Enquired about these sensors on TT.net the other day and got a reply from this gentleman who is hopefully organising a group buy in the near future!

 

I believe the price range will be 300ish dollars and hopefully we could get a couple of sensors and a switch to check each bank!

 

Here is his email!

 

 

Hi, guys. This O2 sensor works just as well as or better than FJO

or Motec systems... it has much more user functionality and features

and is less than half the price of other systems. Here's some info on the

wideband unit...

 

1) It will utilize the Bosch LSU-4 5 wire sensor, which is cheaper, easier

to replace, and more readily availble than the NTK L1H1 sensor used by

other companies. It is practically impossible to find a NTK sensor

nowadays... and replacements run in the $300-400 range... whereas the

Bosch ones run $100-150ish.

 

2) It comes with a great data logging unit that logs rpm, A/F, and 2

additional user selectable inputs (I'm going to hook mine up to boost and

maybe timing). You can log anything that puts out a voltage... like

maybe some EGT gauges or fuel pressure gauges, etc. It is available in

both PC and Palm versions!

 

3) Comes with a LED display that shows the A/F ratio and a series of LEDs

to indicate lean/rich status.

 

4) You don't need to weld an extra bung into your exhaust because it will

REPLACE a stock O2 sensor (there's extra circuitry that converts the

wideband voltage output to corresponding stock O2 sensor voltages, so the

stock ECU can use the wideband O2 sensor). I don't know about you guys,

but for me, this alone sells me on the unit. I don't have the time to

take my exhaust system off, try and find a good exhaust shop, and hope

that they weld a bung on properly, and then put my exhaust back on. It's

much easier to just remove a stock O2 sensor, and throw in the wideband.

 

5) The unit does free-air recalibration adjustments in order to get very

precise readings as oxygen sensors are known to lose calibration over

time.

 

6) Currently, we're working with the manufacturer to get possible on-board

RAM so that you don't need to keep a laptop or palm pilot hooked up to

datalog... just do a run and download it later. Other possibilities

include USB support (currently it hooks up to a serial port). These are

still in the works though and not certain if it will go through or not.

 

The current versions that are already in production use the NTK sensor,

but since the NTK sensor is so scarce now, it is being upgraded to use the

Bosch sensors. The ETA for production is sometime in May/June, and once I

beta test a unit, we'll be ready to start the group buy.

Dont tell me - It means 35mpg and 400bhp on a stock TT and we need a new 2003 design 64 bit ecu to go with it to make sense of the greater sensortivity?

 

No seriously tho what does it mean?

Mark, put me on the DEFFO list m8 ;)

 

CheerZ,

Hi,

 

I am not a complete expert on this so other people please jump in!

 

 

Willie the wide band O2 sensor is as far as I can make out the most accurate way to tune your car, if you have one of these then you can mix the air and fuel to the optimum ratio! The car will get more MPG as requested LOL, and more BHP!!!!!!

 

No more visits to get your car retuned when you have added another mod, the only other consideration when you have set it up, is detonation. If for whatever reason the car is detting then you have to use more fuel to cool the chamber!!!!

 

I am not organising the group buy, what I will do is send Bernie the link to give him some sort of gauge of interest!!

 

BTW the price is probably gonna be $3-400 depending on numbers, my mistake!

Also Steve E has met Bernie and he runs a 600+bhp Z which he got taken for a spin in, nice to know we are not dealing with an anonymous figure!!!!!

the wideband alone won't help much...it's just an accurate lambda sensor.

To actually make use of it, you'll need something that is able to finetune your mixture like a Electronic Fuel controller(Apexi AFC, Apexi Power FC, HKS F-con, HKS S-AFR, HKS GCC, Greddy Rebic, Greddy Emanage) or something that is able to make realtime changes in your ECU, like the Zemulator.

Thanks Eric,

 

An oversight on my part there, I took it for granted that folks would realise you would need a fuel air controlling medium to alter them!

 

Is there any news when the Zemulator will be out and can it work in conjunction with conzult?

Mark, I have a Zemulator at the moment.

I'm beta testing it in my project car (a turboed NA) and I'm looking with Ash Powers into possibilities to combine the Zemulator and ConZult into one device.

 

Anyway ..Sofar the Zemulator is working very well in the Turboed NA.

I'm running 0.5 bar of boost on a almost unmodified NA engine (only major modification are 370cc injectors).

Did a few testruns against a TT running a JWT chip and 1 bar of boost.

The TT had trouble keeping up with the "NA", so it'll be interesting to see what happens if I can get the NA to run higher boostlevels :)

 

-Eric

So thats what you been up to!!!!!!!!!

 

Have you got the NA pistons in there?

 

I presume it would be posible to synchronise the wide band O2 the wide band to run with this set up?

Mark, that's indeed one of the things that have kept me busy lately :)

 

engine internals have not been changed/upgraded.

So yes, it still has NA pistons, heads, valves, camshafts, oilpump.

It still has a compression ratio of 10.5:1.

Things I changed were the injectors, oilpan, oilfilterbracket and I added a few extra oil and waterlines to/from the turbos.

I know it's a bit risky...but it's an experiment and sofar the engine holds up fine.

 

A wideband o2 is ideal for tuning your car with the Zemulator and Conzult

But once the ideal fuel/timing maps have been created or the mixture has been optimized, you don't really have the need for the sensor anymore.

I think EGT's are more usefull in the long run.

 

-Eric

Ummmmmm,

 

Why do you think EGt's are more useful?

 

The thing is a lot of people on here seem to modify their Z at least once a year, so having the ability to tune their own car could be beneficial!
