Happen to have a link to that book?

And i have a wideband for my vette, the innovative 2 one.
Got it for a great deal on Amazon years ago.
Was a sealed box return, little more than 50% off.

I have spent way more than that in o2 sensor replacements since then.
Seems to be a common complaint.

I'm thinking about grabbing the aem one vs gutting it from the vette.

I also want the gauge as a reference.

Only thing holding me back is that i need a second o2 sensor **** on one of the sides.

And that means the y pipe needs to come off for my welder.

I think the gauge will also help me think in lambda... lol
I really am hesitant about having another hole in the exhaust. I've danced around this with the avalanche since I started it the first time. I really want to learn the narrowband method but I'm really struggling.

I'm the type of person that when I don't understand it, I have a real problem paying attention. I wish I could sit down with someone and go over the basics, like, in person. I've watched all (most) of GRG videos but I feel like he jumps between platforms too much (gen 3 and gen 4).

Once you get the hang of it, I may have some questions. BTW, I've put 1500 miles on the avalanche on the stock tune (I changed the idle and other things for the trans and convertor but fueling and spark is stock)

The good news is one day, a person will only need about a 40 word vocabulary to make it far in this world.

Get to 41 and you can kiss that political career goodbye. :)

He mentions that narrow band tuning is a pita and time consuming.
You can become a patron and get some tuning help, but he says he won't even go into it if you don't have a wideband setup.

I'm taking heed and going that route.
I'll mess with the narrow band at first, but my plan is to just do the wideband.

And i ******* my self with those afr heads i think.
My main concern now will be that i don't run it lean.

ETA: start with the tuning 101 series
he mentions that the vids covering the gen 3 also applies to a bunch of it, and he covers lots of basics there.
I'm still getting there myself, i'm just now starting to get a basic handle on how it works.

my ebl flash was way easier. :D

Mine’s enjoying a day at the spa (dealership). Window regulator replaced and the airbag recall.

This is a dangerous place for me to be. This beauty was here a week ago. Still here, and looking for a home.

Well, damn. I let them change my oil when I was there. Normally I DIY but sometimes while traveling I’m just not in a position to do that.

I have noticed since then she’s been marking her territory, so today I crawled under, and yeah, the oil filter is dripping. Sigh…

So now I’ll go to the parts store and get a new filter and install it properly. Life’s too short to go back to the dealership and hassle over it. If it was my hometown dealer they’d make it right, but these guys and I are just ships passing.

With the new trucks,
I heard there was an RPO code you could get that doesn't have AFM because of the chip shortage...
I don't know if they still come with that 10 speed, iirc it's that ford and gm combined effort.
Hopefully you can also order a 6 speed with it too. ;)


for filter leaks, odd. was it on there really tight?

On a side note,
I started having issues with K&N filters on my vette, started springing leaks after a while.
usually when my oil temps get nice and hot.
I switched to wix and stopped having issues.

I stopped using their filters after that, even though my vette was the only one to have the issue.

How did they install the filter?

Wrong filter, not tight enough, too tight, cross threaded?

So i noticed a little while back that the filter for my wifes 2011 buick enclave v6 has a larger capacity filter that appears to be a match for the tahoe.

I did her oil for the first time the other weekend, and noticed that the prior owner put on a different filter.
Slightly larger capacity than the one that the car calls for.

So i went
:hmmm2:

I ordered a couple to check out.

Tossed one on the hoe for it's first run.

Pretty much flush with the bottom of the pan!!

I think we have a winner.

I just did some spec pulling for some filters in my build thread.
I think i might go with the 2011 enclave filter.
has a oil bypass pressure of 22psi vs the 12 that the hoe's filter calls for.
pn: WL10255XP

Is that better?

What exactly does that mean?

in my brain it sounds better.
Less psi = it will bypass sooner?
Higher bypass psi = force stuff through the filter for longer before it starts to bypass unfiltered oil?
