Title: MED 9.1 actual boost pressure cap BGB Post by: BetePaille 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 !

Time to start using VehiCAL and to log actual RAM variables rather than ass-umptions.

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?
Title: Re: MED 9.1 actual boost pressure cap BGB Post by: fknbrkn on May 12, 2026, 06:43:20 AM 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 |
