Alright my buddy is letting borrow his wideband so i can get my car tuned, its the zeitronics zt-2 wideband.but his laptop crash with the wiring diagram so i don't know how to wire it up. Can anyone help me out?

 

Pin #-----------wire color------------------function

1----------------red---------------------------switched pwr
2----------------white------------------------wideband analog output
3----------------green------------------------RPM input
4----------------orange-----------------------boost sensor input
5----------------empty-------------------------------------------------------------
6----------------yellow------------------------boost sensor +5v pwr
7----------------black--------------------------power gnd
8----------------brown------------------------sensor gnd
9----------------purple------------------------simulated narrowband O2 output
10--------------grey---------------------------TPS
11--------------brown-------------------------sensor gnd
12--------------blue----------------------------user input

saving the instructions pwnz all.

 

red to battery + (wire direct to battery for most accurate readings)
black to battery -
white wire to obd1 pin d14 (o2 sensor signal) if you're datalogging

if you're not datalogging all you need is power and ground

 

alright thanks i figured out the wiring, but have never used this wideband, let alone any wideband..isn't there supposed to be some type of on screen display of AFR?? when i plug it into the comp..it installs the cable, but nothign else happens?

btw, i'm not datalogging with it...and i'm running megasquirt, not on a honda

 

you have to install the zeitronix datalogger software. it should be on the CD that came with it, but if not just hit up zeitronix.com

 

yeah thanks, there was no CD, but found the software online
