Only at full throttle, and , even then momentarily, the mixture would drop
to Lamda = 0.85. Hardly any differnece between booster plug and OE.
My conclusion : The ECU is much smarter then most people think...
That's just the point. Once the ECU with stock O2 sensor goes closed loop lambda will equal 1. That's why I'm going to let the LC-1 drive the Motronic Then I can adjust closed loop lambda.

Air temp modifiers affect open loop, including making a favorable change in afr when e10 fuel is used. E10 is a leaner mixture open loop (closed loop lambda is still 1!) but booster and iice richen open loop and therefore compensate for e10
