ok probably dumb question got everything set up to scan lambda for now I have commanded lambda at 1.0 across the board. I am beginning to try and tune ve and I think I can use the pre loaded lambda chart as long as my commanded stays at 1.0. what I am running into and would like to learn or figure out is the preloaded lambda chart will say .98 at idle and my commanded lambda I set up is reading 1.02. I know it is simple because its very close across the board if eq says 1.03 my lambda error will say .97 I know its simple and I don't like asking but any help is appreciated
