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

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%

The True Flex sensor is easy to install and understand. Takes all kinds of Dino fluid. My MK7 GLI is smoother and responsive with e85 than gas. Buy It!

Highly recommended if you wanting to get big power from your mbq car . Install as far as finding a pin where depend in the ECU harness is a little bit tricky, but besides that straightforward and easy.
