Do you match it to the lo fuel readings or the cell on the datalogging page?

I watch the wideband display and adjust it at idle AFR and match with datalogging screen.

Re: UberData Question
 
Hmmpf... I tried datalogging again today. No unplanned computer shut downs :-\

Anyway, I went out for a bit, around town, on the freeway and then back home. First off, I'm not convinced that my WB readout is matching Uberdata. I tapped wires into a power and ground source of the ECU and then plugged my WB power and ground into that (I think A25 & A26 - or something like that, I'll have to look). My idle jumps around a little and it's never dead on... it goes from .3 off to .5 off to more... Should the WB display be a little more stable, or do I have something else wrong? When I'm datalogging, it floats between 4 squares and it's a bitch to have settle to check the WB reading.

But, I thought ---- it... I'll use what I have and give it another go. So I adjust the entire map about 5% less, except I added 5% to the highest boost column because it was pretty close to 12:1 already. Burned the chip and now it's running 17s at idle... creeping up to the 19s and I'm thinking this is totally NOT normal. So I go back, try another burn and get pretty much the same thing. So I went and reburned my original map, put the chip in and my dataloggin values are all like 2 points higher than they were before... WTF? I'm running the same map, but getting completely different values? :P

Ehhh... maybe I'm not burning the chip right. :-X

Well, I fixed all of my connections and am still off by about .42 AFR... So I changed it in the Uberdata files and it's working much better, thanks. :o
