• Flex fuel tuning with petrol and ethanol blends
• Automatic fuel, ignition, and boost compensation based on ethanol content
• Monitoring fuel temperature

Compatibility

• Link G4
• Link G4+
• Link G4X
• Link Wire-In ECUs
• Link Plug-In ECUs
• PCLink software

Notes

• Uses one digital input on the ECU
• Installed in the fuel return line between the fuel pressure regulator and fuel tank
