I've never had one, what's the best buy nowadays?

 

Have always used and had the best luck with the AEM widebands.

 

Can't complain about my AEM UEGO or whatever. Works as far as I can tell. It's not like I can sniff the AFR and say that it's reading anything but perfect. It uses a Bosch sensor, which is OEM on VW and such. So they are common, easy to replace, but a little pricy ($70?). Definitely a good Wideband O2.

 

So the AEM comes with the whole package? I'll look it up.
Thought Plx was gonna come up.

 

i used aem and plx. both work good. right now im using the plx tuner edition with a black dm-5(which is discontinued) gauge piggy-backed off of it. i prefer plx but its personal preference.

 

I have had pretty much all of them.

PLX - Board went out. Only two output options.

Innovate - Went through multiple O2s before it burnt out. Can customize output.

AutoMeter - Fine exept the 30 second delay time BS. (Not the best if you run WB closed loop - car pulls fuel thinking it is rich). Output scalar is funky.

AEM - Excellent especially for the money. No complaints at all and can change output with a switch to suit your needs.

Can't think of a couple others right now. I do hear the new version PLX is supposed to be better though.

 

I like my mtx-l. Direct logging is nice if you have Neptune.

 

I have an ngk afx. The NTK sensor is nice.

 

I've had Innovate wideband controllers w/Bosch O2 sensors and an XD-16 gauge in 2 of my cars and have not had any issues with them. I've datalogged both in Crome and eCtune without any problem.

 

You can buy the off the shelf Bosch 17018 sensor to replace the AEM EUGO sensor. Same plug and has the "trimmed resistor" as well. Can find these at any major auto parts store, in stock, for about $60. Just replaced mine 2 weeks ago.

 

Plan on replacing my s200 with something newer...leaning towards Neptune

 

Can't go wrong with NepTune.

As far as the WB02, I'm using the PLX SM-AFR with the DM-6 gauge. I originally bought the PLX because I wasn't planning on running a gauge (only going straight to to ecu) but there was a combo deal at the time and I couldn't pass it up.

I'm really happy with the product, there hasn't been a single glitch. The gauge is thin enough that I surface mounted it with a strip of good double sided (RC servo) tape instead of using a pod, keeps it out of the way but right next to the cluster.

There are a ton of options out there, they almost universally use the Bosch LSU series sensors, so that is really a non-issue. If you just need to log and don't need to add a gauge, PLX, AEM, Innovate, Daytona Sensors are the first few that come to mind.

Beyond that, if you want a gauge, it's pretty much choose your flavor from the same manufacturers and a few others.

Pretty much everything falls right around the $200 range, but I do remember seeing a real no-frills controller/sensor only a couple of years ago that was significantly less.

 

Im using the MTX-L and like the output for closed loop and data logging.

only 150 shipped if you search hard enough

 

That's a good price for a quality Innovate product! Might have to see if I can find one and throw it in the wife's Grand Am for shytes and giggles.

 

AEM has been reliable for me, no issues at all also backed by Bosch replacement O2
Have the 30-4100 kit

 

certainly cant go wrong with neptune i run it in both my civics.

as for that sm-afr setup, im using it and personally would say dont get it if you live in a cold weather climate. the connection from the unit to the gauge is a single wire like an auxiliary cable. the connection is crappy and when its below 40ish degrees it doesnt send data to the gauge. the colored afr sweep around the outside of the gauge still works but the numbers on the gauge are just blue dots. once it warms up or if you turn the key on and off a few times it finally works. highly annoying.

my turbo car has a plx m300 wired in and its fantastic no problems in many years, and it has a 0-5v output

 

I have never heard of anyone else complaining about this, but my wideband offset (the voltage correction for the wideband signal) has changed with engine load in two cars now. If I calibrate correctly for idle/cruising, the voltage the ECU sees at WOT appears one or two points too lean.

I've got no idea what causes this or whether I can do anything about it, but direct logging with an Innovate wideband is crucial for me because it allows me to tune straight off the wideband controller without having to worry about the changing ECU offset.

 

If you have to offset voltage then you have a grounding issue. Use an ECU ground and check all your chassis ground or add them as needed.

 

I am using the PLX sm-afr with the DM6 gauge as well, wired up to S300, and it all works great. I live in a climate that sees well below 40 degree temps, and it works all the time for me, although I do notice that it takes a few seconds to heat up and read right when it is really cold out, as in below 0 C or 32 F.

My one issue is that I wired the power to a switched source, so it turns off when starting the car. Whenever I dig into the wiring again I am switching it to a source that stays powered so that I can log afr on startup.

 

I have all new grounds for the engine and transmission. This has happened with the same offset in two cars. The only common factors are the engine and the ECU (and the installer, lol). Maybe I should post a new thread...

 

had my plx sm-afr for a long time before the box took a crap on me and has thus far been my favorite.

the aem dual channel unit i had didnt last so long going car to car. Box took a crap.

Zeitronix zt2 was great until the circuit burned

I have the NGK AFX which is ok....I just hate that it doesnt recognize the o2 is already heated for ignition cycles. I ended up wiring the power to a switch. When you are trying to tune cold starts, its a pain in the *** when you are dealing with engines that require more than your standard startup calibration.

I am trying the innovate MTX-L next to use the direct logging features for NepTune, KTuner, and Nismotronic

 

For what it's worth S300v2 now has the ability to accept the WBo2 digital signal.

 

AEM Wideband $160+the comfort of Amazon all day.


I think that is the place I bought mine from, don't remember. But Amazon has a great return policy and it is pretty dang cheap for a new wideband + sensor. I know the picture isn't that great though.

 

Which brands of WB02 sensors send out a digital feed back?

Also what are the advantages of digital vs analog feed back?

Thank you.

 

I believe Innovate Motorsports is the first to go 100% digital with the LC-2. I'm not sure if any of the other companies have followed suit yet or not. The LC-2 still has the two analog outputs along with a digital input and output as well.
