Installed this on my F30 340i with MHD Stage 2+ and the difference is incredible. The ethanol content reading is accurate and the car adapts flawlessly between pump gas and E blends. Plug-and-play setup made installation much easier than expected.

Great product for anyone serious about flex fuel tuning on BMW F-series cars. The sensor responds quickly and integrates perfectly with MHD. Been daily driving it for months with zero issues.
Very impressed with the build quality and fitment. I’ve tried other ethanol solutions before and this is by far the cleanest setup. No leaks, no CELs, and fuel trims stay stable even on higher ethanol mixes.
If you’re running an upgraded HPFP and ethanol blends, this kit is a must-have. The car feels more responsive and consistent, and having real-time ethanol data is extremely useful. Highly recommended for B58 owners.
Excellent quality kit with everything included for a clean install. I was worried about tuning compatibility, but it worked perfectly with my MHD setup right away. The live ethanol readings give great peace of mind when switching fuels.
Bought this for my M4 and it has been flawless so far. Installation took about an hour on jack stands and the quality of the hoses and connectors is excellent. Definitely worth it if you run ethanol blends regularly.
