I'm in Adaptronic land with an LC-1 and it just seems like my AFRs are lumpy... Is that the norm? Should I be looking for an issue somewhere? I'm still stock other than the Adap. and LC-1 (and muffler).

I would say my AFRs bounce back and forth +-0.4 with a few larger deviations here and there while idling or cruising steady state on the express-way. Hitting the hammer it seems smoother, but is still a little bumpy.

See attached... Thanks

I see pretty much the same thing with my LC-1, it's nothing to worry about.

 

sounds normal to me. its not FLAWLESS unless you really get in there and perfect the crap out of the map in that region and even then it will bounce around ever so slightly.

why is this in this section and not the Adap section though?

 

Ok, cool... I'll stop obsessing about it.

I put this here thinking it was more of a general tuning/wide band o2 type question.

Its fine, since your injector duty cycle will change from the smallest movements of the throttle, hills, bumps etc.
