I have becauseican 3" dp but I have my wideband o2 in my high flow cat that had an o2 bung already welded into it.
ZT2 Wideband Questions
- Thread starter prsrcokr
- Start date
man, for this thread not being mine i sure am carrying it right along.
what angle do you have your sensor mounted at? My intructions tell me between 10 an 2 oclock but it doesn't appear that i can mount it between 10-2 oclock... doesn' tlook like it'll fit

I had a wideband question since we are on the subject. I placed my O2 sensor at the 11 o'clock position on my downpipe and proceeded to fish the harness through the firewall. I tried to be as careful as I could...
I am getting LAMBDA as 1.00 and AFR as 14.7 all the time with no value changes on my laptop. The data is streaming but is set at the default values. Does this sound like the O2 signal is bad? I double checked everything and there are no visible signs of damage anywhere.
Any suggestions on what I could try?
Thanks.

I don' tknow about your problem... it sounds like its not getting a signal.
I'm going to tr and put it in my test pipe... I guess we'll see tomorrow

Justin Yes the adapter should work
also, it won't work if you connect the green rpm wire to the pin labeled rpm on the ecu connector. it needs to go to igf or igt. check the linked pdf above.
I painted my zt-2 case a flat black
click pic:
I did verify my connections with that diagram after installation (wire color/plug location varies on 87-88 harness) I don't know why I'm getting theses readings for rpm off by such a large margin. I was getting a lot of elec. feedback causing the laptop to malfunction at first. I take some more readings and see what happens. Is everyone else TPS reading to 100%? Mine does not but I believe the graphs will self calibrate to the highest point (isn't our TPS 2.5V and not 5V?)

also, Justin did a great job of documenting for the earlier ecu.

Hey Justin, could you re link the ecu connectors you have on this post with the one you have with your pictures

what do you want me to do?
everythign i have is at www.bouscal.net/images/wideband/ there's a installl folder in that folder that has everything

question about AFR:
idealy is it supposed to be at a single number the entire time the ECU is in open loop mode?
Drove around a bit today ( first time ) and i saw numbers from 11.x -- 15.x and when coasting/idling i got upto 20.x
should, when the ecu is in open loop, the number be at a constant <insert number here>?

Justin - the picture you have of the ecu connector, in this tread post#25, has the idl and e1 highlighted. the picture you have with your install picture has the correct vta and e01 highlighted. i was asking if you could make that a jpg, its a psd, and attach it instead of the other.
see, i'm not understanding afr anymore... i thought i was. i thoguht that it was supposed to stay at an ideal ratio the entire power band, regardless of what the boost, throttle position, rpm, or anything was. I thought you wnated to have an ideal AFR the entire time...
can someone try and explain, or link me to some good info, bout what the AFR is supposed to be when?

do you have any data logs you can post?
for now you'll have to zip it. I've sent a message to IdealSupra to see if he will include the zto extension for attachments
here is a short sample of one of mine

I don't have a serial to usb converter yet... I havn't been doing much logging yet, i'm still trying to figure out what i'm doing :-D
as soon as i get a converter for my laptop i'll hook it up and log a couple runs

ok i have a wideband on my mk3 turbo, ill make this simple.
idle/part throttle (no boost, very light throttle) should be 14.7 but can go as high as 16.x - 17.x at idle
under boost (full throttle) the ecu will try and make it extremely rich usually around 10.x
perfect tune would be high 11's or low 12's from 3000rpm until redline
