Chip tuning for Subaru Legacy 2.0 D 150 hp ECU
Subaru Legacy (2009) 2.0 D 150 hp — mass-market diesel engine of the passenger segment of the Subaru Corporation (Toyota владеет 20%) group (Япония, 1953). Stage 1 chip tuning raises power from 150 to 175 hp (+25 hp, +17%) and torque from 350 to 400 Nm (+50 Nm). Diesel engines built in 2009 — the era of classic Common Rail without strong encryption.
STI (Subaru Tecnica International) is the performance division that builds the WRX STI. Subaru uses permanent all-wheel drive (AWD) on most of its models. The WRX STI is Subaru's iconic rally model. Subaru diesels are rare and were aimed mainly at the European market. Subaru Boxer diesels are a niche chip tuning segment. Subaru has unique flat diesel engines (Boxer Diesel).
The Subaru community in JDM and rally culture is the largest for the WRX/STI. Mid-range Subaru models use naturally aspirated Boxer engines with a conservative calibration.
