Why You’ll Love the IE TrueFlex Sensor Harness

  • This is a must-have for anyone running IE TrueFlex tunes on your VW or Audi.
  • Switching between 91 pump gas and full E85? You can do it on the fly.
  • Designed specifically for VW MK7 and Audi 8V EA888.3 2.0T engines.
  • Real-time sensor data sent straight to your IE ECU for spot-on adjustments.
  • Everything you need for a straightforward install is included.

What’s in the Box?

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

Installation Details

This kit is pretty much plug-and-play, but you'll need to disconnect some factory fuel lines. It’s best to take your time or let a pro handle it if you’re not comfortable. The harness is cut to the right lengths for a clean, factory-like installation, so no worries there.

Engine Compatibility

If you've got a 2015-2021 VW MK7 or Audi 8V with a 2.0T EA888 Gen 3 engine, this harness is for you. Just a heads up, it won’t do its magic without the matching IE TrueFlex ethanol tune. Tuning is available for specific model years, and they’re adding more all the time. If your model year isn’t supported yet, you can still install the kit. The stock ECU will ignore the harness input until you flash the tune, but don’t run any ethanol without that TrueFlex tune in place.

Who is Integrated Engineering?

Integrated Engineering was founded in 2007 in Salt Lake City, Utah. It was started by two brothers Peter and David Blais. The two shared the same passion for racing, and this has jumpstarted the two to create Integrated Engineering. 

The company specializes in manufacturing performance products such as rods, camshafts, valve trains, and Billett accessories. Today, they have become a household name when it comes to performance.

German Car Experts

Integrated Engineering focuses on producing performance products for Audi and VWs. As the experts in these platforms, they are able to pinpoint exactly what parts need to be improved to bring out the best in those vehicles. The company considers not only the performance gain but its reliability as well. Their goal is to turn these vehicles into a better performing machine without compromising its reliability.

Attention to Detail is the Key

To create top quality products, the company carefully studies each design detail using specialized software. This enables them to fine-tune the design before it goes to actual manufacturing. They first test their design in ABS plastic to ensure that all measurements are accurate and on the spot. Once everything has been checked, their performance products are then tested in their in-house engine and chassis dyno machine for long hours to test its performance and reliability.

This attention to detail has enabled their parts to perform in extreme conditions and withstand the punishment usually endured during high-performance applications.
