We supply new ECU.

Tune your Veloster N without any downtime! 


N75 Motorsports ECU's DO NOT disable Bluelink unlike other tuners, Bluelink on our ECU unlike other tuners works like OEM due to our extensive research and development. We are able to do this without touching your OEM ECU with only your VIN number and transmission type! If you want not only a ECU tune, but a proper product that doesn't compromise OEM functions like Bluelink? N75 Motorsports is your only option!

Tune Features

Engine Fuel Delivery

The N series engine's has fuel delivery not set for high boost, if tuners do not account for this the ECU will pull power and cut fuel under high demands. We optimize these maps for the HPFP and fuel delivery to engine to prevent this cut from happening.

N Mode pop enhancement. (Optional)

We change the pop sound through the ECU. The OEM Hyundai pop sound becomes far more aggressive. Only in N mode like OEM. (Recommend high flow downpipe catted or catless)

AFR Adjustment

(Hyundai's are known to run very rich from factory our tune corrects this and your N will not only make more power but get better fuel economy doing it!)

Torque Management Increase

(Torque maps for the engine are changed to make more power without causing issues, you cannot just lift boost)

Increased ignition timing

(Area's of the N's ignition timing can be well optimized by us, we do this and the result is a smoother powerband)

7200 RPM Shift on DCT and 6SPD

We offer 7K Shift on DCT and 6SPD Cars. Yes you read correctly DCT N Owners can now enjoy 7K Shift as well! This opens up the game for the Elantra N, Kona N, and Veloster N with EN Turbocharger swaps as 7000 - 7200 RPM is needed as these cars have a bigger turbo which make boost in higher RPM range.   

Turbocharger management optimized

(Wastegate duty cycle, pressure application and turbocharger limits are changed, boost is increased as well)

Optimized VVT

(VVT can be changed slightly to make more power)

Disable primary O2 sensor monitoring

Monitoring systems for the primary O2 are changed so they never trigger a fault code, however no fault codes are deleted.


(During WOT the ECU switches to certain area's of maps in the ECU's we optimize these maps all in relation so the car makes a proper powerband)

Overboost Correction

On the N Series Cars we typically see overboost around 18-20PSI. For tuning we lift this to around 25PSI. More aggressive maps (Stage3+) we remove overboost completely as we boost some of these engines on Hybrids very to very high boost levels, like our stuffed turbo Elantra tune which runs upwards of 28PSI.

Warmup Protection

Increased warm up protection (Full power and boost only comes on when engine oil is up to temp)

Pop Flames

Flames can be tuned in as well, car needs to be catless. (Flames are guaranteed every time you rev the car) These are aggressive tunes, hard on the motor and turbo.

Engine Temp. Managment.

Stage 2 and 3 tunes require an increase in allowed temperature for the exhaust model and intake model. These maps are lifted so the car maintains power towards redline. This is an OEM safety which ALL tuners need to increase for the car to power, we do not take responsibility nor do any other tuners for damage caused by lifted the temp limits (IE You do not have the supporting mods and motor runs extremely hot)

Octane Learning Disable

We disable octane learning and it never bugs your again, or we leave it on the tune.

Assisted Launch Control

During Launch ready and first and second gear we add more boost when LC is used. Maps during the LC Process and during first few gears is increased though tuning.

Increased DCT clutch pressure

Through various torque and TCU related maps in the ECU we can request the ECU to request the TCU to increase Clutch clamping load on DCT Vehicles. 

2 Step Style anti-lag (DCT ONLY)

Aggressive pops and flames during LC spin the turbo upwards of 17-18PSI! Check out our latest IG Posts and reels for samples of this tune.

True Valet Mode

More of an EK1 option, we can make a map where the car doesn't exceed 40MPH or 10PSI boost level, ensuring Valet doesn't enjoy your car!

Developed by N75 Motorsports in Canada,  our newest N Series cars ECU Calibrations are the most advanced Calibrations we have produced.  Rest assured your tune satisfaction or your money back! Now ask yourself,  how many others will do this?


WHP Numbers are for Velsoter N

Stock WHP is around 225-240whp.

Stage 1 Tune Required Mods (Made for a car with no mods, this tune corrects some issues with the OEM tune from Hyundai like AFR and nets better fuel eco)

HKS M45XL Spark Plugs (Recommend, not required)

HPFP Upgrade (Recommend with an OEM Tune as the HPFP is a weak point on this vehicle)






Stage 2 Tune Required Mods (Made to last the life of the car)

HKS M45XL Spark Plugs

HPFP Upgrade (Recommend to avoid issues)

Air intake system (Any, we use AFE)






Stage 3 Required Mods (High boost High Torque)

HKS M45XL Spark Plugs


HPFP Upgrade

FMIC Upgrade

WMI Required 

Downpipe and catless or high flow exhaust


 All maps have been dyno tested by our dealers overseas. However we under list power ratings due to unknown fuel conditions as we tune cars all around the world. 


Our tunes are fully customizable, we also use tools which allow OBD flash, we offer free flash back to stock for any of our local customers, as flashing with this tool is a few minute job.



Using WinOLS5 and our network of tuners around the world, we have been able to to come up with a working mappack for Hyundai N Series Vehicles, this mappack is so advanced that only a few tuners can do some of the things we can, 7200RPM Shift, 29PSI tunes, Pop Flames and more. All of this is only possible with the development we have done with our own R&D car and our test cars overseas. Our tuning is so advanced our older mappack is used by companies like AlienTech, the software other tuners use to make a tune.

Recently we have been reading a lot recently of people making a big deal of making big power on the OEM HPFP. This is beyond stupid, allow us to explain, is the OEM pump capable with tuning? Yes, However so are heat range 8 spark plugs to make 400whp (and people have done it) But again, its rolling the dice. What is the point? We understand the HPFP is not cheap however your motor is not cheap either, we can tune the OEM pump however we suggest replacement to avoid issues. No different from spark plugs.

Just got my hands on the spare stage 2 ECU and wow. Well worth it power delivery is night and day with a big feel it in your but power increase. Also seeing a pretty good bump in fuel mileage I have had the car for about 25k and my average mpg was 23.4. I'm on my second tank and I've seen 28-29 mpg so far ! . Absolutely amazing tune really makes the car feel like how it should from the factory. 2020 N pp

I had been lucky enough to grab a Tuned ECU and recently had a chance to really take some time to put it through a thorough pacing.

The tune is set to stage 2 and has a -very- aggressive pop tune at the time of this review.

Now to be fair, I had the original tune. It was aggressive but it was manageable during N mode, but it lacked refinement. It was a broad stroke and it was fun!!

At stage 2 AND an aggressive pop during off acceleration the pops last about 3 seconds, which doesn't seem like much but I was used to .5 or 1 second of pops and gurgle in N.


I broke necks driving home. Having that said, sport mode is competitive underfoot and has even a more refined and less gurgle/rumble than before. I sort of miss them but hope to work with Daniel Cisalowicz on making this aggressive nature a Custom selection and N Mode being more subtle with Sport as a gurgle and rumble whilst on a drive.

As it stands I am still fully excited for the change and hope the AutoX/ track days are not overly exuberant.

In this aggressive state I am more comfortable using Sport, feel that even more refinement is in the works and will happily keep N75 a part of my journey.

5/5 for overall experience

5/5 for power and control

4.5/5 for the pops, but again if we can make this a mode selection, it would be great for shows, and raw power

5/5 for customer service, customer satisfaction and support.

I have full confidence Daniel and N75 are making sure as a Stock Turbo VN user, I am enjoying what is capable without danger.

Happy Cruising!

Stage 1 Spare ECU w/ moderate burbles

The tune is amazing my Veloster N DCT has woken up with more power than before about a month of driving it’s very smooth and refined. I can’t stop driving it in N Mode the smile on my face everytime I accelerate I highly recommend n75 my YouTube channel: Chris Mac will document my experience.

Ecu tune

I ordered a spare ecu with stage 3, and am very happy with it

Ecu tune

Couldn't be happier with the stage 2 pop tune? It's advertised and there's definitely a huge difference.
