Kanzus,

Here is a good web site that explains what you can do in developer mode in the Star DAS. Read carefully as it looks like you wouldn't want to be sitting in the car while using this mode! In this mode it looks like you can make your own selections about engine and gear ratios if the chassis you are working on did not come with the engine you are installing. I believe to use this approach you would need a new ECU or you will need to unlock the one you have. Beckman Technologies can unlock your ECU for $250 USD.
