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.

d for improved injector function in forced induction and large injector environments.
