to increase the E to about 20-25?
Currently running about E15.

You need to go to Settings > User Adjustments > go down to FUD and enable 6cyl timing you will see it. + Save

Finish your tank of whatever you currently have, next refill you can do E20-E25.
Are you testing the E85 before you add to your tank ? You want to see with a ethanol tester what content it has so you can know what you're adding and having a good measurement.

Yes i can see it and it allows me to set a value of 0-6, see attached image.

Ok I will try that.
No I'm not testing the fuel before refilling, but the e85 in Sweden contains 85% ethanol during summers and about 76% during winters.
However this car will only be used during summers.
I just did some reading up on E85 in Sweden and orderd a E85- test kit..

What did you think of the log?

See attached image of 6cyl ignition settings. Not connected ATM, that's why it's blacked out

Can't attach it since it's to large..
But it says "6cyl timing logging (0-6)
I8aos - 4, IJEOS - 5"

Connected the ewg harness today and now the car seems to achieve the targeted boost better.
Had done about 5-10 wot and 30min of driving before the log.
Fol is now set to 60 as adviced.
It seems to peak around 17psi, which sounds a bit high for just E15 and BMS intake as mods?

Any other opinions or does it look ok?

Timing looks okay but lower FF to 100 and do a couple logs. If boost continues to oscillate, lower PID to 8.

Thanks Steve!
I did adjust it to 100 and the boost seems to be more stable now and barely overshoots target with 0,2-0,3.
I ordered ******** and ic yesterday so I will post more logs when the new things have been mounted in about 1-2weeks.

A few questions appeared today since I'm planning to do some track days in the near future.
What map would you recommend for a track day?
Let's say that I'm running e20, ***** ********, upgraded ic, BMS intake kit and I want a OK map but don't need maximum power.

Also If i run e20 and the mods mentioned above, can I still run map 1 or 4?
Does the car's ECU adapt for the mods and e20 or am I risking some potential engine damage?
Or should I always use map 5 when running a ethanol mix?

Map 5 looked okay but I'd probably run a fixed boost map with safe boost targets for the track.

You can run maps 1, 4, 5 on E20. If the logs look okay you can also run map 2 or you always have the option to run map 6 with the appropriate boost targets for the fuel and mods you are running.

Thanks Steve!
Do you have some advice on where I should start as in building a map 6 for track use?
As I mentioned earlier the car will have a larger ic and ***** ******** fitted within a week.

Okay, today i set up a map 6 according to this post --> http://www.babybmw.net/forum/viewtop...=71029#p900203

Then did some driving and recorded 3 logs, 2 on 3rd gear and the last log on 4th gear.
Refueld just before and are now running about E22.
Any opinions on the logs and also the setup for map 6?
I still have not fitted the IC or de c@t, that will be fitted in the weekend.

1st and 2nd gear boost limits are pretty low.

15psi looks pretty good. I'd try some multi-gear pulls and see how it does before committing to that for track use. Are we talking road course or drag strip?
