i think my search button wore out from all the searching i've done

anyway any has a DIY A/F meter?
does anyone have a schematic for it?
have you compared it to a autometer one (and yes i know its way off)

 

no one???? every one is a rich here, where are all the DTR (duct tape racing) specialist???

 

stop being a cheapo vic and buy one.. they are like 30 bucks ...i think kahren has one go ask him where he got his

yea yea, i know they are cheap but i like it the ghetto way

btw did you finaly get the R motor?

 

haha... I remember seeing instructions before.. I forget the link though... I'll try to find it if its still online/on the web

http://www.autospeed.com has a nice one.

 

there very easy to build and cost like $10 , if all u want is like an autometer type air fuel monitor, u can build one with like 10 electrical components and a 10 led bar. Try http://www.google.com

The WB_O2 is a little more involved

 

Couldn't you just make one with some LED's and resistors so that it measures the voltage? It's just a matter of measuring the voltage from an O2 sensor, right? Which O2 sensor do you tap into? I'm thinking about making a simple A/F meter for my car, since I've been wondering how it's running.

What's the difference between a regular A/F meter and a wideband O2?

 

yea, thats all it is, a volt meter, but its the matter of being able to design one

widband is more accurate and it needs its own diver circuit, u cant just measure the voltage from it. its pretty complex.

I just made one, I'll post pics tomorrow.

 

Cool. Care to post the schematics too? I'm anxious to see how you made yours. I was thinking about a simple volt meter using different colored LED's and resistors. The only thing I don't like about that idea is that more than just one LED would be lit. I'm tempted to go with a more complicated idea, but that'd probably just turn into another half-finished project and I have plenty of those already.
