The LCD uses a 1Gb card only. It'll hold lots of data.
The LCD will create up to 35 data files, then poops out. Clean off the data files regularly.
You can store as many maps as you want on the card and load them into the PC V when you wish.
You need to get the "Display Manager" (free download) for downloading data off the card. I change the data rate to 1/10 second in order to see quick changing stuff.
Throw it into Excel and go crazy.
I suggest logging your TPS and RPM for a whole day in the hills. It'll be surprising how little WOT you will use compared to how much you think you are taping the throttle.
I don't think you can easily tap into DET stuff - you have a dash display that gives immediate feedback if you have issues.
I typically tap into the coolant temp sensor or the air temp sensor and the EGT sensor. Plus, the PC V monitors pulsewidth, % utilization of the injectors, and a bunch of other stuff.
Just make sure you do your tuning and data stuff before everyone else gets up - it's easy to burn an hour or two "playing" but you don't really need to tune on the fly. If you start having an issue, hit the "Record" button (not a button, just tap the LCD screen and hit the upper left box that comes up and you are recording.) Collect data and look at it later. You can also use a toggle switch to go between pre-loaded maps - switch to a zero map if issues come up and keep riding.
