========================================================================== COBB’s Flex Fuel system is here! COBB announces their new Fuel Pressure Sensor and Ethanol Sensor Kit for the 2008-2014 Subaru WRX & 2008-2016 Subaru WRX STI. ==========================================================================
The key to their Flex Fuel system is the COBB Ethanol Sensor Kit. This kit consists of an ethanol sensor along with a converter that translates the signal from the sensor into something your vehicle’s ECU can use. It also includes a harness and replacement fuel lines to make this a true plug-and-play solution.
COBB has also developed a Fuel Pressure Sensor Kit. This will allow users to monitor fuel pressure at the fuel rail on the Accessport V3. In their testing, the Fuel Pressure sensor kit is very important to verify a Flex Fuel car (or any car really!) is running safely. This kit will be a requirement for COBB’s Flex Fuel “Off The Shelf” maps.
What Parts Do I Need for Ethanol? Since E85 has less energy by volume compared to gasoline, your fuel system must be capable of additional flow requirements. Upgraded fuel pumps and injectors can be expected on traditional port injection vehicles. It’s important these upgrades are specifically cordial with ethanol-based fuels. Fuel pumps rely heavily on fuel to keep themselves lubricated. Unlike gasoline, ethanol is not petroleum based. Not only does it not lubricate, it actively cleans lubrication. Aside from the cleaning trait of alcohol, it’s also hygroscopic. This means it pulls moisture from the surrounding air. If E85 sits in the injectors for long periods it can cause them to rust. Rust in injectors when you’re dealing with tolerances of a few thousandths of an inch results in drastic changes in flow rates. Even with stainless internal injectors it’s a good idea to start the car at least weekly if ethanol is in the system to prevent this from happening. Long story short, make sure your fuel system upgrades comply with E85 or you’re gonna have a bad time.
Since there is such a disparity in E85 from station to station and from season to season an ethanol content sensor is necessary. This can be used on certain platforms in conjunction with Accesstuner to account for necessary tuning changes caused by differences in fuel content. As an added bonus, especially if you travel through places where E85 is not available, this sensor will allow you to accommodate any fuel from regular pump gas all the way to E85 and anywhere in between.
