How the process works

  1. You send over the car details, modifications and your goals.
  2. We recommend the right ECU route or tuning solution.

Why Japanese ECU tuning is different

Japanese performance cars often need more than a simple generic map. Older platforms may need live mapping, board-based solutions, piggyback systems or a properly configured standalone ECU. The goal is always the same: make the car behave correctly, safely and with the strongest usable performance for the setup.
