Ok i know there is a tutorial for SD tuning VE using the autotune feature of EFILive (which absolutely kicks azz) ,
but that required a WB O2 sensor, which I don't have yet. And when I do get it, I'll then have to find somewhere to get the O2 bung welded onto the exhaust.
So, in the meantime, how about tuning the VE in SD mode, using the LTFT's from the car's narrow band O2 sensors, to get me going in SD mode until I can get the WB ??
I found a write-up using HP tuners on the LS1tech forums, but I figure as powerful as EFILive is, there might be an easise way to set up to do this?

Since there is already a map in the scan tool for LTFT %, in MAP kPa vs. RPM, can you scan LTFT values in %, then copy / paste those to the VE table, which is also in MAP kPa vs. RPM, to correct the VE to bring the LTFT's down to zero? Am I a total idiot ?
please help me out
