Cold air will not boost

[Reiko]

Sry my english is bad.

I have a problem when the temperature outside is below 0 degrees, the pressure does not rise above 0.3 bar. What could be the matter?

The throttle is never opened fully.

If the AF is accurate then 13.5:1 under boost is very lean.

What is your wastegate setup?

[Reiko]

Activation pressure 1,68 bar.
When the weather was warm, it was fine but now it's cold, the mixture goes lean. The calibration of the first post.
Thanks Reiko

Had a faulty ignition coil!

Thanks for the update. I guess that would give a very learn reading in the wideband.

yea thanks for the update, also i never saw the car go WOT or even above 80% throttle, also things I noticed that should probably be corrected is the overall fuel trim should be brought back down to 0% and then move the fuel tables down -13% then re adjust, also your fuel table lines are so jagged like mountains where they should be smooth like rolling hills, by smoothing them out you'll get a much smoother ride on your throttle.
