I have an 03 A4 1.8T 5sp. ECU 8E0909518AF SC 0016701. I've been trying to find an XDF but so far none I've tried work well. All the tables do not line up except for several are kinda close but not really. I've also tried using AK files as I heard those should work with no luck. I'm a total noob and have no idea how to make or edit XDF. All I need is basic fuel, boost and timing controls. I'd also like to code out Cat and SAI.

I also had some issues reading my ECU. I tired using all memory layouts and baud rates, all failed until I set baud to unspecified. From what I understand 800BT or BB should have worked at 10400 baud. As far as I can tell my check sums are good. Any help to point me in the right direction would be appreciated.
