eCtune is the latest ROM Editor available for Hondas. It is written by Calvin Baank and has an exhaustive list of features.

eCtune has very structure licensing. It is important to note that eCtune tunes will only work when run off the Ostrich. This means a separate Ostrich must be present in each car you tune with eCtune. (For all you CROME guys, there is no more burning chips and walking away)

At the end of the day, if you want to drive 5 cars at the same time, you will need 5 Ostrii.
