I ended up buying a second hand laptop on ebay solely to have something reliable for tuning and keeping this stuff off the office laptop.
I got a Dell Latitude 7480 with Intel Core i7 processor and 16Gb RAM, probably overkill but I wanted it to last more than a year.
Battery time and a keyboard with back lighting is somethings I really like about this one, most of the time I am in the car flashing or logging its dark outside and its nice to be able to see what buttons I try to push
Cheers,
Alex
