Specifically, I'm used to tuning countless 2003, 2004, and 2005 SRT4 Neons regularly using the scanner to log. It has never been really great to begin with on 4.2.12. It is always buggy and I need to disconnect, reconnect, sometimes even unplug usb then replug to get pids working properly. Such as Map readings at koeo read 17. Fixed by reconnecting. And slow, fixed by reconnecting. Now, with the update, things work fine on Chargers and Challengers for example. But, for Neons, I experience slow scanning no matter what I do to try to remedy things. The data is not useful at all at this speed. Sometimes on connect it doesn't display and data at all. Scanning Neons is essentially broken I feel. I have resorted back to the 4.2.12 software to be able to work at all. Just something to add to the list of items to fix in your next update kindly and hopefully.
