Toyota ProAce (2020) 1.5 D-4D 120 hp — mass-market diesel engine of the passenger segment of the Toyota Motor Corporation group (Япония, 1937). Stage 1 chip tuning raises power from 120 to 150 hp (+30 hp, +25%) and torque from 300 to 340 Nm (+40 Nm). A modern diesel built in 2020 — a generation with encrypted firmware (Tricore TPROT) that often requires a Bench read.
Lexus is Toyota's premium sub-brand. Mid-range Toyota diesels are a high-volume chip tuning subject for pickups. On modern Toyota diesels, top models often require a Bench read. D-4D is Toyota's badge for its turbo diesels.
Toyota has an active JDM tuning community (GR Supra, GR Yaris, GR86). Stage 1 on Toyota diesels delivers a noticeable torque gain, ideal for pickups. The GR models (Yaris GR, Supra) have a growing tuning culture. 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.
