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: The 4.6 V8 SN95 and 4.6 V8 S197 engines require upgraded injectors to safely run full E85. We recommend 42lb Ford Racing injectors which can be purchased from many vendors.

The ProFlex Commander product line is backed by a limited 12 month warranty. Learn more.
