ABT AEC - can you switch between vehicles?

    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!

    Plug it in and see if it works

    it just works by messing with signals from different sensors so i would imagine it will work no problem

    I've heard conflicting reports; ABT say that the device somehow connects to the CAN bus of the car, but a guy who teared one down in Australia a while back claims that they're more basic in their operation than a JB4. Yet somebody else has mentioned that they're somehow tied to the car in which they're originally installed - guess we'll see

    Where does it plug into if its just an engine harness with plugs it will just be like any tuning box, if its obd port may be tied to a cars ecu

    Thanks for your responses mate... Not OBD, just harness as far as I can see. You're saying it's not tied to the cars ECU if the OBD port isn't involved? I'm a relative newbie with piggy-back tuning, have only done remaps until now

    Apparently they are tied to the cars VIN they were initially installed on but you could try it and see ?!?!?

    re contacting ABT they generally ignore any contact with anything that may be ‘awkward’ for them.

    Your best bet would be to contact a local reseller who may be able to help you or give you more info on it and if it’s possible.
    Richter are the main reseller in the UK I think, don’t know about Germany however.

    Thanks for your reply

    I've heard the 'tied to VIN' rumour myself, not sure if it's true though. I've not received the unit yet, will give it a try once it arrives.

    The reseller route is a good idea, I know there are some ABT resellers in my area. Will see what I can find out.

    Yeah it will work will just mess with the signals, sounds like a pretty straightforward tuning box, i would have no reservations about fitting it.

    more importantly why the hell have you not got it on already :eek:

    It's in the post on its way to me still! I'll report back once it arrives and I've had a chance to plug it in and see if it works

    I know when I ordered my R ST and it arrived in the UK the dealer claimed they had to send some logs to Richter who then programmed the module for the car, sent it to Seat, who then install it.
    Of course who knows how much of that is actually BS and Richter just send a generic unit , but it sounds good to the customer buying it.

    After researching the ABT box on the net for quite a while, read all the years old stuff like the Aussie bloke who did a tear down, George from BMS saying it wasn’t CAN-bus otherwise it wouldn’t need certain sensors. I have definitely concluded it must have a CAN-bus connection. It wouldn’t be able to do what it does protection/performance wise based on charge air temps, oil temps, altitude, coolant, intake temps etc etc of couldn’t get all this info if it was just intercepting a few sensors. And if it wasn’t why would it need the very expensive Bosch CAN-bus wiring harness ?

    Found this link very useful in what it does

    Thanks for the link @Slickric21, very informative. Some of the best info I've read yet.

    I'm also inclined to think it's more than just an interceptor device. Luckily I didn't pay much for it, and the guy I got it from lives in the same state as I do, and will have had access to exactly the same fuel as I do, will have had very similar weather to me, similar altitude etc etc. So I'm hoping that since the engine the unit was installed on is effectively the same, it should work; so long as its not somehow locked to the original car. Time will tell!

    I should receive the unit next week.

    An update for those interested: I've since found some content which suggests very strongly that the ABT AECs are NOT locked to the ECU of the first install, at least not those from around 2015-2016. I'm getting more sure that this is going to work. Hurry up DHL!

    when I was buying mine in the dealership there literally a guy there with a laptop plugged into OBD port, he was getting the relative info for the ABT upgrade, not sure why any module can't work with any ECU but there's obviously something in it...

    Could potentially have been something as simple as the ECU ID or revision. I'm sure they record all such IDs for warranty and logging purposes. We'll have an answer once the often terrible German post delivers the goods!
