Unichip actually make a big point that trying to tune every single cell is probably a wast of time. Tune a few specific load/RPM site, have the map autofill between those sites and then check for areas (torque dip) that need specific attention.
As for additional sensors it would be nice if they were all available and more could be wired in but it's probably not worth it. I'm happy to use a separate OBDII reader that can give me even more data like short/long term knock correction the ECU may be doing hiding issues with your tune.

Your happy because you have not done it any other way, both Tuner Studio and HP Tuners are free to download. Grab HP Tuners I will send you a a few log files (They are small under 5mb) and you can see all the data you can look at logging.
Roughing in fields is a great way but think about this, are you familiar with how using boost works? You have a 12.5:1 compression motor way above the factory level of compression for adding boost and for one important reason, knock when boosting destroys a motor. They stay between 8-9:1 for a reason its safer.
Now you can do it obviously but doing it with E85 is safer and gives better results anyway with its ability to cool the intake charge and resist knock.
If you set everything to 0 and boost the motor stock the factory ECU catching you before you hurt something is a BIG gamble. Jack even mentions pulling a lot of spark and then working your way back up which I am sure you heard too.
I wish you luck, definitely error on the side of caution while doing it. I hope all turns out well.
But however back to the E85 files and finding out exactly what the legality issue is preventing their release and what we can do to over come it as customers.
Only Jack can answer this for us.
