Running Ethanol isn’t just about adding power - it’s about control. The moment you move beyond pump gas, fuel composition becomes critical. And without accurate data, even the best setup is working blind. That’s exactly why the MHD ethanol sensor is not optional - it’s essential. At TunePoint, we work with setups where precision matters. Whether you’re daily driving or pushing your build further, you need to know exactly what’s in your tank - not estimate it.

Built for true Flex Fuel control

A proper MHD Flex Fuel setup allows your engine to respond to real fuel content, not fixed assumptions. Instead of running a static tune, your ECU adapts based on actual Ethanol percentage. The MHD Flex Fuel analyzer reads fuel composition in real time and feeds that data directly into your system. No guesswork. No inconsistency. This is how modern ECU tuning should work - dynamic, responsive, and built around real conditions.

Precision where it matters most

Fuel content directly affects ignition timing, boost targets, and fueling strategy. Without accurate input, you’re either leaving power on the table or risking instability. With the MHD Flex Fuel analyzer, your setup has the data it needs to make correct adjustments. When paired with a properly configured MHD ECU setup, the system allows your engine to scale safely with your fuel - whether you’re on pump gas, full Ethanol, or anything in between.

That’s not just more power - that’s usable, repeatable performance.

One integrated system

The MHD Flex Fuel kit is designed as a complete solution. Sensor, analyzer, and software are built to work together without compatibility issues or workarounds.Installation is straightforward, and once active, the system runs continuously in the background - monitoring, adjusting, and optimizing. This is the difference between basic modifications and proper chiptuning.

Built for real-world driving

Fuel quality varies. Across Europe, even the same station can deliver different Ethanol content from one fill to the next. With MHD Flex Fuel, your setup automatically adapts. No need to reflash maps. No need to second-guess your fuel. The system responds in real time, keeping your engine consistent and predictable. That’s critical whether you’re commuting, traveling, or pushing the car under load.

Hardware you can trust

Accuracy matters. That’s why every MHD ethanol sensor and MHD can Flex Fuel analyzer we offer is selected for reliability and precision. At TunePoint, Quality is not marketing - it’s a requirement. These components are designed to deliver stable readings and long-term durability, even in demanding conditions. Because when your tuning depends on fuel data, there’s no room for error.

The difference you feel

The moment your setup starts working with real data, the car behaves differently. Power delivery becomes smoother. Transitions are cleaner. The engine responds consistently, regardless of fuel variation.

You’re no longer compensating for unknowns - your system is working with accurate inputs. That’s the real advantage of a properly configured MHD Flex Fuel kit.

Upgrade with confidence

If you’re serious about running Ethanol, this is the step that brings everything together. With MHD flex fuel, you get adaptive tuning, reliable data, and performance you can actually trust. No shortcuts. No assumptions. At TunePoint, we provide access to proven solutions, fast delivery across Europe, and support from people who understand how these systems perform in real-world conditions.

FAQ

What is an MHD FlexFuel kit?
An MHD FlexFuel kit is a hardware solution that allows your ECU to automatically adjust engine tuning based on the ethanol content in your fuel. The kit typically includes an ethanol sensor and an MHD CAN FlexFuel analyzer that sends ethanol data directly to the ECU for real-time adjustments.
What does the MHD ethanol sensor measure?
The MHD ethanol sensor measures the percentage of ethanol in your fuel. This information is then processed by the MHD FlexFuel analyzer and used by the MHD ECU tune to adjust fueling, ignition timing, and boost according to the ethanol content.
Do I need MHD Tuning tuning to use a FlexFuel kit?
Yes, an MHD Tuning OTS or custom map that supports FlexFuel is required. The MHD FlexFuel system works together with the ECU calibration so the car can safely run different ethanol blends without switching maps manually.
What is an MHD CAN FlexFuel analyzer?
The MHD CAN FlexFuel analyzer is a module that converts the signal from the ethanol sensor into CAN bus data that the ECU can read. This is what enables true MHD FlexFuel functionality and real-time ethanol content monitoring.
Which vehicles are compatible with MHD FlexFuel kits?
Compatibility depends on the specific kit, but MHD FlexFuel kits are available for many E/F/G Series engines such as B48, B58, N55, S55, and some newer G-series models. Always check product compatibility before purchasing.
What are the benefits of using an MHD FlexFuel system?
An MHD FlexFuel system allows you to run pump fuel, ethanol, or any mix of both without changing maps. The system automatically adjusts the tune based on ethanol content, improving performance, safety, and convenience.
