Part number: IBR-FLX01-GRFA

This kit is designed to provide a way to data log and monitor the ethanol content of fuel on most new Subaru Vehicles. Our proprietary controller reduces complications by generating its own on board 12V supply to power the sensor. This reduces wiring, installation time and improves reliability. Our system also properly references the ECU 5V power to provide the most consistent and accurate data. We have supplied hose assemblies for both the 2008+ STi and WRX in a single kit to reduce complication and confusion when ordering. The kit also comes with a custom wiring harness that can be detached from the controller to make any troubleshooting and repairs simple and painless.

Since the cars only have two TGV plugs capable of receiving inputs you cannot run our Secondary Injection Controller, Flex Fuel Sensor and Fuel Pressure Sensor kits all at the same time. You can only run a maximum of two of these three items. The SIC can be wired as power only in order to utilize all three but a custom harness must be made.

Compatibility:
2008 - 2021 STi
2008 - 2021 WRX

Works with all fuel management systems but the car must be tuned specifically to run flex fuel.

Key Benefits:

  • Replaceable wiring harness that will be sold separately

  • Automotive grade wiring

  • No need for 12v supply from rear O2 sensor (common failure point)

  • Installation can be done from the top with no need to crawl under the car

  • Properly referenced analog output from ECU 5V for better accuracy

  • Potted housing with solid pin connector for the ultimate in durability

Included in the kit:

Continental Flex Fuel Sensor
Flex Fuel Sensor Bracket
Flex Fuel Sensor Controller
Wiring Harness
Fuel Lines for both the 2008+ STi and WRX

Not the best
Size: 7, Color: Black, Size: 7, Color: Black
They are cute but they have a bit of an odd fit that isn’t great for people with narrow feet. They look too dressy to wear with super casual outfits in my opinion. I think the Ugg golden star sandals are much comfier. If you’re wearing these sandals for a really short time they’d be okay. After wearing them around my house for a little while I decided to return them since they started to hurt my feet.

Not for narrow feet, very lightweight.
Size: 7.5, Color: Black
My feet are slightly narrow; these were not adjustable enough to make secure. Otherwise they are cute. The material feels kind of light, these were my first attempt at UGGs so I'm not sure if that's typical or an actual quality issue. Either way, they don't seem very durable but I can't imagine these are meant for roughing it.

Nice so far.
Size: 6.5, Color: Molasses
Comfy. They were tight the first day across the toes but as I've worn them a couple times they are loosening up. The sole is forming to my foot. These are very much like Doc Martin's from the early 2000s. Not sure about quality since I haven't had them for very long.
