Hey all,
I am tuning my 2008 trailblazer wit a 4.2 and the e67 ecm
i set all othe o2 readyness to 400deg and have disabled ltfts in the tune. I unplugged the front o2 and replaced with wideband.
After its all warmed up i see it throws the o2 code because its not plugged in and the arf/eq commanded sit at 13.98/0.952.
Is this normal? I usually tune my gen 3 2002 trans am race car but i have a bung so i dont replace the front o2.
I figure its fine since im just doing maf and sd error based on what the computer commands and the actual but was still odd.
just wanted to make sure its not going into some limp mode and causing errors
Thanks!
