Title: A8 W12 Master and Slave? Post by: nbdiy on June 12, 2014, 06:14:58 AM Hello, a good friend has a A8 W12 and wants to install newer injectors with ~5% more flow and asked if it´s possible to change the Injector scale...
I don´t know much about the master and slave system: If I understand it right then the slave only is a extension of the master? So it would only be necessary to change the File in the master-Ecu, or am I wrong? They have different Softwarenumbers, but the Same Ecu-Number... (can post them in few hours) I was able to read out the Master but not the Slave, so it would be much easier if I only have to do the Master, but, if necessary, I would solder them to make both...
