If you read up and do research, you are fine.
Gotta have proper stuff (knock sensor that oyu know works, wideband, laptop, etc.)
Make small changes, check, etc.
In terms of "light load" portion of the map, there isn't a whole lot you can mess am.
I am on a MAP sensor, so top part of the map (negative pressures) are not going to have a flow much different than OEM, so I am using OEM-ish timing....
I log AFR, divide it by target AFR, then scale the injector open time by that percent.
Iterate, more data, check.
Compared to when my car was "tuned" professionally, my AFRs are way 1) Smoother and B) leaner (in a good way, for economy) than they were when it came off being tuned.
Before, the AFRs were all over the place from cell to cell, now they are pretty damn smooth
