Smith will give you any map that he has for free. Apparently he has quite a few for alot of common exhausts. The ecu editor maps Smith has are ones he has made or ones sent to him by members that have had there bike tuned with the ecu editor. You also have to consider that power commander base maps are just that, a base line, to get you close. For example, you could use a power commander base map for a stock gen2 with a full yoshimura exhaust, and actually be running a full Muzzy. It's possible that the bike will run as good or better with a base map for another system. That's not always the case, but it does happen. A bike will run fine without any tune at all with a full exhaust, not too lean or damaging to the engine. A bike will run better with a base map, and at it's best when properly dyno tuned by a competent operator.
If you could read the fuel table from a power commander you could write that map(or one very similiar)with the ecu editor software yourself, but that's not recommended unless you completely understand what you're doing, as you could make a serious costly mistake.
Basically if you buy the ecu editor ask Smith if he has a map for what you have. Also two identical make and model bikes with the same mods will not nesacarily have an identical fuel map when dyno tuned. Running a power commander base map or ecu map from Smith will get you close, but a dyno tune is the only way to make your bike perform at it's full potential.
