Mercedes B180 1.6T

Driveability issues with the stock engine mapping

Never has there been a Mercedes model with a bigger need for a remap than the B180. Because the engine lacks power for the car’s weight and the mapping does nothing to conceal it.
As much as we love Mercedes, the B180¬†BlueEFFICIENCY with 122hp is almost undriveable. There is a huge delay in the throttle pedal’s response and almost 3/4 of its travel do nothing to speed up the car. It is probably by far one of the worst behaving cars in the whole range. Not that much because it lacks power (which unfortunately really does). But because torque is non existent under daily driving conditions. It is very hard to describe how frustrating driving it can become, specially in city conditions.
All these problems are addressed with the Stage 1 remap. Throttle response is direct, the turbo spools and there is actually usable torque for the driver even at lower throttle pedal angles.
The Stage1 ECU remap adds a very big amount of torque overall, which significantly improves the car’s behaviour. As can be seen on the dyno results, it is like a different car.
