I am tuning a Porsche 911 with M48 and wide band lambda. How do I determine the Lambda trim value and where can it be found (what table? or key). I have been tuning with the lambda control off but want to switch it back on. Also, should I turn off acceleration enrichment when tuning? I have been performing the fine tuning during small drives around town. The majority of the tuning was performed on a dyno.
