Chip tuning for Mercedes E 230 (2.5i) 204 hp ECU
Mercedes E (2006 - W211) 230 (2.5i) 204 hp — premium petrol engine of the passenger segment of the Mercedes-Benz Group AG (Mercedes-Benz, AMG, Maybach, Smart, EQ) group (Германия, 1926). Stage 1 chip tuning raises power from 204 to 220 hp (+16 hp, +8%) and torque from 245 to 269 Nm (+24 Nm). A petrol engine built in 2006 — the era before widespread firmware encryption, OBD flash without complications.
4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. The Mercedes-Benz Group AG (Daimler AG until 2022) comprises Mercedes-Benz, AMG, Maybach, Smart and the EQ line. AMG is the performance division of Mercedes (since 1967), building engines on the 'one man, one engine' principle in Affalterbach. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1. High-output Mercedes turbo petrol engines are the flagship models, and Stage 1 delivers a solid gain. On older-generation Mercedes petrol engines, Stage 1 is flashed over OBD without Bench.
The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. The Mercedes premium segment is a high-output platform with Stage 2 potential. High-output Mercedes engines are premium-class with solid headroom for Stage 1. On modern high-output Mercedes, Bench reading is often required because of the encryption.
