[Link G4+ skyline GTS/STR problem]

This suggests you have a "backfeed".  Usually this is caused by something that is wired to an aux output that is connected to a power supply that is live all the time.  Anything that is connected to an aux output must be powered from an ignition switched source.  I would first check anything which may have been added to the wiring such as a boost solenoid.  

yes it may be possible because I have a weak power supply. But I don't understand why the factory ecu works well and link g4 does not work properly, the fuel pump control module stops working, I have the tps wire with current and link g4 is constantly on even with the key off. none of this happens with the factory ecu.
