After following all the steps i was able to dump my ecu files to my computer however there's no definition file for my ecuid AM605. I tried AM603 & AM604 but to no avail. Anything else I should try I'm pretty new to all this so don't crucify me.

It won't work, you need to develop a new definition file for this ROM.

How would I go about doing so ?
