Reflex+ FULL KIT BMW B58 kit (inc. injectors)

All included – Reflex Plus kit for BMW B58 or S58 engines with everything you need for Port Injection control

MOTIV ReFlex+ is a versatile controller that allows precise and flexible control of auxiliary systems such as WMI water meth injection, intake manifold port injectors, fuel pumps, relays and much more. When your build reaches the next level, Reflex Plus becomes the natural choice. The unit has become especially popular among BMW tuners across various engine platforms, including the B58 and the newer S58 engines.

We have bundled the most common components into one complete package. In addition, you only need either a Port Injection spacer plate between the intake manifold or an intake manifold prepared for injectors. See our selection including F Essentials and Wagner Tuning products.

What the package includes:

1100cc Bosch EV14 injectors, matched set
Genuine and flow-tested Bosch EV14 injectors with 34mm O-ring spacing and 1060cc output at 3 bar. USCAR connector.

Plug-and-play B58 harness for Reflex
No splice connectors or guesswork, ready-made plugs for x58 engines.

0–10 bar pressure sensor for the Motiv system
Most tuners require a pressure sensor to be installed before tuning the Reflex+ system. The sensor is typically installed in the fuel line for safety strategies, for example in the event of fuel pressure drop. It can also be used to measure other fluid pressures such as oil pressure.

Convenient quick connector for pressure sensor installation for 5/16" line
Quick connector with 1/8 branch port. The adapter snaps into the factory-style fuel line connectors for an easy and clean installation.

Ethanol sensor and 360 degree quick connector for the fuel line (optional)
Allows ethanol content data to be transmitted to the CAN bus for ECU use via the Reflex system.

Ethanol sensor wiring harness (optional)
Cable between the Reflex Plus unit and the ethanol sensor.

MOTIV Reflex Plus system

• Advanced controller for Port Injection auxiliary injector systems
• Supports four AUX outputs and four AUX inputs
• Can be integrated into the CAN bus and add additional channels for ECU use

Auxiliary injector control, PI Port Injection
As power levels increase, direct injection often becomes a bottleneck. Reflex Plus enables intelligent and adaptive control of auxiliary injectors using strategies such as batch, semi-batch or sequential.

Reflex Plus is suitable for engines up to 8 cylinders. A professional tuner can calibrate it for nearly any engine type by correctly defining camshaft, crankshaft and MAP signals. Universal base maps and limited vehicle-specific calibrations are available.

Optional outputs

• Water meth injection, WMI
• Nitrous systems
• Standalone boost controllers
• Fuel pumps
• Relays

Optional inputs and CAN integration

• Fuel pressure
• Exhaust backpressure
• Oil pressure
• Other fluid pressure
• Crankcase pressure

This integration is supported on several popular tuning platforms such as BMW MHD Flash and BM3.
