Chip tuning for Volkswagen Polo 1.5 TDI 90 hp ECU

Volkswagen Polo (2009 - 6R) 1.5 TDI 90 hp — mass-market diesel engine of the passenger segment of the Volkswagen Group (VAG) — материнская компания group (Германия, 1937). Stage 1 chip tuning raises power from 90 to 130 hp (+40 hp, +44%) and torque from 230 to 300 Nm (+70 Nm). In the CHIPOK database: 2 configurations. The 2009 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.

The ID line is VW's dedicated series of all-electric models. VAG is Europe's largest automotive group by production volume. Volkswagen is Germany's largest carmaker, founded in 1937 in Wolfsburg. The factory calibration on VW diesels is conservative, leaving headroom for Stage 1. DPF/SCR with AdBlue is standard on all Euro-6 VW diesels. TDI is Volkswagen's badge for direct-injection turbo-diesel engines.

APR, Revo and Stage 1+ are the leading tuning brands for VW. Stage 1 on VW is typically a quick, standard turnaround. On GTI and R models, Stage 1 works fine on stock hardware. Low-output VW engines sit in the compact segment, and Stage 1 is safe on them. On naturally aspirated VW engines the main effect is sharper throttle response. In VW's city-car segment, Stage 1 is more about drivability than outright power.
