Tune your car without any downtime!

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



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)

7000 RPM Shift on DCT

We offer 7K Shift on DCT 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 as shown in our dyno testing.  

Turbocharger management optimized

(Wastegate duty cycle, pressure application and turbocharger limits are changed, boost is increased as well) opening limits of the wastegate is also changed to help spin up the turbo. 

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. (DTC for O2 Faults are not removed unless asked for)


(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 hang the car)

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 due to incorrect fuel, plugs, charge pipe leak, not using recommended engine oil, poor maintenance, incorrect or not recommended WMI fluid, a preexisting mechanical issue which only becomes far worse on a tune.)

Octane Learning Disable

We disable octane learning and it never bugs your again, or we leave it on the tune. (By default, all ECU's have OL disabled)

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. Our tunes can make up of 13psi during launching! (While standing still in Launch mode!)

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. This is extremely important for DCT owners, piggybacks on the new N cars due to the larger turbo is known to spin the clutch,  this is for a few reasons. Mainly the ECU is simply not requesting that level of clamping force from the TCU due to OEM power levels in the ECU. Secondly we have a few "tricks" which we have logged with Hyundai dealership scan tools (the best way to log a KDM) and have seen in our logs clamping force on the clutch increase significantly with our "tricks" applied to the ECU. These are not TCU directly related maps, however,  when we ask these maps for more Torque, the ECU requests more power from the TCU. 

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, expected 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?


 Stage 0

Octane learning disable for boost control and ignition timing. Very slight AFR adjustment.

Stock WHP is around 250-270whp.

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)


A custom Stage 2 tune (fine tuned off logs) powers an Elantra N DCT to 12.00 @117mph, this is highly possibly the fastest DCT OEM turbo car in the world. 




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.

We now have full damos for this ECU, this means no Grey area's,  no guessing, no more issues with tunes as everything is now crystal clear to us. We are proudly the only tuner in Canada with full damos support and one of a handful of tuners around the world whom has access to this file. (A damos file is a file from Hyundai, it tell us every map on the entire ECU, to the extent we can change the vehicle year on the ECU, this file makes tuning much easier for us, and gives you a better more refined product.  This is why our N Series tuning really took off in 2023, due to the added definition support, we no longer need to search and guess for maps.

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.

2023 EN 6 spd manual spare ECU Stage 2 tune

Definitely worth it so far. Runs amazing its feels like 100whp overstock. Flame Pops are super loud. Puts a big grin on my every time i drive it. 😁😎

Sean Starnes
Definitely makes a difference

I added this unit right after it arrived and couldn't be happier. Makes the car more responsive. Would recommend to anyone looking to add some hp and pops

Easy plug and play.

I ordered the stage two tune on a spare ECU. I did all the supporting mods and popped the ECU in. My car didn't start at first. I messaged Daniel, and he said it may be due to my battery being weak. I used a battery jumper, and in about 5 seconds, it turned over with the new ECU. I've had the tune for about a month now, and it's been great. My car's internal HP tracker says 334 hp. I'm not sure whether it's true or not since I've never had my car on a dyno, but it's exactly as advertised and seems to match what N75's graphs show. The power curve is more linear than stock and feels perfect.

A whole new world

Installed my stage 1 on a spare last week. Daniel killed it again. The car is a new beast and the powerband is so smooth. I'm in love all over again. Best customer service out there and the best in the tuning scene for our cars IMO. I wouldn't trust anyone else with my car. Can't recommend enough.

Smiles & joy

Tired of octane learning? Not so Great fuel economy? Tired of getting bullied by the competition?
An N75 spare ecu tune will fix all that for you 😁.
