Guys today I went for a highway ride and had the chance to run fast for a couple of minutes without being interrupted by traffic. I kept my android phone running ecmdroid in the handlebar mount so I was observing the sensors behaviour while running.
I realized that while in closed loop the o2 voltage keeps changing from a high value to a low value, all the time. As far as I understand this is OK, it is how it must behave. However, when it entered open loop, I saw voltage was always around 0.75v. I didnt go to WOT anytime, I just kept it running from 4000 to 5500rpm with 100-140 tps load which is definetely open loop, from 140 to 180kmh for 10km so I made lots of observations on the ecmdroid.
O2 voltage is very stable and always around 0.75v. Maybe lowest reading was 0.71 and maximum 0.77v, but it doesnt "cycle" down and up how it does when in closed loop.
My question: is this normal behavior? If it is, is 0.75v adequate to the open loop (not wot) region of the map? My open loop map is basically stock, so I'm not really worried.
