I?ve seen tuners put widebands at the end of tailpipes for tuning and people shove them into stock cats or bango them next to o2s1 narrow bands. I?ve read mixed reviews where people say it?ll only change it by .1-.2 stoich lean going after cats in normal cruise and accel if that but will be accurate at WOT.. other people saying it?ll make everything be in accurate..
I really don?t have room to install it next to my narrowband on my long tube collectors and I really really don?t wanna remove the headers. My rear 02 sensors are just taking up space.
Shoot me straight, can a person really put a wideband after a dinky high flow cat and have correct readings?
