are you referring to the calculator? i have a ti 87 i think..can i use that?

yeah but you would have to write a program for it and build a box that you connect through the bottom of the computer. basically what this progranm would do is read the signal the box gets from the voltage, and the calculator would convert that to an airfuel ratio. it could even graph it for you. im still having trouble figureing it out exactly, but its been done before.

I'd rather see someone turn my OEM clock into a readout for a wideband, now that would be cool.

"Hey man, why does your clock keep bouncing all over the place like 11.68 and 12.46 and ----?"

My buddy Jim put his FJO wideband display right in the stock spot of the crx clock, looked pretty badass.

yeeeeeah, thats what im talkin bout.

ok let me get this straight. Can I install a wideband O2 in my car and read the signal with a voltmeter? (then convert to air fuel)

I think on a NB you would measure the direction of the swing, and the duration above the O2 switch point, in order to just determine higher or lower than stoich, then graph that, NB is only going to get you +-stoich, and thats it, no real accuracy past that. Certainly no use on a turbo'd setup. A digital voltmeter will just bounce all over the place and you wouldn't know wtf is goin on. Old school simpson 260 analog meter would be better.
Inside your ECM for NB they have calculations based on the slope of the change, and do %trim based on that.

no, you need the wideband controller

I made one of these and it never worked. I think I might have killed the chip soldering the wires onto it though, if I try it again I'll use a socket.

you could use the DIY WBo2 kit and a volt meter and it'll work like that. he kit is appx $35 + the sensor, only problem is that it uses the NTK sensor not the bosch sensor, so it almost comes out to the price of a T.E. kit or something.
