ENGINE COMPATIBILITY
Our TrueFlex sensor harness kit is compatible with all 2015-2021 VW MK7 and Audi 8V 2.0T EA888 Gen 3 engines. The harness kit on its own will not function without a matching IE TrueFlex ethanol tune. Tuning is currently available for select vehicle years and is being expanded now. If you are waiting for tune support to be released for your model year, the kit can be installed ahead of time without an IE TrueFlex tune safely, the stock ECU calibration will ignore the harness input until the tune is flashed (do not run ethanol without the TrueFlex tune on the ECU).
*Supports Audi A3 with all-wheel drive (Quattro) and 2.0T only.
*TrueFlex tuning is currently expanded for North America (NA) ECUs. Rest-of-world (ROW) ECUs (Europe, Asia, Australia, etc.) may not be fully supported. Please contact IE Support before purchasing to verify your ROW compatibility before ordering. Early European Simos12 ECUs (5G0906259) can not be supported.
