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.

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

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 :P

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

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?

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

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.

    • Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.
    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
