I just learned how to use a wideband with out pro features!

You can add it in hp tuners to a laptop via usb to serial adapter.

Apparently you can also log your fueling map and it will make corrections that you can paste into your actual fueling map!

My ebl flash does that, but it also writes it to the tune file for you.
I wish hp tuners was that slick.

I still have a loooong ways to go, but things are already making more sense.


Eta, you can replace your narrow band with them and wire a harness from the little processor deal to the orignal harness.
But the recommended is to install a **** just for the wideband.

Goat rope garage on youtube.
I really need to be in the mood for it tho.
GRG ftw. Between that and the book from ERM performance it’s cake. No pro features here and I used an aem wideband that uses obd2 so it can poll faster. 30-0334 is the part number. Goes between the cars obd2 and hptuners. Lambda lambda lambda!

They sell cans of transmission cooler flush at the auto parts stores, just hook it up to the line and push a button until it's empty. Super easy. What kind of a flush tool do you have?
Those rockers weren't what I was envisioning, I was thought they'd be more like the Yella Terra's I put in my 02, shaft mount. Those should be good though. I was told mine add 25 HP, don't know if that's true.
Why did you modify the rocker covers? Is that necessary with the Comp Cams rockers? I know, too many questions. Sorry, I'm bored waiting on stuff.View attachment 343690

I have an ac flush tool that i use to flush lines.
I also have my old ac flush tool that is now an ls oil priming tool.

I use mineral spirits as a flush most of the time.
Paint thinner is what i used for the radiator and the parts that flowed metal.
I had it on hand for the rocker cleanup.

The line flush stuff is just that, but in a compressed air can.
Makes more sense to just use that vs one of those flush cans.
Dollar per dollar that is.

I'm out of paint thinner, and the trans lines will be flushed with mineral spirits.
I alsways have that on hand for use with my ultrasonic cleaner. ;)

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
