Show original supplier description
The eFlexPlus E85 conversion kit is designed for drivers seeking enhanced vehicle performance and economy without requiring advanced tuning expertise. This kit provides an accessible pathway to basic engine optimization, offering access to the eFlexApp and eFlexTuner software for sophisticated adjustments. With eFlexPlus, users can fine-tune their engine's air-fuel mixture across different RPM ranges, leading to improved performance and fuel economy when running on ethanol fuels. The system also features automatic cold start technology, which adjusts engine start-up based on ethanol content and engine temperature, with adjustable presets or fully personalized custom profiles available through the eFlexApp and eFlexTuner software. The control unit is waterproof (IP68 rated) and connects wirelessly via Bluetooth LE to the free eFlexFuel app, available on the App Store and Google Play. The system offers self-diagnosis with a fault code memory and comes with a two-year limited warranty. This eFlexFuel system is sold for competition and off-road use only, as it is pending U.S. emissions certification. It is compatible with a wide range of Toyota and Lexus models from 2003-2019, including various Prius, Yaris, Tundra, 4Runner, Land Cruiser, Sequoia, FJ Cruiser, Tacoma, RX400h, CT200h, Camry, NX 300h, and RAV4 variants with specific engine configurations.
