As part of the continuous improvement of your 208 Rally4, a new alternator management is available. This new option called "LIN", active in STAGE mode only, stops the alternator’s charge during acceleration phases to provide additional power, then restores the charge during braking phases ensuring an optimal battery charge level. In ROAD mode the alternator management is classic.

In order to use this system you will need to upgrade your ECU & install the relevant loom. 

Part A: 904902508A x 1 - Alternator LIN Loom

Connect the LIN Loom to the free connector <LIN> located in the front right leg then to the free female alternator connector.
