Control method for the mixture ratio in a multi-cylinder internal combustion engine, the control method providing for the following: reading a first real value of the mixture ratio via a master lambda sensor associated with a first cylinder group, reading a second real value of the mixture ratio via a slave lambda sensor associated with a second cylinder group, calculating a first amount of fuel to inject into the cylinders of the first cylinder group to track a mixture ratio target value by using the first real value of the mixture ratio as a feedback variable, calculating the mean of the second real value of the mixture ratio in the detection window, calculating a correction value for the amount of fuel to inject based on the difference between a target value and the mean of the second real value of the mixture ratio, and calculating a second amount of fuel to inject into the cylinders of the second cylinder group by applying the correction value to the first amount of fuel to inject into the cylinders of the first cylinder group.
