How has he tried to name and shame anybody???!!! Sounds as though he's fitted the system himself, wants have a go at doing some mapping and is after some advice....what's wrong with that?? A base map is never going to have the car running perfect, doesn't sound like jamsport has had the car in for mapping so no fault of theirs, although i agree it would be easier to get the car to them as they've mapped loads on gotech!
