LEADING FEATURES

  • Includes everything needed to install

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

INSTALLATION

This harness kit is fully assembled to proper lengths and includes everything needed to install it in a clean and factory-like installation. Disconnecting and cutting of factory soft fuel lines is required and should be completed with great care or by a professional.  Click here to download the install guide

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

Try alternate install location on left side

After reviewing the instructions and search for a more rigid mounting location, I discovered that the OEM fuel line hold downs molded onto the intake manifold towards the left side (nearest to the HPFP) are the right size and spaced apart appropriately to hold the two ends of the fuel line with the sensor right in between. Having the ability to use any blend of E85 and 91+ gasoline is game changing. Awesome work IE!

Great product needs some improvement

Install was tricky when it came to wiring, wish a de-pin tool came with this kit . The ground wire could have been 3-4inches longer so you can tuck and zip tie it down easier. Other than that very cool product for.

Easy EXCEPT

in my 2016 Golf R, there was a metal shield around the ECU that had to be removed: be ready for either drilling out rivets or chopping metal. other than that, install was straightforward, follow the very simple instructions!

ie true flex e85 stage 2 mk7.5 golf r

Definitely a noticeable difference when switching from stage 2 high torque tune to e85 true flex. Very consistent drag time numbers was found as well. Install was pretty simple but the ethanol sensor doesn’t clip into the intake manifold properly, it’s just slightly too big but overall recommend this product 100%
