Haltech Flex Fuel Composition Sensor for 3/8 (GM Spring Lock) Fittings w/Plug & Pins

Haltech is well-known for its advanced engine management systems, and this Flex Fuel Composition Sensor is a key component for anyone looking to fine-tune their fuel delivery. This sensor is designed to accurately measure the ethanol content in your fuel, allowing your engine management system to make real-time adjustments for optimal performance and safety. It's built with 3/8 inch GM spring lock fittings, which are a common and reliable connection type, making installation straightforward in many custom setups. The included plug and pins ensure you have what you need to integrate it into your wiring harness.

When you're running a flex fuel setup, knowing the exact ethanol percentage is critical. Too much ethanol without proper tuning can lead to engine damage, while running less ethanol than expected means you're not taking advantage of the higher octane and increased power potential. This sensor takes the guesswork out of it, providing the data your Haltech ECU needs to adjust fuel maps, ignition timing, and boost levels on the fly. It's a well-built piece that offers a practical solution for serious tuners and fabricators working with E85 or other ethanol blends.
