Chip tuning for Mercedes B 150 95 hp ECU
Mercedes B (2005 - W245) 150 95 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 95 to 100 hp (+5 hp, +5%) and torque from 140 to 150 Nm (+10 Nm). ECU — Siemens/Continental SIM266. Flashing method: OBD or Bench depending on the unit's protection. A petrol engine built in 2005 — 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. Low-output Mercedes petrol engines are naturally aspirated, so the gain is modest but safe. 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. 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.
Frequently asked questions
How much horsepower does Stage 1 add for the Mercedes B 150 95 hp?
Stage 1 chip tuning on the Mercedes B 150 95 hp boosts engine output by 5 hp: from 95 to 100 hp. Torque rises from 140 to 150 Nm (+10 Nm).
What changes in the Mercedes B ECU after Stage 1?
Stage 1 on the Mercedes B 150 95 hp is a software ECU calibration with no hardware changes. The key maps (boost/ignition/lambda/torque) are adjusted while factory tolerances are preserved. The gain is +5 hp with no hardware changes.
Is Stage 1 safe for the low-output Mercedes B 150 95 hp?
Yes, Stage 1 on the low-output Mercedes B 150 95 hp delivers a moderate but genuine gain — without overstressing the hardware. On base naturally aspirated engines the effect is felt mainly as improved throttle response and a stronger mid-range.
How does Stage 2 differ from Stage 1 on the Mercedes B 150 95 hp?
Stage 2 for the Mercedes B 150 95 hp is Stage 1 plus hardware changes: a downpipe, a larger intake and a performance intercooler. The gain is considerably higher, but it requires professional component selection.
What control unit does the Mercedes B 150 95 hp run?
The control unit of the Mercedes B 150 95 hp is the Siemens/Continental SIM266. Before flashing, the engineer identifies the exact revision and selects the write method.
Does Stage 1 void the warranty on the Mercedes B?
Stage 1 on the Mercedes B voids the factory warranty on the engine and transmission — this is standard for all manufacturers. CHIPOK provides its own warranty on the quality of the remap.
How quickly is chip tuning of the Mercedes B 150 95 hp done?
The full remap cycle for the Mercedes B — from reading to writing the final file — takes 30-90 minutes depending on the ECU access method. The file is prepared at CHIPOK in 5-30 minutes.
Can you return to stock after Stage 1 on the Mercedes B?
The original Mercedes B ECU is always saved before flashing. Rolling back to the factory firmware is done with the same programmer in 25-30 minutes.
