Curtis 1236 controller fault

Anyone had any dealings with the Curtis 1236 controller for ac motors, this one runs very erratically as you apply the throttle shudders then goes to full speed. I have checked and changed the throttle pot and supplies / connections are good there are no fault codes displayed. The unit was working before being disconnected from the vehicle ( its in abox with motor with 1 multi plug and 2 terminals for power) so no chance of wiring error. It may have been left disconnected for some time which leads to wonder whether it could have lost its setup parameters if so does anyone have a 1311 programmer?cheers Neil B
