do you also have an egt and other sensors? it makes life a lot easier if you're doing it yourself via the laptop
its not too bad to do - do you already have a baseline map already, or no?
you can do a simple one that gets you off and running within 30 mins.. the more detailed ones will take a couple of hours at a minimum for across the band efficency !
And, if memory serves, rallispec was doing Link ECU set ups at one point.. so you may want to call them!
