I have reset the ECU, knock adaption, vano adaption, etc. through BT cable this weekend and put the car back on map 3. It felt great at first. But at the middle of the drive, I can feel the car become less responsive. Don't know what happened, but it feels like there are a lot more lag at sub-3k rpm and the engine lacks top end power. Don't think it is possible, but can the ECU adaption actually make the car slower over time?
I couldn't find any code with the BT cable. But I have a data logging cable which I didn't install with the JB3 at first. Think it is worth it to open up the ECU again and check everything is connected alright and attach the data logging cable along the way? Could it be any other problem with the car? Mine is a MY09, automatic transmission.

It's easy to spot if everything is working as it should be from a JB3 datalog. So do that and send it in to BMS.
