Buy, Build & Use A Tech Edge A/f Ratio Meter

[Duncan]

Well on a GTR you really need to put the sensor after the front pipes join so you get a reading (average) from all 6 cylinders instead of front or rear 3 only.

But for a GTST I can't see why not? Closer to the exhaust ports means a more accurate reading

any of you racing guys got any second hand A/F meters you wana sell ?

Or you could by two kits from TE and get a reading of the front 3 and the back three, be good to compare anyway

[Oosh]

The GTR thing makes sense, but 2 x WBO2 kits is getting a bit exorbinant, my only other issue would be with comparing the accuracy.

It says it's setup to emulate a Bosch LSM-11, what do Skylines run by default, and how close are they to this?

My guess would be there's not much difference, and that it shouldn't effect the car much, but if it did you'd notice the shit fuel economy pretty quick!

Looking thru the stats on these, they have an simulated Narrow band outpur (NBsim), is anyone using this?

i.e. Completely replacing the stock O2 sensor with the new WB one, then plumbing the NBsim output in to your ECU, or are you just mounting both?

<{POST_SNAPBACK}>

The recently sold race car (not a Skyline) was done this way, it worked fine. The only problem is you have to leave the unit in the car all the time, if you take it out there is no lambda sensor input to the ECU ie; no closed loop running. I did that for a couple of days without thinking about it, driving around (rally rego) to signwriters etc and it sure guzzled the gas.

While I am tuning the Stagea (for a week or so, in all conditions) I wil run NBsim, remove the standard S&N lambda sensor and replace it with the F&W one. That way I won't have a cable running through the cabin and an expensive lambda sensor hanging out the rear. Asking to be hit or stolen.

Hi SK,

The dicksmiths whisper 2000 is no longer available. But it has been replaced with a better unit: http://www.dse.com.au/cgi-bin/dse.storefro...duct/View/Y1140

My question is how do you modify the microphone so that it somehow detects knock from an engine-mouted clip?

Can someone post up what pinging through one of these chassis ears sounds like?

LM1 vs techedge? WHich one SK do you prefer?

Thanks

[PHaT MR30]

I have been in contact with tech edge and will be organising a group buy for those interested.

Will get the ball rolling after i get back from Drift Nationals this weekend

Hi SK,

Suggestions follow;

1. I haven't seen one of the new style, but I assume it can be modified to suite. All it really needs is a long piece of shielded cable so you can clamp the mike in the engine bay and have the amp and headphones in the cabin. If someone has the complete Autospeed article, maybe they can post it up.

2. The one I saw had no mike mods that I could see, you just clamped it in a convenient place, the standard knock sensor retaining bolts work for me.

3. Sorry, not me, I don't have a portable recorder these days

4. I have used the TechEdge yet, so I can't really say. I chose the Tech Edge this time (over another LM1) mostly for the 1MB logging capacity on board and the number of logging inputs. They are extra cost items on the LM1, plus I like making electronics kits.

cheers

any idea on price?

also anyone got a cheap source for a exhaust clamp/venturi pipe?

Price depends on number of people GENUINELY interested in purchasing

[MattSR]

I'm keen

[NewKleer]

id be interested in one im pretty sure (well i want an afr meter, just not sure which yet)

edit: depends on price....the pre-assembled ones seem to approach the cost of a lm-1 unit after a quick check of the order page

Edited December 6, 2005 by NewKleer

[StageZilla]

im in for sure, as long as they are pre-assembled.

[PHaT MR30]

yeh i think to make it easier will keep it to a pre assembled kit the 7200 sensor and a choice of cable length.

what kit would people be interested in? I myself want to get the 2E0

[Bullant47]

I'm definately after the 2A1.

[PHaT MR30]

We will await SK's completion and see how it stacks up against the LM-1.

Oh and the G/B will be something for the new year, im sure not everone has a spare $600 round christmas time.

[Bl4cK32]

I was gunna say id be in, but not tihis time of year

If its in the new year, i may be in as well...

[NewKleer]

just ordered a 2E0 + 7057, $370 all up

How so cheap?

[NewKleer]

sorry, left out the word "kit" - im not getting the assembled one.

btw i asked earlier about anyone knowing about price for venturi pipe/exhaust clamp - http://www.rocketindustries.com.au/descrip...p?partno=IM3728 has them for $132 (best ive found so far)
