Hi guys basically ive put a bwj lump into my dsg leon but didnt get the ecu from the cupra, having a bit of trouble during idle car seems to be dumping fuel and running very rich, was wondering wether this would be due to it not having the cupra ecu.
When mapper tried adjusting fueling seemed like ecu didn't want to play ball.
Any help would be amazing.
