ENGINE COMPATIBILITY

Our TrueFlex sensor harness kit is compatible with all W MK7/MK7.5 and Audi 8V/8V.5 2.0T EA888 Gen 3 engines. The harness kit will not function without a matching IE TrueFlex ethanol tune. The kit can be installed safely ahead of time without an IE TrueFlex tune, as 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. 

AVAILABLE TUNE SUPPORT

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.
