OVERVIEW

This plug and play harness kit is required for IE TrueFlex ECU Tunes for VW and Audi MQB Gen 3 engines. This includes everything necessary for the flex-fuel sensor to send real-time data from your fuel system to the ECU and adjust for any content mix from 91 pump to full E85 automatically. 


Kit includes:

  • (1x) IE TrueFlex Wiring Harness
  • (1x) 2 amp Fuse
  • (1x) Ethanol Sensor
  • (2x) Ethanol Sensor Quick Connect Couplers
  • (2x) Hose Clamps

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).

Does what it needs to do, unlocks more powah baby!

Pretty straight forward install. Not IE's fault but the ECU pin is really difficult to get in the proper spot. Tons of wires going into the ECU harness so it's really nerve racking trying to move them all out of the way. The kit itself was great though and install is super clean.

Good Quality and Easy Installation

Detailed Instructions provided on the IE website for download. Total installation time was about an 1 1/2 hours from start to finish. Ver happy with the cleanliness of the install, looks factory. E85 is the way to go.

The missing pieces on MK7

This is what is missing from factory. The packaging and installation instructions are on point.

Amazing Product & Easy Install

The TrueFlex tune is a game changer!

The installation is a bit time consuming but straightforward, if you want things to look OEM and for things to function properly.

Once installed and the tune uploaded, I filled up the tank with that wonderful corn juice, and HOLY MOTHER OF CORN! The ease of use, cost, and performance are 1,000% worth it!
