protuningfreaks Coolant Pressure Sensor Kit – Essential Fail-Safe for High Power BMW B58 & S58 Engines running REV2 Controller and bootmod3 CustomROM V2
Protect your high-performance B58 and S58 engine with the protuningfreaks Coolant Pressure Sensor Kit—the ultimate plug-and-play solution for monitoring coolant pressure and preventing catastrophic failures caused by head lifting or head gasket issues.
⚠️ Important: This kit requires REV2 and CustomROM V2 for full functionality.
Key Features:
✅ Fail-Safe Protection: When connected to the REV2 Controller, the sensor transmits real-time coolant pressure sensor voltage data over FlexRay to the DME. Tuners can set a maximum pressure threshold in the DME map to trigger failsafes such as cutting any/all power adders (boost, nitrous), port injection, di injection—helping prevent severe engine damage.
✅ Seamless Integration: Available in two versions to ensure compatibility with your setup.
✅ Easy Installation: No cutting or modifications required—our kit connects directly to the factory coolant lines making installation quick and hassle-free.
Includes:
- 6061 Aluminum CNC Coolant Pressure Sensor fitting
- Viton o-ring
- Metal c-clip for factory mounting
Optional:
- 10 bar (150 psi) pressure sensor
- PNP sub-harness for the REV2 "CP" input connector
Upgrade your build with the protuningfreaks Coolant Pressure Sensor Kit and drive with confidence knowing your engine is protected.
