Mercedes-Benz B 160 CDI Stage 1 Remap

Name: Mercedes-Benz B 160 CDI Stage 1 Remap
Brand: Mercedes-Benz

On Mercedes-Benz B 160 CDI diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.

How much bhp does Mercedes-Benz B 160 CDI chip tuning add?

It depends on the generation and the stock output. 160 CDI engines with 90 bhp reach 135 bhp with a Stage 1 remap; the largest gain is +45 bhp (W246 160 CDI 90hp). Pick your version in the table below.

About the common-rail turbo diesel engine

This vehicle uses a common-rail turbo diesel engine. In this technology fuel is sprayed from a shared high-pressure rail through electronically controlled injectors, and the ECU constantly manages injection quantity, timing and boost pressure.

How a Stage 1 remap works on the Mercedes-Benz B 160 CDI

A Stage 1 remap recalibrates injection quantity, rail pressure, boost pressure and torque limiters together. Torque gains are clear on diesels and pull improves at low and mid revs. Smoke, exhaust temperature and turbo speed limits are kept.

Pre-remap checklist

Injector condition and leak-off test.
Leaks in the turbo and boost circuit.
EGR valve and, on DPF cars, the differential pressure sensor.
Clutch and dual-mass flywheel; the extra torque can cause slipping.

Catalogue figures assume a healthy engine; diagnosis first, then software.

This section is based on GP Power ECU workshop experience; the power and torque figures come from the catalogue measurement above.

Frequently asked questions

How much bhp does Mercedes-Benz B 160 CDI chip tuning add?

It depends on the generation and the stock output. 160 CDI engines with 90 bhp reach 135 bhp with a Stage 1 remap; the largest gain is +45 bhp (W246 160 CDI 90hp). Pick your version in the table below.

What is the difference between Stage 1 and Stage 2 on the Mercedes-Benz B 160 CDI?

Stage 1 is software only: no part of the car is changed and the figures in the table apply to this software. Stage 2 is software prepared for hardware changes such as the exhaust, intercooler or intake; the hardware comes first, then the software.

Will chip tuning damage the engine?

No. Values stay inside the safety margin the manufacturer leaves; engine, gearbox and turbo limits are not exceeded. Every file is verified with a road test and data logging. If the car needs maintenance first (worn injectors, blocked filter, weak clutch) we tell you before starting.

Will my fuel consumption go up?

With the same driving style it usually drops, because you hold the same speed at lower revs and less throttle. If you use the extra power, consumption naturally rises. It is down to your right foot.

How long does it take? Do I leave the car?

Most cars take 1–2 hours and you get the car back the same day; no need to leave it. Some models need the ECU removed, which takes longer — we tell you when booking.

Can I go back to stock later?

Yes. The original file is read and archived before any work. We restore the factory software free of charge whenever you ask.

What is checked on the Mercedes-Benz B 160 CDI before remapping?

Before working on the common-rail turbo diesel engine we check: Injector condition and leak-off test. Leaks in the turbo and boost circuit. EGR valve and, on DPF cars, the differential pressure sensor. Clutch and dual-mass flywheel; the extra torque can cause slipping. If something needs attention, maintenance comes first; the remap is applied to a healthy engine.
