The Ecotune Flex Fuel Kit is a comprehensive hardware solution designed to suit Ecotune Reflex-equipped vehicles on the MQB platform. By integrating a genuine OE Flex Fuel sensor into your fuel system, this kit allows your ECU to monitor ethanol content in real-time. This hardware enables "on-the-fly" calibration adjustments, ensuring your engine always runs at the perfect ignition angle and fueling split regardless of the ethanol ratio in your tank—from standard pump fuel to full E85.

To utilize this kit, your vehicle must be equipped with Ecotune Reflex technology. Proper installation of fuel sensors is critical for both safety and accurate data logging.

This kit is compatible with the 1.8T and 2.0T EA888 Gen 3 engines found in MQB chassis vehicles. It comes complete with quick clips and all necessary fittings.
| Vehicle Platform | Compatibility Notes |
|---|---|
| VW Golf Mk7 / Mk7.5 / Mk8 | GTI, Clubsport, and R Models |
| Audi S3 / TT / TTS | 8V, 8S, and 8Y (Standard & GPF) |
| Cupra Leon / Formentor | All MQB 1.8T and 2.0T Variants |
IMPORTANT: For vehicles deciding to add Flex Fuel capability, the OEM port injectors may reach their capacity. We recommend pairing this kit with the Ecotune MQB Port Injector Upgrade for maximum performance.
