Time for the FINAL Stage 1 - Low Torque Dyno Comparison on my 2023 VW GTI! Now that I've tested both 91 & 93 octane tunes, it was time to step it up to E85. I was expecting to make more horsepower on ethanol, but not THIS much more! Some incredible results were achieved by running a Stage 1 - Low Torque tune on all stock hardware in my MK8 GTI. Next up... HARDWARE MODS!!!

Good one! No surprise on Unitronic...they like the timing advance and can get it smoothly running E.

They sure did

[@devinmathis4548]

I love your videos! If the cars will make that kinda torque with e85, I honestly think you can run the 87/93 stage 1 tunes (without low torque files). I'm probably not the only person that would also love to see those results. Different tuners can use different factors to limit torque, so I'd be really interested to see how they all stack up against each other with the full-on tunes. If not I understand. Just a suggestion, but I really do love your videos and hope to see many more with this platform. I have a 2024 380 se gti, and I follow you weekly and will be deciding my tuner off of your videos.

[@VancityAudi]

Sorry dude! I won't be dropping back in power for any reason. I'll only be making more power from here on out.

[@skyhookpro]

Nice all of this without a huge modification..my guess is once you finish modify you hardware my guess your car should touch 680..let see the future videos....great work Adam!!

[@VancityAudi]

Hahahaha. I'm sure I'll be able to add a bunch more horsepower to this little beehotch with a few more hardware modifications!

Another great video. What is the maintenance schedule on your car with all this dyno runs? oil change interval , spark plug change interval , spark plug gap . Have you done a DSG service?

[@VancityAudi]

Lol, as you can see on the dash, the car only has 15,000km on it. 3 oil changes, that's it. Roughly 7-8k between

[@Michael-rp5tc]

I really like the performance of Unitronic’s flex tune on my TTRS. I certainly have my criticisms of them but they’re nothing if not responsive and helpful.

[@VancityAudi]

[@JaredDutton-xw4gt]

Unitronic is usually the “conservative” one 😅 amazing! They did a great job.

[@VancityAudi]

I've never understood where this description came from for Unitronic tunes. I've been using their software since 2016 and have NEVER seen it as conservative.

[@siddharthyadav213]

@@VancityAudiI think they’ve gotten the “conservative” reputation because they use more timing and less boost, and so on butt dyno they feel like they have less kick. At least that’s what I’ve seen on previous gens

[@VancityAudi]

​@siddharthyadav213 I see. I've always seen them as being one of the quickest & fastest in the 1/4 mile, so I've never considered them conservative.

[@Reptil33]

​@@VancityAudithat was the old conservative unitronic. If you had worked with them in early 2000s and up to mk7-mk7.5 GTI and golf R platform it'd be more clear. Mid boost and higher timing was their thing while keeping real good drivability. The rest of the tuner companies cranked out boost, high timing and throttle sensitivity. It wasn't until daza motor came around that they started changing toward being more aggressive, locking in that platform, now mk8 and rest of the platforms (this is all more recent). It's worked out really well for them regardless.

[@rastaph]

For the drag strip times are you going to test each tune at the strip or are you going to pick 1 tune and run with it?

[@VancityAudi]

I'm undecided at this point. Seeing as my RS3 should be track ready this year, I'll be putting that as the priority on the drag strip.

[@JordieG8]

Ethanol is fantastic at compensating for intercooling deficits, especially at higher concentrations. Which is why it’s not super surprising to see such huge gains over 93 on stock hardware. On a side note, some of those torque curves are gross, while others are quite nice. I may have missed it, but were you noticing repeatable dips between the 3 runs on those companies calibration that has them? Cheers

[@VancityAudi]

The adding cooling benefits of ethanol didnt benefit me like you are stating in this comparison. My IAT's were really low already due to the weather conditions I tested in. If I were to have tested in the heat where the OEM intercooler was being stressed, then I'd agree with you. As for the second part of your comment, I'm not sure what you're asking.

[@JordieG8]

@@VancityAudi where is the IAT located? And what was the delta between AAT and IAT? On the calibrations that had the huge torque dips, was it repeatable from run to run (of the 3 that you did on each).

[@VancityAudi]

​@JordieG8 you can always tell who actually watches the videos and who just scrolls through to the results by the questions they ask, lol. On every single company's dyno pulls I share the maximum IAT reached. No, the torque did not vary all over the place between the 3 runs. The graph was extremely consistent from run to run. As I mentioned and shared in the video, the environmental conditions I tested in were incredibly good.

[@JordieG8]

@@VancityAudi I watched, I just wanted to confirm you thought a 20+ degree delta was acceptable intercooling. You are rather arrogant hey?

[@VancityAudi]

@@JordieG8And you're a know it all YT commenter hey? None of these cars saw any timing corrections due to the IAT's. I know that an intercooler will benefit each of these tunes in terms of making consistent power delivery. If there was an intercooler installed, we wouldn't be anywhere near that delta. In terms of what I showed on the dyno though, the peak IAT's did not cause any loss of power which was what I was showing in this video.

[@sameftek9799]

did you need a hardware mod for e85? or the Tune does the calculation built in ?

I go through every single detail regarding the hardware in the video

[@leechavarie4675]

How would they work on Co-op E63 ?

[@VancityAudi]

As I mentioned in the video, all of these tunes work using E60 - E80, but most tuners prefer E70ish.

[@skywalk3x]

I just switched back to E85 on my TTRS. It’s such a dramatic difference than stage 2 93. I got a question when I switched there two different times that say “use at your own risk” I’ve read for drag racing prepped track and such. I have a deserted road that’s about a 3/4 mile all to myself. Would that tune be good for there? I’ve read in forums that people use the tune with no problems just wondering if you used it. Its Unitronic. Thanks Vancity!!

[@VancityAudi]

I'd need to know specifically which one you're talking about. There are a few labeled "USE AT YOUR OWN RISK"

[@skywalk3x]

@@VancityAudi ok it’s the one with 10 psi. There’s also a 12 psi but I’m on the 10

[@VancityAudi]

​@skywalk3x ohhhh, those. Basically that ramps up your boost on launch. Too much boost on an unprepped surface will more than likely cause excessive wheelspin. The other factor would be launching with more boost on launch is more likely to break something.

[@skywalk3x]

@@VancityAudi I tell you Vancity you’re so generous with your time to answer some questions. You’ve answered me now a few times even when I wasn’t directly asking you.

The theme so far is unitronic sucks at low torque tunes and wants manual cars to destroy clutches.

[@VancityAudi]

As I discussed in Part 3 of my Tuner Battle Series, Unitronic offers both a GBX file and a Low Torque file that works with a locked TCU. When I asked what files they'd like me to showcase, they wanted to see the GBX in action. If you want a lower torque tune, that is available on their server.

[@janakranchod]
