Hi could anyone tell me if you have to programme slabs unit into disco 2 if so can it be done with a nanocom .cos I've not cured my faults yet I've done live test with it and my wheel speeds at both front wheels stay at 1.7 kph while rear wheels go up and down as they should .I then tried nanocom on my mates disco his wheel speeds went up for all 4 wheels as we set off .So my mate said swap slabs units over and see if it makes any difference or would that not be possible .cheers Allan
