Chip tuning for Dodge Charger 6.4 V8 SRT8 477 hp ECU
Dodge Charger (2011 - LD) 6.4 V8 SRT8 477 hp — mass-market petrol engine of the passenger segment of the Stellantis group (США, 1925). Stage 1 chip tuning raises power from 477 to 500 hp (+23 hp, +5%) and torque from 637 to 668 Nm (+31 Nm). This engine ships with different ECU variants: Siemens/Continental GPEC2, Siemens/Continental GPEC2A. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. The ZF 8HP70 TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 3 configurations · 3 ECU variants. A petrol engine built in 2011 — a Tricore platform without strong protection; OBD access works.
The Hemi V8 is Dodge's iconic muscle-car engine. The Hellcat and Demon are Dodge's top segment, with extreme power output. Dodge shares platforms with Chrysler, Jeep and Ram. The Hemi V8 is the proprietary Chrysler/Dodge engine for the top models. The top Hemi Hellcat offers significant potential with hardware. The Chrysler petrol range is mainly the Pentastar V6.
The Hellcat confidently reaches Stage 2 with hardware. The US Chrysler community has a large pool of ready-made Stage files. HP Tuners is the leading tool for Chrysler/Dodge. Top Chrysler/Dodge Hellcat engines sit at the power ceiling of the American mass market.
The TCU rarely needs recalibration up to Stage 1+. Hellcat models use a reinforced ZF 8HP. Chrysler uses the ZF 8HP on its top models.
