Hi all
I have en R32 GTR that have a HKS EVC III (boost ctrl)
The turbos are running at 0.95bar and its one thing that have bugging me all summer! When boost pressure reaches 0.95 the HKS EVC warn me for overboosting? When it does that it feels like all the torque disappears and the boost pressure goes down to 0.90bar? All of this happens up to 5krpm
If I switch of the HKS EVC and let it run on default boost ~0.65 the car pulls nice all through the rpms. Sound to me like a setup thing? I don’t have the knowledge of boost ctrl so please help
Here is the HKS EVC that I have. Warning for overboosting is the button/light on the top right corner
