Running Lean Just got my ls1 Chevy S-10 running and trying out my Efilive software. Went for a drive on the freeway going downhill and noticed that my LC-1 wideband was showing 20.0. I also noticed that the spark, long term fuel trims and injector duty cycle was all at zero. Is that normal? Would appreciate any input.

Most likely DFCO kicking in. Basically DFCO leans out the car on decel and cuts spark to make the transition less noticable.
