OverviewPort Injection Data
Port Injection Data
Inside MG Flasher.
Motiv ReFlex integration was introduced with Custom Code v7.2. It allows the DME to communicate with a supported ReFlex controller over PT-CAN, giving MG Flasher access to selected data from the auxiliary fueling system.
ReFlex can support port-injection strategies and provide useful inputs such as ethanol content and low-pressure fuel pressure. The MG Flasher app can log supported ReFlex parameters, while Custom Code can use selected fault information for protection and diagnostics.
What the Integration Adds
DME Communication
Custom Code communicates with a configured ReFlex controller through PT-CAN.
App Logging
Selected ReFlex status, fueling and sensor parameters can be recorded in MG Flasher.
Fault Awareness
Supported errors can create Custom Code DTCs and trigger MGF protection when enabled.
System Flow
One Connected Fueling System.
The ReFlex controller and DME exchange supported data through a correctly configured PT-CAN connection.
01
HardwareReFlex Controls PI
The Motiv ReFlex controller manages the supported auxiliary port-injection system and connected sensors.
02
NetworkPT-CAN Communication
ReFlex is connected to PT-CAN and configured to use a supported CAN bus identifier.
03
Custom CodeDME Reads ReFlex Data
Compatible MG Flasher Custom Code receives selected status, ethanol, pressure and PI information.
04
MG Flasher AppLog and Diagnose
Supported parameters and Custom Code DTCs can be reviewed through MG Flasher logging and diagnostics.
Available Data

Configuration RequirementsCorrect Hardware.
Correct Hardware.
Correct Network Setup.
The integration depends on both vehicle compatibility and a correctly installed ReFlex system. Configuration errors can produce invalid data, communication conflicts or protection events.
01
Custom Code v7.2+A compatible Custom Code version must be available and installed for the ECU.
02
PT-CAN ConnectionThe ReFlex system must be connected to the vehicle’s supported PT-CAN network.
03
Supported CAN IDConfigure ReFlex for one supported identifier: 0x334, 0x00EC or 0x04CB.
04
Universal CAN Bus PatchApply the Universal canbus patch and do not combine it with other CAN bus patches.
CAN Configuration
Choose the ID used by the installed setup
Selected Example
0x334
Use the identifier configured for the actual ReFlex installation. If logged data appears incorrect, check for a CAN ID conflict.
!
Use one CAN patch
Apply the Universal canbus patch without any additional CAN bus patches.

Fueling EcosystemReFlex Can Support
ReFlex Can Support
More Than Port Injection.
A compatible ReFlex installation can also provide ethanol-content and low-pressure fuel-pressure information. These inputs can complement supported MG Flasher Flex Fuel and protection strategies.
ReFlex is not required for every Flex Fuel setup, and installing ReFlex does not automatically enable Flex Fuel Blending. The vehicle still needs the correct Custom Code, calibration, sensor configuration and fuel-system hardware.

Compatibility
Check the Complete Setup.
Availability depends on the engine platform, ECU software, Custom Code version, ReFlex hardware and network configuration.
Vehicle & Engine
Start with the relevant Engine or Vehicle Page and confirm that Motiv ReFlex integration is listed for the platform.
ECU Software
The ECU software must support a compatible Custom Code v7.2 or newer release.
Installed Hardware
The ReFlex controller, PI system and any sensors must be correctly installed and configured.
CAN Configuration
PT-CAN wiring, CAN ID and the Universal canbus patch must match the supported setup.
FAQ
Motiv ReFlex Integration FAQ.
Common questions about ReFlex communication, logging, configuration and protection in MG Flasher.
What does Motiv ReFlex integration do in MG Flasher?
It allows compatible MG Flasher Custom Code to communicate with a configured Motiv ReFlex controller and expose selected PI, ethanol, pressure, auxiliary and status information to the app.
Which Custom Code version is required?
Initial Motiv ReFlex support was added in Custom Code v7.2. The exact available version still depends on the vehicle ECU software.
How does ReFlex connect to the DME?
The supported setup uses the vehicle PT-CAN network. The ReFlex controller must use a supported CAN ID and the correct Universal canbus patch.
Which CAN IDs are supported?
The current documentation lists 0x334, 0x00EC and 0x04CB. Use the ID configured for the actual installation and avoid conflicts with other modules.
Can MG Flasher log port-injection data?
Yes. Compatible Custom Code can expose parameters including raw and post-factor PI duty cycle, ethanol PI scaling, system status and auxiliary outputs.
Can ReFlex provide ethanol and low-pressure fuel data?
A compatible ReFlex setup can report ethanol content and low-pressure fuel pressure, which may be logged and used by supported Custom Code strategies.
What happens if a ReFlex fault is detected?
When the relevant protection is enabled, MG Flasher can enter MGF Limp Mode, prevent boost, blink the CEL slowly and record a Custom Code DTC.
Does Motiv ReFlex automatically enable Flex Fuel?
No. Flex Fuel Blending still requires compatible Custom Code, a correctly prepared calibration and the required sensor and fuel-system configuration.
