Hello everybody. I am working on my car and I can't seem to have the capacity to manually push the WGDC at high revs. I have a good result with the car running 1.5 bar constant at high revs with boost dropping at 1.25 at redline. Now I'm trying to push a constant 1.8 bar between let's say 4500-6500 RPM and drop @ 1.25 at redline. I tried modifying KFLDIMX and KFDLRL in those ranges (setting DC to 70) but in the logs the DC is not constant at all, it is fluctuanting as can be seen in attached logs. Can enybody explain how I can go open loop above 2550 requested boost? Should I flatten KFPLGUB?

What lambda do you usually go for in those areas in order to keep EGTs reasonable? Is 0.77 too lean?
Regarding timing retard I can’t do any more. I already pulled about 4 degrees and I m on the best fuel I can get in my area.
Injection timing and lambda control went up when I changed the axis of KFMIOP to 220 max load and LDR to 220 as well. I will revert to an earlier version and try to fix what you mentioned.
I know injection timing should be under 8.x, but for power levels above 350 do I need to adjust FKKVS as well?

Thanks you for your answer. The car is a S3 8P BHZ with all the standard mods for a stage 2+ for powers ranging from 330-360. Meaning stock k04 stock s3 injectors intake and exhaust, upgraded vis hpfp, rs4 prv, big fmic. In theory from what I've read online the car should be able to handle fueling on stock injectors up to 360-370 hp on 98RON. Now I do not know what mistake I made that caused the lambda control to spike to 25%, but it seems that the lambda value never really exceeds 0.82. Rail pressure request is at limit as the rs4 prv opens at 136 bar. I will do a few more runs and recheck. If I can't figure out the overboost thingy, I will be trying as a last resort to switch CWMDAPP to 8 and run open loop via KFLDRAPP even though I am well aware of the negatives.
