LC-1 Wideband Air/Fuel Ratio system for Autometer A/F Ratio Gauge

  • Sponsors (?)


I just got one! :) I've got it "installed", but not wired, should have it done tomorrow or sometime this week (blower install going on too haha). I mounted the box between the trans and sheet metal above where the trans crossmember is (there are a buncha wires there, and it seems clean, so I figure it'll be good!) and I ran the wires up through a lil whole I poked in the rubber dust guard for the shifter. It's a real quality unit from the looks of thus far, I got mine for $179.99 from DTN!

Oh and if you don't have an xcal2 you can also datalog just the A/F on your laptop PC using the included serial cable and software.

Has anybody used one of these for their Autometer A/F ratio gauge? I want to my gauge into something that would actually be useful...

So, any opinions?

Cheaper kits out there? So far this is the cheaped I can find...

Thanks,

The LC1 is wideban AFR that output an analog signal to eithere a datalogging device(laptop etc) or an analog gauge. That Autometer gauge is actually a the normal narrowband AFR gauge. You won't see any AFR numbers, just that little LED going around the gauge, giving you and approximate AFR(Rich, Stoich, Lean).

The whole point of Wideband AFR is to get precise reading, meaning, actual numbers.

If you want a gauge type wideband, the LC1 Standalone Gauge kit from Innovate Motorsport is better, but of course more expensive.

I have the LM1 AFR unit with datalogging, can't wait to bring my car out of storage to tune with it:nice:

Not exactly true. The analog output for datalogging is completely different than the output for the autometer guage. The analog output for datalogging has a range of 1-5 volts and the datalogger you use has to have a mapping for the guage to know what a/f ratio equal what voltage.

The output for the autometer guage has an adapter that converts it to a voltage range of 0 to 1 volt. Each light on the guage represents an exact a/f value so it is still very accurate, just not very easy to read in my opinion. I prefer having numbers to look at.:nice:

Yes, I know that, they just wanted to make a Wideband AFR cheaper by using a Narrowband Gauge display:( It's simply a comparator unit.
 
The reason I'm using an autometer gauge is because it matches my other autometer gauge lol. The only time I need to know my exact A/F is while tuning, and I can do that by plugging my Xcal2 into my LC-1...or hooking up my laptop. With 20LED's the autometer gauge shows a wide enough band to know if I'm dangerously lean (or for that matter pig rich).
 
i've already made the mistake of buying the light show a/f autometer gauge.. seems to me like this setup will give me a 'pull over now' legit warning with the gauge now instead of the bouncing lights.. and then for exact #'s i can hook up my laptop in the pass seat for tuning / datalogging.

if i'm wrong with that rational please tell me, otherwise great find i'm going to pick one up next week.

What is the difference between the LC-1 and the LM-1 and which one is the most accurate?

They both have the same accuracy, just different applications.

LC-1 is to have a wideband AFR reading only, which means it only outsputs a signal for either a gauge or a datalogging tool(laptop or any data acquisition device.)

LM-1 does the same thing as the LC-1, but also has a display for the AFR. It also has datalogging capabilities by itself, meaning it can record data without a laptop. Of course, to view it, you can upload it to a computer later on. It also has multiple inputs to log many other sensors in you car(rpm, fuel pressur, oil pressure, ECT, MAF, etc). It's also upgradable to have more inputs, external AFR gauge, etc.
