logging it of course is best. You want the open loop numbers, that is when all the sensors are doing their thing and you are at WOT wide open throttle. The closed loop stuff will fluctuate but always kinda read like what you have gotten already. Closed loop is just cruising or idling. You want your open loop numbers to be around 13:1 for best performance. (disclaimer) I was advised this by somebody but please have your car tuned by a professional for safety of the motor and performance. Pedro can probably help or FVD. Giac if you can get them to get you on their dyno. I use a wideband 02 sensor.
