BMW Electrical Sensors, Switches, & Relays for BMW Z Series G29 (2019+)

Clear BMW chassis

Please ensure your correct model is selected

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

If you find that your SMG-equipped E46 M3 is not starting, this is one of the first places to check as it controls power to the hydraulic unit (the car will not start without hydraulics). Buy one to fix the issue and buy a second so you're not stranded in the future!

The MOTIV ReFlex+ is an Advanced I/O Integration module allowing a level of precise control of auxiliary components. In addition, the ReFlex can incorporate external data into the factory DME/ECU in parallel through optional CANbus integration. Utilizing the CANbus option, multiple digital and analog signals can be used by the DME/ECU for safety, data logging, or adaptive tuning features. It is unique in its ability to function as a separate standalone, as well as a parallel module in conjunction with the DME/ECU. The ReFlex provides the most accurate and precise supplementary sequential fuel injection with the ability to control other advanced features all in one place. It brings a new level of control, function, and versatility to tuning any modern-day vehicle. Preset crank and cam trigger for most modern-day BMW engines, as well as fully configurable triggers to be synched on any vehicle application. Configurable to operate on 4, 5, 6, and 8-cylinder engines. 3 Point MAP sensor calibration table makes it configurable for almost any MAP or TMAP sensor. Sequential Port Injection with the ability to sense individual injector failures on 4 to 8-cylinder engines. Built-in Ethanol Content Analyzer. The Re|Flex firmware and XDFs include ethanol compensation tables to scale properly for varying ethanol % based on real-time input from the sensor. 2x Additional Outputs. These outputs have 12x12 resolution tables for control in TunerPro R/T. These can be configured to run as on/off, digital, frequency (25hz), or PID. Boost Control WGDC Methanol Solenoid Control PWM (for use with valves such as the Aquamist FAV and the ProMeth Pulse Valve) Nitrous Solenoid Control PWM Auxiliary fuel pump relay trigger 2x Inputs Ethanol Content Sensor Fuel Pressure Sensor (0-10bar) Oil Pressure (0-10bar) Coolant Pressure (0-10bar) EGBP/EMAP (0-10bar) CANbus (not required) enabled communication for the transmission and receiving of digital signals for fully DME/ECU integrated control of external modifications. The CANbus communications also allow for data and errors to be transmitted to and from the vehicle's engine control computer in order to add safeguards and implement engine trips and fail safes. Logging via OBDII is still fully functional and is not affected at all by the communication with the Re|Flex. Some of the developments underway include: Error reporting to and from factory ECU for unparalleled safety Output WGDC by converting an EWG signal to a more conventional DC output for controlling standard 3port and 4port boost solenoids for use with external WG’s The ability to datalog non-factory parameters such as ethanol content, additional pressure sensor, PI IDC, and more! These features make the Re|Flex the most powerful and safest supplementary and auxiliary controller on the market. However, this is only the beginning. As flash platforms find the need for more accessories to control, the Re|Flex was designed to be updated easily by the end user in order to add functionality as it is developed.

The MOTIV ReFlex+ is an Advanced I/O Integration module allowing a level of precise control of auxiliary components. In addition, the ReFlex can incorporate external data into the factory DME/ECU in parallel through optional CANbus integration. Utilizing the CANbus option, multiple digital and analog signals can be used by the DME/ECU for safety, data logging, or adaptive tuning features. It is unique in its ability to function as a separate standalone, as well as a parallel module in conjunction with the DME/ECU. The ReFlex provides the most accurate and precise supplementary sequential fuel injection with the ability to control other advanced features all in one place. It brings a new level of control, function, and versatility to tuning any modern-day vehicle. Preset crank and cam trigger for most modern-day BMW engines, as well as fully configurable triggers to be synched on any vehicle application. Configurable to operate on 4, 5, 6, and 8-cylinder engines. 3 Point MAP sensor calibration table makes it configurable for almost any MAP or TMAP sensor. Sequential Port Injection with the ability to sense individual injector failures on 4 to 8-cylinder engines. Built-in Ethanol Content Analyzer. The Re|Flex firmware and XDFs include ethanol compensation tables to scale properly for varying ethanol % based on real-time input from the sensor. 2x Additional Outputs. These outputs have 12x12 resolution tables for control in TunerPro R/T. These can be configured to run as on/off, digital, frequency (25hz), or PID. Boost Control WGDC Methanol Solenoid Control PWM (for use with valves such as the Aquamist FAV and the ProMeth Pulse Valve) Nitrous Solenoid Control PWM Auxiliary fuel pump relay trigger 2x Inputs Ethanol Content Sensor Fuel Pressure Sensor (0-10bar) Oil Pressure (0-10bar) Coolant Pressure (0-10bar) EGBP/EMAP (0-10bar) CANbus (not required) enabled communication for the transmission and receiving of digital signals for fully DME/ECU integrated control of external modifications. The CANbus communications also allow for data and errors to be transmitted to and from the vehicle's engine control computer in order to add safeguards and implement engine trips and fail safes. Logging via OBDII is still fully functional and is not affected at all by the communication with the Re|Flex. Some of the developments underway include: Error reporting to and from factory ECU for unparalleled safety Output WGDC by converting an EWG signal to a more conventional DC output for controlling standard 3port and 4port boost solenoids for use with external WG’s The ability to datalog non-factory parameters such as ethanol content, additional pressure sensor, PI IDC, and more! These features make the Re|Flex the most powerful and safest supplementary and auxiliary controller on the market. However, this is only the beginning. As flash platforms find the need for more accessories to control, the Re|Flex was designed to be updated easily by the end user in order to add functionality as it is developed.
