Hey guys,

I have seen some of you using small 7-segment LED panels for displaying your AFR. Where can I get one of these? I've searched google for keywords, but can't really find anything.

^ I'd be interested in this also. I know there's a wiki page about turbo'ing a miata and it discusses the various requirements regarding voltage and other stuff of the LED panel, but I also was not able to find it online.

Looking for a 7-segment LED numerical read out. I've seen it in a few cars on here.

ebay has some cheap meters. I'm thinking about getting this one 5 digit LED Digital Volt Meter Voltmeter 19.999V DC - eBay (item 350324733375 end time Apr-04-10 00:00:49 PDT)

Would anyone have any input on how could you mate a screen like that to an existing display. I have the PLX 300 which is a box with a digital display. I would like to some what make a connection extension to an aditional screen, like the one above, to mount cluster gauge or rear view mirror.

How do you convert the voltage to display the AFR equivalent? My LC-1 has an analog 0-1V and 0-5V out I believe.

I think with the PLX 300 you can separate the display by extending the wires connecting it to the board. I was going to do this for a friend but we never got around to it.

Anyone know of any solution? I'd get a gauge, but the less gauges the better.

****, Im afraid of opening that **** up and having to buy another WB cause I fucked up. JayL has the PLX also, he was the one that mentioned this idea to me, and didnt get around to do it neither.

There is a description on how to use an ebay volt meter and the LC-1 wideband on the Miata Turbo Faq page.....

Thanks, I didn't see that.

Anyone know if changing the settings of the LC-1 analog out on the laptop affects the serial out? I have the serial out going to my ECU.

Joe Perez

No. All outputs of the LC-1 are independent. Only the two analog outputs can be rescaled, the serial output, being digital data in nature, is absolute.

Thanks, Joe.

Now I have to play the waiting game for the LED panel. Maybe I'll use my regular voltmeter in the meantime.

Ta da!

Or the green one...

Or the blue one.


You can use it for montoring many different functions other than AFRs if you decide to change your setup later on and it is 1/32 DIN size.

rescalable.

I have the PLX SM-AFR and DM5 gauge and love it. The guage has a numerical display in red with red, yellow, and green LEDs around the perimeter. Very easy to read at a glance. That and a boost guage are the two that I really want/need visible at all times.
