About the remap

Stage 1 chip tuning for the Audi S3 2.0 TFSI 310hp increases power from 310 to 367 hp (+57 hp, +18%) and torque from 400 to 480 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 Siemens Simos 12 ECU (engine code CJXB) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, Autotuner Autotuner, ByteShooter Toolbox and other professional tools. 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.
