73660, wideband reading questions...lean @ idle...
Posted by tim97rs, Apr-28-04 03:58 AM
okay, i have the innovate LM-1 wideband. i just did the first pactice reading today. what i noticed is i am running rich(i knew this tho). BUT heres my quandry: at idle im getting a wideband reading of about 15.5-ish. My FP is 34psi, i have the SFMU with the dark spring and small disc, accell 40's, and an SAFC.
should i be adjusting my idle FP for a more stoich reading of around 14.7, or is that "leaner" 15.5-ish reading normal for idle?
i will have more questions once i get the logging figured ouT.

If your O2 voltage cycles at idle, it's right where the ecu wants it, and as such, right where it should be. You'll probably see ~15:1 at idle and low load cruise.

Mine (Tech Edge) bounces around between 13 and 15 at idle.

Cool. i was worried about around town driving(low load)seeing that number. its 15.2 - 15.7, sometimes 16. so thats okay then? i just need to start looking at boosted run readings, and shoot for 11.5 ish?
thanx dino.
