Not sure which one I have. It didn't last long.

Nothing bastard about the 6.1.  It's the chip I tell people to use because it works very well.  Most people that go all in will slow down from what I have seen unless they have a pro helping them and then they don't go faster...they just get back to where they would be with the 6.1 :)
I didn't mean that in a derogatory manner Steve. I meant that you're tuning like a 5.7 chip with the advantages of the sensor input of a wideband with closed loop on the fly ECM fueling adjustments. Sort of a using different ways to skin the same cat.

I've yet to get my 6.1 to run right.   I think it's my W/B shooting me in the foot.  I kinda wish I would have went SD or just bought the cheaper 5.7.

I turned off all my WB corrections now my NB O2's are low while my PLX is saying I'm cruising at 12:1.  Bad part is it's never seen lead and only has a few thousand miles on it.  If my car tablet hadn't died the minute I figured that out I would have tuned around it to see what would happen.

It's a reminder to never trust your tools blindly.

Earl, you may be seeing low 02's during cruise...as Eric has lean cruise in his 5.7...and likely 6.1

Depends on which sensor you ask.  NB says I'm good, WB says I'm fat as fuck.



What really sucks is I finally decided to make my car right since my free year runs out in December....   and my tablet fruits out within literally seconds.   Buy a new one minus a HD, seller takes 9 days to mail it...   and it fruits out when I install a drive.

More info for 6.1 users. Below 140 grams per second the NB looks after everything. From 140-220 the WB kicks in for mid boost. Eric himself shuts off mid boost and lets the NB do its thing. I think I read a post from Eric saying the boost comes up so fast that the WB has a hard time tracking it.

A few things from Eric.

Anytime you are using a WB to control fuel you need to pay more attention to it. The amount of time it lasts will vary greatly depending on operating conditions. As an example cold starts have a dirtier exhaust. A car that does many cold starts or just runs for a few minutes will have a shorter sensor life. The key is to monitor your correction and if it changes from the norm then take a closer look. The good thing that when the sensor starts to go bad at WOT they will almost always go lean so the correction goes up and the AFR gets richer.

The AFX unit I have said it needs a 3 amp fuse and a dedicated 12 volts. I went right off the battery with 3 amp fuse under the hood. What I'll do from now on is fire the engine up...and then insert the fuse in the holder. In the past I was doing the opposite. After the run I'd pull the fuse.
