How it Works
Installed more modifications on your Veloster N? Looking to get more power? Upgrade your existing calibration to a higher stage! Our ECU Calibrations are guaranteed to get you a great increase over stock power levels (individual results may vary). Calibration upgrades require ownership of a SXTH Spare ECU.
Bought a used SXTH spare ECU from someone and need it reset to work with your vehicle? No problem! Select the "Spare ECU Reset" option and follow the instructions below.
Your vehicle must be in good, working condition. We reserve the right to cancel or adjust the timeframe for any customer with a vehicle not in such condition. We may ask prior to scheduling for proof of condition. We cannot and will not calibrate a vehicle that does not run well. There is no "calibrating around it". We will not make suggestions for repairs if it does not run well prior to calibrating. You will need to consult a local shop for repairs.
