Gidday all,

I'm thinking about buying a lambia sensor and having a go (carefully) at tuning my car myself. ( have a friend who's tuned a few vl turbos etc) Just wondering if anyone can recommend any brands and know prices? I know my way around my pfc pretty well now - it can't be that hard - just time consuming but a great learning experience. Every time I get my car tuned it costs a good whack - and I'd like to check AFR's every now and again anyway.

I saw a thread sydneykid made ages ago about buying a lambia sensor and hiring it out for a week for a fee - did anything come of that?

Cheers

Its lamda :) Or more commonly known as a wideband o2 sensor.

I recommend innovate motorsports LM-1. I have one and its great. Only thing is that you have to buy it from overseas. Thing is IMO its kinda hard to isolate load points on the street for a novice tuner. Dyno is always best..

or you could buy local from techedge

That's what I've done - got the 2E0 kit with bosch wide band oxygen sensor - it was the cheapest option.

I'll get it tuned professionally but it'll be a good thing to be able to check AFR's whenever I want.

Hmm I've been quite keen to look into this, so roughly what are we looking at here for prices?

And do these sensors go into the factory O2 sensor port? I'm reading into it now but a quick short cut to the basics wouldn't be so bad? :P

If you read on the techedge website they say not to mount it too close to the turbo as they won't read right. The best place is before the cat - probably in the down pipe - that's where we'll mount it.

It wasn't as expensive as the ones from the states - all up under 400 AUD with the wide band O2 sensor although I'm not sure how good it'll be.

I use a Bosch LSM-11 sensor in conjunction with a Motec meter. The LSM-11 has been around awhile and is probably getting a bit old now in terms of the technology. Sensor itself was $500+ the last time I bought one, but that was quite awhile ago now.

Wide band oxygen sensors have come down in price a lot.

http://wbo2.com/lsu/sensors.htm

I got the 0 258 007 057.

I see that motec use the 6066 which uses a bigger opening and is quicker to react but apparently can cause it to be sensitive to exhaust gas temperature fluctuations (probably most likely in a turbo application) because of this.

The 7057 was around 150AUD if I can remember correctly.

nice info!!!

so has anyone got any concrete info on AFR's and what other people are using? like race teams etc etc?

No idea about race teams - a normal number from what I've seen is 14.7:1 for closed loop (apexi pfc) and under full load 11.9:1, although I've heard people say they lean out to 12.5:1? @ full load - guess it depends how safe you want your tune.

There's a good topic on tuning with a pfc in the stick forced induction quick reference guide at the top of this section.

      R33 GTST Sh*tbox to Polished T*rd

      By Yeetus · Posted

      Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -

      Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.

      Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.

      Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
