Hi all, this is my first post here. Be gentle! Two weeks ago I bought a 2017 Leon Cupra ST 300 4Drive DSG (that's a mouthful!), and I'm generally very happy with the car. Though, for something with 300 odd Hp I did imagine it would have a little more punch than it does. I've managed to acquire an ABT AEC which was fitted to an older Cupra 280 with DSG, and the chap claims the box gives an extra 58hp / 80nm over stock. His car had the CJXA revision of the EA888 Gen 3. Mine is CJXC, albeit the car has 4Drive. As far as I can tell, the ECUs are the same across these two engines, only the tune is different; indeed, if my research is correct, the engines are physically identical. Does anybody have any experience with switching these piggy back ECUs across vehicles? I've contacted ABT, both in German and English (I'm located in Germany), but I'm being completely ignored (par for the course with ABT it seems). Appreciate any and all assistance, thanks in advance!
