BMW B46 B48 B58 Motiv ReFlex 0-10 Bar Pressure Sensor is designed for accurate measurement of fluid and air pressure in high-performance applications. Ideal for monitoring a variety of pressures including fuel, boost, coolant, and oil, this sensor provides crucial data for optimizing vehicle performance.
Featuring a 2-Pin DTM connector, this sensor offers a direct plug-and-play connection to the ReFlex+ harness, ensuring a seamless integration with flash platforms via CANbus. Each ReFlex+ unit can support up to two of these sensors, allowing for comprehensive monitoring.
For optimal installation, consider using the 3/8 Female to 3/8 Male SAE Quick Disconnect Adapter with a 1/8" NPT port on an ethanol sensor or the 5/16 Female to 5/16 Male SAE Quick Disconnect Adapter with a 1/8" NPT port on a factory fuel line. Please note that the ethanol sensor is not included.

Adding between 60-75 WHP/WTQ on BMW S58 powered applications, the Dinan PCU is our newest in-line tuner that not only gives more power but also many additional features accessible via our free BT phone app. Changing power levels as well as monitoring the health of your vehicle via logging, code reading, and gauges (to name a few) has never been easier!
More Power: Max gains between +61-67 HP and +57-73 lb-ft TRQ (Wheel); +70-76 HP and +61-77 lb-ft TRQ (Crank), depending on application
Bluetooth connectivity and control via free iOS or Android PCU apps
Multiple power levels, plus stock, to choose from
Designed for peak performance utilizing pump gas fueling; 91octane tuning (levels 1-3) and 93 octane tuning (Levels4-5)
Improves power and torque across the entire RPM range
Customizable in-app gauges
Real-time logging up to 20 (16 max at one time) parameters courtesy of CAN/OBDII integration and the supplied PCU app
Logs can be viewed directly in the PCU app or exported/emailed as a CSV file for more detailed scrutiny
Boost by gear user customization to reduce unwanted wheel spin in lower gears
Read and clear fault codes as well as check emissions readiness
Retains all factory safeguards and works flawlessly with onboard emissions controls
Unaffected by factory updates
Plug-and-play installation
Unplug and go back to stock at any time or transfer the unit (Not VIN locked)
Designed, developed, and manufactured entirely in the USA
Developed wholly from the ground up, the Dinan Power Control Unit (PCU) is an evolutionary step in Dinan in-line tuning models based off over a decade of lessons learned in the category. At its core the PCU is like its precursors and installs in between select sensors and the ECU, adjusting these signals in order to achieve increased performance the stock programming is unable to approach. However, what sets the PCU apart is its integration into more than just the fundamental boost sensors but also additional connections--inclusive of OBDII. The result is a more capable system that can do so much more than just increase power. Live monitoring of vehicle health via logging, customizable gauges, and code reading/clearing, among others, are now possible ensuring a seamless tuning experience even a novice can be comfortable with.
The Dinan PCU is controlled by a free Bluetooth app, available for both iOS and Android, and is home to all the potent features the device offers. Equipped with 5 different pre-set performance levels, in addition to stock, you can choose to select your desired output and enjoy more power for a true install-and-forget experience, or you can opt to engage in the more advanced features at your fingertips. Boost by gear customization, as an example, allows you to limit power delivery as you see fit in lower gears ensuring optimum traction and a perfect launch. Where the PCU shines however is in data acquisition and monitoring that gives insight into the vehicle's overall health and makes certain your tuned vehicle is always running at peak potential.
Safety and reliability have been cornerstones of the Dinan brand for generations and not only does the Dinan PCU not hinder any factory safeguards or emissions controls but incorporates its own safeties as well. Going one step beyond our own internal protections, the PCU also grants the end user the ability to monitor up to 20 different engine parameters in real-time via customizable in-app gauges for verification of worry-free operation. Those same parameters can also be logged/viewed in app (or exported to CSV) for further scrutiny if desired.
All told, the Dinan PCU delivers more power and more features with improved reliability and drivability than ever offered before. Performance without sacrifice is alive and well!
SKU variations / Warranty: The Dinan S58 PCU is available with a standard 2-YR product-only warranty (Dinan S58 PCU–D440-0200) or a factory matching 4-YR/50k mile warranty (Dinan+ S58 PCU–D440-0200-W) that covers both consequential damages as well as labor reimbursement. Functionally, the units are identical but carry different warranty terms. In the case of the factory matching warranty Dinan+ PCU, the warranty ONLY applies to the first VIN the unit is installed on. Successive VIN’s will not be granted warranty coverage from Dinan.
