What's New in KDMLink
1.1.2
July 1, 2026
Fixed - Boost gauge accuracy. The boost/turbo gauge could spike erratically (jumping to 15–20 psi during light throttle) and read large negative values at idle. The app now reads boost from the correct engine signal, so the gauge tracks smoothly and accurately from idle vacuum through full boost. Most noticeable on the Elantra N (DCT). - Updated vehicle profiles for Elantra N, Kona N, and Veloster N. Existing installs receive the corrected boost decoding automatically via a vehicle-data update — no re-pairing needed. Improved - Added a filter for invalid CAN frames so momentary sensor dropouts no longer flash bad boost readings.
