When he ran the codes after installation, sure enough 27B7 electric fuel pump came up
A friend of mine has a '10 GSA and his controller failed too. But his bike acted like it was running out of fuel and finally just died - he couldn't ride it back and had to trailer it home. He had a 911 and it also came up with the fuel pump error.
He took it to the dealership and they replaced the controller stating that his bike didn't have the new updated model. His old controller had corrosion and was pitted on the board. Supposedly the new controllers have sealed boards... that's all the upgrade was about.
Maybe I'll just open mine up and look to see if mine is sealed... '11 GSA.
