Wideband for Carb setups?

I did tons of research before ordering my setup. I went with a zeitronix wide band with a map sensor and sensor for my fuel pressure. I also tapped into my TPS for my bauman trans controller and my MSD for my RPM referance. Pretty awesome to log AFR, Fuel Press, TPS, RPM, and Manifold pressure. Going to be very helpful when I intall the Blower in a week or two.
I am very happy with the quality of the zeitronix and you have the option of a Pod mount display that you can scroll through all the inputs you give it with the push of a button or a rectangular display that shows them all at once. I went with the pod mount.

Ya I thought of that but if I am tuning I gotta have my laptop to adjust timing in my MSD and also to adjust shift points in my trans, so I pretty much gotta carry it anyway. But it would suck if I had a sudden problem and didnt have my laptop with me to log.

wideband makes things easier, get your float levels right if there to low it will have a lean hole off idle usually, (from what i learnt with yrs of bike carb tuning) and I basically watch the afr gauge and run as lean as possible on front mains, then WOT from say 3000-7000 I try to average 12.5:1. I change the rears to compensate for this. I have around 40 deg of overlap@50 and it idles at 14:1 cruises in the 13s

just found this http://www.innovatemotorsports.com/products/lma3.php
right now i have the "uego" and always wanted a way to data log my set up.
it was 3 internal sensors and you can also use 5 external sensors, my thinking was just wire the uego wideband as one of the external sensors. any one try this??
edit looks like this box is cheaped and should do the same thing http://www.innovatemotorsports.com/products/ssi_4.php

I use a simple NGK setup. it was 249. It came with a quality NTK sensor.
It is not a pretty guage, but it is easy to see since it has a BRIGHT red number display.
I dont think carb guys need anything different than efi guys, we need to have a referance to what is happening in the motor. you can go simple with something like what I run, or you can go fancy with something that datalogs so you can look over the data later, instead of while driving.
If you go with a setup that data logs, I recommend getting a unit that can log more than just the A/F ratio, as you will need to reference the A/F to something else to be able to understand the data.
A/F, rpm and throttle position vs time, would be ideal, but just A/f and rpm vs time would do.
I have heard BAD things about the LM-2's rpm input, and that it is not reliable, just an FYI.

mine runs great showing me 13's at idle, but you cant use the wideband for idle - do it old school - highest vacuum at your desired idle speed
off idle my cruise is real rich - 11.8- 12.2, I need to work on this
WOT I have run my best mph with the a/f showing me 12.8. - I just jetted it leaner to show 13.1, and no track testing yet....
The wideband will drive you crazy because you can see all kinds of "little" problems but really just use it to give you good advice about which direction to go
