This. Software. Is. Awesome.
I'm working with a bone stock D16Y8 for now. I tried starting fresh with my own basemap built from P28 settings (figured it was close enough). I had to add about 25% to the whole low cam map to get short term fuel trims down to zero. At that point I figured my basemap wasn't off to a good start, so I would try someone else's. The file terry.ncl seems way better right from the start then my basemap.
I was hoping to check out a few other Y8 stock maps to compare - would anyone be willing to share?? There is another Y8 NA map on there, but the fuel map looks way different so I didn't want to try that one.
Also, the repository on the hrtuning website seems to be down (http 500 error - webpage cannot be displayed). Works fine in Neptune though, so no big deal, just thought I would mention it.
