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 . ProFlex Connect App : With the free PROFLEX Connect app you can connect your smartphone to your PROFLEX Commander and view your vehicle’s ethanol content in real-time, locate and navigate to E85 pumps near your location and run system monitoring and diagnostics.
