I didnt say he had not done his job Bill - the fact is the guy wants access to his map to develop it - original mapper is v happy with results and not looking to do more. The customer now wants to develop it further. To do this it would be much cheaper for them to continue on a map that already runs the car etc instead of paying the time for a new mapper to start from the beginning again.
The problem is old mapper wont give access - and by the sound of this it was not agreed before the job was done. I can see both sides but as Euan is asking from the friends side I would say look through the invoice etc and see if you can take it further - I believe it to be a grey area and doubt V much he will get anywhere and would be better off trying convincing the old mapper its in both their interests.
I think Marks attitude is spot on to developement and customer service.
