Ethanol Content Analyzer

-Details-
Vitruvian Engineering decided that we want to help the enthusiasts on the forums get a hard-found discount on Zeitronix stuff, as we’d love to see more widespread monitoring/logging (the correct way with a wideband), so we’re hoping this deal makes up the mind of some people who might be on the fence. The goal is to get at least nine participants, though there is no cap. However, there is a rather short timeframe limit, and this will be a one-time group buy closing at 11:59pm on July 17th. Get in contact asap is you want to participate.

-Pricing-
The discount will be a set percentage off of retail that will be applicable to anything Zeitronix sells (so check their website www.zeitronix.com for anything you want that you don’t see below). The discount will based on how many people order a ZT-2 or ZT-3 setup (the ZT-3 counts as a half-person for the GB), and the discount will be have 3 possible tiers as follows:

=========================================================================

-Why Zeitronix, and why ZT-2?-
For Audi drivers I recommend the ZT-2 wideband over the other Zeitronix products and over the companies’ widebands (I personally run a ZT-2 in my B5 S4 with a handful of Zeitronix accessories [EGT Sensor, Boost MAP Sensor, Fuel Pressure Sensor, ZAVT-1 Alarm Module]). The ZT-2 has the following advantages:

– Painless RPM logging with no additional modules and an open OBD II port –
When logging actual air-fuel ratio with a wideband, it is important to simultaneously log other variables from the car’s ECU (such as requested AFR, stock oxygen sensor voltages, MAF flow, etc) to fine tune or monitor a vehicle’s tune. A wideband has to be able to log RPM in order to easily correlate and align the data from the wideband sensor with the car’s ECU data. Some of the competing products (like the Innovate LC-1) require an additional RPM logging module for the Audi’s, at additional cost and complexity. Other products (such as the Innovate OT-2) use the OBD II port to log RPM, making it impossible to log the ECU variables at the same time. The Zeitronix ZT-2, however, self-contains everything needed to painlessly log RPM out-of-the-box, and with the ZT-2 logging RPM it is as easy as splicing a single wire.

– Future-proof and Versatile –
Though all of the hardware required to read wideband AFR’s comes included in the ZT-2 package, there are however a plethora of add-on’s that allow the ZT-2 to grow with your budget, or adapt to your needs as your build(s) progresses. Every ZT-2 comes equipped stock with the ability to simultaneously read 4 inputs (in addition to RPM and TPS), which can include:

-Exhaust Gas Temp- Most turbo Audi’s are equipped with a stock EGT sensor, however the stock Audi EGT sensor is used as an upper-limit failsafe only. This means that the stock EGT sensor doesn’t usually register a loggable reading below their failsafe threshold (which is usually a high value that you ideally wouldn’t often be going above [945*C for the B5, for example]). So, the stock EGT sensors are good for their role as an ECU failsafe, but they are useless for monitoring the exhaust gas temperature where your car is going to be running 99% of the time. Exhaust gas temperature is an important tuning parameter and affects knock threshold and engine reliability. With the ZT-2 and Zeitronix’s EGT probe, EGT’s can easily be monitored and logged with high precision.

-Boost/Vacuum MAP Sensor- Similar to the EGT sensors, most turbo Audi’s are also equipped with a stock boost MAP sensor for the stock ECU. However, like the stock EGT sensors, the stock MAP sensors also have hardware/software limitations with regards to loggable/readable values. The stock MAP sensor was originally implemented with stock boost pressure levels in mind (below 10 psi), and thus it is limited in it’s ability to log values above a certain threshold (which is usually around 22 psi max boost on a B5 S4, for example). Many of the stage 3 and above turbo setups are boosting well above 22psi, and if they were to rely solely on the stock MAP sensor readings, they would be flying blind above ~22psi. An analog boost gauge in the cabin is better than nothing, but without a way to log/correlate the boost values with log data from the ECU and wideband, an analog boost gauge doesn’t do a whole lot when trying to review logs or possibly have a 3rd party fine tune a ‘remote tune’. Together with the ZT-2 and an in-cabin gauge (ZR-2, LCD or DashDAQ), a Zeitronix MAP sensor can also be used as an in-cabin boost gauge. I recommend the 5-bar MAP sensor over the 3-bar, as they both have similar accuracy (down to ~0.1psi), though the 5-bar has a larger range.

-Fuel/Oil Pressure Sensor- The stock B5 ECU doesn’t have provisions to monitor fuel pressure. Whenever a turbo car is modified near the threshold of the stock fuel system and above, it is wise to monitor the system’s fuel pressure, as a sub-par or faulty fuel system can cause lean AFR’s and potentially lead to catastrophic engine failure. A standard analog fuel pressure gauge that people often install under the hood is good for setting a base fuel pressure at idle, but a weak or struggling fuel system usually manifests itself by not being able to keep up the fuel pressure at higher load/revs (not revving in neutral or idling). Similar to analog boost gauges, under-hood analog fuel pressure gauges lack the ability to log or monitor the fuel pressure throughout the rev-range, to later correlate with the rest of the log data. When utilizing an upgraded fuel system (possibly with multiple pumps and multiple potential failure points), it is wise to use a Zeitronix fuel pressure sensor during the tuning process to make sure your fuel system is up to snuff, and later to monitor the health of the fuel pumps/system as you daily drive.

- ZAVT-1 Audio-Visual Warning and Trigger Box- The ZAVT-1 is a innovation by Zeitronix that acts as an alarm, making a noise and igniting a red LED when certain user-defined thresholds are breached . The ZAVT-1 can also be set up to trigger a relay, as a system failsafe. For example, say you want a warning when the car is running leaner than 12.5:1 AFR above 4000RPM: you just set those warning parameters in the user-friendly software, and every time the car goes leaner than 12.5 above 4000RPM, an alarm will sound and a red LED will turn on (an output to trigger a relay for some sort of physical failsafe is also configurable). The ZAVT-1 can use the input data from many different sensors, including boost, AFR, RPM, fuel pressure, TPS, IAT, and EGT’s.

- Black Box Data Logger- This is used in conjunction with the Zt-2 (or ZT-3) and essentially serves as a one-button logging trigger and memory card, so that you can log on the fly without a laptop.

- Easy Presentation and Analysis of Logs- The Zeitronix ZT-2 is one of very few widebands currently supported by Nyet’s ECUxPlot, which is the de facto Audi B5 log plotting utility. ECUxPlot is a log graphing program that takes the logged data that you get from the ECU and automatically correlates it via RPM with the logged data from the Zeitronix ZT-2. ECUxPlot has automated correlation, filtering, graphing, and picture exporting features, which make analyzing the raw log data infinitely more palatable and easy. Example graphs from ECUxPlot can be seen HERE.

- User definable 0-5V inputs (log methanol injection flow for example)- The ZT-2 has 2 user definable inputs that can be logged simultaneously with AFR and RPM. Some people have been using it to monitor their methanol/alcolhol injection, for example, as seen HERE.

Simply put, proper logging is some of the cheapest insurance you can get when working with thousands of dollars worth of hardware, and there is nothing like the peace of mind that comes from having hard data to verify that your car is running properly and not in danger. And that’s not even mentioning the performance and optimization b e n e f i t s that come with proper logging

If you got lost in this monolith of writing and are wondering how you can get in on the group buy, go back up to the payment section above [:D]

What’s vitruvian engineering? Looks like a company whose address is a house in mississauga?

I’m not familiar with their product line, any chance someone could point me towards a good option for just afr with on board data logging? I don’t have a need for a gauge, but I want a good sample rate/logging period.

Thinking of picking something up to use on multiple cars.

Hmmm… I might be interested. I always liked the Zeitronix products.

Zeitronix stuff is always great. I have used their old AFR setup on many different cars

This is great Mike, I think I am going to add a ZT3 + second sensor to the ZT2/LCD kit I already have, that way I can watch both banks.

I have also been considering another alarm trigger and relay

Sorry, I forgot to set my preference to email on replies.

Ha, already going with the internet sleuthing, eh Saki :wink: Vitruvian Engineering is my startup (this is jibberjive btw, in case you missed it in the OP), and it’s based out of Utah (registered address is to a house right now, to save you the trouble of searching the business name and google earth-ing it :P). I haven’t set too much up with it quite yet, but if/when I finish developing the parts I’ve been working on, I’ll be setting up a nice site, getting everything in order etc. In the mean time, I’ve been developing my business connections, and Zeitronix is one of them. Thought I’d see if I could help the enthusiasts (specifically the B5 people, who are sorely lacking in the logging department), and if that sets me at a better pricing tier with Zeitronix at the same time, all the better.

Yeah, I’m going to be doing a more thorough explanation of “Why Zeitronix, why ZT-2?”, but in the mean time I’ll just give you a short run-down and say, I recommend the ZT-2. The reasons are: expandability/future-proof (super easy to add a ton of different sensors to, like fuel/oil pressure, EGT, boost/vacuum, ZAVT-1 alarm box/relay, IAT); Ease of install (everything needed to log RPM, TPS along with the AFR is integrated into the box, unlike many other systems [including Innovate]); Cost (with Innovate, for example, in order to log RPM at the same time it requires and additional RPM module, at an additional cost (logging RPM with the wideband is necessary to correlate the AFR logs when simultaneously logging the ECU variables over the OBD II port)).

I’ll go into more detail later, but the ZT-2 is a powerful little setup, and that’s what I recommend (and run in my own car).

Using it on multiple cars is an awesome idea as well, and that is what I’m going to be doing as well. I’ll detail how I wired mine up with special connectors, so that I can just pull the box out of one car and toss it in another car. If we get above 5 people, I’ll include all of the necessary wire splice/taps to install the wideband, RPM hookup and a MAP sensor so that the brain can be pulled out and swapped to a different car without any tools. I’ll also put a link up to the tail-sniffer that I’m going to be getting to use on other people’s cars that I tune.

Quality stuff 8)

Stereo wideband would be awesome, doesn’t get much safer than that. The ZAVT-1 alarm trigger is also really cool. I’ve got one, and it could be very useful, especially if you wire to a relay to disable something, as a failsafe (for example, you could wire it to the N75, so that it instantly shuts the boost off). There really is nothing like the peace of mind all of the monitoring give you.

Any chance you will be running a special on the Dash Daq

nice, thanks for the info. I like the sounds of how yours is set up.

I’m interested, I get paid on the 15th so I’ll be a late entrant.

That is a guy working from his house in Mississauga, a suburb of Toronto. Must be a popular name. I guess the historical reference is a common one.

Anyway, good luck with the business!

Mike, I will pull the version info off of my ZT2. It may be the older version, I got it in mid 2009. If we can configure user 2, that would be great.

That discount is off everything store-wide. I just didn’t list everything they make in the list. We can do a dash daq for sure!

Nice. Keep me updated about how serious you are.

Yeah, there’s two or three others as well (but none in the automotive aftermarket, and none in Utah), that’s why I had to settle with www.vitruvianengineers.com (I really need to get at least a placeholder up).

sign me up for the zt-3 sensor and gauge
black bezel / red led

I think i’m gonna mount it in the left center vent, I’m looking for a vent gauge holder if anyone has one.

Sounds good Josh. Hit me up at sales@vitruvianengineers.com and we’ll get your payment going and get you on the list!

Still going on for a short time further.

How much longer will this be going on? I think I need to order a new sensor and can figure out for sure tomorrow if I do.

Shoot me an email this weekend, and we’ll get you set up. :slight_smile:

I already have a wideban on the B7. Can I get all the components from you and just tap into my current wideban sensor… Or do I need to add another sensor. I have been wanting to get this for a while

The first post has been updated with a ton of new info! The group buy will be going on for 6 more days.

I believe the wideband O2 sensor on the B7 is a compatible Bosch LSU 5-wire sensor that would work with the Zeitronix ZT-2 or ZT-3 brains, though I can’t guarantee how the wideband controller or stock ECU will react to splicing/splitting the sensor’s signal.
