Just a thought here but my buddy has some scanner software for his WRX that was free/open source type stuff and it's got a really cool feature. Instead of having to push space to start/stop the scans like HPTuners (and I think DHP?) then having to save each scan out, he can simply push his defroster button on the dash and it will start/stop/save the scan automatically. Means you can just plug the system in and go off logging/scanning.
