Any chance to enable seeing coolant temps?

I still haven't had a chance to add that option to this firmware, but it's on my list.

Here are the results -> 5th gear, 1500rpms, DB is all the way 50, FOL 50, PID GAIN 25, FuD 174 (because of FuD settings the system is not logging gear and all cylinders, when I answer the questions I have value 174 which is again not logging the gear and the timing, but if the value is 99 everything is fine).

The real (JB4) boost seems to be fine until 4700rpms and then it starts dropping.

The next steps for me are:
1. To figure out the right FuD value; (I would appreciate some help, as when I press Bits and answer the questions I am not getting the desired results. From what I read bit6 is the one responsible for the timing, but there the question is different).
2. Adjust DB starting from 3000rpms to try to have the FF and WGDC as closer as possible; (Am I wrong or this sounds a feasible start?)
3. FOL 50 seems to be a good much in high revs, but in but 3000-5000 the car seems to be running on the lean side. Adjust to 60 may be?
4. I am thinking of raising the FUA above 30 so I would get less throttle movement. Would this be a good idea? Currently I see exactly .8psi difference all the way.
-> Looking at my log from 2000-3500 rpms there is higher than 20% throttle movement which I cannot explain. Boost (DME_BT/ECU_PSI) is .8psi off, the JB4 Boost/Target is near even a bit on the lower side, but still the throttle is closed. At 2000 rpms there is .9psi overboost (above JB4) which can explain the throttle being closed about 40%, but afterwards everything seems fine while the throttle remains half closed.
5. ... @Terry, anything else?

P.S. I would assume, now when I have the WGDC demand, it would be fine to log in 3-4th gears as in 5th I am reaching quite a high speed which is a bit illegal
Load on this firmware is manifold boost pressure. If it matches pre-throttle pressure, the throttle movement should be ignored.

FUD bits definitions are in the first post if relevant to this firmware.

In terms of WGDC you see it ramping up around 3500rpm. Also noticed you DID NOT load the default values. You just set everything to 50. Anwyay something like this might be worth trying next:

1500: 50
2000: 50
2500: 50
3000: 50
3500: 54
4000: 58
4500: 62
5000: 66
5500: 72
6000: 76
6500: 80
7000: 84

I thought 50 is the default? The FF adaptations weren’t turned off in the above log. I did few logs today but without any satisfing results. I managed to map the FF/WGDC (with WG adaptations turned off from the bits) curves but I was getting underboost in high rpms. Now the FF Adaptation is around 105 and DB around 86 at 5,5k rpms.

Should the adjustment procedure include adaptations turned off or not?

Enclosed is the log and afterwards slightly adjusted settings which I never got the chance to test as it started raining.

Second log is after the FF adaptations were ON and the curve starts looking at staircase: I would assume I should drive with the FF adaptation turned on?

P.S. After the below run I turned ON the FF adaptation and it went to 105.

Default settings are in the first post. Your duty bias doesn't seem to be entered right either. FUA and FUD should both be 0. PID gain should be 25.

If you require CANbus on full time then you can enable that FUD option.

I used the "all 50" from the other thread.

Anyhow I will do some runs with the suggested FFs (the ones from your post) and FUD/FUA = 0.

What would mean if I require CANbus on full time? The CAN wires are directly connected to the OBD connector with the JB4 connector and I am only attaching the laptop to the Data cable when I am logging, thus I am not sure what is the CANbus on full time (I thought it is usually always on?) and if I require it.

If FUD = 0 this means that the FF WG Adaptation would be active, thus this value would be incremented with every run, correct?

The thing I don't fully understand is the FF Adaptation, which when active is always moving up (never saw it going down), thus if I do the default settings for the DB (listed in the first post) the FF Adaptation would raise even during the first WOT which would again mess the WGDC/FF curves. I read that the FF Adapt is considered to be the global variable, thus it will increase the FF thru the whole range by its value (based on the formula) and then additionally add the DB rpms gain, or this is not correct.

In my latest two logs I have in the *_OK log (with disabled FF WG Adaptation) a good matching of the FF and WGDC curves (with small remark on 4k-5k range) and in the next log, where the FF WG Adaptation is ON the FF curve starts to get away from the WGDC (there the FF is 90) and at the end the FF WG Adaptation is 105m thus if I log the curves would be again away?

The only settings that apply to F PWG ISO are those in this thread.

CANbus on full time was a setting for those cars that throw codes at low throttle when not logging, when JB4 CANbus is sleeping.

FF adapts the curve up and down as a function of weather and other minor changes over time. Sometimes it's helpful to disable it when dialing in dutybias but normally not required.

In the last logs you failed to enter the correct duty bias values, so they were useless to evaluate.

Your car is an 535i F10 - right? In that case use FUD=2 to enable F10 compatability.

It's FUD bit #1 to on for F10 BC button control.

I'll specify even further

bit0 - No
bit1 - Yes
bit2 - No
bit3 - No
bit4 - No
bit5 - No
bit6 - No
bit7 - No

- OR -

FUD=2

I don't use dash control. I only enabled CANbus full time (bit5 => YES => Value 32).

The DB settings are now adjusted, I would do few runs later when the road is drier and report back.

EDIT:
Enclosed are new logs. 5th gear until 5k rpms (ran out of road ).

Settings as suggested from Terry for DB. FF Adaptations untouched; FUD = 32 (CANbus full type (Bit5 => YES)).

You also have some CANbus speed issues. Enable slow speed CANbus, bit#7. This is not uncommon on F10 models.

Okay, I will do that. Otherwise Look okay? Boost timing? Should I tweak anything else or?

Fix CANbus speed next and relog.

I am about to go do that.

I drove the car without having my laptop with me and I got Drive malfunction (error said Boost lower than expected) and the car was hesitating between 2,5k - 4,5k as the boost was not coming.

EDIT:

Here is a log on 5th gear (171120_2113) with Slow CAN (Bit7 = YES). Bit5+Bit7 = 160.
The other two logs are 1 full 4th and 1 3rd-5th.

P.S. Now the Gear and Ign are gone
