The second one walks you through the steps to use autotune.
Personally, I wouldn't use somebody elses map. Start with his
safe map that you are currently using, and tune from there. Use the logger on the unit, and have at it... its VERY good at telling you exactly which cell you're in. If you just want to use the autotune to tune it, then change the target A/F in those areas, do some pulls, save the map... download it to the ecu and relog, see how it does. When logging, I like to turn the autotune feature off, it makes it much easier to see the progress you're making.
Personally, I think the autotune is great for see what you need to do, but after its done you HAVE to go back and smooth stuff out. Use the 3d chart, make sure you don't have huge jumps (anything more than about .8ms) between cells, stuff like that.
