Update: I was able to get the VE and MAF bins dialed in quite close however as soon as I turn everything back on and the truck starts using the O2 information it goes to 15.8-16.1:1 AFR.. The trims...

Does anyone have an .adx file for OS 12212156 that they are willing to share to make this possible? Please
Thank you in advance.

I am trying to get it to work with Tunerpro RT so that I can correlate the AFR with the proper square in the VE table with data tracing ( so far I am recording the screen and wide band with my...

I am in the process of getting this all hooked up and adjusting the settings ( after work and should make more progress this weekend ), but the definitions file (.adx ) that I have does...

EXCELLENT! That is the kind of help that I am looking for and appreciate this very much. I will try to wire the wide band next weekend as described but we threw in the "SD only" bin and made a few...

I will turn everything back on and try to run it.
I do have a wideband (AEM 30-0300 ), but have not been able to get it to log through TunerPro ( Blue pin 68 high and 28 low ).
What I cant...

Obviously I am lost in trying to do this. I tried to follow Goat Rope Garage vid. "GM Gen 3 MAF tuning Intro, The basics For Mass Air Flow", but he is using HP tune and I am using TunerPro RT so some...

Latest: Managed to fail the VE and get it running fairly well on “MAF only”, but still must be missing something because the short and long fuel trims still pull fuel out..? What am I missing here?

Update: I have pretty much soaked this thing in carb cleaner and have yet to find a leak, so right or wrong, I am moving forward with attempting to tune her. I have watched a few videos but...

First off, thank all of you all so much.

Ralmo94 I appreciate the clarification as I was unaware of how it works... Obvious new-b question..How do I "fail the MAF"? It is a swap and has the stock...

Working on an LS swap ( junk yard 6.0L LQ4 with 317 heads ) with 4L80e ( unknown history ) with 0411 computer (OS 12212156). It starts well but goes lean (15.5-16.5 AFR ) as it warms up and stays...

Please try again when you get a chance, It sounds like it is just what I’m looking for.

Right on! Body work is not fun and I have never been good at it so I have a profound respect for the people that do it well. Faux-tina is tough to get right but the beauty is that you just keep...

MO LS Noobie. Excellent advice. In looking at the FPR there was a crack in the boot on the vacuum line. I will replace it an try again.
Thank you.

No hijack intended here, but my issue may be related? Do I need to adjust the same screw or the tune? Any help is greatly appreciated.
I have a junkyard 6.0L with 317 heads, stock cam, stock...

Love that minimalist approach!! LOL Power to weight ratio should be great.
I rarely get to very many of the shows, but would like the opportunity to chat with you in person if you let me know before...

How is the truck coming along?
I have been picking at this for a while and not making a lot or progress but have been able to get PCM hammer and TunerPro RT to work ( starts and runs), just don't...

Hello everyone. We ( my son and I ) are in the process of doing an LS swap and thought that we could dabble in some tuning on a budget to see if it was something he would enjoy and take an interest...
