As above really I have a Ls1 with cable throttle, red and blue connector PCM with a 2 bar SD tune, which was tuned using my Hp tuners kit. Over the winter I have carried out a large engine rework and now has different cam and injectors. For speed really as i plan to go away in the car soon and the engine isn't even in the car yet I was going to get the local specialist to map my car but he only has efi live. He could use my hp tuners I know but I think he would be more comfortable using what he knows.
The question is, if he uses his efi live to tune my car, as a base map, can I then continue to carry on where he left off with the tune he did but with my Hp tuners kit. Or is it locked to his efi live and would have to wipe the lot to start again. Thanks
