[chipcar cordoba]

Hi i have a renaul megane ecu sirius 34 s118301104 8200124318 , i read other post but it is not clear to me, I know that between lines 4000 and 7fff you have to change some digits and the two previous ones to FF FF FF FF and put emulator.My question is the following one must cut some pin or do something else?

Thanks
