tuning questions, tuner cat - newbie

Okay looking at some tables I dont fully understand alot of the tables

are there any write ups that do into detail the fuel equasion that the LT1 uses for fueling. How exactly the Block Learn Cells work, etc etc??

individual cylinder trim - was this to fine tune injector differences at the factor? what if i've removed all the injectors and moved them all around? just set them all to 1.00 so no change???

%Change to AFR vs RPM at WOT - this is commonly refered to PE correct?
are my bone stock values in line with what others would see?? or are these also fine tuned to each engine at the factory? adjusting the VE tables would also make this PE tables wrong correct?


400 4.7
800 4.7
1200 -0.8
1600 -0.8
2000 0.8
2400 0.8
2800 3.1
3200 0.0
3600 1.6
4000 0.8
4400 2.3
4800 8.6
5200 9.8
5600 6.6
6000 2.7
6400 2.7
6800 2.7

under ECM constants : MAP threshold to enable WOT

the stock value is 15KPA, is this correct? 15KPA would be a very big vacuum, like a high rpm decel, 0% TPS what this this value refer to, or am I understanding it wrong

There's also %TPS threshold for WOT vs RPM cool, hot

my hot table is all '0's
what does the computer determin as cool and hot

i have more questions. i'll ask more later.

thanks
