OVERVIEW

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).

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!

One of the Best Mods for MK7

Going into this, I was super nervous to try and install it. After some light research it really takes any of the guess work out of it and makes it a super easy install. Hardest part is depinning the ECU connector pin 71, but even then it's super easy! This paired with the ECU tune is absolutely monstrous for MK7. My MK7 R is the most fun car I've ever been in thanks to this.

Don’t wait, just do it!

Time consuming install especially the ecu pin routing but take your time and it’ll look like it was meant to be there all along. Paired this up with an APR HPFP and IE ECU/DSG tune even with my first tank being E50 I can feel the power difference. My only problem was during 4K RPM launch control the car bogs once launched goes from 5K RPM back down to 3K before pulling again. I’m going to try a 3200 launch and see if that makes a difference. Never had the problem before at 4K rpm.

Any octane anytime!

This was a simple and elegant install! Watched several install videos before starting which helped immensely. Great for going to the track for E85 and chevron daily... Don't forget the HPFP though!

True flex and full e85

The install of the harness is pretty straight forward. The true flex tune on full E is insane. Can’t believe how much quicker the car is. 100% recommended for the golf R.
