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 havent 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 isstock, go Standard.
If its modified, go E-Sense.
