Closed loop with an AFR target sure would be nice....
Closed loop will be nice, but won’t it require either (a) unleaded fuel or (b) an O2 sensor that can handle lead? My O2 sensor gave up in about 3 hours.

We've seen widely varied WB sensor life on 100LL- between about 2 and 450 hours. I have no idea why the huge variance.

The closed loop feature is mainly targeted for engines running unleaded fuels, either Mogas or the 100UL we hope is just around the corner.

Not around the shop most of the day. Will try to answer phone messages and email later today or on the weekend.
