Chip tuning for Opel Astra 1.5 Turbo D 122 hp ECU
Opel Astra (2019) 1.5 Turbo D 122 hp — mass-market diesel engine of the passenger segment of the Stellantis group (Германия, 1862). Stage 1 chip tuning raises power from 122 to 150 hp (+28 hp, +23%) and torque from 300 to 340 Nm (+40 Nm). ECU — Bosch MD1CS003. Flashing method: OBD or Bench depending on the unit's protection. The ZF 9HP48 TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 2 configurations · 2 ECU variants. A 2019 diesel — a modern platform protected by RSA + checksum encryption; top models require BDM/JTAG.
Opel has been part of the Stellantis group since 2017 (formerly GM Europe). Opel and Vauxhall (UK) are the same line-up under different names. Opel OPC is the performance division, producing high-output turbo versions. The factory calibration on Citroen diesels is conservative, leaving headroom for Stage 1.
On Opel diesels, Stage 1 delivers a noticeable torque gain. Within Stellantis, ECUs are standardised, so Opel files (from 2017 on) often work on Peugeot/Citroen. Protection on modern Opel models uses Tricore TPROT, so Bench is required. The French Citroen community has a large pool of ready-made Stage files. Mid-range Citroen engines are a mainstream chip tuning subject in Europe.
The TCU rarely needs recalibration up to Stage 1+ on mainstream Citroens. Citroen uses Aisin automatics and the group's own automated gearboxes. EAT8 is Stellantis's proprietary 8-speed gearbox.
