If your going to get some boost dont waste your money on that uselss AFR gauge autometer sells. I dont know why people buy that crap. Its not accurate. If you want some accurate readings get that stuff Stephenmax has. He has a palm pilot wideband O2 reader. Thats a AFR reader right there. If you want some good readings get a EGT gauge. That will be way more accurate then that autometer AFR crap. I see alot of young high school "KIDS" with that AFR stuff. I know someone here thats boosted and has not hooked it up Looks good thought since its black and white.

 

Don't you need a wideband O2 sensor for the AF ratio gauge to work. The stock O2 sensor is not that precise.

 

IMO...it's just an expensive light show

 

You mean like this one?

All they ever did was Knight Rider back and forth and then show rich when you floor the car.

Shadow needed something to fill a hole on his overkill 4 gauge pillar for now. We would put gauges in the center console but that's home to the 7" screen, dvd, center channel, turbo timer, and e-manage. The gauge is ancient back when he first got his SC and he wanted to fill out more gauges and we'll replace it when we get a wideband O2. Notice the nice speed dent on the side too...makes it perform better.

 

i bought mine for my upcoming nitrous setup, but i will have to agree...it's just pretty lights, lol. It was the cheapest gauge in the C2 line-up so i got it first. I know mine can't be right, since it says i run lean all the time i may get a wide band Bosch O2 sensor and a Uego controller to make it worth it.

 

that gauge just lets you know if your rich or lean. Its useless. The wideband used thru a laptop or that palm pilot, that will graph it for you and really let you know if your lean or rich. That gauge does anyone no justice. Listen to the owners of the gauge. I dont own one. I use Apexi gauges. Just dont want any person thats planning in boosting to run out and get one. How much do those things cost?

That's what I have. Here are some pics since I know everyone LOVES pictures....

This is my wideband o2 sensor display. I spent $330 for it so I can tune my fuel. It doesn't have datalogging capabilities, but I use something else for that. You can buy a wideband controller from plxdevices that has datalogging capabilities.



This is my Zemulator setup. That's what I use to datalog any sensor I want to... (ie wideband o2).



Yes, the ricer AF gauges are garbage. They tell you NOTHING. All you see is whether you are rich or lean and when in closed loop, you see it toggling back and forth. DO NOT spend your money on this. If you TRUELY want to see your stock narrowband o2 sensor voltage, then tap into the o2 sensor ECU wire and read it on your multimeter. SAME thing... minus the light show.

You can use an EGT gauge and/or a wideband o2 sensor. Both are very useful.

 

If you want one in gauge form, then AEM makes a wideband one with bothe the sweep and a digital readout....but it stops at 11:1 AFR, so it might not be too good for bosted apps...

 

Yeah, I've seen those. One person at the drag strip had it in his STI powered AWD 2dr Legacy. Pretty sweet car. He said he paid $400 for his AEM wideband. It was nice and is a clean setup. I did notice it stopped at 11:1.

The PLX device wideband controller goes from 10:1 to 20:1. If it's outside that range, it simply reads "RICH" or "LEAN".

 

or "AIR". I bought the M-500 with the datalogging capabilities. $509 but well worth it.

 

True, but if you have something to log the output of the AEM gauge (ie laptop, greddy e-01, etc.) it will show you a/f ratios lower than 11:1.

 

MisHap, Where Can I find a 4 guage pod at, and also a guage bracket for the center consoul under the radio>

 

Shadow bought that one off another .org member. It was made custom by a stereo shop by molding on two Autometer pillar pods onto the factory pillar. The work was really clean and it snaps right on like factory.

Shadow tried one himself but it ended up a 15lb mess of bondo, fiberglass, and took screws to hold in.

The center console piece can be done pretty easily. For Shadow's car we ordered some carbon fiber sheet and we'll cut it down to fit w/ the waterjet. I might be able to get one made for you in a week or two when I do his. He just wants nitrous switches and indicator lights but the design will pretty much be the same.

Just PM me if what size gauges and I'll see if they can be made to fit in that space. It's a part we've been thinking of producing anyway.

 

I got a 1/8" thick sheet of ABS plastic from a local stereo shop. Then I got a 2" hole saw bit and after a lot of precise measuring, I start cutting and trimming. I used a dremel tool and a razor blade. It's great and I think I did a good job.

 

Has anyone used the Tomei AF gauge? It's supposed to be one of the better ones out there. What about the greddy warning af gauge?

 

Just wondering, would the A/F gauge have any practical use in a nitrous setup as opposed to the more gradual hit from turbo/sc setups?

 

Not that pricise is huge overstatement. Its pure garbage.

The only difference it can tell between rich and lean is .8V and .9V. Thats it. You telling me thats precise to a degree? Its useless.

Wideband uses 0-5V to measure a/f ratio accurately. There is absoluetely no way in hell you can accurate or tune even to a REMOTE degree with that a/f gauge.

I will put $100 on it. I got money to gamble.

Your better off getting a EGT gauge. Too hot=lean low temp is a better sign of being rich. The safest approach would be dyno tunning with wideband

 

Thanks. I was going to get the A/R guage but I'll replace that with the EGT guage, but the reason for more pods was becuase I'm going to Run the NX kit along with the turbo. So once I get that installed I'll be PMing you for the center console pods.

 

thanks Jay. Time to take my a/f gauge back and claim that it didn't, ahem.., fit in the "socket" properly. yeah, that's the ticket!

 

Gotta be the devil's advocate here. I bought a narraow band gauge and a nitrous kit last year. The gauge saved my motor. It read lean every time I sprayed... after a bit of looking around, I found out that I had my vac lines reversed (dry kit). Had I not installed that gauge, I would be running on a different motor now.

Other than the binary readout of the gauge, it has no accuracy. The fact that it looks like it should 'sweep' leaves everyone with a sour taste in their mouth when they see it in action... especially when they learn that the O2 sensor doesn't send a 'sweeping' signal to the ECU. It might as well be a single LED that turns on when lean. Anyway, you can't tune with it, only avoid some trouble.

Now that I'm boosted, I have a OBDII logger, wideband gauge with logger and and an EGT. I keep the narrowband gauge hooked up so I can cross-ref the wb gauge... those wb sensors can foul up quite a bit.

An O2 sensor does send an analog (sweeping) signal to the ecu. A signal ranging from 0-1v. The ecu however only cares about the 0-.3v and .6-1v range being too lean and too rich. Our gauges (narrow band) read the whole spectrum though.
