I think you're on the right track with the purge valve. Try what is suggested in this video.

Hmmm, does the purge valve properly click when the car is idling and is plugged in?

Also, if the internal diameter of the original intake differs to the diameter of the cold air intake, you will...

You don't see valve float below about 6000 RPM on these engines. Not even with a bigger turbo.

No need to turn off primary O2 or closed loop, that's a dangerous game when you don't have a wideband.

What is the difference in the internal diameter in the pipe where the MAF sensor is located...

Overboost/underboost distabled, turbo overspeed limiting removed, wastegate DC increased to 99%, knock airmass set to 1 across the whole range, MAF diagnostics disabled and on top of it all, up to 6...

Different E78 ECU operating system number, that's why. Memory layout changes sometimes. Can you link the .hpt file here? I could try some offsets.

How does the car behave if you simply plug off the MAF sensor and keep driving (please log this)?

The P1101 code makes me think the MAF died, or somebody cleaned it in some aggressive cleaning...

On the second look, you have 3 check engine codes logged

P0171 - System Too Lean (Bank 1) (Pending, Permanent)
P1101 (Pending, Permanent)
P0420 - Catalyst System Efficiency Below Threshold (Bank...

Is that tune file the stock file for this car, or the current tune that you're running?
What kind of intake is on the car? If it's just running an intake, but the MAF sensor was not touched,...

Their post is next to worthless from a tuning perspective.

Ended up using Emu Black standalone ECU and doing it there instead for unrelated reasons, but here's the current cam angles i am using....

This smells like scavenge mode to me, speeds up the turbo spool. When the actual MAP is lower than desired MAP, the ECU switches fueling, intake and exhaust cam angles and timing.
Does the car drive...

What kind of fuel are you running? And what kind of hardware changes do you have on the engine?

It's very likely the original OS already supports this to some extent, it's just a matter of enabling a few flags in the calibration and use proper tools and definitions, which isn't easy.

Digging...

Not all computers work the same. If you have a key fob with a button press start, first button press will usually do nothing and turn the ECU off. Pressing it again starts the car. Normal key fob...

1. You don't have to buy credits to do a read, only to write to a specific computer. And even if you write some changes, the dealer update will just overwrite everything without bricking.

You cannot use Alpha-N in boosted situations, because part-throttle you may get full boost or you may get half boost at times. Alpha-N only takes the throttle blade angle and RPM into consideration,...

Try setting this whole table to 0, together with the A/C Disable TPS set to 0% and Re-Enable TPS set to 200%. Alternatively you could bypass the sensor with resistors, both 2 pin and 3 pin...

Did you wire the injectors correctly? They should have +12V on one pin, and the ECU grounds the other pin to fire them.

Sadly no updates for now, lost contact while flashing. I need to get the immobilizer removed on the new ECU before i can continue. VATS off in VCM Editor does not work (yes, i did write entire).

Play around with the green highlighted tables. These are my current settings.

I, currently, have the same problem. Bricked the original ECU because it lost power with the key-off position. I got a replacement from a 1.4 N/A.
These are Gen 2 E78 ECU-s.

It should look like this, i opened a ticket for that one last year, seems they didn't add it for all operating systems. I don't think it's for gearbox protection but for economy.

Updating this thread because i have found a solution to the traction control "issue".
Operating system number 12683718 has only these switches defined by default in VCM Editor.
