Chip tuning for Smart ForFour 1.0i (smart) 71 hp ECU
Smart ForFour (2014) 1.0i (smart) 71 hp — mass-market petrol engine of the passenger segment of the Mercedes-Benz Group AG / Geely (с 2020 — JV) group (Германия, 1926). Stage 1 chip tuning raises power from 71 to 79 hp (+8 hp, +11%) and torque from 91 to 106 Nm (+15 Nm). A petrol engine built in 2014 — a Tricore platform without strong protection; OBD access works.
Smart is positioned as an urban premium micro-car brand. Smart specialises in micro urban cars (ForTwo, ForFour). The Smart #1 and #3 are the new generation of electric crossovers built on the Geely platform. Mid-generation petrol models use standard OBD flash. Brabus is an independent Mercedes tuning house specialising in top-model upgrades. The AMG 'one engineer, one engine' principle means each engine is built by a single craftsman whose signature appears on the plaque.
On Mercedes up to the recent generation, Stage 1 OBD flash is available. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. In the Mercedes city segment, Stage 1 is more about comfort and responsiveness than power. On low-output Mercedes engines, Stage 1 is safe and does not over-stress the hardware. On naturally aspirated Mercedes engines without a turbo, the main effect is on throttle response.
