not sure on that one snoz, the zirconia needs heating to work properly (the two white wires are for heating)but not sure on the titania.

checked my fuel usage and ive hit 190km on half a tank. looks like the dirty afm's could have been a big contributor to the poor fuel economy. should get the new o2 sensors next week, i'll fit them next and see how that goes

Tunes not going to make a huge difference as I doubt nothing mechanically has changed requiring different fuel and ignition loads. Could removing from fuel from the tune by they generally run lean then shift AFM drops when acceleration occurs, so could get some better fuel economy, but I bet it's something like AFM, o2 ect. I've got a set here that are used, but worked fine previously Eric.

They work like a thermocouple (from my understanding), which means they would read different because of the two different types of materials.

Thanks clint, as i said, got a new set of o2 sensors coming next week, and i will keep a eye on the afm's. if there is any problems with them. 'll come and see you.

are you back from holidays yet? still got to get that price for a set of front rotors off you.

ok makes sense.. but is the difference in material a longetivity thing or do they operate differently due to the difference in material?

operate differently and are not compatible with each other afaik

just fitted the new o2 sensors. had to buy a special socket to get the sensor out (rare as rocking horse poop too). will see if this makes a difference.

If anybody needs to change there o2 sensors and is SOR im quite happy to help as the socket makes it very easy.

if u bought o2 that are RB25 compatible, couldnt u just get the ford EF o2 sensor from repco, as it mentions in the general maintainence section that that is compatable with the RB25, i did that and im sure it was under $100 for it, plus some connectors, and no special tool required,

a bit late now, but might help someone else that is looking thru this thread

I got the o2 sensors for $77each, Gtr sensors are alot harder to get at than the gtst so it was easier to get the correct tool for the job

  • 3 weeks later...

got the fuel economy down to 13.8l/100 without the tune highway/city driving. o2 sensors are working perfectly (pfc sensor check screen). was hoping for a tune by now but other things have come up so it keeps getting put off. knocked up a catch can at work and that is now fitted so hopefully no more oil on the afm's.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
