Vf e38 fuel pump out put

Hi guys, so Im fitting a after market fuel system to a vf r8 and bypass the fuel pump control module , I've got a seperate fuel pump relay and trying trigger from pin50 on j1 with a + output to relay , but the ECM doesn't trigger the relay I've adjust the fuel pump settings in the tune file hopefully correctly

any luck with the fix? I too am having problems. pin 50 randomly stopped sending 12v to the relay. it did work before. I hope im right that pin 50 sends 12v+ to the relay, not ground like my 0411 does on my other project. any ideas
