Checking to see if it's possible, who did it, who tuned it, etc...

Default Give Joe at Axis a call, I know 034 does something like a stand alone

system, he had a display at the NE spring bash a couple weeks ago. Not sure on its compatibility with the ATW engine but he'd be able to tell you.

Default you could MAP tune it but are at the mercy of the narrowbands

its very possible but I wouldn't recommend it.

Default What do you mean by that? I have an Innovate wideband, but I'm not sure what you mean...

...Are the stock O2s narrowband? I forget...

Default the ECU uses the wideband O2's and a target lambda for fueling

2000 ECUs arent that "smart"

Default See my post above, the ECU uses narrowband sensors and a requested A/F

amongst other things. There are work arounds, but I would not run it on my own car if it were daily driven.

Default In laymens terms.... Your WB is not a direct input to the ECU.

That is for YOUR pleasure... ECU doesn't base 02, LTFT, STFT, timing, etc, any of that off your WB for adjustments. Uses the narrowband.

Austin, please correct me if I'm wrong.

Default Well, yeah... But, I thought he was referring to the tune being based off of the narrowbands.

Wideband is good for tuning, also for trouble shooting/alerting, which is why I got it.

Default Think it would be easier to tune out recirculation than the MAF? I was hoping to get rid of both.

Seeing that my MAF is most likely dying, I was hoping to get it tuned out and be done with it... But, the true goal is to get rid of recirculation. Why? I never really saw the point of recirculating hot, oily gas except to get rid of the BOV noise, which I can certainly live with. Plus, anything that makes the plumbing simpler is a "+" in my books.
