Setting WB O2 Output to NB to ECU

[NateDogg]

Hey Guys,

I set my cruise AFR to about 15.6:1. Right now I'm getting 14.7:1.

I'm wondering if since I made the slope of the nb output to be very narrow (15.5-14 AFR) that there is not enough 'range' for the output to ECU to achieve 15.6:1 AFR. Should I expand the 'range' of voltage slope or should I just live with this?

For example: If I make the 'range from 17:1 to 15:1 will it only operate in closed-loop in that range or will it always be 14.7:1?

Nevermind I think I found my answer here: http://www.zeitronix.com/questions/NBpoint.htm

I think I may just tune it for open loop and forget this $#!TModified by NateDogg at 11:00 PM 1/31/2007

You need to do some closed loop tuning or you may damage your motor, how are you tuning for timing?
