To the track guys out there , i was wondering how they
set there mixtures on the track with there MB's? you guys running O2 sensors or EHA on or off?

I know with the old CIS porsches , they disconnect the O2
run a few laps to warm up the engine and richen the mixture
, then set it back to drive home with.

or is there racing O2 sensors and EHA?

thanks
Dave
