Please ensure your correct model is selected

BMW fuel system electronics are crucial for the precise operation of your vehicleaEURtms fuel delivery system, optimizing fuel efficiency, and ensuring engine performance. These sophisticated components control essential functions such as fuel injection, fuel pump operation, and sensor data to manage fuel flow, maintain the correct air-fuel mixture, and improve emission control. BMW vehicles may also be equipped with flex fuel systems that adjust the air-fuel ratio depending on the type of fuel being used, allowing for better adaptability to E85 or other ethanol blends. Additionally, fuel pump control modules play a key role in regulating fuel pressure and ensuring the pump operates at optimal levels. Common issues with fuel system electronics include malfunctioning sensors, failing fuel injectors, and damaged fuel pumps or fuel pump control modules, leading to poor fuel economy, engine misfires, or stalling. Solutions to these problems include replacing faulty sensors, upgrading to high-quality fuel injectors, and ensuring the fuel pump control module is functioning correctly. By investing in premium components and performing regular maintenance, these issues can be minimized, extending the lifespan of the fuel system while ensuring peak performance.

Arc Terminator now offers upgraded EKMP3 Fuel Pump Control Modules featuring a 22 Amp INCREASE in maximum current capacity over an OEM EKPM3. This allows for more current to be supplied to your low-pressure fuel pump (LPFP) without risking thermal overload, which often leads to your car shutting down. This means that you won't have to worry about being stranded on the side of the road while waiting for your EKP module to cool down, especially when you've installed a large low-pressure fuel pump such as a Walbro 525lph. How does the integrated automatic cooling work? The integrated automatic cooling works by us installing a thermal activation switch directly onto the new half bridge IC. When the half bridge IC reaches 50°C, the 40mm fan will turn on and keep running until the IC is below 50°C or until the EKMP3 stops receiving power. I have an EKPM2, can I upgrade to this? Yes. You can upgrade to this. We recommend using the HW05 and below module. You will need to code it in order for it to function properly. Can I run more than 1 low-pressure fuel pump off of this module? No. We do not recommend that you use more than one low-pressure fuel pump with any EKP module due to the factory wiring supplying power to the EKP Module is only 12 gauge, which is not rated for the type of power demands that two low-pressure fuel pumps would require.

BMW B46 B48 B58 Ethanol Content Sensor is a genuine Continental (VDO) Flex Fuel E85 sensor designed to accurately measure the ethanol-to-gasoline ratio in your vehicle's fuel system.

  • Accurate Measurement: Measures the ethanol content in fuel, providing precise data for optimal engine performance and fuel management.
  • Flexible Compatibility: Works with a blend of ethanol and gasoline, suitable for vehicles with appropriate fuel lines, injectors, and ECU calibration.
  • Quick-Connect Installation: Features quick-connect style fuel connections for easy installation in the main fuel feed line.
  • Integrated Fuel Analysis: All fuel passes through the sensor before reaching the fuel rail, allowing for accurate ethanol percentage readings sent to the vehicle's DME or ECU.
  • Standard Fittings: Both inlet and outlet connections are 3/8" SAE sized fittings for straightforward integration with existing fuel systems.

This ethanol content sensor is essential for vehicles running flex fuel, ensuring that the engine receives the correct ethanol ratio for peak performance and efficiency.

If you are running E85 or ethanol mixes in your BMW, you need this kit! This is a complete plug and play kit to install a Bluetooth ethanol sensor in your E-Chassis BMW. This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgraded -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer to monitor your ethanol content. Includes both Bluetooth App & 5v analog output for JB4 or flash tuning. For your fuel line upgrade, choose the option that supports your current configuration. HPFP to the fuel tank: (Stock) This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor. Port Injection to the fuel tank: If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel. Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup. Non-Fuel-It! port injection to fuel tank: Choose this option if you are running a port injection kit that we did not manufacture or sell. This kit includes a longer 18" feedline from the Y to the port injection rail. You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail. All of these kits utilize the BMS custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed. *For the BMW N54 E-series JB4 platform connect the white wire to position #15 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *For the BMW N55 E-series JB4 platform connect the white wire to position #16 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
