Ok guys I'm about to test out the eec tuner on my car but need to use the blue wire mod to get it close before dyno time. How do I do this? What do I use to read it?

Thanks.

So far as I know the blue wire mod applies to the Apexi SAFC install and readings. I'm guessing you could maybe splice a voltmeter into the same wire you do with the apexi and read the voltage the same way. You might try to PM L8 Apexing Aussie (Anastazi) about this.

I believe it is pin 76...should be white with a red stripe. That will tap the front bank O2. The blue wire does refer to the afc.

Pin 87 (White w/red stripe) is the Bank #2 front O2 sensor. The "blue wire" refers to the AFC's input for a 2nd MAF (on a dual MAF car) that we use to monitor O2 values. You'll get a voltage from 0 - 1 VDC. For max power, tune to .94 volts at WOT. At idle and cruising, it should oscillate above and below .45 volts (once warmed up).

EDIT: OK, its pin 87 on an OBD-II Duratech. I have no idea what pin to use on a Taurus. And the .94 volts at WOT is also for Duratech only. Your results may vary (especially with a pushrod motor).

I have a 3.0 Duratec 24v and a 3.0 pushrod.

Thanks for your help anyway.

If you are doing this on the DOHC 3.0, then .94 volts should just work fine.
