I'm using an AEM UEGO as well. Thing is, I'm not totally confident it is 100% accurate. I have a feeling it might read a bit rich, otherwise my tune is extremely rich. Frequently seeing ~12.5 on cruise. But I need to ask my tuner to check how accurate it is next time it goes on the dyno.

That said, I'm otherwise happy with the AEM. I've just finished wiring it into my G4 expansion harness which was very straight forward. The Zeitronix kit looks the goods as well though!

Mine seems to be pretty accurate and very responsive!

I use Innovate MTX-L, appears to be a tiny bit laggier than my old Innovate LC-1.

I installed a AEM UEGO on Phil's S15 not long ago and they seem pretty good in terms of response, however his is mounted a little closer to the exhaust housing of the turbo where as mine is mounted pre cat.

so where is the point of difference in all these products?

the sensors will be quite similar yeah? just bosch units or what-not? is the difference in the controller bit? i thought all we want it to do is send an accurate AFR and that's it and let the ECU handle the rest?

if you are aussie there is no reason why you should not use the techedge. you don't even have to buy the display with it which makes it cheaper.

been using them for years, and i own 2 units now. cannot fault them at all. I even had a issue with the long sensor cable and he was nice enough to replace it for me for free when it was not really even covered under warranty and the turn around time for the repair was only 2 days.

all parts and cables are available to purchase seperatly, so you don't have to buy a whole new wideband sensor if you destroy the power cable or the wide band cable.

all he does and all he has ever done is build wideband meters, no one knows as much about wide band as this guy.

cannot beat that shit.

Yep I splashed out on a TE WB3A2 and all manner of cables and adapters a few years back . It has all kinds of logging abilities most of which I'll never use . It's wired into a Vipec plug in nowdays and works really well . The only thing I ever did was drop it in to TE in Canberra to adapt it to their current fastest I think Bosch LSU 4.9 probe . It heats up faster than the one it came with and my tuner requested a new probe when the plug in was fitted and tuned .

If you only want an 02 input for your computer you can buy them cheaper and not pay for features you aren't using . I use the small LCD display so I know what's going on when the lap top isn't online .

I'd buy Tech Edge again , cheers A .

yeah i got the 3A2 as well, had it since 2007 i think... its still going strong. its got the usb interface. its been dropped, wet, left in 55deg + heat for days on end and its still going strong.

I also go the basic 2j2 unit.

if you want a good unit for tuning cars then grab 3a, if you just want one for one car the 2j2 works great.

these things are rock solid, why bother with the seppoes crap ? you dont use AEM computers why use AEM wide bands ? its just silly.

I got this depo gauge...seems all right has Bosch sensor..

Started reading lean, turns out my fuel filter needed replacing...replaced fuel filter now wideband reads error...tried to calibrate it but no response..:unsure:

Pretty sure sensor is still fine , if unit is dead can I just get the techedge so I can link it to my adaptronic?

I seem to misplace a bookmark about wb testing, AEM was at the bottom in terms of how fast it reads and accuracy. A .01 difference compared to LC1 and the other brands that was tested. I had an LC1 first unit was DOE got a new one and it worked peachy.

Im going to try and google n see if I can find the article.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
