MED 9.1 actual boost pressure cap BGB
« on: May 03, 2026, 01:35:07 AM »
Hi,
Is there a way to log ACTUAL higher than 2550 with 3b map sensor ? VCDS reads pvdr_w which is limited to 2550. pvd_w goes to 5160 max. Even with 3b map (gradient / offset done accordingly), as soon as boost goes higher than 2550 mbar I get throttle cut and +25% STFT (load limiter permits it with 250 RL and KFLDBHN FFed).
K04 antisurge core + RS3 injectors (6 ms so no issue there). I don't see any major differences in Golf 6R damos which doesn't have this issue?
Thanks !

I think if you went and actually logged all your requests, you'd realize that your load limiter doesn't permit any kind of 250% as you think. Time to start using VehiCAL and to log actual RAM variables rather than ass-umptions.

I have no logs because I have a boost gauge (makes things easier)

You are right. But with all limiters FFed and KFLHDBN 2.7 all over the map, the car still wont see more than 2550 actual, even with 3 bar map sensor, and cuts even when not running lean on STFT. Are there some AXX/BGB with issues in the code?

you can log pvd_w instead of pvdkds_w with changing 'i14230 tabelle meskanale' (77 to 1774)
but plsol would be limited anyway
impossible to tell something specific about the reasons of throttle cut here
