If you recently unlocked and tuned your BMW M4 and are planning on running flex fuel, you’re probably wondering how to get the proper ethanol blend without guessing.

In this video, I break down exactly how to dial in your ethanol content the right way using MHD on my tuned G8X M4.

I’m running a custom tune with the MHD Flex Fuel kit, and I’ll show you:

• What you need before running E85
• How to check your current ethanol content in the MHD app
• How to calculate the correct mix
• How to avoid running too much or too little ethanol
• Why guessing your blend can hurt performance

If you’re tuned on MHD and running flex fuel, this is the correct way to get your E content dialed in.

My setup:
– 2025 BMW M4 Competition xDrive (G8X)
– MHD custom tune
– MHD Flex Fuel kit
– Ethanol blend setup
