TX is showing what the software is sending. It's the RX values that need to be correct, so the software then shows "good idle". Have you checked the connection from the Diagnostic Port to the ECU, especially the left footwell connections ?
Once it actually connects properly, the TX will show a steady stream. Then when you click the various things like Read Faults or Get Values, the TX will change to a few transmit bytes for each command.
Do you mean the EAS ecu under the left seat? To be honest I am not sure what to look out for other than a really obvious broken cable or unplugged connector. Mine is LHD if it makes a difference. The EAS has been causing nothing but trouble over the last couple of years. Otherwise the car is more or less perfect with only 53 thousand km since new.
