I think Ellis runs the WB Commander, and I posted at the other thread.

No Ellis hasn't posted yet. He'll probably have some good information for me as always.

I'm just curious about the calibration, and about the warming up period. Also I need to get my laptop fixed so I can download data from my 1/4 mile runs.

I like the feature of recording so you can check your A/F against RPM. That way you can monitor where the lean/rich area's are more accurately. There is no way to monitor your A/F gauge while your running down the track or even on the street for that matter.

I got the wideband commander working I think!! The car idles right around 13.0 when the car is cold and still trying to warm itself up, then it drops to around 14.7 like Robert said. And when I rev the engine the gauge sways to the left (rich) and then after I let off the gas the gauge sways to the lean side. But it sways way lean..........like in the 16.0-17.0 area.

Imagine the car is idoling at around 14.7 then as I stab the throttle quickly (step on and immediately let off) the needle moves to around 13.0ish and then goes way over to 16.5ish before settling back to 14.7.

Does that sound about right???

No I haven't. Today was too wet. Every time I went WOT the car slid sideways. I need to take it to the highway on a dry day.

What should the A/F be roughly during a naturally aspirated WOT run?
