......not good i know,but this is the first time its peaked that high;could it be that the engine wasn't warmed up enough and the wastegate was sticking, or is it more than that? My egt was still pretty cool, but I'm trying to figure out if there is a peak hold on the O2 voltage,or do you just have to watch it?

mmine does this in the cooler weather. Actually it seems to me that if i set it at .8 i usually get a peak somewhere around .85 anyways..since this is only a peak reading i thjink its normal/

Mine will go from a 0.8 setting up to 0.83. It only happens in cold weather and as soon as it goes over .8 it stabilizes and comes back down throughout the throttle application. I believe/hope this is normal.
