Wideband A/F meter recomendation?

[wpurple]

I need to buy a WB A/F meter, could someone recommend a good, acurate, reasonable priced one?

Thanks

I was eyeing this one:

Looks trick, has it's own sensor, will need the bung welded in, no biggie.
My question is why do you need one, How are you going to change your A/F ratios, how often will you be changing them and why.
Contrary to what members such as celly says, I know exactally where I am with my mods and my numbers.
Have done my mods, have been dynoed (5 times) have my A/F set at 12.7, nothing will change from now on, my high bux SCT flasher has done it's work (downloaded a program), it now sits on the shelf in my shop (it's work is done)
Would be nice to see continual A/F at an affordable price, but what will you do with the numbers?

what do you do with it?

It just looks purdy.

I need a meter because I have a Powerdyne with a FMU.
Tuning will be done with a X-Calibrator.

I need one of these too so I can tune my truck. I don't want to pay the price for an AWD dyno, even if I could happen to find one close.

I noticed on the BamaChips site that the XCalibrator 2 says it will read wide band data along with everything else. Does this mean all you need is a wide band O2 sensor and the unit will read it? If this is the case then it seems that this would be the most cost effective method case you'll get a tunner as well as a wide band meter and only have to invest in the actual O2 sensor and a harness.

And just how will YOU adjust your A/F ratios?

 

[CougarX]

The XCalibrator 2 allows the user to change timing and fuel from the unit itself. I've also got an adjustable FPR in case its out of the adjustable range the unit provides.

Okay, so you are in your garage, do you just pic numbers? what numbers do you pic? you cannot tune unless you are on a dyno at the time.
Granted, you can change alot of perameters, but how in the hell do you know where you are?

 

[CougarX]

You can tune it on the road, and use the AF ratios and timing to adjust everything. Make sure the A/F ratio is right through the whole range then go through and bump up timing a little at a time till it pings a little then back off. It'll take quite a bit of testing and running but I've seen it done before, and it works pretty well. The guy went later and had it dynoed and they got very little extra out of it. Not perfect or quite as accurate as a dyno but its a hell of a lot close then what I've got now!

This still isn't my prefered option, obviously, but right now, my only other option is to go ahead and do the t-case swap to a 4406 so I have 2wd and can use a regular dyno. I wasn't planning on doing this soon and have no place to do it here so I'd have to pay someone to do it for me. I'm just looking at options right now, it was a bigger issue cause it was my daily driver, but now I have a Sport Trac as my DD so I can get to it when I get to it

Very cool, very state of the art but just how will you be changing A/F and timeing? yourself?, how will you do the above

 

[CougarX]

The Xcalibrator allows me, the user, to change the fuel and timing. Me. Myself. No computer or anything else. I can do it all with the little handheld unit.

Maybe I'm not understanding your question.

So cougar
You can change your timeing and A/F ratios? how do you know whats the best Timeing or A/f ratios for your application?
How do you know that the changes you are making are good for your engine?
say you pic, 13.4 A/F, is that good? or 12.7, is that better? or worse?
Is no when in hell you can home tune your engine with the excalibrator, for optimum performance

 

[CougarX]

I know I can't get optimum performance, but I can get a lot closer then I am now. In the end, the only extra it will cost me is a wide band O2, I'll still have the xcalibrator and can still get dynoed when I swap out my tcase and use the xcalibrator to do the tuning on the dyno. This will get me by until then, because at this point in time I'm running a 347 and a fairly high lift cam with the stock computer and tune. It runs, and it runs better then stock, but I know it's no where near potential and I don't want to hurt anything by running too lean. If anything I can bump up the fuel and run a little rich till I can get a dyno tune.

I know its not perfect, its not intended to be, but its cheaper right now then running out and buying a tcase and doing the swap and still having to buy a chip or programmer. I can't do it all at once and this will get me by until then.

 

[spindlecone]

In the end, you will need to be dyno tuned to max your program, for the money spent

Uhh . . . same way the guy at the dyno knows. Engine performance. On the dyno you get HP numbers, on the street you go by something else, say 1/4 mi times.
