hi ignition maps i have , spark advance part throttle , spark advance correction , spark advance wide open throttle , is there some were i can decode all these, so i no which one i really need to change

If you can log the actual final spark advance while running, you can correlate this to the maps you have available and this will usually guide you in seeing which tables the ECU is referencing. For your example the WOT and part throttle maps sound self explanatory and it's just how the correction integrates that might need some understanding. In most cases you would make your changes in the main maps and often the correction maps can be left untouched.
