I am thinking about adding two afr gauges on my car (dual exhaust)for tuning. Any one have any input?
 
You can weld a couple of 02 sensor bungs into your headers, down near the collector.
That way you can remove the blanking nut, screw in the 02 sensor and hook it up to an AF gauge and tune away.
This way keeps it all hidden, unless you want a constant reading on the dash.
 
I am thinking constant on the gauge pods I have. I am interested if any one is using them. I am thinking it might be a good way of watching the health of the engine also.
 
There are several threads on this. I bought an innovate setup before I went with the Holley HP EFI, and it is built into the system

Don't waste your time and money on narrow band, you need wide. A setup with computer and logging access is very handy as opposed to "just a display."

"About" 200 US is what you'll have to spend. You do need to be careful. Be careful with the sensor. Various non-approved gasket materials / chemicals can "kill" them, and running them unhooked is not recommended. The sensors are the same size as a "Ford" 18mm spark plug. I bought a couple of 18mm nuts at the local fastener's joint way cheaper than the bungs you buy.

This was the one I bought, "back then"

Just received the Innovate O2 wideband kit via priority mail a few moments ago, and yesterday I received Tom Zalenski's "Autotune" program via email.

Turns out the Innovate software is pretty bloated, and didn't like W98, so I spent the night installing W2K on the partition I'd had 98 on. After getting everything installed, I only have 90MB of hard drive left!!

The Innovate gauge has trouble codes built into it for various things and has given me a heads up a couple of times.
Once my car hiccupped going down the road and a glance at the gauge showed 17 something and then went back to normal (fuel pump died the next day) but I already had gotten one an tossed it in the trunk the day it showed lean for a couple of seconds.

One time it started flashing E9 (low voltage) and I popped the hood to find the alt field wire broken at the terminal.

Personally I think having one on both pipes is a bit of a waste of money and work, because we usually make changes that affect the whole carb and engine and not just one bank.
Mine is built into my gauge pod like you are planning, and I have had it for over two years without so much as a blip of trouble with it.

I paid about $170 for my Innovate wide band on Ebag.

This is the one I have.

So with dual exhaust with no cross over on is ok? This is all new to me.
 
I use an Innovate unit. Just reads one bank. Crossover won't matter since the bung will be forward of the crossover.

People make a big thing of "reading both sides." You CAN put bungs in both sides and read them, but that is not going to necessarily pick up an odd problem say, with one cylinder.

But engines are not normally completely isolated "left to right." The INTAKE connects them, whether you are running a 360 or a 180 intake.

The thing is...........these 200 dollarish O2 setups are NOT lab, dyno room instruments. What "they are" is heads above "what we used to guess"
 
Thanks 67, I have put so much time into this I do not want any unforeseen, preventable problems that why I am getting anal. A few hundred after all this is insurance for me. I figure a clogged jet, bad valve etc might show up before I blow something again.
 
You can put an O2 in each bank but put a switch to toggle between left & right O2. This is what I did on my RoadRunner.
 
I have a single AEM UEGO gauge hardwired into my 71 Demon - if your car is a 25.5 caged tube chassis race car I could see the need for 2 separate gauges but a street car? NO get one gauge.. I have mine mounted in the drivers side front pipe of my X pipe - wires go right in line with the speedo cable all the way up to the firewall

Crappy pic but that is where my wideband and volt gauges are - under the dash, mounted in 2 pre-exsisting holes - very nice for tuning, can get a carb dialed in in around 2 hours with it
 
Thanks guys giving me ideas, like the switch thing. Just spent a ton on a trans and do not want to do a motor, retired AF so limited budget.
 
I think you can get a single gauge with dual readers, but, bottom line, they are a handy tool, I have one gauge in one bank and my EFI in the other, like one poster said the Innovate gauge has error codes, it has helped me on numerous occasions, partiularly on secondary air door adjustments and a crappy battery!, i had a battery that died but i had not run the car for a while, charged it up and fired the car up but my AFR gauge was giving me an error code of low voltage, sure enough, battery was ****, new battery all problems gone, handy little tool to have, my gauge reads contsantly so I can see if im running lean or rich, I wouldnt be without one now.
 
Before the install make very sure that atmospheric air cannot find it's way into the header, anywhere between the valves and the sensor, and also up to about 2ft on the afterside.

Guy my crap is tight as hel!. Ever blow a 727?:toothy1:
 
I have an Innovate AFR gauge in my daily driven Dart.
Great tool to have and monitor the engine at times.

On another car I've had 2 gauges installed in both seperate exhausts, but that car/engine has largish cam and a longram intake system on it so I needed the 2 gauges to try to tune both carbs.
Got a clip of it on my youtube channel somewhere.

Kind of what I have, I have to run a vac pump for power brakes. One big afb though

Not sure what this means, but no I'm a stick-man.
And I've rebuilt dozens of 727s

Ima thinkin, you're implying space under the car is at a premium. 's ok. I only meant that headers pull air in anywhere they can. If it finds your sensor, it will skew your readings and give you diagnostic fits. But I'm also thinking that you already knew that.
My TTIs like to pull air in right at the merge point in the collector.My fault;I took them through 4 Manitoba winters behind my teener. That swapping thing ended in 2004.
 
Definitely use two, whether you use one gauge on a switch or two(I'd prefer),
a leaking/not seating exh. valve, misfire(regardless of cause) in one cyl.,will show
as a lean shift on that bank. The lambda sensors will have heaters that must work
regardless of signal readout switching w/ one gauge,I'm not sure exactly how much
$ you're saving w/one gauge,but I'd like to know what both sides are reading at the
same time,seeing one side go out of "norm" could alert you to developing issues
B4 you find out the hard way.
I have a F.A.S.T. system to dial in setups for cust's, which uses a dual bar-
graph display, and VERY responsive in real time. It also records/stores up to 25
minutes of data w/2, & 50 w/1 sensor for playback/analysis,NICE. But it is a tool,
not an install item, would be nice tho' if someone offered one.
 
Honestly, I'm not sure if it will be the insurance you're looking for. Vac gage will show you something is off too. Seeing it, seeing it in time, and seeing it quicker than you're eyes, nose, ears pick up on something - is a serious question to think about.

If you want a tuning tool that also provides a degree of monitering, then heck yes. Look at Innovate, Racepak and FAST. They all have plusses/minuses. Over on racingfuelsystems forum, I observe that Innovate and Racepak logs dominate.
 
I kind f like this one any feedback on it?
