Question about A/F Gauges

mcmmotorsports · Dec 1, 2005

If they are so inaccurate and everyone says they are a waste of money, then how come companies still make them?

Same reason they make turbonators...

There are good ones, they just cost $350+

I know Wideband is the way to go, but just curious about these narrow band setups that are still available.

They make them because peaple buy them thinking they are getting something.

The real ones like said before are 350+.

I run a innovate motorsports xd1/lc1 combo.Its within a few ticks of the wideband on the dyno..

Guages like the autometer one is nothing but a light show.BUT the cool thing is with the setup like innovate has .If you already have a autometer gauge ,they have the stuff to turn it into a REAL A/f gauge.

So if I buy an Autometer Ultralite A/F gauge, later on I can add the Innovate stuff to it and have it function as a Wideband?

YEs,

But i like the xd-1 gauge that innovate uses ..All digital read out ,you can change its colors etc..

The autometer gauge used with a LC 1 still won't give you what you need....numbers

Use a R-C to make a low pass filter (with around 1/2 sec bandwidth) and it will work fine and stop going up and down all the time. All you need is an average reading of rich/lean... these 2 $0.20 parts from radio shack will get you the same results as a $300 wide band gauge

No they don't, you need real numbers for actual tuning info. Rich-Stoich-Lean doesn't tell you anything useful. For instance, explain what "Rich" is telling you, and what exactly is Autometer's standard for "Rich". You also need to record A/F data for tuning, and an Autometer gauge does not do so.

Ask in the forums section on their web site. The autometer gauge will no doubt be an analog hookup to the LM-1 datalogger.

No it will not give the same results as a wideband . Filtering the signal does nothing to widen the range of the sensor.
