Question JB4 Settings N55 PWG - 03-30-2019, 08:29 PM

I am trying to figure out what are the correct User Adjustment Settings. Mainly just for the Duty Bias and Default Wastegate Position.

When I received my JB4, Duty Bias was set to all zeros and the DWP was set to 80. It was pointed out to me that these are the correct default settings.

Everything was the same except for Duty Bias and DWP. When looking at the thread below, I noticed there was a reference to setting the Duty Bias to all 50, but that was under the EWG firmware.

My car has the PWG. So should I be using 0 or 50 for Duty Bias and 60 or 80 for DWP? I plan on primarily using map 2.

Duty bias at 50 or 0 across the board will have the same results. FF will need to learn up or down but having either value is fine. I believe the suggested DWP is 60. I had to set mine to 80 on my 335i to avoid a slight surging issue.
