KDMLink

The telemetry app built for the way you actually drive your N.
KDMLink pulls live data straight off your car's C-CAN bus — the real network where your Veloster N, Elantra N, and Kona N talk to themselves. This is the data a standard OBD-II scanner physically can't reach. Boost, timing, gear, steering angle, N mode state, and 80+ more signals, streaming to your phone in real time.
If you've ever wanted to actually see what your N is doing on a backroad or at the track instead of guessing, this is for you.
