Just to be clear, Dynojet is the company that makes the PC-V which, when purchased and installed, can be used without taking your bike to a professional tuner. There are a number of maps that do exist and can be downloaded onto the device. The device is still the piggy back I described and does not directly change your ECU. In this sense, your friend is right. You can buy a PC-V, download the appropriate map, and not put your bike on a Dyno.
A custom map is something different. That typically refers to taking your bike to a tuner and having them develop the appropriate fuel maps based specifically on your bike with whatever modifications you've done to it (new exhaust, high flow air filter, etc.). Direct changes to the ECU, referred to as "reflashing" or "ECU Tuning" is the only way I know of to make direct changes to the bikes fuel maps without an external piggy back device. With the reflash, you don't need to go to a tuner and you don't need a piggy back. However, the person doing the reflash has to have the appropriate maps to put onto your ECU.
I hope that makes sense.
