Not sure they would be much use to you as you also need to know all the other ECU set up parameters. Even then the state of modification has a massive effect on the required settings.
Unless you have 2 identical cars (and I mean basically factory standard in every way) then a map is not transferable between cars.
The default map (when reset) is as good a starting point as any.

I have set the car up by modifying the default map running 11.1 afr under full boost and a maximun of 26 degrees advance, this works fine most of the time and the car performs quite well but I am in Sydney Australia and fuel over here, the 98 octane is not allways what it is supposed to be actually our lead free super 96 is more reliable, because i sometimes i get 80 on the knock and other times when the fuel is good 6 on the knock. I basically just wanted to look at someone elses maps to compare and see how they were setup to make sure i am heading in the right direction.

You are never going to get a map to suit an unstable fuel quality, for sure a knock of 80 is causing damage !! Apexi recommend a maximum of 40 but personally I consider that is still way too much.
What model do you have ? the Sti will normally run more advance than our UK/Euro spec cars, if your spec is the same as a JDM WRX then 26 degrees could be 'pushing it' a bit !
AFR sounds safe enough.

Basically my car is a MY99 WRX not STI with standard injectors 440 cc running 400 kpa/ 57 psi at idle with no vacuum connected should be flowing around 550cc, Walbro 255 litre per hour fuel pump, VF34 Turbo, front mount Hybrid intercooler, 80 mm turbo back exhaust bell mouth from the turbo back, Hitech Exhaust no cat, at the moment 1 bar boost but i normally run 1.2 bar if the fuel is good. Running 95% injector trim, Uego sensor for AFR, i am getting 90 % injector duty under full boost at 6000 rpm might need 550 cc injectors, fuel pressure is 500 kpa at 1 bar boost at 6000 rpm
