I was wondering if anyone could explain how to use a fluke meter to measure the voltage/air to fuel ratio. Do I need to tap into the 0-2 sensor wires or maybe some of the wires running to the PCM. Ive watched other people stick the meter leads in the tailpipe, will that work?

Is there a diagram of the wires going into the PCM so maybe I could intercept the 0-2 wires right at the computer?

You first need to demuck the the o-2 sensor balast valve. Then spot weld fluke 2100 dm2 right to the o-2 sensor itself. You can use # 31 size rubber bands for this. The while driving hang your right hand out of the window to get a acurate cfm to temp. reading. Take that number or 3.15 and divide by the om reading on the fluke. That should help. If you need more help email me at: I don't know a thing about what you are talking about.com

If you have tech manual - it wouldn't be hard to find the voltage output
wire running from the O2 sensor to the PCM. You should be able to pick up
a meter from JEGS or Summit - or just adapt a voltage meter that reads 0-5volts.
If you're really interested in your A/F reading, it might be better to invest
in a wideband meter since the prices are really competitive now. You could
probably pick up a unit and sensor for around $300.

What hp said. If you are serious do a w/b 02. Otherwise get the ease software from Roe or the led indicator that Roe ships with the vec1. The reason no one wants to get rid of the led's along with the vec1 is because it is nice/easy to see what is going on. I even left mine on to compliment my w/b. Hugh...is your w/b on yet ?
