But when wgdc set to a constant pid is not working...

Then don't set wgdc to a constant.

How to do the WG linearization without that?

Ok now I follow. You mean you don't want to break your car while running test pulls.

Just be careful. If you didn't remove any DTCs or controls you should be fine, as long as your fueling holds up.

Limit your wg/rpm range to safe areas when you're doing pulls.

Hi guys, I'm in the process of PID tuning on my 1.8T. I was a lot surprised because I have 1.8T with k04-015 which should be equivalent to k03-073 but my turbo is so strong (considering small K03-04 turbos) that I was really  scared to finish the runs  Grin
With 50%DC I'm boosting 20PSI in 4000rpm and 14PSI in 6000rpm. I finished it on 50 percent and decided not to continue because I dont want to throw a rod.   Elrey in the first post mentioned that he is running also k04 on his passat and on 50%DC he was still far from 14PSI.

I need to analyse logs and make new KFLDRL from it so I will see if I'll be succesful or not. I couldn't imagine put some strong Garret in it or some F21L and make linearisation runs than.  Shocked

It's much easier to get rid of linear boost on a big turbo than a smaller nervous shit

Use a time in x axis or a check wot filter in options

It's already solved. WG was okay, turbo was completely new but it is pretty strong. Through this manual I made new KFLDRL  (KFLDIMX linear) and now boost is exactly where it should be. Amazing thread.

The completed duty<->boost table above give me this:


Notice how non-linear the boost response to duty.

Then I carry down the 0% and 80% data columns and calculate the linear boost per duty steps. This is how.
For each RPM node find the delta boost between 0% duty and 80% (or highest duty you log).
Then using the 0% and 80% columns, map the linear boost for each step between them.
So, for 0 to 80 by increments of 10 there are 8 steps. I take the delta found for each RPM and multiple it by the increments of 8 steps + the lowest boost (0%).



Once I have this linear table I get this:


what software is this? that ui looks so much nicer than tunerpro haha

It's excel sheet, just for calculation, but author added nice charts. File is posted in this topic.
