High quality Flex Fuel kits for the new GR86 /BRZ 2022+ FA24 based platform, as well as the FA20 platform as of November 2024. These new kits are far more powerful and advanced than your traditional flex fuel sensor kit. They are CAN based, connecting to an existing network in the car without hijacking the signal of any OEM sensors or functions.

 

No modifications to any sensors or disabling of any codes are needed in the tuning process of these new kits. We have also made this system plug and play, requiring no permanent modification of any part of the vehicle.

 

With a custom harness that connects to the cars onboard CANBUS network, installation is simpler yet smarter than ever before.

 

Optional extra sensors for fuel and oil pressure monitoring allow you to use your OEM OBD2 port for logging with EcuTek, Racechrono, AIM Solo DL, or other canbus capable loggers.

 

Please be sure to read the full description on this listing below for notices and instructions. DO NOT ASSUME you have an early model based on when you purchased the vehicle. Dates are based off USDM cars so it's best to check regardless if you live outside the US.

 

**While CSG Spec CANBUS FlexFuel kit components are generally kept in stock, due to the customizable nature of the kit, some assembly may be required by CSG before your kit is shipped out. Please inquire before purchasing if you need your kit ASAP**

 

*CSG Spec CANBUS FlexFuel kits are designed for USDM cars and may require additional parts (not supplied) for elsewhere in the world.*

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
