Technical Information
About the remap
Stage 1 chip tuning for the Subaru Impreza 2.0T WRX 225hp increases power from 225 to 261 hp (+36 hp, +16%) and torque from 300 to 360 Nm. Turbocharged petrol engines respond exceptionally well to ECU optimization – adjusting ignition timing, boost pressure, and fueling maps unlocks the hidden potential built in by the manufacturer.
The remap is performed on the Denso 68HC16 ECU (engine code EJ20) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, CMD CMDFlash, Dimsport New Genius. Results are verified with a dynamometer measurement.
Every vehicle undergoes full diagnostics before and after the remap. We keep a backup of the original ECU calibration and guarantee the option to revert to stock settings at any time. JVK PRO is a professional chip tuning service in Riga with 16 years of experience.
