Zeitronix Wideband reviews
After only a short time of using the Zt-2 with the LCD I have noticed something. The instructions do say "Do NOT tune vehicle while driving", fair enough. They shouldn't be held responsible for someone elses mistake. But what they should have said was "We made sure you can't read the LCD while driving so you can't tune". It appears, on my specific screen, that the response time of the LCD is far too slow for the refresh rate or data rate it recieves. The A/F always shows a blur after the decimal because the LCD can't properly display quick enough. I am sure this could be temperature related but I don't see it getting much better with 70º. The numbers are also small and not very easily read.
If anyone doesn't quite understand what I mean by 'LCD response time' try doing a little research on the subject, mainly concerning computer LCD display monitors.
Other than that everything appears to be working perfectly. I will now need to do some real data logging to get this thing tuned (because the LCD isn't much help).

Looks like a blur. A rich blur. I won't really know untill I collect data.
edit: I just went out for a bit and noticed the heat did seem to help quite a bit. But it isn't feasible to tune while driving since the Zt-2 doesn't have a tach display. I will make some data files tonight and post them.

Im in search of a good quality wideband with a digital readout only where the numbers are big enough to see while doing WOT sprints. Thats what shy me away from this unit, the readout numbers are really small.

im really considering the PLX M250 with the gauge
i would go and watch the short video here
http://www.plxdevices.com/2InchGauges.htm
there gauge seem to have a pretty fast refresh rate so it could used
im in the same boat i just want to do a 4th gear pull and make sure i dont ever go above 13:1 or below 11:1 for now that will be good enough and then ill just wait for the ZEM and i datalog everything with it

:Umm no...I will be tuning on the dyno not on the street so no need for datalogging really. It is a nice feature but not totally necessary for what I want a wideband for. I want the digital numbers to monitor on the street so if it runs lean I can let out of it before something gets damaged.

I would also suggest the Dynojet Wideband Commander. Prior to having the Zt-2 I questioned the use of an analogue gauge but now I see that it might be very useful. And it also does data logging.

Trying to read a wideband while driving is really useless, if the a/f did go haywire you could not shut down fast enough to prevent damage if it was really off. Datalogging is the way to go.
Thats why I chose the FJO and the Maximizer because it will shut down if the a/f goes above or below a set value. Even a fpss will not shut down fast enough to prevent damage on a total failure.

My 5.5 is a lease and because of that I am somewhat limited on mods and I also know that 1 engine is all I can probably get on warranty and I do plan on racing approx 24 events this season so I need every safety measure available.

Of course I played stupid and said nothing, I had already did the compression test and knew what was wrong.
PS that was a 200 shot testing on an old seldom used road. Regardless if I had of had the maximizer and FJO wideband that would not have happened, because I have duplicated the setup to prove it.

Get the Zt software here
Get my twenty minute drive home here .
The files are much smaller than I thought they would be. Be sure to setup the software for 6 cylinders and omit the boost, EGT and user data when studying my log file.
I have also noticed that my WOT A/F varies by one full point on different passes according to this logger. I am still learning this thing.

I figured It would be a good thing to see as your driving..
I have no idea what datalogging is..can someone explain please

datalogging is taking information and storing it to take a look at it at a later time.
you can monitor a number of different sensors (rpm, speed, afr, flow, etc) and make adjustments with your fuel settings based on the information that you get.
I am planning on using my afr and rpm to tune my safc

Actually it's VERY accurate for a narow range of AFR's. more acurate than widebands, because the voltage difference from 0-5v is all used withing a narow band of AFR's from 13.5 to 15.5. instead of a linear band from way down low (8.5ish) to way up high (20ish). So, the resolution of the narow band is better for a short range, but the range of the wideband is better.

I'm not sure if I agree with that...at least OEM 02s aren't accurate. They don't measure AFRs, but whether they're on the rich or lean side of stoich as the ECU toggles them back and forth around ~14.7:1.
With boost, your AFR will be well past the valid range of a narrowband 02. Narrowbands are good at telling whether you are rich or lean, but not how rich or how lean, so they can't really be used for tuning FI cars, since you're dealing with 11-12.5:1 typical ranges.

I am going to be tunning while driving but Ill have the passenger logging everything in. I am just going to pull over to make adjustments. I bougt the screen so I dont have so many freaking gauges hanging around like a ricer! I am a ricer but like to keep it to a min.
