Reaching out for some help on tuning

[ToXshoX]

Have a look at post #1 of the Calc.VET thread (sticked in Gen III section), this shows which pids to log.

RR sbould show up same as LS1B in scantool.

Switchable tunes is for GM Diesel.

No worries, we'll get back on track.

What is the link to that Calc.VET post I have https://forum.efilive.com/showthread...-single-log%29

The roadrunner will be able to select once connected usb?

I don't know if I'm making this harder than it is but It seems like a huge about of information to know and understand and I get overwhelmed. Since I never seen anyone tune before and the most i've ever really messed with is turning off sensors that trigger codes and changing speedo and e fan setups. I'm a bit cautious and unsure of myself. What is the black box suppose to do in a nutshell. I think my lack of understanding some of the forums is because i've never tuned fuel injection before. Many carbs i've done with the help of wideband gauges. But i honestly don't know and i've never been told what really is needed to be changed to make the engine run richer or leaner.

I read the steps in setting up the black box and even that one forum post on calc.vet but I don't know what it's doing or going to be doing.
