Tune your car without any downtime!

Our ECU's work on all models anywhere in the World!


Tune Features

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. 

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) 

 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.

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.




Developed by N75 Motorsports in Canada,  our newest N Series cars ECU Calibrations are the most advanced Calibrations we have produced. The work we have done on the N series vehicles is something we are proud of,  rest assured your tune satisfaction or your money back! Now ask yourself,  how many others will do this?



WHP Numbers are for Elantra N

Stock WHP is around 250-275whp.

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)

Heat Range 9 Spark Plugs

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)

Heat Range 9 Spark Plugs

HPFP Upgrade (Recommend to avoid issues)

Air intake system (Any, we use AFE)






Stage 3 Required Mods (High boost High Torque)

Heat Range 9 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.

Bought stage 2 dct ecu. Did one run so far and it holds at least 20psi. Car is almost perfect. Shoulda came this way from the factory. Now for some stiffer springs and maybe new wheels. Eco mode still gets bout 30mpg too. Thank yall much ☺️

Liam S
Stage 2 ECU Tune EN 6mt

Daniel truly did some fantastic work here. Not only did he answer every question I had in detail, but the tune is fantastic. Not only have I seen peaks of 22psi when looking at the dual gauges, but the car runs better for daily driving. Better fuel economy, and the sport+ exhaust valve opens up after 2k so drone is reduced when cruising. The extra power is definitely noticed on the highway, it’s a night and day difference. Would highly recommend N75 tunes to anyone looking to upgrade their Hyundai.

Unleashes what Hyundai engineers left on the table... Stage2

The overall drive has been refined. From the brash tone of the exhaust at low speed to the jerky nature of the DCT. It's like the experience finally graduated from boy racer to the high end club. Much smoother idle... everything is amazing! Maximizes what the chassis dynamics have to offer. Full effect happens under full throttle... ALL THE TIME. With 93 octane I regularly see 20-22 PSI and depending on conditions I have seen a max of 24 PSI. In short... THE THING MOVES, way more than it did before. Daniel and his team at N75 Motorsports underpromised and definitely over delivered here. I'll be back for more...

Stage 2 ECU tune

Wow first time I buy a tune that is smoother than stock one and in same time being way more powerful !! Daniel answered all my question and he is very professional! Can't complain on anything !

Jordan N
Stage 2 tune: More power, no octane learning!

Just took the car on a 1200 mile trip immediately after tuning...(6MT) I really like how the car is much more responsive in higher RPMS, so there is no need downshift to do a quick maneuver on the interstate. Smooth power delivery across the board. Bangs and pops are even louder.
It's worth it just to get rid of the octane learning!

Thanks for your feedback Jordan! Glad we could solve the octane learning issue for you!
