Ok, I'm looking into getting a wideband pretty soon. The innovate LC-1 has caught my eye. My question is this...is there anyway to view your afr without the optional gauge (xd-1). I'd like to get the gauge eventually, but wanted to know how to monitor the afr without it. I've also seen a "kit" to convert an autometer narrowband afr gauge to read the wideband signal. I have one of those gauge but was wondering if anybody has tried that. I assume this isn't too accurate as it would be a pretty rough estimate with counting the colored LED's and trying to convert that to an af #.

 

Yeah, since the Autometer has what.... 25 leds in it? If even that many?

the Innovate measures down to the .01 afr so you'd need....... about 2000 LEDS to actually know whats going on.... Probably more...

 

What would be the point of having a wideband if you cant view your AFR? The LC-1 is for people that can datalog the signal coming from the sensor/controller, by using either their EMS, or a laptop with the correct software. You can also use an analog output and use innovate's cheap dial-type gauge.

 

Although colored LEDs are pretty nifty to watch, I would rather have the ring of LEDs and the numerical representation in the same gauge. Whats considered "green" to you may not actually be "green".

As far as the translators go, they just take the 5vdc linear signal of the wideband and convert it to the non-linear 0-1vdc that emulates a narrow band output. Now if you take a higher resolution signal and step it down, it stands to reason that you lose accuracy.

I like mine. I use i for tunning only.

 

yea i don't want to use the autometer gauge...i just brought it up cause I'd had read you could use it. I have a laptop. Using that with that, could I get a live reading from the lc-1 or would it log it then view it after a pull? I"m not familiar at all with the software that would come with the LC-1. The "dial type gauge" mentioned earlier...does anybody have a link with some info on that? Thanks for the info so far guys..keep it coming.

 

You can view the AFR on the on the display or you can log it in the laptop. If you buy the kit, you can see on the laptop the AFR at any RPM.

 

if you can read the voltage in real time you can interpret your af ratio 11s are arround a volt
all the guage does is do the math for you

 

well, i think i'm pretty much sold on this...just waiting for marty to get back with me on the price they're currently running for the kit. Unless anybody else has a better choice in wideband for the same money?

 

i'm not too sure of the accuracy of this gauge, but the price seems pretty good:

i'll be either getting that, or if there is a way to use the LC-1 with a normal 0-1 volt gauge, i have a very nice DEFI AFR gauge...

 

did a bit of searching and found this:
http://www.diyautotune.com/catalog/a...play-p-57.html

based on that it seems you can use any analog gauge with the LC-1?
installation instructions are for LM-1 though...

edit: looks like the software for the LC-1 you can do the same as LM-1 in terms of programming the analog output. $200 w/sensor is not bad at all for that LC-1 then

 

You can use one LC-1 output for the 02 sensor feed to your ECU simulating a narrow band. The second output can be programmed to read 1v at 10 afr and 2v at 20 afr--then you can read the afr right from a voltmeter while driving. Of course you loose some resolution that way.

I think you can buy an off the shelf afr gauge and hook it up to one of the outputs--all the gauges do is read the voltage and convert to afr. Just make sure you program the LC-1 based on what the gauge expects to see.

I've got mine hooked into a Megasquirt ECU and can log and read the afr.

I don't think the standard software that comes with the LC-1 will allow you to read the value with a laptop while driving--would be nice if it did.

So far I've had no trouble with mine.

hmm...that dynotune gauge could be an option...anybody ever used one of those?
