Yeah mate that's what I mean the map is erratic in terms of its cold start characteristics, might be fine one day. next day starts playing up. This is a known issue with the map mate I would think. Bluefin won't play any part in it it is the base map itself that has the cold start issue. I don't know how to go about fixing it though...some have changed the map with a custom one, think there has been situations of different spark plugs used but not sure.
