Fits: Hyundai Veloster N, 6-speed manual and DCT.
What this is
An in-house ECU calibration for your Veloster N, send-in service. You ship your ECU to N75 Motorsports in Mississauga, Ontario, Canada, we calibrate it to the stage and options you chose, and it goes back to you with full insurance coverage and overnight UPS/DHL shipping to reduce downtime.
Stages
Stock output is around 225–235 whp. All figures below are for the Veloster N.
| Stage | Power | Required mods |
|---|---|---|
| Stage 1 | 265 whp / 280 ft-lbs | Heat range 9 spark plugs. HPFP upgrade recommended. |
| Stage 2 | 280 whp / 295 wtq | Heat range 9 spark plugs; HPFP upgrade recommended; any air intake (we use AFE). |
| Stage 3 | 295 whp / 320 ft-lbs | Heat range 9 spark plugs; intake; HPFP upgrade; FMIC upgrade; downpipe and catless or high-flow exhaust. |
| Stuffed Turbo / EN Turbo tune | Not rated | For cars running a stuffed turbo or an EN turbo swap; supporting mods not listed. EN turbo cars need the 7000/7200 RPM shift option, since the bigger turbo makes boost higher in the rev range. |
| Flame tune | Not rated | The car must be catless. |
Stage 1 is made for an otherwise stock car and corrects issues with the OEM Hyundai tune such as AFR, for better fuel economy. Stage 2 is made to last the life of the car. Stage 3 is the high-boost, high-torque map. The Flame tune adds pop flames on rev; it is an aggressive calibration and hard on the motor and turbo.
360 whp / 380 ft-lb on a Veloster N DCT (Dynojet, SAE correction).
Options explained
- 7000/7200 RPM shift (any stage): shift point raised to 7000 RPM on DCT cars and 7200 RPM on 6-speed cars.
- N Mode pop map: pop sound changed through the ECU, more aggressive than OEM, N Mode only like OEM. A high-flow catted or catless downpipe is recommended.
- 2-step style anti-lag (DCT only, chosen under the pop map option): aggressive pops and flames during launch control, spinning the turbo up to 17–18 PSI on the line. Samples are on our Instagram.
How it works after you order
- Order with your stage and options.
- Send your ECU to N75 Motorsports in Mississauga, Ontario, Canada. Local customers can also be recalibrated over the OBD2 port.
- We calibrate your ECU in-house to the stage and options you chose.
- Your ECU ships 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, our own N-series mappack and a worldwide tuner network: 7000/7200 RPM shift, pop flames and more. 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 increased in optimized areas 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 is typically around 18–20 PSI; lifted to around 25 PSI, removed completely on Stage 3 and up, where we run some engines on hybrid turbos at very high boost.
- 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%, for street and track cooling.
- Fault prevention: primary O2 sensor monitoring never triggers a fault code; no fault codes are deleted.
- Octane learning: disabled, or left on if you ask.
- 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 through torque and TCU-related maps.
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 we suggest replacing it to avoid issues.
FAQ
Do I send you my ECU?
Yes. Ship it to N75 Motorsports in Mississauga, Ontario, Canada. Local customers can also be recalibrated over the OBD2 port.
Can I go back to stock?
Local customers get a free flash back between the stock map and the tuned map. The OBD2 flash takes 3 minutes and our flash tool stores your files.
Is the tune customizable?
Yes, our tunes are fully customizable. Octane learning can be disabled or left on, your choice.
Use and liability notice
Stage 2 and 3 raise the OEM allowed-temperature limits for the exhaust and intake models so the car holds power toward redline. 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.
