THIS is why i wanted you to post it here. 140g/s for a 180hp tune is low. A healthy 150hp must flow about 130g/s at redline, a healthy 180hp should flow 150g/s at redline. You might have a vacuum or boost leak, maybe a defective component somwhere... this is why you are having underboost issues and not reaching requested loads.

My car has reached 130g/s with 150hp tune, 152g/s with 180hp tune, and now I am flowing 164g/s at 5700rpm and 169g/s at 6300rpm. Which I believe to be the absolute reliable limit to stock k03 turbo.
Sorry there was some misunderstanding, I was just wondering how any real figures above 180hp would be possible with a stock k03, but then Leonhard pointed out that my compressor map was wrong. I believe the car has the K03 with 2072 compressor which looks much better than the 1870. I did one more log and it seems it works acceptably well. The slight underboost happens between 2.5 and 3.5 krpm for 3rd gear pull. For 4th gear its better, and for 5th gear it is almost perfect. This looks like a job for PID tuning, but I don't even know any other maps except ZSOLLDRN. I think I will just leave it as is...

Edit: About ZSOLLDRN... It says "Boost Control Filter Time Constant for Low Pass". I know what is a time constant of a low pass filter, but low pass where? The feedback loop can contain more lowpass filters... And the values in it (below 100ms) are still much shorter than the duration of the overboost (like a few seconds).

I have a vag409.1 I can use to test a few basic things, however I have no any ecu compatible

Hi folks.

I would like to share this fork repo https://github.com/ljscodex/NefMotoOpenSource

I just updated the master branch to run on NET8, if you wanna run the project and let me know if is working will be amazing, I have no RS232 cable to test it right now

Thanks! very much appreciated. opened an MR but need testers.

Would be good if we can get automatic builds with github actions.

Actually, also wondering what other issues this might fix https://github.com/NefMoto/NefMotoOpenSource/issues

I wonder how anyone could get any more with stock turbo. The 180hp variant runs at about 140g/s MAF at full power. See attachment...  Huh Huh Huh

To estimate power it is said through the internet to use maf reading/0.8 but I consider this calculation too optimistic as 130g/s would translate to 162hp. I use mafreading*1,2 which translates 130g/s to 156hp (more accurate on my perspective). Same for 180hp, do the maths. 169g/s*1,2 is 203hp, which I belive to be accurate when running against similar power/weight cars.

Smoke test your car and make a thorough check. Untill you don't get those values with stock tunes, do not tune any further.

Best regards.

I tested(not made log on the street to see if ldrxn/kfzw and lamfa changed) on aum today , map switch works and check engine light.
I tried activate launch : Engine Running , push brake 2 times, push clutch 3 times ,push acc_ped at some rpm and kept constant and push brake. NO check engine light , and no launch activated. i tried with and without AC.
stuydub, some advices?

Other issue/question, the launch will be deactivated after ignition off, or remainig active? If remaining active how will deactivate it?
Thanks

Confirm what stuydub told. The chinese clone of mpps v18 and v21 is the same.
I had 3 of them and all are blocked after some read/write. They are undetectable in windows as usb port / driver.
stuydub can we make something to unblock them or rewrite their firmware?

Leon, thanks for the reply. There were two variants of the 1.8t 150hp engine, the earlier like AGU with large port head and smaller k03 turbo (and mostly M3.8 ECU), and later like AUM with small port head and slightly larger "k03s" (though Im not sure if this is the official designation). The compressor map you posted is for the smaller k03? I was not able to find the exact type number and assumed its the 1870.

Why is your TVUB not matching the finjector specs you linked to  Huh

plug in stock maf and tune fueling first...
