Fits: 2021+ Hyundai Elantra N Line, 2021+ Hyundai Kona N Line, 2021+ Hyundai i20 N, 2021 Hyundai Sonata 1.6T (Gen 4), 2021 Kia K5 GT Line 1.6T, 2021+ 1.5T variants sold in South Asian and African countries, and any other CPEGD3.20.1 or CPEGD3.20.2 ECU; 1.6T Smartstream, CPEGD3 ECU.
What this is
A two-stage ECU calibration for the Hyundai/Kia 1.6T Smartstream (the Gen 4 1.6T Gamma) and its CPEGD3 ECU, developed in Canada by N75 Motorsports: 15–35 whp over stock, depending on the stage. Delivered as a file for your EK1 device or our PC-based flash tool, or flashed onto the ECU you send in.
From the ECU data, the stock calibration requests a peak of 3 degrees of ignition timing at 6000 RPM and 0 degrees at 5000 RPM, and its boost maps are conservative for this turbocharger. Boost and ignition timing are where most of the gain in ECU tuning comes from.
Tune options
| Option | Target and output | Required mods and fuel |
|---|---|---|
| Stage 1 | 2–3 psi over stock (17–18 psi request). 15–20 whp gain. Torque request, limiters and monitoring raised; ignition timing added for premium fuel; AFR optimized. | Premium pump fuel. |
| Stage 2 | 22 psi request from the ECU. 25–35 whp gain (20–25 whp on the 1.5T). Everything in Stage 1 plus component protection altered per vehicle and mods, max wide-open throttle, altered warm-up and cool-down, VVT optimization. | Ignition timing is added for premium fuel only; E30 blend or WMI suggested. Component protection and the calibration are adjusted to the mods you list at order. |
Choose Stage 1 for a car on premium pump gas, and Stage 2 when you can run an E30 blend or WMI and want the full boost and VVT work. We suggest keeping boost around 20–21 psi on this turbo and do not recommend 23 psi.

- Boost: 17–18 psi request on Stage 1, 22 psi on Stage 2.
- Both stages: torque request, limiters and monitoring raised; ignition timing increased for premium fuel only; AFR optimized.
- Stage 2 only: component protection altered per vehicle and mods; maximum wide-open throttle; altered warm-up and cool-down; VVT optimization.
- On request: raised idle in Sport or N mode only; crackle and pop.
How we tune
We developed this calibration for over 18 months before release, and our CPEGD3 mappack has over 1,000 maps. The world's fastest Kia Forte GT runs our tune. Its CPEGD2.20.3 ECU is the most similar to the CPEGD3, and we have developed it since 2019. The 2020 Hyundai Veloster Turbo 1.6 runs the same ECU. Our own i20 N in Europe gained 30–35 whp. Comparing this turbo with its other three generations, we set a boost level that makes good power and still allows good ignition timing, for a stronger powerband.
Before you order
- Fuel: premium pump fuel on Stage 1; ignition timing is added for premium fuel only; E30 blend or WMI suggested on Stage 2.
- Oil: Motul Power 5w40 is recommended on every N75-tuned Hyundai and Kia; it sustains the higher temperatures of a tuned engine, an extra step to keeping it healthy for years.
- EK1 users: the CPEGD3 bench kit is required to flash this ECU with an EK1.
- Unlisted cars: email us the ECU label first.
FAQ
Do I have to send in my ECU?
No. We deliver a file for your EK1 device or our PC-based flash tool; to send in the ECU, email info@n75motorsports.ca first for the shipping instructions.
How much boost does Stage 2 run?
Stage 2 requests 22 psi from the ECU. We suggest keeping boost around 20–21 psi and do not recommend 23 psi, because the turbo falls off in the upper RPM range and a boost-heavy map stresses it. On the i20 N and Elantra N Line the turbo holds only about 14–15 psi at redline, and ignition timing keeps the powerband smooth when it falls off.
Is my car supported if it is not listed?
Yes, if it has a CPEGD3.20.1 or CPEGD3.20.2 ECU. If it has a newer 1.6 L engine, check the label on the ECU itself and email it to us before ordering.
Can I go back to stock?
The file changes calibration data only, and the car can be flashed back to stock with the same tool.
Use and liability notice
The Stage 2 map is built for the fuel and mods you list at order. N75 Motorsports takes no responsibility for damage where fuel or oil is wrong, mods differ from what was listed at order, or a pre-existing fault worsens on a tune.
Let customers speak for us
Solid shipping ,good communication ,great product 5stars all the way
First let's preface I have tried three other tuners. Not bad mounting or name dropping as they all were solid tunes. But Daniel just has that magic touch when tuning the 1.6 platform.
The car has a buttery smooth power band making the car feel like a larger displacement six cylinder over a turbo charged car. Plenty of fun to be had at any speed or RPM range.
He will take the time to get you dialed in perfectly for your car. No canned tunes here folks. And if you are a EK1 user three tunes for the price of one simply can't be neat.
I received the Stage 2 tune. Here are my thoughts:
- The shifts are buttery smooth
- I love the auto shift @2000rpm when cruising around town; saves me an extra 2-3mpg overall
- Driving in traffic is a dream now, much better than stock. I don't even hear that annoying shifting fork anymore, lol
- Any and all DCT slips are gone
- The increase in torque limit! This opened up my N75 Stage 3 ECU tune; I can feel the difference. The last time I dynoed, I got 289 lb-ft of torque. But it feels much more substantial than that!
- The clamping force is unreal. I did a run from a dig, and it hooked and slammed through the gears all the way to 7k rpm in each gear. Amazing.
Conclusion: This TCU tune is a must-have. If you have an N75 ECU tune, it is an absolute game-changer! Especially with the Redline MT-LV fluid that I'm running. I can't wait to get my retune with water meth injection. Daniel and the rest of the N75 team are the best!
Works like suppose to be fast delivery after installation 5 minutes drive TPMS sensors lights off everything is normal like from factory 👍👍👍

Product was very easy to install and what a difference in shifting also n75 was super awesome to deal with will shop here again
After using the N75 tune for a couple of months, I can confidently say that it offers the best value for your money on the market. I've tried SXTH and LAP3 tunes before, but since switching to N75, I won't look back. With top-notch customer support, it ensures your car performs better, turning heads at every car meet.
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!
Daniel's tuning and customer service makes this product a 10 out of 10. I'm new to tuning and he made the process a breeze. I literally laughed out loud when I first drove the car after installing the stage 2 tune. I still can't believe the difference.
Love the intake, fitment is superb, instal was easy and best of all n75’s customer support is stellar and way above average!
