Hyundai Kona N ECU Calibration on Spare ECU

N75 Stage 2 ecu + Pop map

Received Stage 2 + Pop map on spare ECU for my 2023 Kona N. Daniel was very helpful through the whole ordering process. And was able to arrange everything I was looking for. I notice a bunch of tiny little differences that make the driving experience a lot more smoother and enjoyable. WOT is a lot more smoother with no dips in performance. Holding boost and power mid to high RPM. With noticeable higher torque at lower RPM. And it definitely pins me to my seat much more, this thing it pulls!! I opted in the pop map. And I noticed right away that it is much more aggressive in a good way. Especially that I removed my resonator. And driving in eco and normal mode is still chill. Also, I'm so happy the octane learning is gone. And that my bluelink still works. Install is simple and straightforward as well.

Stage 1 Spare ECU

Great communication from N75 about all my questions regarding the tune. Packaged well and installation was a straight forward process. Going from stock to Stage 1 was a very noticeable difference. 10/10

Stage 2 spare ecu

I installed the spare ecu with stage 2 tune back in November of 2025. Did the required upgraded prior to installation. I also run 93 octane at all times. I have had zero issues whatsoever and the Kona runs flawlessly. Very linear power across the rpm range. Kona runs hard and strong. Daniel has been very responsive in any questions I’ve had and a stand up guy. Could not be happier. Thank you N75.
