Fits: Kia Forte GT (K3) 2020 onward, Hyundai Veloster Turbo (VT2) 2019–2022, Hyundai Kona 1.6T 2019–2022 (non N Line), Hyundai Tucson 1.6T 2017–2020, Kia Proceed; Kefico CPEGD2.20.3 / CPEGD2.20.4 ECU.
What this is
A calibration file for the 1.6T Gamma T-GDI, developed and tuned in Canada by N75 Motorsports, delivered for your flash tool.
Over 250 whp and over 300 wtq on the OEM turbo; close to 300 whp on our upgraded turbo on 91 octane.
The world's fastest Kia Forte GT runs our tune. It is the only Forte GT to run a 12-second 1/4 mile: 12.88 on the OEM turbo, OEM wheels and tires, with the mods listed below plus WMI and a downpipe. The same car ran 13.13 @ 109 mph before that, and a Forte GT on our WMI tune ran 13.465 @ 104.74 mph on the OEM turbo and intercooler.
The 12-second run: OEM turbo, OEM wheels and tires, N75 tune with WMI and a downpipe.
Tune options
| Option | Boost target and output | Required mods and fuel |
|---|---|---|
| 91 Octane | 21–23 psi. 240 whp with axle-back, FMIC and intake. Moderate timing advance, VVT adjustment. | Shell V-Power 91, zero ethanol; oil catch can; HKS M45XL or NGK heat range 9 racing plugs; N75 Race Valve. |
| 91 Octane + Pop Tune | 91 Octane plus pops and bangs on decel. | As 91 Octane, plus a downpipe and an Xforce mid pipe (this platform has two cats). |
| 100 Octane "Race Gas" | 24–25 psi. 255 whp with full catless exhaust and our FMIC. Aggressive timing advance, VVT adjustment. | Shell V-Power 91 plus a full can of Race Gas Ultra or VP MS109, or Boostane Professional; full exhaust, FMIC, full bolt-ons; oil catch can; HKS M45XL or NGK Racing R2556B-9/-10; N75 Race Valve and any GFB BOV. |
| WMI Tune | Water/methanol injection map. | A working WMI kit; confirm fuel, plugs and hardware with us by email. |
| WMI Tune + Pop Tune | WMI Tune plus pops and bangs on decel. The 12.88 world-record Forte GT ran this combination, WMI with a downpipe, on the OEM turbo. | As WMI Tune, plus a downpipe and an Xforce mid pipe. |
| Race Track Lap Map (extreme mapping) | 26–28 psi. As much power as the OEM engine and turbo can make; limiters removed; 400+ maps modified. | Full bolt-ons plus the 100 Octane fuel, plugs, catch can, Race Valve and BOV. Not supported through EK1 devices. |
91 Octane is our everyday calibration; customers have over 75,000 miles on it. 100 Octane is for cars on race fuel or octane booster every tank. The Race Track Lap Map is the 100 Octane map pushed further: limiters removed, the turbo worked hard, faster turbo wear. We built it because customers asked for an extreme map. We do not recommend it; order it only if you want the most power the OEM turbo can make and accept the faster turbo wear.
Options explained
- Add HR9 spark plugs: a set of heat range 9 plugs with your order; choose Yes unless you already run a plug listed below.
- Pop tune: any added pops need a downpipe and an Xforce mid pipe, because this platform has two catalytic converters; a stock cat risks cat damage and, worst case, engine damage.
- 7000 RPM shift (6-speed only): on request on 6-speed cars; not available on DCT cars with 1.6T Kefico tuning.
- Idle lift, speed-limiter removal, DTC removal: on request, e.g. a downpipe code or a BOV without a solenoid.
- Turbo upgrade tunes: tuned separately for our Stage 1 turbo (larger K04 compressor, billet wheel over 51 mm inducer) and Stage 2 turbo, which targets 25 psi for approximately 310 whp with catless exhaust and our FMIC kit; email us.
How it works after you order
- Email info@n75motorsports.ca before buying with your car, year, transmission and mods.
- Order your tune option and plug choice, specifying the vehicle.
- We deliver the tuned file. This listing is the file only; a flash tool must be bought separately or added to your order. Email us for the right tool for your car.
- We may cancel an order for a car with a mechanical fault.
Calibration features
Developed in Canada with WinOLS; click the badge to verify our licence with EVC.
- Warm-up protection: 50% power until oil temperature reaches 50 °C, 70% at 60 °C and 100% at 70 °C, so high-boost maps only apply boost on a warm engine.
- Torque management: all torque maps optimized for your car's torque-request model.
- WOT maps: wide-open-throttle maps optimized for a smooth powerband.
- Ignition timing: optimized per map and fuel grade.
- Turbo management: spool and boost maps set for a smooth powerband to redline.
- AFR: the factory map runs very rich at high RPM; corrected for more power and less fuel (91 octane required).
- VVT: cam timing changed for more power.
Tune safety is most important to us. We do not disable ECU safeties.
Before you order
- Fuel: Shell V-Power 91 with zero ethanol. Ethanol absorbs water from the storage tank to your fuel tank, and third-party tests put 90/10 premium closer to 85/15.
- Plugs: 91 Octane: HKS M45XL or an NGK heat range 9 racing plug (R2556B-9). 100 Octane and Race Track Lap Map: HKS M45XL or NGK Racing R2556B-9 or R2556B-10.
- Oil catch can: required on the 91 Octane, 100 Octane and Race Track Lap maps.
- Daily driving on 100 Octane: even on race gas it wears the turbo faster; the bearings were not designed for the shaft speed 25 psi needs. This map needs race-gas octane every tank: Shell 91 with Boostane Professional, or a full can of Race Gas Ultra.
- Race Track Lap Map: not supported through EK1 devices; email us about the flashing method before ordering this map.
FAQ
Do I send you my ECU?
This listing is the calibration file; you flash it with a flash tool bought separately or added to the order. Email us before ordering if you are unsure how your car will be flashed.
Can I run the pop tune with a catalytic converter?
This platform has two cats, so a pop tune needs a downpipe and an Xforce mid pipe. Many catted cars have been pop-tuned against our advice, some with 25,000 km without issue. The risk is cat damage and, worst case, engine damage.
Can you remove fault codes?
Yes, any DTC you ask for, such as a downpipe code or a BOV without a solenoid.
Use and liability notice
High-boost maps need the listed supporting mods, fuel and plugs. N75 Motorsports takes no responsibility for damage where they are missing, fuel or plugs are wrong, the stock catalytic converters are kept on a pop tune, or a pre-existing fault worsens on a tune.
