   If you have some way of reading the air fuel ration and some way of loading the engine for extended periods and have a SigCon 2 (or3) fitted as well to stop the standard ECU seeing the boost then its very easy to map. Its just a bank of screws that adjust and they give an in proportion fuelling to boost over the screws given rev range. You load the engine up then adjust the screw to give the fuelling your after.

   i have no sigcon just check valved the standerd map sensor so it can only read vac in the manual it says just set when you want the injector to fire then set how much fuel you want fireing in ive got afr gauge.so best thing to do would be sit in the car set it to vac/boost change over point then ajust fueling to each rpm so the afr gauge stays in the green

   Ideally of your doing it on the road you will want to find a nice long strait hill to map it on. The problem you will get with out the SigCon 2 (or3) is that the standard ECU will see the extra fuel and start leaning out the standard injectors. You just end up fighting with the standard ECU.

   it can be done if you got a AFR but if not you will be guessing

   it can be done but is not the easiest and isnt 100% reliale, as ax sais.. in ideal conditions you need a long straight hill....how many ppl have one?
   
   i have a sigcon 3 fr sale if interested mate, letting it go really cheap, worth a look if you value your engine
