I found this on aother forum:

Real tuning requires map manipulation in certain areas of the table. In adjusting a map it is necessary to lower or raise certain areas of the map, and linear manipulation does not allow this. Since much of our switching is patent pending, it is no wonder that others would explore these options. We felt that the Lemmiwinks software was not powerful enough to charge the consumer for, but it may be useful and fun for the consumer as Freeware. We will be posting a technical write up of the program with some explanations of its abilities as soon as possible. We should add that we do not consider this program or any others like it to be an advanced tuning kit.
Basically, it won't adjust enough to make your car super fast. I wouldn't want to DIY my tuning, because I know my car would blow up as a result. I think ECU mapping should be left to the pros, thats why I recommend real Revo.
