The ProFlex Commander for 1997-2015 GM LS Engine Swap (LSx) is a plug-and-play performance E85 flex fuel system giving your vehicle the ability to run E85, gas, or any blend right out of the box without the need to tune or switch maps. Please ensure that your build has injectors and a fuel pump setup that are capable of flowing full E85 before you install the system and begin using E85 fuel.

Due to the nature of swapping an engine there are many injector configurations. Please choose the configuration that you need for your build.

Please contact us if you if you have any questions. We are happy to assist you.
