Give your 3.6L Chrysler 300 the ability to run gasoline, E85 or any mix of the two without changing tunes every time you change fuel. The ProFlex Commander reads the actual ethanol content and adjusts injector operation as you drive.
On a stock or mildly modified naturally aspirated Pentastar with factory injectors, the Standard Commander is the right setup and does not require a separate E85 tune. Advanced Fuel Dynamics reports 7-10% more wheel horsepower and torque on E85, with actual gains depending on the car, fuel and existing modifications.

Emissions Information
The ProFlex Commander does not remove or replace emissions equipment. It reads the ethanol content in the fuel and electronically adjusts injector operation so the engine can run gasoline, E85 or any mixture of the two.
Advanced Fuel Dynamics does not publish a CARB Executive Order number for this kit. Redline360 cannot ship this product to California for use on pollution-controlled vehicles.
Pairs Well With
- K&N Cold Air Intake for Chrysler 300 3.6L V6: Add more airflow and a stronger Pentastar intake sound with a Chrysler 300 cold air intake designed for the 3.6L V6.
- Borla Catback Exhaust for Chrysler 300 3.6L V6: Give the V6 a deeper exhaust note and choose between Borla’s S-Type and louder ATAK sound levels. Fits 2015-2021 models.
- AEM 340LPH E85-Compatible Fuel Pump: A universal high-flow pump for modified or forced-induction E85 builds that need more fuel capacity. This is not required for a stock ProFlex installation and may require changes to the factory fuel-pump assembly and wiring.
About Advanced Fuel Dynamics
Advanced Fuel Dynamics started in 2014 after its founder saw how much the ethanol content in pump E85 could change from one fill-up to the next. The ProFlex Commander was developed to measure the actual blend and adjust injector operation in real time instead of assuming every tank contains the same percentage of ethanol.
Advanced Fuel Dynamics develops its flex-fuel systems in Texas and tests its products on the street, track and dyno.
Redline360 only sells genuine and authentic Advanced Fuel Dynamics products.
