Which ProFlex Commander Option Should You Choose?

Standard Commander

The Standard Commander is the go-to choice for stock or lightly modified vehicles running factory fuel injectors and naturally aspirated setups. If you haven’t upgraded your injectors or added forced induction (like a supercharger or turbo), this is the perfect fit.

• No tuning required
• Seamless flex fuel performance
• Ideal for street-driven and daily performance builds

Commander Pro

The Commander Pro is built for high-performance builds with upgraded fuel systems. If your vehicle has (or will have) aftermarket forced induction or larger fuel injectors (600cc / 60 lb/hr or bigger), the Pro is your move.

• Works with your current setup — and scales as you upgrade
• Recommended for turbocharged or supercharged builds
• Features more precise injector management for controlling big injectors.

Bottom line:
Got boost or big injectors? Go Pro.
If not, the Standard is all you need.

Which Fuel Sensor Do You Need?

Standard Sensor

The Standard Sensor delivers rock-solid ethanol content readings and is great for most stock or mildly modified fuel systems.

• Accurate ethanol % readings
• Reliable performance for daily and spirited driving
• No extra bells and whistles — just works

E-Sense Sensor Upgrade

The E-Sense is designed for modified fuel systems where precision and performance matter most.

• Higher flow capacity for high-horsepower builds
• Adds fuel temperature monitoring
• Unlocks real-time data in the ProFlex Connect app

Rule of thumb:
If your fuel system is stock, go Standard.
If it’s modified, go E-Sense.

Please Note: Cars with a supercharger may require upgrades to the fuel pump and/or injectors to run full E85. Supercharged M5 and M6s should be dyno tested or logged to ensure the fuel system is able to meet the demand of the fuel or blend customers wish to use to ensure safe engine operation. Please contact us for more information.
