Chip tuning for Jeep Wrangler 4xe (2.0T) 375 hp ECU
Jeep Wrangler (2018 - JL) 4xe (2.0T) 375 hp — mass-market hybrid engine of the passenger segment of the Stellantis group (США, 1941). Stage 1 chip tuning raises power from 375 to 415 hp (+40 hp, +11%) and torque from 637 to 697 Nm (+60 Nm). ECU — Siemens/Continental GPEC4. Flashing method: OBD or Bench depending on the unit's protection. The ZF 8P75PH TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 2 configurations · 2 ECU variants.
Trail Rated is Jeep's signature certification for off-road capability. The Jeep range comprises the Wrangler, Cherokee, Grand Cherokee, Compass, Renegade, Gladiator and Avenger. Jeep shares platforms and engines with Dodge, Chrysler and Ram. Jeep PHEV variants combine a turbo engine with an electric motor. The Jeep Avenger is a compact electric car on the Stellantis platform. Jeep 4xe is the badge for the brand's PHEV models (Wrangler 4xe, Grand Cherokee 4xe).
Protection on modern Jeep models uses Tricore, so Bench is required for the top models. The Jeep community in the US offers a large pool of ready-made Stage files for off-road use. In Europe the Jeep community is growing thanks to the diesel versions. Top-tier Jeep Trackhawk/SRT engines sit at the power ceiling of American SUVs; the gain is significant.
Aisin transmissions feature on the compact crossovers. Jeep uses the ZF 8HP on premium models. The Trackhawk and SRT come with a reinforced ZF 8HP.
