TrueFlex Sensor Harness Install - Integrated Engineering VW/Audi MQB

[@erichoward5190]

The best video I’ve seen on installing the E85 kit from integrated engineering on KZbin! Wonderful job.🎉

[@Vaguh]

Thank you! It was a lot of work and I’m proud of it. Yeah, maybe it’s a bit longer than it needs to be, but I hate when people leave out the important steps or things to consider. Cheers!

[@hyper8545]

Nice work. I'm glad IE is putting out e85 products. Its great fuel option and I wana see more stuff available for our German cars for us that can get the fuel regularly. We definitely need the sensor that reads the content tho it makes the process much easier for daily use.

[@Vaguh]

Thank you! I just wish e85 was more available in my own area.

[@07BSPtC]

Same. Looking to do this on my car. Would like dedicated e85 tune but don’t want to deal with testing fuel quality and not sure I can trust my wife to find e85 and worry she will use 91 octane.

[@dominicnaples88]

this might be the best install video ive ever seen

[@Vaguh]

Haha, wow. Thank you! Much appreciated.

Fellow MK7 Golf R owner from PDX here! Hello! Great content!

[@Vaguh]

Hello! Hit us up if you’re ever in the Seattle area! Lots of good MK7 R’s in PDX!

[@Mr_Hustles]

Waiting for my kit to arrive currently. Just wanted to say thanks for making such a detailed video. Seriously, youre the man, thank you for taking the time.

[@Vaguh]

You got it! Glad it was helpful. Keep an eye out for more.

[@Vaguh]

Did you get it and install?

[@Mr_Hustles]

@@Vaguh have it but it's been to cold to wrench. My garage isn't heated. Plus, it sounds like there is a delay on the software anyhow.

[@Mr_Hustles]

@@Vaguh are you currently able to view ethanol content with your OBDeleven? If so, how? Got the install done tonight and wanted to ensure it was functioning correctly.

[@Vaguh]

@@Mr_Hustles The data isn’t enabled to be viewed until the TrueFlex tune is flashed. I was hoping to do the same, but I confirmed with IE that this is the case. I’m sure there’s a way to code it, but idk how and not sure what impacts that could have. Congrats on getting it done! Now we wait.

[@MeltingRubberZ28]

Considering going with IE on my GLI. They haven't come out with this setup for the 19+ cars yet, but I'll subscribe to get educated on the process. Thanks for vids like this!

[@Vaguh]

Thanks for stopping in! From what I understand the process should be identical. Good luck on the GLI! -Adam

[@MeltingRubberZ28]

Watching the video now. I'm really good at breaking those tabs. Glad I'm in good company 👍

[@Vaguh]

@@MeltingRubberZ28 😆 I should keep a hair drier nearby just for the plastic tabs I’ll probably break.

[@MeltingRubberZ28]

@@Vaguh I presume you've been running the trueflex tune for some time now? How do you like it?

[@Vaguh]

@@MeltingRubberZ28 Stage 1 TrueFlex isn’t ready yet so I haven’t tried it yet. I’m going to be jumping back to stage 2 soon and giving it a go then.

[@SH-zv2wy]

Dude; awesome; great video. Thanks for taking the time to show all the cutting and wiring details; very helpful.

[@Vaguh]

Thanks for the feedback! Glad the details were helpful for you. Exactly why I enjoy making these kind of vids. - Adam

Solid video man, really made my install a breeze!

[@guillenrey830]

Hey man love this channel... just found it and your windshield video is clutch! I will be calling Mark in a few hours! If I see a white R rolling around Shoreline I hope its you!

[@Vaguh]

Mark is the man! Thanks for following along and hope to see you around sometime!

Great video! Will it be the same install with an Audi S3?

[@Vaguh]

Thanks! Should be identical for the S3.

[@VAGSPECIALIST]

Where did you connect the white color wire??

[@dksaevs]

WOW another GREAT Video. BTW when i ordered my FUELIT kit i ordered the RAW output just so i could do the same as what you've done.

[@Vaguh]

Thank you for the feedback. I didn’t totally understand the output options for the Fuel-It device so I just crossed my fingers and picked one.

[@dksaevs]

I had emailed IE and had asked what sensor they use/recommend (See Reply below). Waiting for my FuelIt to show up today or Monday, then I'll have to wait a little while longer before my friend's son returns from collage to help with the installs. I promised that I'd show him how all of the new mod's work together to make a "hot hatch" a little hotter. BTW I'm having (C.V.) watch YOUR posts to KZbin because it's apparent that you take pride in your workmanship (therefore IMO worth watching). Rob H. "Zain (Integrated Engineering) Nov 24, 2021, 11:42 AM MST" Hey Robert, We use the AcDelco 13577429 sensor. Best regards. Integrated Engineering

[@Vaguh]

@@dksaevs From what I’ve seen, everyone uses the same ethanol sensor across every make of car. That’s great you’re saving the work for when your friend’s son can help and learn. Thanks for the kind words and hope I get to keep showing and helping people through these projects!

[@maniirdzjr24]

nice. this direct connect kit to the ecu has me over The pricey fuelit kit . So the content will be displayed using the obdeleven?

[@Vaguh]

Yes, you will be able to see content via OBD11, but it only becomes enabled once you load the TrueFlex tune from IE. So don’t get this thinking it’s a cheaper way to see ethanol content if you don’t plan doing IE’s TrueFlex tune.

[@LastHumansGarage]

ill admit my fuel-it kit and their app annoys me much. This never used to happen, but lately when i press connect on the app it never gives me a number for 3-4 tries.. then it finally connects. and their calculator leaves a LOT to be desired, its a pain.

[@LastHumansGarage]

and the fact that they charge you for a shitty app.. thats just the frosting. ok im done ranting.

[@daydream2818]

Thank u i was going crazy locating number 71 🤦‍♂️did u confirm that its the right hole number or the file for ur car didnt come out yet?

[@Vaguh]

I’m 100% certain I got the right pin, but you’re right the file hasn’t come out for my car yet. Without the file, the ethanol channel/bit is not enabled, so I couldn’t see anything in my OBD11 yet. I heard I might get a chance to beta test soon!

[@RhoadsChristopher]

Did you do anything to keep you hood insulation from curling? I can't seem to get mine to stop looking like a banana

[@Vaguh]

Yes I did! Maybe I should make a Short on that. I used black zip ties on the bottoms left and right to keep them tied to the hood. It isn’t ideal, but the easiest solution I could come up with and they haven’t melted from the turbo heat yet. Send me a message on IG @itspronounced_va_guh or email us and I’ll send you a pic or vid.

[@AksmAl]

Can you install the IE Ethanol sensor with a custom tune or does it need to be IE tuned ?

[@54jumpman]

So wait both sides are power where you installed the 2 amp fuse IE supplied?

[@Vaguh]

Both sides of what? If you’re asking about the fuse there is one side of the fuse that already has power existing in the box. We are just taking advantage of the empty slot. The fuse links from the existing power to the power wire from the ethanol sensor you insert into the fuse box.

[@daydream2818]

So for the ecu pin i count 2 from bottom to top then 9 from left to right or 8? U kinda moved the camera real quick there lol , thanks

[@Vaguh]

There are 21 pins in each row, so part of what you said gets you to the right spot. 4th row down begins with pin #64 on the left side, so it would be easiest to count from there. You can double check by counting backward from #85 in the bottom left.

[@daydream2818]

@@Vaguh alright thank u for the great detailed video!

[@daydream2818]

@@Vaguh only count the holes that have wires in them not the empty ones correct?

@@daydream2818 Correct, the "empty" holes are where you will insert your tool to depin. There are only 5 rows of pins.

[@NerdGenius]

I have their true flex tune on the is38. I’m quite disappointed it only makes 12 more whp than the 93 tune with e70. The e85 is20 tune actually makes the same power as a is38 on pump. My 60-130 was low 11s on e70. Now I’ve been with IE for almost 3 years on my GTI. Had stage 2, is38, and now their true flex. IE is still very conservative but it works! So I Picked up a Cobb just to try other tunes. Eqt e30 is38 stage tune I ran a 10.5 with a pretty bad DA on the first run. I’m just seeing what else is available. I’ll still buy IE products because they are top notch but I’m moving from the tuning aspect being fully vested for years. Their development is just slow. Took me a year to go from v1 to v1.6 on is38.

[@deezyb858]

I'm with eqt right now, and waiting on the Trueflex for IE. I'm trying to figure out if i should just get the eqt e85 tune or wait for the IE trueflex. Would you say the eqt e30 tune was faster than the IE trueflex on e85?

[@NerdGenius]

@@deezyb858 yes it is faster. The tune on IE is tuned for safety in mind. So it will never net over 372whp that ie tuned it in safety for.

[@deezyb858]

@@NerdGenius is that 372whp stage 2 E85? If so, that is conservative.

[@NerdGenius]

@@deezyb858 e70 true flex is38 file. Reason being is that a is38 maxes out on e50 with a hpfp unless you have a really strong stock lpfp. So IE calibrated to run less boost as you add more ethanol to prevent your fuel pressure from dropping and causing you to run lean. Yes EQT runs more boost but remember if your lpfp is weak it will cause fuel rail pressure drops. Not all lpfp are created the same. I seen some drop fuel rail pressure at e40 on the is38.

[@MeltingRubberZ28]

@@NerdGenius I'm personally somewhat on the fence with IE basically because of how conservative it may be, however their IS38 numbers for 19+ cars are pretty decent. I'm hoping that their flex tune for 19+ IS38 setups also show that. I don't know who would be against replacing their LPFP if it meant making another ~30WHP.
