Hello, I brought my cupra R ABT a few months back now and absolutely loved it. I normally remap all my cars with revo but thought as the ABT kit didn’t effect the warranty it was a no brainier. I brought he car as a daily driver with the intention of maybe doing a couple of track days a year. Went on my first track day with the car at the end of September and thought it was great, handled really well, stopped really well I just noticed that up the main straight my mates stage 1 VRS was staying with me. And made me think well I should have at least an extra 60 bhp than him so should be pulling away. I went away and thought I’d get the car dynoed to see what it was actually putting out. I’ve taken the car to two places and it put out between 306-309 at both. Obviously well down on what’s claimed. (I only run it on a min of 98ron). I complained to both ABT and seat UK, they looked at my car and said that the kit was fitted properly and when hooked up to the diagnostic equipment was told it was functioning fine. It was explained to me that the ABT kit is standalone from The cars ECU and if it thinks it’s too hot it will cut the power to stock. It is a lot more sensitive than the cars heat sensor. I was told that the car would only show putting out the claimed power if it was put on ABTs rolling road in Germany because it’s temperature controlled. This is why after around half a lap the kit would stop working and car would only put out stock power. So there’s no way of actually seeing what the kit is doing or how much of an increase it actually gives. It obviously does something because you can tell when it’s working and when it’s not. Long story short seat have said they will take the kit off my car and pay for me to have it mapped else where (probably revo) when they release the software. Just wanted to make people aware in case they had similar issues thoughts.
