Dyno vs Scan Tool
Dyno vs Scan Tool
We dyno my 86 vette today and discovered my Diacom GM PLus was showing a rich condition yet the dyno was showing a slight lean condition from idle to about 3000 rpms. The o2 sensor is a brand new bosh. Is there something I can adjust to get the ECM to reflect what the dyno is seeing?

A switching O2 just tells you if your rich or lean, that's all it can reliably do.
If you want a O2 sensor to monitor AFR then you need a WB.
