Fits: Hyundai Elantra N, 6-speed manual and DCT, including the changed 2024 ECU.
What this is
An N75 Motorsports calibration written to your own Elantra N ECU, in-house in Mississauga, Ontario, Canada. Send us your ECU or bring it in person.
Hyundai changed the 2024 ECU's bootloader (the flashing area) to deter tuning and added a flash counter. Mapping is the same as earlier years, but a 2023 ECU cannot be used on a 2024 car.
Stage 3 — 357 whp on our Elantra N 6-speed test car (Dynojet, STD correction).
Stages
Stock output is around 240–270 whp depending on dyno, fuel, conditions and whether octane has learned. We made 242 whp stock on an Elantra N 6-speed without octane learning. All maps are dyno tested by our dealers overseas.
| Stage | Power | Required mods |
|---|---|---|
| Stage 1 | 295 whp / 310 ft-lbs | Intake; heat range 9 spark plugs. Nothing else. |
| Stage 2 | 305 whp / 330 wtq | Heat range 9 spark plugs; HPFP upgrade recommended; any air intake (we use AFE). |
| Stage 3 | 315 whp / 350 ft-lbs | Heat range 9 spark plugs; intake; HPFP upgrade; FMIC upgrade; WMI or E30 blend with upgraded injectors; downpipe and catless or high-flow exhaust. |
Stage 1 corrects OEM tune issues such as AFR for better fuel economy. Stage 2 is made to last the life of the car. Stage 3 is high boost, high torque.
Options explained
- 7000/7200 RPM shift (any stage): shift point raised to 7000 RPM on DCT cars and 7200 RPM on 6-speed cars. Useful because the EN turbo makes boost higher in the rev range.
- N Mode pop map: pop sound changed through the ECU, far more aggressive than OEM, N Mode only like OEM. A high-flow catted or catless downpipe is recommended.
- Flame tune: pop flames tuned in; the car must be catless. Flames fire on rev hang, not on every rev.
- Anti-lag (DCT only): 2-step style anti-lag with aggressive pops and flames during launch control, spinning the turbo to 17–18 PSI on the line. Samples on our Instagram.
Pop map, flame tune and anti-lag share one dropdown, so you pick one per order.
How it works after you order
- Order with your stage and options.
- Send your ECU to N75 Motorsports in Mississauga, Ontario, Canada, or bring it to us in person.
- We write your calibration to your ECU and ship it back with full insurance coverage and overnight UPS/DHL shipping to reduce downtime.
Calibration features
Developed in Canada on our own R&D car and test cars overseas with WinOLS 5 and a worldwide tuner network. Click the badge to verify our WinOLS licence with EVC.
- Fuel delivery: N-series fuel delivery is not set for high boost, so the ECU pulls power and cuts fuel under high demand; HPFP and fuel delivery maps are optimized to prevent the cut.
- AFR: the factory calibration runs very rich; corrected for more power and better fuel economy.
- Torque, ignition, airflow and VVT: torque maps changed to make more power (you cannot just lift boost); timing optimized for a smoother powerband; air limits and expected manifold charge volume raised; VVT changed slightly; WOT map areas optimized in relation to each other.
- Turbo management: wastegate duty cycle, pressure application and turbo limits changed; boost increased.
- Overboost: stock typically trips around 18–20 PSI; lifted to around 25 PSI, removed completely on Stage 3 and up.
- Warmup protection: full power and boost only once engine oil is up to temperature.
- Engine temperature management (Stage 2 and 3): allowed exhaust and intake model temperatures raised so the car holds power toward redline.
- Fan control: coolant fan on at 100% instead of 50%.
- Fault prevention: primary O2 monitoring never triggers a fault code; no codes deleted.
- Octane learning: disabled or left on, your choice.
- Assisted launch control: more boost during launch-ready and in first and second gear when LC is used.
DCT only
- Interface removal (Stage 2 and up): the DCT's power reduction in certain shifter positions is removed.
- Increased clutch pressure: the ECU requests more clutch clamping load from the TCU via torque and TCU-related maps.
- 2-step style anti-lag: optional, see Options explained above.
Before you order
- Run the required mods for your stage. We can tune on the OEM HPFP, but it is a weak point on this car and rolling the dice, so we suggest replacing it.
FAQ
Do I send you my ECU?
Yes, or bring it in person. It ships back fully insured by overnight UPS/DHL.
Can I put a 2023 ECU in my 2024 car?
No. Hyundai changed the ECU for 2024, so 2024 owners cannot use 2023 ECUs.
Is the tune customizable?
Yes, fully customizable. Local customers also get a free flash back to stock, a few-minute OBD job.
Does anti-lag work on the 6-speed?
No, anti-lag is DCT only. The RPM shift, pop map and flame tune are available on both transmissions.
Use and liability notice
Stage 2 and 3 raise OEM temperature limits, an OEM safety that all tuners must raise for the car to make power. N75 Motorsports takes no responsibility for damage caused by lifted temperature limits, for example where the car lacks the supporting mods and the engine runs extremely hot.
