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).
