Sorry that nobody has replied to you despite several days since you posted. So far as I am aware nobody is doing ISF calibration in Ireland - south or north. Gordon (www.convergent-av.co.uk) has been trying to put together an Ireland tour and having spoken to him about it, the problem seems to be the huge distances (or rather the time to cover the miles) between customers. I am a retired rally driver so have a fair idea about your roads!
