{"product_id":"flx01-flex-fuel-upgrade-kit","title":"FLX01 Flex Fuel Upgrade Kit","description":"The I Build Race Cars FLX01 Flex Fuel Upgrade Kit provides a streamlined solution for data logging and monitoring ethanol content in your Subaru's fuel system. This kit is engineered to reduce installation complexity by having its controller generate its own onboard 12V supply, eliminating a common failure point associated with tapping into the rear O2 sensor.\n\nThe upgrade kit ensures accurate and consistent data by properly referencing the ECU's 5V power. It features a replaceable wiring harness made with automotive-grade materials and a potted housing with a solid pin connector for enhanced durability. This kit is ideal for users with existing unreliable flex fuel systems or those building custom fuel systems who want the flexibility to source some components independently.\n\nIncluded in this kit are the Flex Fuel Sensor Controller, a 3-pin TGV plug\/wiring harness, and hardware for mounting the controller. It is important to note that this upgrade kit will not work with the latest tuning software changes and requires the vehicle to already be tuned specifically for flex fuel. While retuning may not be necessary if replacing a similar brand's flex fuel controller, tuning specifically to run flex fuel is mandatory for operation. Additionally, the controller should not be mounted directly on the intake manifold. Users should thoroughly read the installation instructions prior to installation. Due to limited TGV plugs, only two of the following can be run simultaneously: Secondary Injection Controller, Flex Fuel Sensor, and Fuel Pressure Sensor kits; a custom harness is required to run all three.","brand":"iBuildRacecars","offers":[{"title":"Default Title","offer_id":52688784589112,"sku":"IBR-FLXUPG-3PIN","price":439.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663183231.webp?v=1784895902","url":"https:\/\/store.motormia.co\/products\/flx01-flex-fuel-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
