Hey guys Im pretty new here. I've been reading into o2 sensor switching points being affected by having long tube headers. I was wondering if for 1.) I am even asking a 'sane' question and for 2.) What kind of condition would this cause? (false rich or lean condtion)
Please help me out, Thanks!
1. There's nothing wrong with your question,
the O2's switching makes a difference on AFR.
2. I increased the values in the idle areas to richen the idle
and decreased the WOT areas to lean out a bit of over fueling.
I ended up with a flatline of 500.00
Keep in mind my LTFT's are -5% and my MAF has been rescaled.
Well I just swapped an 05 LQ4 into a 86 monte. I never knew what stock trims were and went straight to head/cam long tubes. It now shows that im -18% LTFT pretty much anywhere. I was just wondering if my o2 sensors location where giving me a false reading.
Any input in appreciated, thanks.
