Anybody have a wideband O2 they want to part with? Preferably a good used AEM one, just for money reasons, but let me know what you have. I have one of the cheap autometer narrow-band air/fuel gauges but want to upgrade to a wideband. how accurate are those narrowband ones? can you trust them to tell you CLOSE the “truth”? i know alot of times they bounce around between rich and lean, but i just put in a new o2 sensor and it stays pretty steady about 1-2 o’clock on the gauge while i’m under power. i understand the 0-5V is definitely better (because of the higher 0-5V resolution), but wanted to know how much i can trust the 0-1V narrowband. I know i’ve asked this before, but money is a bit tight and i can’t afford the whole obd1 swap and dyno tuning right now. it runs like shit on the 450’s and its definitely running pig rich (it smells THAT bad). i wanted to just put the stock si injectors back in so i can drive it for now and keep the boost extremely low (5psi-ish). i would think the stock tune with an fmu and extra inline fuel pump would be anough to keep it safe? BUT I DO WANT A WIDEBAND TO KEEP AN EYE ON IT… ---

can’t trust a narrowband to tune boosted setups. they only read a narrow range very close to stoich and you want to tune richer than that under load ---

Do you just want one to tune with, or to run full time? I’ve got a standalone Innovate LM-1 to tune with (provided your tuning program can disable closed loop operation) then run the stock narrowband once fully tuned. ---

I want to keep one in there full time…all i have is a narrowband and i dont really trust it. i believe stock si injectors (280’s?) and low boost should prob be ok to run, but i want some piece of mind that its really not running lean ---
