What Is A Flex Fuel Kit For The 6th Gen Camaro?

flex fuel kit for the 6th Gen Camaro allows your car to run on both traditional pump gasoline and ethanol blends like E85. The kit adds a flex fuel sensor and essential wiring that communicate with your Camaro’s ECU to adjust fueling based on the ethanol content in the tank. This gives your engine the ability to safely and efficiently adapt in real-time to different fuel types.

At Griffin Motorsports, we’ve designed our flex-fuel kit for 6th-gen Camaros to be plug-and-play. Whether you're daily driving or heading to the track, this upgrade opens the door to more performance potential without sacrificing drivability. It's a popular first step for enthusiasts looking to take advantage of ethanol’s higher octane and cooler combustion properties.

Why Upgrade To A Flex Fuel Setup?

Upgrading your 6th Gen Camaro to a flex fuel setup is more than just a fuel change. It’s a performance-forward decision that can unlock serious potential. Let’s take a closer look at why more Camaro owners are making the switch:

Higher Octane, More Power

E85 fuel contains a higher octane level than standard pump gas, allowing for more aggressive tuning. That means your engine can safely run increased timing and boost, which translates directly into more horsepower and torque when properly tuned.

Cooler Combustion Temperatures

Ethanol burns cooler than gasoline, reducing overall combustion temperatures. This leads to lower intake temps and helps prevent detonation, which is key to maintaining engine health during high-performance driving.

Real Flexibility At The Pump

A flex-fuel setup allows your Camaro to automatically adjust to varying ethanol content. Whether you're filling up with 93 octane or full E85, the system adapts without any manual changes, giving you freedom to choose based on availability or driving goals.

Benefits Of E85 For Your Camaro

E85 offers more than just an alternative fuel option. It delivers measurable performance and efficiency benefits for your 6th Gen Camaro. Here's why it's become a go-to for enthusiasts looking to push their builds further:

Increased Horsepower Potential

Thanks to its high ethanol content, E85 supports more aggressive timing and higher boost levels without knocking. This creates a noticeable increase in power, especially when tuned properly alongside other mods. We recently saw a 75rwhp gain when tuning our car from pump 91 to E60 on the dyno. With gains like that it’s no wonder why E85 is known to be the best bang for your buck when it comes to performance mods. 

Improved Engine Cooling

E85 has natural cooling properties that help lower combustion temperatures. This means your engine runs cooler under load, reducing heat soak during repeated pulls or track sessions. These cooling effects also allows for more timing advance, which aids in power improvement. 

Cleaner Combustion

Ethanol burns cleaner than gasoline, producing fewer carbon deposits in the combustion chamber. Over time, this can contribute to better long-term engine cleanliness and improved sensor performance.

Cost-Effective Power Gains

While fuel economy may decrease slightly with ethanol blends, the power-per-dollar benefit often outweighs the trade-off. Our e85 Camaro fuel upgrade provides a straightforward path to more performance without needing major internal engine work.

How Our Flex Fuel Conversion Kit Works

Our camaro e85 conversion kit is designed to integrate seamlessly with the 6th Gen Camaro’s factory systems. It’s engineered for straightforward installation and real-time fuel adaptability. Here's how each part of the setup comes together:

  • Flex Fuel Sensor Integration: At the heart of the kit is a flex fuel sensor that measures the ethanol content in your fuel. This sensor sends data to your ECU, allowing it to adjust fuel trims, timing, and other parameters based on the ethanol percentage.

  • Plug-and-Play Harness: We’ve developed a wiring harness that connects directly to your existing fuel system components. No splicing or complicated rewiring, just a clean install that maintains OE functionality and reliability.

  • ECU Calibration Compatibility: The system works in tandem with a flex-fuel-capable ECU tune. Once installed, your Camaro will automatically adjust fueling maps depending on the fuel mixture in the tank, eliminating the need to manually switch tunes or fuels.

  • Reliable, Tested Performance: Our camaro flex fuel sensor kit has been tested across a wide range of builds, from lightly modified SS models to high-boost ZL1s. It is a proven solution that supports both everyday driving and track-level demands.

  • Quick Connect DYME PTFE Hose Fittings: Our camaro flex fuel sensor kit has been made more reliable and easier to install thanks to our partnership with DYME. No more hoping you tightened those fuel lines enough. Now you simply clip and go to a faster and safer installation.

Most installations can be completed in under an hour with basic hand tools. Our camaro flex fuel sensor kit has been made more reliable and easier to install thanks to our partnership with DYME. No more hoping you tightened those fuel lines enough. Now you simply clip and go to a faster and safer installation. 

Factory ECU Integration

Once installed, the sensor communicates with the ECU to relay ethanol content in real time. If you’re running a compatible flex fuel tune, the ECU will instantly adapt fueling and ignition timing for optimal performance based on your blend.

Diagnostic-Ready And Fully Reversible

Our kit retains your vehicle’s OEM diagnostic capabilities, so you can still scan for codes or monitor fuel system behavior through your tuning platform or aftermarket gauges like our zl1 gauges. And if needed, the setup is fully reversible without permanent changes to your car.

Tuning Requirements For A Flex Fuel 6th Gen Camaro

A flex fuel kit is only part of the equation. To safely run ethanol blends, the ECU must be calibrated to interpret ethanol content data and adjust fueling, ignition timing, and cold-start behavior accordingly. Without proper tuning, the benefits of E85 cannot be fully realized.

Flex Fuel vs. Single-Fuel Tunes

Unlike a fixed E85 tune, a flex fuel tune allows your Camaro to adapt automatically as ethanol content changes. This means you can mix fuels without concern, and the ECU will respond appropriately without driver input or map switching.

Supporting Fuel System Considerations

As power levels increase, additional fuel system upgrades may be required. High-output builds often benefit from upgraded injectors or fuel pumps to maintain proper fuel delivery at higher ethanol percentages. These supporting components help maintain consistency and reliability under load.

Professional Calibration Recommended

While the hardware install is straightforward, tuning should always be handled by an experienced Camaro tuner. Proper calibration improves drivability, protects engine components, and ensures your flex fuel setup performs as intended across all driving conditions. Bundle and save with our remote tuning hardware packages that utilize HP tuners MPIV.4 interface and the much needed AEM's X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0333)
