F1 Code after Gman controller

Fitted new vance and hines pipes, K&N plus Gman controller.  Im getting an F1 error message.  I plugged the o2 sensor and fitted an eliminator to the oxygen sensor port, but still F1 code.

Any ideas, Gman are sending me an alternative eliminator as i noticed there are 4 wires and the eliminator only picks up 2 out of the 4, the guys i purchased the eliminator from suggest you only need to block off the two cables.

Bike rides great, responsive and really nice acceleration, just nervous im doing damage by riding, ligh only comes on after riding for about 5 mins, im pretty certain its because of the oxygen sensor, any way to check?

Any advice much appreciated?

Ill answer my own question as i found the solution.  

To stop the F1 you need to cut the appropriate cable in the ECU, while daunting seems to have done the trick and all working ok.

Gmann controller seems to make a huge difference to responsiveness of the throttle and general control and acceleration
