I am currently thinking about what wideband I should get. I'll post questions for each consideration:

1. Zeitronix ZT-2 ($279)
- I heard datalogging directly from zt2 unit will not show vacuum, only boost, therefore hard to do partial throttle, so I want to datalog using uberdata. I heard also that the voltage AFR is not linear in ZT-2, so is the latest uberdata fixed for this?
- The advantage for zt-2 is it can do EGT, but so far I researched, EGT is not that useful for tuning, also not useful for tuning ignition. Am I wrong?
- With ZT-2 LCD display, not only it's too expensive for my budget, but it's also digital - not preferable

2. PLX M-300 ($319)
- I like the simplicity, but I don't like the digital display. I like analog cause it's more intuitive and i can easily detect if I'm running lean

3. PLX M-250 w/ analog wideband gauge ($389)
- This one has the analog Gauge, but with this price I'm almost considering to move up to PLX R-500, where I can detect knock. Anyone selling a used M-250 with gauge?

4. PLX R-500 ($550)
- With this, I only have one gauge display, and it's analog style. The only reason I would get this is the knock sensor. Up to now, I still don't know how effective the knock sensor is. As far as I know, the only way to tune ignition properly is with detecting knock. Is there any opinion on this? Is this one worth it to get?

Opinions? answers? Suggestions?

 

What do you mean the ZT-2 will not show in vacuum?

Do you mean it only shows boost when you are using the Zeitronix boost sensor?

I did a bunch of part-throttle tuning yesterday with my ZT-2, I just watched my boost gauge and held it at 10 In Hg from 2k up (took a little practice), then did the same with 0 In Hg. I held it right there from 2k up while watching the boost gauge... then I analyzed and made changes in my maps accordingly.

I don't have the boost sensor on my ZT-2 though...

One thing to consider... the ZT-2 doesn't work well if you are using a serial to USB adapter. My laptop doesn't have a serial port so I have to use an adapter, I've had lots of problems with it. I got it to work but it's still a little messed up. If you have a laptop with a serial port I wouldn't worry about it.

Yup that's what I'm going to be doing too. I haven't installed my zt2 yet, but even if it cant read vacuum you can use your gauges like he said. I was just gonna use my autometer gauge to tune my partial throttle. Just go through the different vacuum levels and tune my AFR to where I want it.

EDIT: Oh yah, bigwig did some work to get the zt2 to work with uberdata. The script or file that he made can be found on the uberdata forums.

Not sure on the boost/vacuum problem as I'm not running their 3.5bar (kavlico) MAP sensor. I just hooked the map voltage into one of the inputs and compare voltage to a chart I have. Going to do the same thing when I get/install the motorola 2.5bar MAP sensor.

Not sure on the AFR curve, it uses the standard Bosch LSU4.2 which most of the sensors use.

I've had nothing but good luck with mine. Great product for the money IMO.

Yup, I believe that's what Snail Tuning did for his setup. He is using the zt2 I hink to datalog, and IIRC he hooked up his map sensor and used that for vacuum reference.

I'm logging my map sensor voltage as well... but I can't tell what the hell is going on by looking at that line. LoL... easier for me to watch the boost gauge... but whatever works

 

Have a look at this wideband, display is in both analog and digital format. You can't datalog w/o a laptop though I think.

Any opinion on the other alternatives (plx question, etc.)?

I think zt-2 can read MAP with the user input. But it's not as user friendly as datalogging in uberdata, isn't it?

Well I think UD is the same way. It doesn't have a vacuum or pressure readout on there, but it does have a map readout. I'd open up my UD to be sure, but I dont feel like it.

 

sorry but how do they compare to aem uego? what are the differences?

 

need more opinion and brains here

 

have you looked at techedge? http://www.wbo2.com

I use a 2a0 with the remote display, uses the VW sensor, has both narrowband and wbo2 outputs (which will make my life easy at emission time).

It also has datalogging capability, and you can buy it pre-built or in a DIY kit form if you want to save some $$$

I love it!

my $0.02

All UD is doing is converting the voltage to an AFR using a multiplier (which is a lot more convenient than looking at a voltage, I agree).

 

DIY-WB.COM

 

As far as I know, that kit uses the expensive honda sensor which a quick search pulls up $185 just for the sensor. And right on the page, they say the kit with sensor is about $225 to build.

You can buy a ready made kit using the cheap ($50-$60) Bosch LSU4.2 sensor for under $300 from many vendors.

I'm all for DIY projects, but I'm also for the much lower cost of replacement parts. O2 Sensors dont' last forever, and for $60, I can buy 3 sensors for the price of one of the Honda ones. I just don't see the logic.

Correct me if I'm wrong though.

Check out the dynojet one. I just installed it about a month ago, works great and was super easy to install. I like it for the analog gauge, and like many others you can record runs on the unit itself, it will pick up TPS, RPM, and MAP for boost levels (or any other 0-5V sensor you want to monitor).

 

I had the ZT-2 and the serial to USB connector = teh ghey. Definetly get a laptop with a serial port or bigwig told me that they had adapters that worked fine for serial to usb. Im quite happy with my ZT-2. They have great customer service from what Ive worked with them.

If you are datalogging in Uberdata, you dont even need to worry about the datalogging capabilites of any of the widebands out there. You wont get any more accurate that datalogging directly from the ECU.

yep I use a PCMCIA serial card on my laptop. works great.
