Waiting for Part-2

[@dinto_louis]

You had mentioned that (10:14) IAT is really high Where does the intake draw the air from in this series of engine..? from the engine bay..? or from the grill (outside air)..? Simple/1500₹ euro spec air channel guide made a significant difference in my polo in terms of IAT 1T0805971

[@HarmonixxTuning]

It's impossible for a Euro Spec Air Channel to reduce IATs drastically enough to see a difference. Specially on the 1.2/1.0TSI engines that have a tiny charge cooler. All the MQB engines draw air from the grill.

[@dinto_louis]

​@@HarmonixxTuning mine is a 1.2 TDI, not a TSI..difference is definitely felt..if it's not drop in IAT what could be it then..? There is no difference in lower speeds..as we climb higher in speed, there is that eagerness in picking up pace even further..there is no tapering off when compared to my friend's TDI Is the velocity of air being drawn different for euro spec & indian spec..? if it's so, would that make a difference esp as the car picks up speed..?

[@HarmonixxTuning]

To compare IATs, you will have to Datalog your car with and without the Euro Air Channel. In our experience of tuning VAGs for over 6yrs now, we've never seen an instance where Air Intake mods have aided in bettering IATs.

[@dinto_louis]

@@HarmonixxTuning no option to do so as I am not intending on tuning it Is it possible to data log while on the move..? or you can do it only when stationary..? In case you get a chance to test this please do, the difference between euro spec & Indian spec in these scenarios on IAT . stationary, while on the move@ say 100kmph . early morning runs (say 4/5am), drives @ noon . effect on TDI, TSI

[@HarmonixxTuning]

Datalogs are always taken when the car is moving, either on the road or on the Dyno. Also, take our word for it when we say a Euro Spec channel WILL NOT reduce IATs enough for you to FEEL a DIFFERENCE on these cars.

[@noshwhiakdhssdd]

Hey man! Would love to see you doing a video on the vw tiguan, it would be wild!! Keep up the good vids.

[@HarmonixxTuning]

Tiguan runs the same engine as the Kodiaq. So the results will pretty much be the same. We'll make one if we get a chance to work on a Tiguan in the future.

[@MrAdithramesh]

Great video. Please show us the difference in performance for both diesel and petrol cars with just aftermarket replacement air filters. Because you have got all the setup to measure and put a genuine report. Thanks.

[@HarmonixxTuning]

Air Filters don't make a lot of difference on cars under 300HP.

All the way from Malaysia! Man your videos are so informative! Love the clarity on the subject.. would love to get some guidance from you.. i have a 190ps Arteon.. looking to tune it sometime soon.. do you think its possible to push this engine above 300whp? How can this be achieved?

[@kshitijgupta1861]

Informative ❤

[@dipsLair]

Good video as usual , had to watch it couple of times to grasp all the information. I had couple of questions :: -> what is Lamda significance and we keep it "1" in lower revs ? -> Can you make a video and bust some myths on "claimed high HP gains" in NA engines ? -> Can you help educate folks on how to actually make any significant HP gains with NA engines.

[@HarmonixxTuning]

Lambda is basically how we quantify Air-Fuel-Ration (AFR). A good place to start would be the Wiki below to get a basic understanding. en.wikipedia.org/wiki/Air-fuel_ratio To bust the myths on NA engines we will need some NA cars and tuners willing to provide their tunes for FREE. Or customers with NA Tuned cars volunteering to Dyno their cars and allow us to flash their cars back to stock. Slim chances of either. Honest advice, just stop trying to mod an NA engine.

[@talamascaxsi]

Great video. What about the 220ps version sold outside india? Is it the same budack cycle engine ?

[@arbajrahman]

We need part 2 asap !

[@anan7s294]

Nicely explained video, but I have a few questions though- 1. How's the exhaust flow after the tuning- CO2, Nox, etc. 2. Is tuning engines legal, if yes in what states 3. I know the price of remap varries from model to model, but can we have a rough idea of it? stage 1/2/3/4 4. What's the max HP this 2.0 TSI can produce, i saw a video of AutotopNL he drove a 700hp RS3 engine swapped in a Superb n it was doing 300+ like a piece of cake, no stress whatsoever. 5. how much does the fuel efficiency increase in lower rpms after the remap? 6. Possible to add a supercharger instead of IS38, if not which IS38 do u recommend?

[@HarmonixxTuning]

On our Stage 1 Tunes all cars will pass Emission Tests. Price depends on your end goal, the platform and various other things. Our cheapest remaps start at 20k and can go upto 3-4L for a tune. An EA888 Gen3 can push around 600HP on our Dyno on a stock block. Upto 750HP on a built block. We've already built an Audi TT pushing out 600HP. RS3 engine is a 5 cylinder 2.5L engine and is probably the best tuner friendly engine made in the VAG line-up. FE depends on your driving style and driving conditions. Turbos are always more fun than a SC.

[@CyrusDastoor]

Superb channel, thank you. Ever tried comparing your tune vs the superchips UK tune? I ran their tune on my Ecosport 1.0

[@HarmonixxTuning]

As a tuning firm, comparing our work against our competitors publicly would be unethical unless the representatives from the other firm were also around while the testing is happening.

[@viktormitic822]

What milage can be expected form these gen3B engines? I have a 190hp czpb from Audi, first itteraton from 2017 (no opf, same dq381) it has 110.000miles and i plan to keep it until it explodes, oil is done every 5000 miles, the timing chain was replaced and both the thermostat and water pump were replaced under warranty. It does not burn oil at all.

[@pozytywniezakrecony151]

Sir is there a part 2 or it didnt work? I am getting 2018 DGUA US version of Tiguan and wonder if I will get just few more HP or much more :/

[@adityasundar324]

What is the possibility of remapping the Korean 1.5 TGDIs? (Not sure if India gets the 1.5 G4LH and G4FS) and what is the maximum torque the D7UF1/D7F34 Dry Clutch DCT handle (without reliable issues) ? Will you be coming out with a remap for the above engine + gearbox combination? Thanks

[@HarmonixxTuning]

We've got some nice tunes for the Hyundai/Kia 1.0TGDi and 1.4TGDi engines. No TCU tunes for these yet. We've not yet started work on the newer 1.5TGDis yet.

[@ameenshageer]

Code6 needs to learn from you guys

[@HarmonixxTuning]

If they did, Harmonixx Tuning wouldn't have come to be. Our owner was the 2nd founding partner at Code 6 many moons ago & Harmonixx Tuning was started because they wouldn't agree to let him do what we are doing right now at Harmonixx :)

[@vipreshschannel9859]

when is the next part for this coming out?

[@yashgite4527]

Hey Rahul, are the new EA888 Gen 4 engines better at tune-ability than these Gen 3b engines? Do the EA888 Gen 4 engines have a lower compression ratio similar to the engines found in the Vrs230/ Audi 45 Tsi etc. ?

[@HarmonixxTuning]

The Gen4 engines sold in these newer cars in India, just seem to be updated Gen3B engines with a few updated parts from the Gen4s sold abroad. This still run very high compression and will react similarly to the Gen3B engines. We don't see these making more power than the Gen3Bs around.

[@kalyaan123]

Do you have a stage 1/ stage 1+ tune for the 1.3 mjd with the variable geometry turbocharger in the ciaz by any chance? And how much hp and tq gain can we expect after flashing it on a stock engine?

[@HarmonixxTuning]

We have a pretty nice tune for the Ciaz.

[@superfitcs4005]

How robust is DQ381 compared to the previous and yes how far can one push through this engine with reasonable reliability peace of mind?

[@HarmonixxTuning]

The DQ381 is one of the most robust DSG gearboxes built by VW. And can take a lot of abuse and nearly 650Nm Torque without complaining. As for how much can this engine be pushed to? Wait for Part II to find out.

[@flyingbird5924]

How much we can push an 1.3 MJD?

[@HarmonixxTuning]

+15HP +30Nm

[@flyingbird5924]

@@HarmonixxTuningIs it possible to swap hybrid turbo with 1.3 MJD?

[@HarmonixxTuning]

No good options out there for these engines. We recommend a Stage 1 Tune.

[@arunojha10]

What could be the best turbo swap for gen3b block

[@HarmonixxTuning]

The most popular turbo upgrades are the IS38 or the Garrett Powermax Stage 1 Turbos for these Gen3B engines. However, once you decide to go Stage 3 you'll need to ensure you fill up really good fuel as these engines have very high compression & will become extremely sensitive to fuel quality as you start pushing them.

[@Iti755r-xz2dk]

As I do lot of long drives and fuel quality is 95 at most places , do you think IS 20 turbo will be better or even I. Can mildly tune IS20 turbo to get around 270hp , I have stage 1 , just need little bit more power than stage 2 while keeping it reliable

[@HarmonixxTuning]

Honestly, we've to done a Stage 3 on a GEN3B yet. We personally think the risks are too high given our suspect fuel quality (even on XP95 the fuel quality seems to vary wildly between bunks/cities).

[@prateeksaxena1812]

[@blazbohinc4964]

I'm getting the new Kodiaq with 2.0 TSI - 204hp variant once it becomes available in august. I'll get it tuned on 100RON fuel and hopefully we can reach 230-240hp without pushing the turbo too much. Fuel is everything, my tuner won't even take the car in on 95RON, says it's a waste of his time to try and tune the car on shit fuel. And I agree.

[@HarmonixxTuning]

Ya, unfortunately 100 RON is not widely available in India and costs a lot more than 95 RON. Hence we are forced to develop 95 RON maps for most cars out here.

[@rahulr688]

what power figures can we expect if get a vrs 245 oem turbo for this car with supporting mods ( if needed )

[@HarmonixxTuning]

An IS20 on this car should net closer to 270-280HP in our opinion. But the wiser option would be to swap to an IS38 instead of an IS20. But then again, the high compression on these engines, makes them tricky to tune with a bigger turbo, specially on our fuel.

[@MayankShekhar]

I have a Kodiaq from late 2023 and everything you mentioned about how to identify a Gen 3B engine is not present. Matches more with 245 engine. Do you know if newer versions have the Evo4 engine?

[@HarmonixxTuning]

The latest batch of Gen3B engines seem to have the engine code DNNA which runs a high compression ratio of 12.2:1 and does run some common plumbing parts from the Evo4 engines. This could be VW trying to discontinue older SKUs as they slowly phase out the Gen3 engines to Evo4. The same has been reported on the new Q3 as well. But we're certain these are the facelifted Gen3B engines.

[@MayankShekhar]

@@HarmonixxTuning As per the official Skoda storyboard, Kodiaqs with Euro 6d emission standards have the latest generation of Evo engines.

[@aaronlangevin322]

What tuning software are you using to reflash the ECU?

[@HarmonixxTuning]

We use a tool called CMD and flash custom software using it.

[@Iti755r-xz2dk]

Hi Rahul, I have allspace stage 1 currently , I need more power , I was thinking of a engine swap with 1.8 stage 3 IS20 280hp but then it will cost me around 5 lakhs and I won't get good price for my current engine So I was thinking of pushing my current engine to 250-260hp with mildly tuned IS20 turbo. If it can last 15-20k km , it is worth it and then may be I will rebuilt it or swap it with 1.8 whichever is cheaper. Do you think it can produce 260 hp safely for 15-20k km?

[@HarmonixxTuning]

Hi Pawan, honestly doing an IS20 build wouldn't be that difficult for our team. Drop us a text on Insta and let's discuss.

[@blacksparrow1818]

Have you tuned an Octavia MK4, as I haven’t seen one personally a EA888 gen3B 2.0 TSI Octavia being tuned?

[@dieselhead999]

How capable is the dq381?

[@HarmonixxTuning]

We can extract a ton of torque & power out of the DQ381s.

[@sarathchandran4725]

400 to 420 safe side

[@HarmonixxTuning]

More like 550-600HP and 650Nm Torque.

[@andrzej8074]

What about engines, gen4b, for example dmsa 40tfsi 204km. Will it be possible to modify them?

[@HarmonixxTuning]

DMSA engines look like GEN3B with some parts off the Evo4. Easiest way to identify them is to see the Compression Ratio. If it's not 9.3/9.6:1 and is closer to 11.6-12.2:1 you can be rest assured that those are the High Compression Budak Cycle engines.

[@andrzej8074]
