Wideband O2 Sensor

[iruvyouskyrine]

Hi all,

Just wondering which wideband oxygen sensor to get. First thing is what are peoples thoughts on running an O2 gauge? I don't particularly want to but I spose it would be good to monitor AFR's. This car will be doing lots of drifting and I was hoping to just run oil temp, pressure and water temp.

Will be using an Adaptronic select plug in R34-GTT ECU.

Would ideally like to run something from the tech edge catalogue because they are Australian. All I really need is a sensor to feed wideband AFR's to the ECU.

Cheap, simple works and recommended by Andy @ Adaptronic

Innovate MTX-L, serial connection is a match made in heaven with the Adaptronic ECU.

Having a gauge is a personal preference thing. Personally I look at it after doing any work in the engine bay but if you're hammering it around the track you won't so much as glance at it

edit: I'd have to agree with the MTX-L. I couldn't get the serial output working on my AEM EUGO but with a mates MTX-L it never had an issue. (same PC)

Email adaptronic for the gauge, there is one that can be wired into the ecu and give you real life reading on both the gauge and loges with the ECU. I've got that on my Kia, works very well and very handy when comes to road touch ups.

yeah that would be the Innovate MTX-L lol

techedge 2j9, i have the older 2j2 works well and uses a common sensor.
aussie company in canberra, have good tech support

If you're not really fussed about the gauge, how does the LC-1 compare against MTX-L? Have heard reports about it being "hard to wire up" but I'm not sure if that's a legitimate complaint. Some people shouldn't be let loose near a soldering iron

There is an LC-2 newly released but adaptronic not carrying it yet.

I wired my LC-1 up, I am an idiot and solder once a year. It isn't as pretty as I would have liked but it works fine.

Not sure how accurate these are, i have mine installed pre cat and got the car dyno'd today and the readings were a fair way of.

Both or one of them might be due for a free air calibration?

[Blackkers]

I had a brand new AEM UEGO that was reading about .6-.8 more rich than at the tailpipe after comparing 2 other widebands.

The only difference is that the permanent sensor is installed pre-cat obviously. Not sure if that's normal

The LC2 seems to be a better unit so far than the LC1 I used to use. Great for if you don't need or want a gauge, otherwise the AEM is a great unit for the price.

Id go AEM man, They're one of the best in my books.

Agreee with that. My LC1 seemed to read great. Had a 10% difference with the sensor used on a dyno.. trusted the dyno sensor and ended up maxxing out 555cc Nismo Injectors with not enough power to match.

Ditched the Dyno and operator when he was "going for the 300kw" regardless of the rich detonation, and took over 10% fuel out from 3500rpm and above on the road on the way home. Turned out the LC1 was spot on.

I just made sure i re calibrated it each Oil change. 3+ years now.

I got 4 years out of mine on ethanol, but it wasn't the sensor that went, it was the LC1 unit that failed.

It is carbon that buggers the sensors, especially if the heater can't keep up with cleaning it off. I know tuners that replace the sensor every week or two as they cop a hiding from running rich on petrol.
