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.

Thanks Ben, I just bought one for the Emo. Looks the goods.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.
