The ReFlex+ is an advanced integration module for performance vehicle tuning and auxiliary component control. With multiple patented technologies, the ReFlex+ is more than just an auxiliary injector controller. It offers advanced features typically found in high-end ECUs—at a fraction of the price. The ReFlex+ is designed to run in multiple control configurations from standalone tuning to full CAN Bus integration and offers unparalleled precision, flexibility, and performance.

NOTE: Select PT-CAN2 for all MHD+ and EcuTek cars with automatic transmissions. For BM3 and all manual transmission cars select PT-CAN.

Advanced Control Strategies

Standalone Mode – No CAN Bus communication required
Integrated CAN Bus – Compatible with MHD, EcuTek, MG Flasher, BM3 and any other tuning platform with the ability to receive and/or send CAN Bus messages.
Advanced CAN Bus – Full integration with EcuTek and MHD+


Precision Sequential Port Injection & More


Originally developed to modernize port fuel injection, the ReFlex+ goes beyond traditional batch-fire controllers by delivering true sequential fuel injection. This ensures fuel is injected at the optimal moment for maximum efficiency, power, and reliability. But it doesn’t stop there—the ReFlex+ is a complete IO control hub designed for performance-driven applications.

Versatile Inputs & Outputs


The ReFlex+ is equipped with a range of inputs and outputs to support flex fuel tuning, boost control, sensor monitoring, and more.

     Inputs:
Sequential Port Injection – Supports up to 8 injectors with fault-sensing feedback
4x Analog Inputs – Compatible with 0-5V and 4-20mA sensors
2x Frequency Inputs – Accepts signals up to 20kHz
Dedicated Flex Fuel Input – Reads ethanol content for real-time flex fuel tuning
MAP, Cam, and Crank Sensor Inputs – Essential for engine timing and load calculations
     Outputs:
4x Low-Side Auxiliary Outputs – PWM or digital ground triggers for methanol injection, nitrous, boost control, fuel pumps, and more
12V Switched Outputs – Power additional components with multiple ignition-switched voltage outputs
OEM-Level Integration & Flash Tuning Compatibility


The ReFlex+ seamlessly integrates with leading flash tuning platforms, including MHD, EcuTek, and MG Flasher allowing the factory ECU to directly control ReFlex+ functions. In addition, built-in safety measures are in place to help protect your investment.

Unlock the Full Potential of Your Build


Whether you're looking for precise auxiliary fuel control, advanced sensor monitoring, or the ability to control performance aftermarket components, the ReFlex+ delivers unmatched performance and versatility.

ReFlex+ Advanced I/O Integration for BMW B58 & S58: Unlocking the Next Level of Engine Control

Modern BMW B58 and S58 engines are among the most capable turbocharged powerplants available today. As enthusiasts push these engines beyond factory limits with larger turbos, ethanol blends, methanol injection, and advanced fueling systems, the need for sophisticated engine management becomes increasingly important.

The ReFlex+ Advanced I/O Integration for BMW B58 and S58 engines is designed specifically for high-performance applications. Unlike traditional standalone engine management systems that require extensive wiring modifications, this solution offers a plug-and-play integration approach, simplifying installation while providing advanced control capabilities.

Why Advanced I/O Matters

When power levels increase, the factory ECU can reach its limitations regarding sensor inputs and auxiliary control functions. Advanced I/O systems allow tuners to integrate additional sensors and devices such as:

  • Ethanol content sensors
  • Fuel pressure monitoring
  • Water/methanol injection systems
  • External boost control devices
  • Additional safety monitoring functions

These inputs help maintain reliability while enabling more aggressive tuning strategies.

Benefits for B58 and S58 Owners

One of the biggest advantages of the ReFlex+ platform is its ability to expand the capabilities of the factory ECU without sacrificing OEM drivability. Tuners can implement advanced fueling strategies and monitor critical engine parameters in real time.

For owners running upgraded turbochargers or high-ethanol fuel blends, the additional control and safety features can be essential for maintaining consistent performance under demanding conditions.

Plug-and-Play Convenience

Traditional motorsport electronics often require extensive custom wiring and installation work. The ReFlex+ system is engineered as a plug-and-play solution for BMW B58 and S58 platforms, reducing installation complexity and making advanced engine control more accessible to enthusiasts and professional tuners alike.

Ideal Applications

The system is particularly well suited for:

  • High-horsepower street builds
  • Track-focused vehicles
  • Ethanol and flex-fuel conversions
  • Large turbocharger upgrades
  • Advanced fueling system integrations

Final Thoughts

As BMW tuning continues to evolve, advanced integration systems like the ReFlex+ are becoming a key component of serious performance builds. By combining plug-and-play installation with expanded input/output functionality, the platform provides tuners with the tools needed to safely extract more performance from the already impressive B58 and S58 engines.

FAQ

Does the B58/S58 version require cutting or splicing the factory wiring?
No, the plug-and-play harness is 100% reversible and requires no cutting, crimping, or splicing of the factory wiring. All connections are made through existing plugs, meaning the car can be returned to a completely stock configuration if needed.
What CAN variant should I select for my B58/S58 car?
Select PT-CAN2 for all MHD+ and EcuTek cars with automatic transmissions. For BM3 and all manual transmission cars, select PT-CAN. Choosing the wrong variant can cause communication issues, so confirming your tuning platform and gearbox type before ordering is essential
How is the ReFlex+ configured and is support available?
The ReFlex+ is fully configurable through TunerPro RT and supports both universal and vehicle-specific configurations. Free starter maps and setup guides are available, with additional technical support accessible directly through MOTIV Motorsport.
What auxiliary inputs and outputs does the ReFlex+ provide?
The ReFlex+ includes four additional auxiliary outputs and four additional auxiliary inputs via CANbus, allowing precise control of external components such as boost solenoids, additional sensors, and other aftermarket performance parts beyond what the factory ECU can manage.
Can the ReFlex+ datalog parameters the factory ECU cannot access?
Yes, the ReFlex+ allows datalogging of non-factory parameters such as ethanol content, additional pressure sensor readings, and port injection injector duty cycle, giving tuners access to data that the factory ECU has no visibility of on its own
Is the ReFlex+ suitable for both B58 Gen 1 and Gen 2 platforms?
Yes, the plug-and-play harness is compatible with both B58 Gen 1 models such as the 340i and M240i from 2016 to 2019, and B58 Gen 2 models including the Toyota Supra, M340i, and M240i from 2018 onwards, as well as S58-powered G80 M3, G82 M4, and G87 M2 vehicles.

Simon A.

Plug-and-play lives up to the name. Connected straight to the B58 without any wiring headaches. Just make sure you select the right CAN bus option for your setup - PT-CAN2 for MHD+ auto, PT-CAN for manual or BM3.

Rocco Y.

Installed this on a manual B58 running BM3 - PT-CAN selected and it worked perfectly from the first start. No fuss, no modifications needed. Exactly what this kind of product should be.

Felix K.

The plug-and-play design on the S58 is excellent. Took no time at all to get up and running. CAN selection is straightforward once you read the notes - PT-CAN for BM3 users.

Serhii Y.

Fitted this on my M140i after going Stage 2 and the difference in charge temps is immediately measurable. Heat soak on back-to-back pulls is basically gone. AIRTEC quality as expected - excellent.

Noel Q.

Fitted these on my F90 M5 and the stance transformation is immediately noticeable. Precise fit, clean machining and no play whatsoever on the hub. Solid kit from TunePoint.

Lukas B.

Seamless install on a B58 auto running MHD+. PT-CAN2 was the right call and everything worked straight out of the box. Build quality feels solid and premium.

Daniel R.

Best I/O integration I've used on a BMW platform. True plug-and-play with zero drama. Just pick PT-CAN or PT-CAN2 depending on your tune and transmission and you're good to go.
