DIY Wideband logging

[Jay Z28]

Has anyone successfully built the DIY wideband o2 sensor (www.diy-wb.com) and logged the output along with other engine parameters? I'm toying with the novel idea of using the A/C pressure sensor harness as the wb02 signal line since Datamaster will log this signal and the PCM expects the 0 to 5v range needed for the diywb02. If anyone has done this or has any other input/suggestions, pleas post.

Thats the solution others discussed, sounds good to me.

Where else has this been discussed??? If the A/C pressure sensor does truly use a 0-5V range, then it should be no problem wiring a WB sensor to it. Let me know what you find out...

Yes it is a 0-5 mv signal with the 5 mv being provided by the pcm. It is on the same circuit as the TPS switch on my 93.

The only way I know is I melted that sensor on the race car (!AC) and it shorted out and also grounded the TPS sensor!
