I have LS1edit on the way for my 2003 SS. What big differences can I expect from the edit I use on my 2002. I know about using the harness. I think I read somewhere that the power enrichment is different? Anything else?

 

Not much different at all. Maybe electronic throttle control (ETC), but not much else. Same fuel and timing tables. Same layout in just about every tab.

 

Is 2002 when GM started using the Fuel Ratio vs RPM spark modifier table?
