Should I be comparing Lambda or Lambda Adj. to Lambda Commanded in my datalogs for an 07 S2000? All I have been able to find in the forums was Ktuner saying Lambda Adjusted is used for "older platforms".

If you don't have a wideband at a dyno to compare to, stick with the non-adjusted.

I do not have anything to compare it to. I just replaced the stock O2 with a new Denso to hedge my bets against inaccuracy though. Thank you for the answer.

No problem.

I have since added a stand-alone NTK AFM to the car, and I can say with certainty that anyone tuning with the stock sensor should be tuning to LAM.ADJ, not LAM. The standalone meter is dead on the adjusted value, so using unadjusted will end up being much leaner than intended.

Thanks for the follow up. We had only seen the older Civics really need the Adj value.
