Default Running lean, please help with guidance - 04-26-2021, 01:26 PM

I'm really hoping to get some expert help from you guys in here, cause I've got some serious performance issues with my 335i.
Got no idea if it's regarding to some wrong jb4 settings or something else wrong with the car, but I've attached a log from map 2, 5 & 6 and when hitting the pedal from 2000 rpm in 3rd gear to the metal, then I'm really quickly being thrown into map 4 from all maps.

Attached is my user adjustment screen (hybrid turbos) and WMI screen.

I'm running straight 100 ron octane in Denmark, which is around the 95 Pon US octane, no WMI or anything, but is there something I need to change at the WMI screen since I'm not using it?

"Meth Trigger Mode" has also been in 0 instead of the 3 on the picture, but no difference.

I've got the steering wheel setting 4/2 in place for BMS Flash and the 1 for the 3.5 bar Tmap sensor.

Crossing fingers and toes for some helpfull guidance from you, so that I can soon get into the car with a smile on the face again.

I'm not an expert, but it looks like your FOL (Fuel_OL) is too low at 40. Your Trims are maxing out. If you look at all your logs, you drop into Map 4 once your Trims have been running maxed out at 50. I think (again, not an expert) that raising your FOL will help.

What would you believe that I should adjust the fuel open loop to then? 60 and then do a new Logging?
How about all my settings regarding WMI, anything I need to change there since I'm not using it or is it already disabled with these settings I've got in the Jb4?

You are running way too lean and trims are maxed. You can bump your FOL up to 90 but I think you're beyond that.

You also have a bunch of weird settings...I'd suggest putting everything back to default settings and adjust the ones for your hybrid setup. You may need to adjust your scalar in the flash if the 100 octane fuel you are running is maxing out your trims like that.

Hi Steve
The weird settings you’re mentioning, which exactly?
At the WMI or?

Before I did these logs, the only thing I did before that was updating JB4 to newest Firmware G5_ISO_32_15 Beta and then putting in the user adjustment settings for hybrid turbos from this link where Terry writes its a good starting point..
JB4 N54 Hybrid Turbo Setup Directions - N54Tech.com - International Turbo Racing Discussion

I haven’t myself done any of the settings in WMI, it came with the firmware update, so also makes me a little confused.

Only thing under user adjustment settings I tried to change compared to Terry’s hybrid settings was the Meth Trigger mode to 3 instead of 0.

May want to try reloading the latest firmware....there are a bunch of random numbers and settings on the WMI settings. Or if not using meth or an FF sensor, you can zero everything out on that page and deselect 2 and 4 under ethanol setup.

Hi guys

Today I tried updating to newest interface and firmware in the 335i, could see that Terry had already uploaded the new hybrid turbo firmware, so here's the results.

Remember I'm not using any kind of WMI on the car, so that shouldn't be activated anywhere in the settings, only pump gas (100 RON gas in Denmark) which is around 95 PON gas in USA.

I've put these settings in and the hybrid user settings, please take a look at my logs for changes.
Firmware: G5_ISO_32_16_T3
Menu 04 = 2
Menu 12 = 2800
Bit6 Enabled
3.5 bar Tmap = 1
Fuel Open Loop set to 90 instead of the default 40

From map1 I was kicked into map4 two out of 3 times.
Only after first run I had this error code:
30FC exhaust fume turbo charger, density

From map6 I wasn't kicked into map 4.

After a couple of hours driving I could see that under user adjustments the
FF/wastegate adaption had went from the 100 to 81.

And under WMI settings (which i'm not supposed to use)
Virtual Sensor Offset went from 0 to 132.

In the JB4 program under the Logging page when connected to the car I also find it weird that where you can add Meth or E85 to the log I would expect it to show 0 in those fields, since it's not in use, but Meth shows up tp 255 and E85 I think was up to 58 or something?

Input/advice what to adjust will be much appreciated.

You're running lean at tip in in the log I reviewed (map 6 run 3) as trims are maxed out and HPFP is about to crash. You'll need to sort out your fueling or run less boost.

When you write fueling Steve, what exactly are you thinking then?
New HPFP with better flow only or more than that?
Any good suggestions for new parts?

Which BMS BEF are you running?

You're trims are maxing out on 50. When the trims sit at 50, you'll run lean and trip to map 4 on a lean safety. I had the same problem, and the BMS BEF solved it for me.

You'll need to help out your HPFP. DPMI (Direct port meth injection) would be a nice option if you don't have E85 in your area. This would help out your HPFP, increase your octane, lower your trims, and provide charge cooling.

@Steve, I don't have plans for using any kind of WMI and we don't have the E85 fuel, so if you don't believe my thoughts here underneath maybe could help me out, then I will need to lower boost.

To begin with, back in 2015 I had a tuning company with Dynorun to flash the car and they had a link from JON with the BEF which they should use, so I believed I had a JB4 BEF put in the car at that time.

Automotion then asked now about which BEF is installed, Terry also did and then I started wondering which one is actually installed.
So I ordered the MHD OBDII WIFI Adaptor and according to that, then the last flashed file is: UNKNOWN (see MHD DME pic)

Shouldn't the flash say JB4 something for being from BMS and not just Unknown?

So would it maybe do some magic to the car if I flash it with the newest 020719 JB4 PUMP.bin file and i guess that the one not called USA is the one we shall use in European cars?

Or wouldn't you believe that it would change anything at all?

And can I flash it through the MHD wifi adaptor or is the special OBDII cable and OTG adaptor needed?

Then another confusing subject which I can read others also have, which version to flash, I8AOS or IJEOS?
Car is from 17/1 2007, but I don't know if the tuning company can upgrade a DME with and update and maybe did that..
Cause I can see in my JB4 user adjustment screen that it's been the IJEOS I've been running under since I was at their place in 2015, but that doesn't show any IGN 3 and IGN 4 in my logs.
-The sticker on the DME itself says MSD80 (I8AOS)
-MHD wifi adaptor also says HW: I8AOS (see MHD DME pic)
-Realoem.com with VIN PR43397 only comes up with MSD81

or do the factory software: 7573870
and the current software: 7628410 shown in MHD flasher tell anything

Aln, following with interest as I'm a DK resident as well. In a less radical 335, though: 335is DCT Quaife, fbo MHD 2+. 419whp and lots of codes

Did you check out the "local" forum ?: Danskere... How many Danes? - Page 219

Impatiently waiting for Danish E85, but meth injection sounds nice!

greetings from Cph

Mike

Thanx for info The Beast..
And I've read somewhere that if it isn't the I8AOS version it needs, then the MHD won't even accept it and won't try to update with that version.
But if that's totally true I'm not a 100% sure about?
Since I'm in Europe I'll use the none USA version of the PUMP BEF.
And definitely take a back up with Mhd of the flash there's on It now.
But I guess that since I haven't had MHD connected to it before, then I'll need to make a full write up?

@Mike, yes I've seen that forum, also a nice one

Hi Guys
Now I finally had some grown up time and got a BEF update done trough the MHD wifi adapter.
I've updated it with the JB4 PUMP FLASH for I8AOS.

Please have look into my attached logs for changes for optimizing, I've also attached my user settings.

I wasn't trown into map 4 at any point during my drive.

Map 1 looks normal, on map 6 trims maxed out for a bit down low but otherwise looks normal.

What are your thoughts about trims in map 6 Steve, is it too rough for my HPFP and would it suddently crash?

Can any adjustments somewhere make a nice move regarding the trims or is the only solution E85 (which I don't have in mind) or lowering boost for map6 in user settings?

Can you suggest anything else for improved performance?

It feels like it revs slower than it did before I updated with the
pump flash I8A0S here recently and I can also barely hear the Tial blow off now?

Really appreciate all the help I'm getting in here

Maxed out trims can cause you to run lean so you'll need to watch that.

The log looks pretty good, adjusting the fuel scalar down low in the flash would resolve your issues with trims maxing out. HPFP looks fine thus far.

You're running map 6 and other than during turbo spool, boost is hitting your targets so I don't see an issue there.

uuuhhh Steve, that sounds like something I haven't got'n any clue about how to do

Is that in the BIN file "JB4 pump flash" for the I8A0S something needs to be adjusted and then I should flash the car afterwards with the new adjusted BEF flash?

Is that only changes for MAP6 and then I would need to flash the car every time I want to drive in MAP6?

Or would the custom made flash work exellent for all maps?

Could you maybe be helpfull with making that custom flash and then I can download the file afterwards?

The flash map is active on all JB4 maps. I don't do custom flashes, you'd need to contact a tuner that does for that.

Hi
I would really appreciate if someone please could have a look at my files here and let me know if you've got'n some kind of idea about whats going on with my 335i?

Suddently it was back firing like hell and smellt burned and sounded like a tractor and wouldn't really take much gas.

Error Code in JB4 program:
30BA DME digital motor electronics, internal failure.

Error Code with MHD:
30BA DME: injectors 1,2,3 or DME internal fault.

*I've checked the Mosfets and only contact in the middle on all 6 as it should be.
*I've tried to changed spark plugs (old ones looks totally fried)

Can't really drive and sound like a tractor and everything is shaking.

Don't know if Coils could be the reason.

HELP, please

Sounds like MOSFET to me. We have replacements on our website if you want to DIY repair it.
