Wideband Data Logging


Recommended Posts

So I got myself a wideband gauge and it comes with a 0-5v data logging output, however it gives no information about what software to use or where to get it, so I did a little google search to no avail.

I'm asking if anyone use's the function, and if so explain how, like did you make your own usb cable and what software did you use?

In my search I did find some software for PC (I have a mac) but it never mentioned anything about a usb cable.

also does the software need information form the obd2 plug?

Links appreciated!

Cheers - Daniel

What wideband is it? Typically they give you the software.

You could try you put something together with an arduino board, but to make loggign useful it has to include at least rpm, throttle position and preferably boost.

stock ecu with a apex neo piggy back

heres a link to the sideband I bought - http://www.ebay.com.au/itm/360746100476?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

not sure if its a popular brand or not, but its called "EVO" gauge, I like the seller, and I like the race tech gauges, so I just bought this off him.

and yeah I thought it would have came with software/ or at the least instructions, I'll see if that brand has a website and go from there, but thanks for the help guys, and I couldn't imagine trying to make my own board or whatever, however it did come with a sheet with readings like 0v = 10.0 afr 0.25v - 10.5 afr etc etc to 5v = 20.0 afr or something like that anyway.

also the r34 uses the consult port, not obdII

So if its only a 5v output then I believe you will need some sort of medium capable of turning 0-5v signals into an output a laptop etc could read. My AEM wideband has a 0-5V output which is hooked up to my Link G4 and it also has a serial output that you can plug directly into a laptop (if you wire a serial plug to it)

This is why it prpbably didnt come with software, 0-5V outputs from the gauge are usually to just output to an ECU that can read the signal

I'm not sure what it was intended for, it may very well be to output to an ECU, I found a few arduino boards on ebay, but they all log data to a fat32 or SD card, and they still don't incorporate RPM.

I'm sure I've seen some guys doing there own tuning with a piggy back who use the data logging system to tune, heres the thread here - http://www.sau.com.au/forums/topic/327734-apexi-afc-neo-safc-tuning-issues/

note the graphs.

That guy's wideband IS the datalogger. It's all Innovate gear.

All you have is the wideband. You need a datalogger as a separate thing.

What you should probably do is sell the cheapo wideband you have to someone ehow wants it but doesn't want to datalog, and buy something like the Innovate jobby that will actually get you what you need in something more practical.

Your alternative is to move to an ECU that will accept the 0-5v input and log it along with everything the ECU itself is doing. Then you can get the data out of the ECU.

Either way, you are going to have to spend some money. A standalone logger would probably be lowest cost if you can find one that will easily pick up what other signals you need to log. RPM is relatively easy, but many other things like load, boost, TPS etc are more work (and expense) to pick up, especially if you're doing it on the cheap. The Innovate style logger is essentially the same as the standalone option in that respect. Easy to grab RPM, not so easy to grab everything else.

Thanks mate, I never bought the gauge with the intention to data log in the first place, but because it mentioned that it came with it, I was hoping it would be relatively easy to do it.

I will keep the gauge and I probably won't tune my car myself, if I do, it will only me minor adjustments till I get my nistune or power fc.

Thanks to those that responded :)

Im guessing they meant you could data log through an ECU. The Power FC will allow you to do it through FC-Edit but you will need the datalogit and laptop connected to do it. Where as an ECU like a Link will log it all the time (as long as its wired right and logging is enabled)

I agree with the above. If you REALLY want to log it then get an AEM UEGO or an innovate wideband gauge that has proper support for it. Although I dont see much point in logging it with what you have. Best off just using the gauge while driving. Glancing at it every now and then

An alarm for lean would totally suck unless referenced to boost. Otherwise it will go off every lift of the throttle. ....

Yeah exactly. Off throttle the gauge will go out of range (lean) because there should be no fuel going into the engine

There is no point having an alarm on a wideband because it fluctuates so much. I highly doubt if it only has a 0-5v output that it would reference boost so I would just keep the alarm off. If it is mounted on the A-Pillar (just assuming) then usually you will notice if it is not right under load.

Personally I'd ditch it and get a proper one. The Innovate gauge is a pretty nice bit of kit, and costs less than $200 from memory. Same with the AEM unit like I have. Not sure what the deal with the Innovate's are now, but the good thing about the AEM gauge/Wideband sensor, is that it never needs free air calibration. I know the old Innovate stand alone wideband kits reqired free air calibration, but not sure about the gauge kits.

That's a bargain, and integrates to nistune.

If I was in the market I would get it for sure.

:glare: whaatttt why don't you guys tell me this before I go out and spend 200+ bucks on a wideband :(

Gauge is mounted where the stock R34 gtt gauges are. nothing on my A pillar.

Not necessarily. The factory ecu can only use a narrow band. The nistune software can utilise extra inputs to log (through the laptop)

Most wideband can simulate a narrow band output that the ecu uses, meaning that you can get rid of the stock sensor.

    • I do think it's weird I had it for 2 weeks then the issue came up out of nowhere and progressively got worse. I would've imagined changing everything in the ignition system would've resolved any ignition related misfires but still has the high rpm and idle misfires that seem unchanged. I would've thought if it was fuel related it would happen all the time unless it's the pump losing pressure when it gets hot. If it was the ecu I would think it would do it all of the time.  Something I noticed when I had it all apart was a pretty decent coating of oil in the J pipe coming from the throttle body. The weird thing about that is the pcv that goes to the intake is blocked off. So that has me wondering if the oil is coming from the turbo because that's the only thing that could get oil in there. This thing does sound like it spools like a mofo like I'm a former dsm guy and the only stock turbo I've ever heard spool this loud (to only go up to about 5psi) is on a diesel truck. And the recirculated bov is really loud too I had a TurboXS RFL and this thing is just as loud and being so low on psi seems a little weird. I don't know if any of this is or isn't related but just trying to make sure I'm not leaving any potentially helpful information out. 
    • So latest update. I replaced the ignitor with a jspec unit from enjuku. It felt a lot better at first although it is a little bit cooler of a day than it has been. Warming up didn't have as much misfire sputtering as before. Went on a 10m test drive. Felt good, a lot stronger though I was taking it easy on the boost. On the return trip started getting the cutting out at higher rpm again and was getting worse the longer I was driving. Took it easy the rest of the way home. Before turning the car off was getting the normal idle sputtering I was getting before.  So where I'm at now, entire ignition system has been replaced with upgraded components. Plugs still gapped at .8mm. Removed the fuel cap in case it was building too much reverse pressure I'm the tank, didn't help at all. Now I'm still on the same tank of gas the fuel treatment was in, I'm thinking if I can run that out and then refill with fresh 93 maybe  the treatment is too concentrated in some areas but doesn't explain that it only does it once the car is warm. I'm leaning towards fuel pump or injectors but if the injector was clogging I don't think it would make it shut off like it has but then fire right back up like nothing happened. So my current guess would be the pump. Without a fuel pressure guage no way to test or check it while it's running.  So that's kind of where I'm at. Need to start testing fuel components and ecu/wiring but I'm at a loss of what's the next logical step and procedure for testing it. 
    • @niZmO_Man thanks for that info, lucky I bought the gktech ones 🤙.
    • Never cheap out on brakes, tyres, suspension. I learnt the hard way at Oran Park lol
