TrueFlex Ethanol Content Sensor Kit

The Integrated Engineering IEELCK3 TrueFlex Sensor Kit is an essential component for converting your B9/B9.5 Audi 2.0T engine to a flex-fuel setup. This kit provides the necessary sensor and harness to enable reliable, real-time ethanol content readings, allowing your vehicle to seamlessly adapt and run on a range of fuels from premium 91/93 octane to E85 and any mixture in between when paired with the iE TrueFlex tune. Ethanol, known for its high-octane properties and knock resistance, can significantly boost power. To safely harness this potential, the B9 2.0T's fuel system requires specific upgrades. The TrueFlex Sensor Kit, in conjunction with the iE HPFP MQB Internal Performance Kit and specific OEM components like the VW MK7 2.0T vacuum pump housing, ensures the necessary fuel delivery for optimal performance on ethanol blends. Installation is guided by a step-by-step manual, and users can monitor their ethanol content in real-time via the PowerLink app. **Important Fitment Details:** This TrueFlex tuning system is compatible exclusively with 2017-2020 2.0T model years and is incompatible with 2021+ ECU variations. Furthermore, it is compatible only with Quattro (AWD) models and is incompatible with front-wheel-drive (FWD) vehicles. TrueFlex tuning is intended for North American models and is not supported for Rest-of-world (ROW) ECUs.
