Upshift Boost Spike Prevention

When the vehicle shifts into a higher gear under full throttle, the sudden reduction in engine RPM can cause a momentary but substantial increase in boost pressure. This can be a particular problem on vehicles with larger turbos running at high boost pressures. The spike prevention feature detects when this is likely to occur and opens the wastegate for a fraction of a second to prevent the spike from forming and ensure a steady and consistent level of boost.


Without Spike Prevention - Spike to 1.43bar With Spike Prevention - Spike reduced to 1.26bar
