Chip tuning for Toyota Yaris 1.5 VVT-iE 125 hp ECU
Toyota Yaris (2020) 1.5 VVT-iE 125 hp — mass-market petrol engine of the passenger segment of the Toyota Motor Corporation group (Япония, 1937). Stage 1 chip tuning raises power from 125 to 130 hp (+5 hp, +4%) and torque from 153 to 160 Nm (+7 Nm). A modern petrol engine built in 2020 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.
Lexus is Toyota's premium sub-brand. The GR Supra uses the BMW B58 straight-six, an unusual turbo engine for Toyota. Mid-range Toyota petrol engines see a modest Stage 1 gain due to their naturally aspirated design. Toyota has historically focused on naturally aspirated, high-compression engines.
The GR models (Yaris GR, Supra) have a growing tuning culture. Toyota has an active JDM tuning community (GR Supra, GR Yaris, GR86). The Denso ECU is a locked Toyota platform, and most models do not respond to standard chip tuning. Mid-range Toyota models use high-compression naturally aspirated engines, so Stage 1 yields a modest gain. The locked Denso platform requires a dedicated tuning toolset.
