I have one problem which bothers me for a year or more.When I connect tunerstudio via usb or bt everything is ok until I start the engine.After that tunerstudio disconnect with lap/mobile,in some cases engine will shut down or misfire until I disconect USB cable. When I changed edis coil to tfsi coil few days ago my car started to misfire while driving. I have noticed that my rpm gauge oscilates,so I changed my crank sensor (HALL ) for new one,but the problem remains,also checked voltage on all sensors,coils and inj. Any thoughts about this?
My board is 0.4.3 working on 6cyl semi-seq mode.
