 Hyundai made changes to the ECU in 2024, 2024 owners cannot use 2023 ECU's. EK1 devices do not support the 2024 MY as of yet, however it is in development. Our tuning services are one of the only ways to tune your 2024 Elantra N. (Tuning / mapping remains the same, the bootloader (the area of the ECU that allows flashing, was changed in 2024 by Hyundai to deter tuning, and a flash counter was added)

 

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.   

Fan Control Adjustment

The coolant fan is adjusted to help keep the engine cool on street and track, where the fan out only come on at 50%, we set it to 100%, help keeping the car cool.

DCT ECU Interface Removal

During different driver shifter selection positions, the DCT has a reduction in power output. This is removed on Stage 2 plus tuning. 

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.

Max WOT

(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 not guaranteed every time you rev the car, but will shoot flames when rev hanging) 

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?

 

ECU needs to be sent into N75 Motorsports in Mississauga, Ontario, Canada

We ship your ECU with full insurance coverage, and overnight UPS/DHL Shipping to reduce downtime.

 

Stock WHP is around 240-270whp. (Depending on dyno, fuel, conditions and if octane learned) We made 242whp stock on a Elantra N 6SPD without octane learning. 

 

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)

295whp/310ftlbs 

 

 

 

 

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)

305whp/330wtq

 

 

 

 

Stage 3 Required Mods (High boost High Torque)

Heat Range 9 Spark Plugs

Intake

HPFP Upgrade

FMIC Upgrade

Downpipe and catless or high flow exhaust

315whp/350ftlbs

 All maps have been dyno tested by our dealers overseas. 

 

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.

 

If you are not happy with our tune for the N, send us your ECU back, we will flash it back to stock, refund you and cover shipping fee's.

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.

Pretty Flawless

1st off, the tune itself amazing. 0 issues, from the start., Nothing but ease, Daniel was there to answer my emails, right away, and Rick from the shipping dept even answered a phonecall and gave me a detailed run through. That being said there could be some instructions….it would be super beneficial.
I was anticipating some instructions after I made the purchase but there was nothing, so I went through the contact us and started emailing Daniel/Rick/shipping etc, being like “Uh, where am I sending this? Am I putting it in a box? Are you sending me a label? Etc” There was just absolutely 0 direction until I reached out to track it all down. Some people might not do that, so I think there could be just a quick summary blurb on the page explaining the process.

Hey Cody,

We're so happy to hear that you're loving the tune for your Hyundai Elantra N. We always strive to provide a flawless experience for our customers, so it's great to know that you had no issues with the tune from the start.

We apologize for the lack of instructions after your purchase. We usually send an email with shipping directions, but it seems like you didn't receive it. I will personally speak with our shipping team to make sure this doesn't happen again in the future.

We're glad that you reached out to us and that Rick was able to help you out with the process. Thank you for your feedback, we will definitely take it into consideration and add a summary blurb on the page to explain the process better.

Thank you for choosing our services and we hope you continue to enjoy your Hyundai Elantra N with the new ECU calibration file. If you have any further questions or concerns, please don't hesitate to reach out to us.

Best, Team N75 Motorsports

N75 ON TOP!!!

After putting my N75 stage 2 tuned ecu in my car I was absolutely mind blown. Coming from having a JB4 tune on my Elantra N, this N75 stage 2 tune had my jaw on the floor. My car now feels completely different, insanely louder and wayyyyy faster. Don’t bother wasting your money on a JB4 or a 200$ Facebook marketplace tune, N75 is the way to go.

With you the whole way

Been running stage 2 off that bat and had some problems here and their regarding fueling. Daniel has been with me the whole way, answering questions and adjusting tunes while adding revisions whenever asked. He answers every question I ask even when they don’t relate to tuning.

Highly highly recommend N75!

Glad the injectors fixed it!
