Hi everyone , just want to know if this is normal , when i select O2S11 and O2S21 voltages along with the short term fuel trims that come with these pids > if i am connected to the pcm i get no voltages or feul trim % in the data table but if i save the log and play it back there they are , the heated HO2S11 and HO2S21 are there either way , by the way what is the difference between heated and not , i noticed it did this on my friends 98 5.7 vortec also , my truck is a 2000 silverado 4.8l , thank you in advance , Eric
