I noticed that in the definition files the launch control files are 512k and the are with ews delete. Is there a 512k without ews delete with launch control and the rest of the goodies?
You are working with the older file set. Got to https://www.ms4x.net/index.php?title=Siemens_MS43 and start over with the files from there. Pick the virgin 512k file for your engine and then patch it with TunerPro for whatever you need.

I was not ready changing the settings drastically, but now Iím more confident thanks to you!

I Tested it today, in the morning was first run over German autobahn.(at around 20 degrees celsius).
It felt really nice, pretty torqy in lower rpm and stable up to around 4k.
Couldn't rev to the end due to traffic, but tested that on the parking lot of the company i work for. Well i left it rolling in 2nd at around 1.5k then took what he gave, it was nice felt also not less or more than my previous mess, just at the end of the lot i was just hitting 5k, it suddenly started to pull even stronger. I am not sure if i was above 5k because i had to look where i was driving and keep the car under control while i threw an anchor to stop and avoid hitting anything.(Its a dead end). Then on my way back at around 30 degrees it was the same nice powerful and torqy feeling, despite the autobahn had some sections where less traffic was i tried to reproduce the sudden kick from the morning, but id did not come.
Next thing i noticed, i could not feel the mentioned torque loss above 5.4k rpm. Maybe because my DISA is open instead of closed at the end.

Great work

Can someone clarify the vanos settings? Ive been reading that retarding means exhaust going -80 -> -105 and intake going 120 -> 80, also read the reverse that redarding means exhaust -105 -> -80 and intake 80 -> 120. What is correct? its starting to annoy me, would like to know so I might can take some inspiration when going freeflow exhaust now.

Masterchief83 i did some logs during afternoon without ac and it was killing me
Anyway I put on some more (or less due to the b30 Cam) overlap at the end of rev range and the power is good. I donít quite understand how it is possible to run this amount of overlap atm.

lollipop, advancing the intake means you decrease the numeric value (for example from 120 to 110), advancing the exhaust is same ( for example -80 to -105). They both decrease. When you increase values you retard from 110 to 120 and -105 to -80, as examples

you can keep your fuel and do changes to higher load only + full load maps.
i think BMW offer a pretty big safe margin setting limiters to ~6.4k ,limit yours to 6k to be extra safe and benefit from power that peak @5.9k.
if you have compression down low,overlap on middle and retard on top (free flow ex) you can continue with improvements.
I started with your ideas and they don't work. That is why I am where I am. With a stock exhaust, max overlap is needed to get any scavenging as there is no tuned flow only reversion.

Guys dont forget every m54 is different , so people's settings will be always different. You take 2 identical set up and i can say for sure with same tune on them 1 will run better than other. Thats what I always encounter tuning my friends cars. 3 of them have identical set up and all 3 tunes are different. have no clue why but it is what it is . Also everyones butt dyno measures differently(some have more seat grip than others)

Regarding what Racing teams do(they optimise so far that the flow of air and fuel connects to a kind of stable and unslowed stream through the engine. i'd say, that engine entered Race mode

I'm flashed how that engine runs, especially the long rpm-bandwith where it delivers torque.

I added a degree more ignition and 0.100ms of fuel this morning, it felt nearly same(hey its just a degree), but i think the pickup and torque built up when transitioning from rolling to pulling is better, if i do that around 4k and step on it fast, it acts kind of brutal, there is no delay between pedal work and torque delivery, i think it comes even harder or stronger, but regarding that this is felt by my personal Butt-Sensor it might not be stronger, just feels as it would be because it comes hard and at the time the pedal is pushed.

Maybe there's more, i'm not sure if i cleared adaptions after unplugging lambda sensors behind the cats (it's set up on 1, so if they're plugged they'll be used, if not it doesn't learn), i read that this should be done with Inpa, but how about the less computerized way? disconnect battery or reset via ("secret")menu of the dash.
Does anyone know?

Understood, is this the virginized file?

Siemens_MS43_MS430069_E46_M54B30_EU2_LHD.bin

on the ms42 the cvrginized files are noted, on the ms43 nowhere says virginized. Also is the software version 0069 a poblem for flashing the 64K file with tuner pro? I recall reading that only same version 512 and 64K files can be flashed or otherwise I can brick the DME

Im still trying to blow up my friends b25 , so far 6 degrees advance on timing and a little tune with vanos , thats exactly what we experienced, it feels a lot more responsive , definitely got more torque. Also I adjusted DISA on b25 just to see , on part load and full load , on both maps I turned off disa and step earlier , and there was a major improvement for sure. ( specs: m54b25, headers ,sap delete ,stock intake , stock motor thats smoking a lot ) Once b30 gets delivered we gonna send it to 7500rpm or more for final rip, knock maps untouched , on logger it shows desired ignition with no knock , so im sorta confused why it dont want to blow up.

No no other way... I have a data display from Alexander (atm not in) which can reset adaptions. Lovely!

And oh Boy... lots of power hidden in Blues tune! Great base for further Ąimprovementsď (for me)

Do you run the standard intake cam or the b30?

One thing I have noticed is that the MS45 reports the real vanos values when logging, not the "learned" values. I am seeing this showing up at idle as 113.5 instead of 112.125 as I have programmed.

I have noticed that as little as 1.5 on the exhaust makes a real difference up top.

Hi Guys,

I have a strange Problem.
My Adaption is gone. Not working anymore.
Something prevents the dme to go to closed loop Adaption.

Setup:
2 PLX Wideband Controller pre cat
1v Narrowband Output directly connected to ms43 pinout.
I can see readings from Lambda.
Do i have to connect some from the ms43 Pins? For example Set pinXY to ground to get closed loop again.

First I had 1 Wideband controller and connected Narrowband Output directly to ms43. I Just cuttet cable from pin14 from x60002 connector and welded narrowband output from controller to it.

Now I added also a wideband controller for second Lambdasensor. Connected the same way.

Maybe someone can help me.

See Picture for INPA Readings of failure patrol Adaption

I bet there are fault codes with the sensors. The DME has turned them off because of faults like heater circuit.

I swear, no errorcodes... I suppressed the DTC's for cat heating . Is it enough? Or has the lamda heater be disabled somewhere?

Daniel_f will know if suppressing DTC's only stops them from showing and not generating the fault internally to be used by fault routines.

Hey did you drive with AC on,too?
I Had it that way these hot days and, well it was like "are you kidding me" it felt like chewing gum drive mode, less power and less reaction speed.
Turned AC off and it went as usual.
Someone an idea why that happens?
Maybe ignition adaption for AC ? (Anyone know which table(s) that is(are)?)
