I saw this on another board, that's a air/fuel led system... looks ok

to bad narrow band o2's suck *** and it's really not going to help much. Just looks like a rainbow display on your cluster

 

you are probably right on this... anyway it might interest someone gay?!

but for real... its because it cost 10$ in part... lot cheaper than APC crap...

ps: color are in the wrong order in the pics
it should be "red orange green orange red"...

 

i bet it would be simple to alter that to accept a 0-5v signal to make it a somewhat useful light show

 

why dont you just use a volt meter, and a ti89 ---- it will even graph it for you.

if you donthave a ti 89, just get a volt meter. i like looking at numbers rather than colors. numbers tell you allot more.

 

wouldnt it be waaayyy easier to spend the $40 and get a nice auto meter one?

 

wouldnt it be way eaiser to get a real one instad of a toy?

 

i made an exact same one a while ago.
it worked but i don`t even know if it is accurate or not :P
