A/F Gauges

[jmp]

I am seeking opinions/views on the accuracy of an Autometer A/F gauge or for that matter all A/F gauges which show a spectrum with three sections Lean, Normal, Rich.

For a Forced Induction car, are these generally fairly accurate/reliable? For someone who has not yet had their newly CTSC'd NSX dynoed, to determine below 12 A/F ratios, can they be comfortable relying on this gauge for the time-being?

Thoughts are appreciated???

my A/F gauge is still sitting in a box, under the desk in my office:frown:

If you like pretty lights sure why not,as for gauging your A/F toss it. its narrow band and IMHO sucks. you need to go wide band if you want to know whats really going on with your A/F . just MY opinion and you know what they say about those although I beleive it is science in regard to accuracy of wide versus narrow band A/F gauges. if you are thinking of getting one for a show car it doesnt matter but for real world use see above opinion.

Non wideband air fuel meters are mostly worthless. They are not to be used as a tuning tool, or any kind of accurate representation of exactly what his happening. The price of real wideband sensor & gauge packages have come down dramatically in the last few years. I would suggest buying one of those.

Like others have mentioned, these are nothing more than light show. Get the real wideband 02 gauges, $299 and up. Something similar to these:

autometer A/F gauge and others that source their signal from narrowband o2 sensors (majority of stock o2 sensors found on production vehicles) are completely worthless...as narrow bands only serve a basic function to tell you one of 3 things: Rich (Anything less than 14.7AFR), Stoichometric (14.7AFR), Lean(anything greater than 14.7AFR). They basically only have those 3 positions. Now I know this is a little oversimplified...but for the purpose of the question being asked here...this is how they work.

Wideband o2 Sensors measure the entire range...not just 3 options...and give you an accurate reading.

I'd reccommend any of the following:

Innovative Motorsports (http://www.innovativemotorsports.com)

AEM (http://www.aempower.com)

both companies make excellent products....but my personal favorite are innovative's products. I've used both setups for several years.

Link is no good. Leads you to a used/new car dealer/locater.

The correct link is: http://www.innovatemotorsports.com/

These sound like a great idea to me. Which ones do people find the most usable? The AEM guage or the Innovate handheld that logs vs RPM???

One comment regarding the AEM - it is difficult to read the digital readout when I have the top off due to so much light in the car.

Doh! Thanks pbassjo!

I prefer the Innovate setups....I really LOVE the XD Gauges....fully programable....color, range, item to monitor....everything!

My setup soon will be using the LM-1 w/ XD Gauge connected to my AEM ECU
