Rapid Bike Easy
This is a plug and play solution that is very easy to install and also very affordable. Most especially modern engines run too lean in the lambda part, this is also called the 'closed loop' part, because this part is controlled by the sensor and then adjusted by the ECU to a (too lean) mixture.
This "closed loop" part is typically around low rpm and in the lower throttle positions, which is however the part in which people mostly drive on public roads. Problems such as: not picking up nicely, not being able to drive a constant speed smoothly, on/off reaction are largely caused by this.
The Rapidbike easy comes between the plug of the lambda sensor and the plug of the ECU and gives a different signal that makes the engine run a little less poor and thus better. The advantage is that the engine usually runs a lot better in the lower ranges. And that in a simple way and for a low price. For a really extensive tuning it is better to go for the Rapidbike EVO or an ECU remapping.
