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!

Airflow Increase

When adding boost and timing naturally the engine moves more air. We increase air limits, expect air volume for the manifold charge.


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. 

Customer Reviews

Based on 12 reviews

I’ve had my VN tuned by Dan for over 100,000 km’s now. Car runs great and has a lot more power then stock, like way more torque at mid range and keeps pulling as long as my stock turbo can. I get comments and thumbs up multiple times a week with the more aggressive pops, being able to go to sport or comfort and not have them is also nice. Can’t say enough about n75 and their customer service and response time. Every mod I’ve purchased from them has worked great and if I had any issues Dan made sure I was satisfied with the outcome.

Honest review.

I had recently gotten a veloster N 2021 (dct) it is now FBO, everything it recommended I got, anyways, I was worried that the tune was not going to do much OR I had really HIGH expectations, I got the spare ecu tune stage 2 with pops and 7k rpm shift, which in my opinion is more than enough for a fun daily. HOWEVER, it does wake the car up; it almost feels like the price to power ratio isnt there, low rpm it feels like a normal car before the tune, the only real time you can feel any difference is if you go from 3-7krpm 40mph to 120mph. that being said make sure to upgrade your tires to super sports as you will almost never catch any traction, if you plan on runnin on back roads, or torn highways. my recommendation when running a tune higher than stage1 is to fully finish upgrading the other aspects of the car, downpipe and intercooler along with all the other items they recommend, Daniel was fantastic with his QUICK responses and great service and dont get me wrong I love the tune I got and wouldn't go any other way. I will say this though, the crackle and pops ARE worth it.

Power in the lower RPM is held back to protect the turbocharger. No sense in spiking to 24psi for a split second at 2.5k RPM. it's just going to damage the turbo and engine over time.

Kyle Logue

Don’t feel much change In performance but definitely makes more pops

2020 VN tune.

Dan was a pleasure to work with. It Can be a difficult thing figuring out what company you're going to buy parts from and who's going to do your tune. Dan's response time was very fast, he was very patient with me ,and my million questions. His knowledge of both product and tune was impressive. He gets 5 stars in response time and vehicle knowledge. I was worried working with a Canadian company, and living in Hawaii it would take a very long time to get the ECU. From time of purchase, to receiving the product took less than 10 day, 5 stars and product delivery. (The package came with bunch of stickers keychains and even some treats to snack on as I installed it. 😁). Finally the fun part the tune itself. The car keeps 100% of its stock features idles fine, everything works the same as stock. You would never know it was tuned when you're just cruising around town. However put it in N mode, stomp on it and it's a whole nother animal. The car's boost comes on faster smoother, the car accelerates in all gears clear up to 7000 RPMs. The cars torque comes on smooth and makes it easy to drive, there's power and torque any gear at any RPM. It's hard to truly explain how impressive the car is now. The tune itself 5 stars. Overall experience 5 stars, thanks Dan keep up the good work, look forward to doing future business with you. 🤙🏼

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
